I just did the default Java (8) installation of Eclipse on my Windows (8, yikes) laptop, and it seems to work just fine. However, I'm not as good at Java as I am with C and C++, and for some work it's more expeditious to use C/C++ than Java.
Unfortunately, the Eclipse installer for Windows doesn't make it very easy to set up Eclipse for C/C++. It looks like I'd be fine with Linux or BSD, but then I'd have to scrounge up another laptop (because I need the mobility) and install Linux or BSD on it. Yes, I need to leave Windows on this machine, so Windows hate isn't going to help me.
My lazy web search turned up this article: "Install Eclipse for C++ Development on Windows 7 64-bit". Is there a better installation guide than that, or does anyone care to describe the process in more detail?
Even though you have CDT features installed, you need to install a GCC compiler for windows such as MinGW or Cygwin. Once you install them, add the 'bin' folder in the installed path to the environment variables and then restart eclipse. You should now see MinGW compiler when you select "Create new C Project". After this step, proceed with your C programs and this should resolve your problems.
You will have to install a GCC compiler in your PC and then link it to the project each time you create a project. This can be done while you create a new project, or even after you have done so. You can download MinGW compiler through the following link
https://sourceforge.net/projects/mingw/files/latest/download?source=files
Once you have downloaded the compiler and installed it, it can be linked through the following steps:
i. While creating a new project, choose MinGW GCC compiler in the tool chains.
ii. Once you have finished creating a project, go to Project->Properties.
iii. Look for Run/Debug Settings in the left panel.
iv. Click on the New tab and select C/C++ Application.
v. Look for Environment option.
vi. Click on the New tab.
vii. Type "PATH" in the Name bar and fill the Value bar with the path of the compiler. For me, its C:\MinGW\bin.
vii. Click on OK and you are done!
The instructions you link to have you install Eclipse IDE for C/C++ developers which will work fine to get a C/C++ development environment up.
If you would instead like to use your EXISTING installation of Eclipse and add C++ Development Tooling (CDT) you can launch Eclipse and then use Install New Software to install the C/C++ Development Tools
I had good times debugging Java applications on Eclipse, but recently that I'm working on a C/C++ on Ubuntu 12.04 using Eclipse CDT, it ignores the breakpoints when debugging! I've tried two versions of Eclipse CDT, CDT 8.4.0 for Eclipse Luna, but doesn't work either. Can somebody help with that?
NOTE: I know there are some other similar questions, but I was thinking it is better to ask this question which specifically addresses CDT 8.4.0 for Eclipse Luna.
The eclipse-cdt is shipped only with the required tools for building c/c++ applications. It does not ship with gdb. You need to install that separately
How do I use GDB in Eclipse for C/C++ Debugging?
From link above these are the steps to follow.
1. Go to Help > Install New Software.
2. Add the CDT repository http://download.eclipse.org/tools/cdt/releases/8.4 to the list of repositories.
3. Select the CDT Repository. Now you need to install the CDT plugin along with GDB support from the list of available plugins (Select the CDT Main Features as well as CDT GNU Toolchain Debug support).
I updated the CDT repository path to correspond to your release (Luna).
It also happens for me in ReadHat 64
Seems like if the CDT breakpoints are not suitable for the current debug session, in the breakpoint window, when enabling "Show breakpoints Supported by selected target" all my breakpoints disapears from the list.
In my case, my ELF have debug info and all the breakpoints that I place are in the main ELF.
My debug settings worked fine with the former Eclipse version.
I rolled back to eclipse Juno, and my debug session with same elfs worked out of the box.
Experiencing the same problem here.. I am working around it by manually setting breakpoints after starting debug session. Console -> gdb, then type "break xxxx".
If you're using MinGW gdb, check that C:\MinGW\bin is in your path (set in System Properties). Made all the difference for me.
I once had Skip All Breakpoints accidentally checked, and was wondering what was going on.
I have the same problem with my eclipse Photon, I figured it out by unchecking the
"stop on startup at: main" in Debug Configuration-->Debugger.
I know this in Rikard Söderström's response to you.
I'm trying to create a C++ project on eclipse. I have installed eclipse-cdt for that.
While creating a project, a pop up window asks for cross compiler prefix and cross compiler path. Could someone please explain what are those and what do I need to add in those fields? Are those fields absolutely necessary to fill?
If you are using a Mac, you can select MacOS GCC instead of Cross GCC. If you are on Windows, you will have to install a C++ compiler. I recommend you install Cygwin, try following the directions here.
https://www3.ntu.edu.sg/home/ehchua/programming/howto/eclipsecpp_howto.html
Once you've installed the C++ compiler, restart Eclipse and try to create the project again. Hope this helps.
In Cross compiler Prefix you need to write 'arm-none-eabi-' and in Cross compiler path you have to select the path for GCC bin folder. You need to install Cygwin GCC for this.
I have found few steps in below link.
https://www3.ntu.edu.sg/home/ehchua/programming/howto/Cygwin_HowTo.html#cygwin
Just in case anybody else is like me and needs more explicit directions as #yeremy is correct in that you have to select MacOSX GCC. It's just that at the point where the OP is, he overshot where he could have made the selection and needs to back up a few windows (about 3) to choose the MacOSX GCC as the Toolchain of choice. Attaching a link below which goes through the steps and which also shows image of window where you can make the selection (figure 11).
Getting Started with C++ for Eclipse - CodeGuru
When Eclipse doesn't detect a toolchain (to be installed separately) it only offers the option "Cross GCC". Don't choose that.
Sites like this tell you that a properly installed toolchain (Cygwin / MinGW) is automatically discovered using the PATH environment variable. This is not the case on my machine.
There's no way to configure a toolchain in Eclipse manually (as of writing) but you can fool Eclipse into finding one without changing your global PATH:
Go to Preferences/C/C++/Build/Environment,
Add a variable PATH and point it to your toolchain path(s), e.g. d:\Mingw\bin;d:\Mingw\msys\1.0\bin. Separate paths with a semicolon.
For newbies just starting out C++ projects in Eclipse:
1 - Click File --> New--> C/C++ Project
2 - In the "Templates for New C/C++ Project" window, Select C++ Managed Build --> Click Next
3 - Provide a project name --> Select "Empty Project" in Project Type section (which is under Executable) and Select "MinGW GCC" in the Toolchains section
4 - Click Finish
Note: Selecting "MinGW GCC" will eliminate the headache of inputting the Cross GCC related prefix and path. Happy C++ learning.

I have gpp installed in my Windows 7 (32 bit) as shown in the picture.
PATH variable gas g++
"%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;%SYSTEMROOT%\System32\WindowsPowerShell\v1.0\;C:\cygnus\cygwin-b20\H-i586-cygwin32\bin\g++"
Still eclipse shows the error:
"Program "g++" not found in PATH".
How can this be resolved?
Today I have bumped into this problem and solved it in the following way. I pressed "Reset defaults" button everywhere I could find it in Eclipse settings (for example, Preferences/C++/Build/Settings/Discovery). After that the error disappeared and the code compiled successfully.
This is how I got rid of it:
Install the MinGW.
Select all files in the Basic Setup and select apply the changes.
Select new C++ Project You will be able to see "MinGW GCC" in the toolchain section select the same and create project.
You need a gcc, g++ compiler toolchain (on your windows machine) for the eclipse which you have manually downloaded,
One of the options can be done implicit via cygwin installation(by selecting proper development packages for gcc, g++) and then add the location of the compiled gcc ,g++ package like C:\cygwin\etc\alternatives to the PATH variable for windows environment.
After this open eclipse and go to Project->properties->C/C++ Tool Chain Editor and add replace default GNU C++ compiler and GNU C Compiler with Cygwin C++ compiler and Cygwin C compiler and rebuild the project. The errors related to gcc, g++ PATH not found will now be gone.
You need:
C:\cygnus\cygwin-b20\H-i586-cygwin32\bin
in the PATH.
and not
C:\cygnus\cygwin-b20\H-i586-cygwin32\bin\g++
as you wrote.
I got the same problem with mingw-64 (x86_64-4.9.1-release-posix-seh-rt_v3-rev1), Eclipse Luna 4.4.1 and CDT 8.5.0.201409172108, using Windows 7.
I solved this problem by putting the following two environment variables under
Window -> Preferences -> C/C++ -> Build-> Environment
name: MINGW_HOME value: (mingw installation directory without "\bin")
name: MSYS_HOME value: (msys installation directory without "\bin")
You can check
Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC
Built-in Compiler Settings MinGW [ Shared ]
, if it doesn't complain "Toolchain MinGW GCC is not detected on this system" then you're all set.
I had the same problem, the only solution that worked for me was this:
Open command-line and check whether "g++" actually executes the compiler
If (1) works, uncheck Project->Build automatically in Eclipse
Clean project
Build project
I had the same problem: Eclipse couldn't find (g++) and (gcc) in PATH even they were accessible from command-line. I was also sure they are pointed by PATH correctly.
I have just deleted the (.metadata) folder from Eclipse's Workspace as a mean to reset it and this worked for me.
The PATH is locate at Project Properties > C/C++ Build > Environment (see screenshot below).
For your reference, I am using MinGW, I got the same error before I got the MSYS install. Later I found out that I also need MSYS to be install because the make.exe wasn't come with MinGW. (I don't this error was cause be MSYS.)
After MSYS is installed, add MSYS and MinGW path into environment variable, restart Eclipse. Remember to rebuild your project in order to rectify the error. If error still persist after restart, recreate the workspace. At least this has solved the problem on my site, hopes this help on you too.
Good luck!
I had a similar problem. The error is raised, but the code is compiled and linked. The error was caused by the Error Parser using a different configuration than the one that is compiled.
The error parser configuration was only valid for the Linux configuration of my software. My active configuration was set for MinGW and Windows.
Solution:
In Elipse under Windows->Preferences->C/C++->Indexer set Build Configuration for the indexer to Use active build configuration.
Clean and rebuild, otherwise the old errors will remain visible
Maybe it has nothing to do here, but it could be useful for someone.
I installed jdk on: D:\Program Files\Java\jdk1.7.0_06\bin
So I added it to %PATH% variable and checked it on cmd and everything was ok, but Eclipse kept showing me that error.
I used quotation marks on %PATH% so it reads something like:
%SYSTEMROOT%\System32;"D:\Program Files\Java\jdk1.7.0_06\bin"
and problem solved.
I had similar problem and I solved it by:
Installing g++ The GNU C++ compiler using Ubuntu Software Center
Changing in: Window -> Preferences -> C/C++ -> Build -> Settings -> Discovery -> CDT GCC Build in Complier Settings [Shared]
from: ${COMMAND} -E -P -v -dD "${INPUTS}"
to: /usr/bin/${COMMAND} -E -P -v -dD "${INPUTS}"
I hope it helps.
I had the same problem in Sublime..
Right click on my computer
Advanced system settings
Environment variables
in system variables, change path to location of '...\MinGW\bin'
Example: D:\work\sublime\MinGW\bin
For me it got fixed with:
Go to:
Window -> Preferences -> C/C++ -> Build -> Environment
Then press "Add..."
Name: MINGW_HOME
Value: C:\MinGW (yours might be different if you choose a custom path)
Hit "Apply and Close"
Now, it shoud work if you did everything correctly
i think cgywin might not work for you as you can only compile your code in Win7 if you fire up the command prompt; you need to use MinGW compiler toolset instead. After you have install your compiler, go to Properties->C/C++ Build->Tool Chain Editor -> Change your current toolchain to MinGW GCC.
WINDOWS 7
If there is anyone new reading this, make sure to simply try a clean install of mingw before any of this. It will save you sooooo much time if that is your problem.
I opened up wingw installer, selected every program for removal, apply changes (under installation tab, upper left corner), closed out, went back in and installed every file (in "Basic Setup" section) availible. after that eclipse worked fine using "MinGW GCC" toolchain when starting a new C++ project.
I hope this works for someone else.
If not, I would do a reinstall of JDK (Java Developer's Kit) and ECLIPSE as well. I have a 64bit system but I could only get the 32bit versions of Eclipse and JDK to work together.
In my case, I didnt mark for instalation the mingw32-gcc-g++ package in the installation manager, that's why eclipse didn't know it.
Needed to go to the instalation manager, mark it (in basic setup tab) and update catalogue
If you have your PATH setup and you can see g++ --version via the command line, then try to delete the project and create a new c++ project.
So the reset defaults might work but I think it has to update the PATH if it wasn't added before.
Had this problem on windows 10, eclipse Neon Release (4.6.0) and MSYS2 installed.
Eclipse kept complaining that "Program 'g++' not found in PATH” and "Program 'gcc' not found in PATH”, yet it was compiling and running my C++ code.
From the command prompt, I could run g++.
Solution was to define the C++ Environmental variable for eclipse called 'PATH' to point to windows variable called 'path' also $(Path).
Menus: Preferences>>C/C++>>Build>>Environment
Looks like eclipse is case sensitive with the name of this environmental, while windows doesn't care about the case.
First Install MinGW or other C/C++ compiler as it's required by Eclipse C++.
Use https://sourceforge.net/projects/mingw-w64/
as unbelievably the download.cnet.com's version has malware attached.
Back to Eclipse.
Now in all those path settings that the Eclipse Help manual talks about INSTEAD of typing the path, Select Variables and
**MINGW_HOME**
and do so for all instances which would ask for the compiler's path.
First would be to click Preferences of the whatever project and C/C++ General then Paths and Symbols and add the
**MINGW_HOME** to those paths of for the compiler.
Next simply add the home directory to the Build Variables under the C++/C Build
Build Variables Screen Capture
All the tips did not work for me using the Gaisler Tools for GR712RC Installation for OS RTEMS.
I'm using the Eclipse Kepler.
The simple way was making a copy of sparc-rtems-gcc.exe to gcc.exe, and sparc-rtems-g++.exe to g++.exe, in the C:\opt\rtems-4.10-mingw\bin directory.
The reason is that eclipse cannot find your gcc or g++ environment variable path.
You might have tried to run c or c++ or fortran but eclipse cannot find out the compiler.
So, add the path in your environment variable.
Windows -> Search -environment variables -> click on environmental variables at bottom.
Click on path ->edit -> new -> your variable path
Path should be entire, for example:
C:\Users\mahidhai\cygwin64\usr\sbin
Make sure that the variable is permanently stored. It is not erased after you close the environment variables GUI.
Sometimes you might find it difficult to add a path variable.
Make sure windows is updated.
Even if Windows is updated and you have problems, directly go to the registry and navigate to the below.
HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\Environment
Add your path here. Remove any unnecessary repetitions of path variables.
Note:
You need to add your path variables in system environment variables -path
enter image description hereIf you just want to run C program but meet this error, it might mean that MinGw c++ compiler has not been installed even if "C:\MinGW\bin" has already been added to Windows Path variable.
Solution:
Run "mingw-get-setup.exe" to open MinGW Installation Manager
Open All Packages->MinGw->MinGW Base System->MinGW Compiler Suite
Select the following compilers to install:
. mingw32-gcc-g++
. mingw32-gcc-v3-core
. mingw32-gcc-vc-g++
Click Installation->Apply Changes to apply the above changes
Wait for the installation finishing(There might be some errors, just ignore them).
Restart Eclipse.
Done.
It Worked in my environment.
Hope it works in your case.
I am quite troubled as this shouldn't be causing me such a headache. I've downloaded the most recent Eclipse Indigo and all CDT C++ plugins for MAC OS X 10.7.1/
Upon restarting after installing the above CDT plugins, I've developed a simple 'hello world' c++ application and have tried running the application, "Launch failed. Binary not found." error message. I've read multiple fixes but none have worked. I tried adding the -arch i386 flag to the linker and compiler commands, still no luck.
Has anyone successfully gotten Eclipse C++ running on 10.7.1?????? This blows my mind. I can simply write the same program in VIM and compile it just fine via the terminal and execute just fine. ECLIPSE DOESN'T WANT TO PLAY ALONG.
I will be deeply indebted to anyone who can help!!!!!

I am using Eclipse Juno with CDT on a 2007 Macbook running Snow Leopard. I have the two symptoms:
No Binaries folder in Project Explorer, and
The 'Launch failed. Binary not found' error.
I have spent hours searching on Google for an answer, long enough to ascertain that these two symptoms are indicative of any number of problems which have been reported for not quite a decade without adequate resolution. That is a problem right there because after a decade there should have been more than enough input data to provide one troubleshooting procedure somewhere which walks the user step by step through the elimination of all possible causes.
Instead, for hours I have read about a multitude of people, many of whom have resolved their particular problem but all of them seeming to have had to do something slightly different to get there.
This should not be that difficult to resolve. Particularly in cases such as mine [but I am not the only one] when the Console view displays a Build with no errors yet the user can copy the binary file [which Eclipse bizarrely says it can not find] to the Desktop and run it without any problems from either Finder or a bash terminal session.
All of this seems to be pointing rather emphatically toward the lack of adequate indicators in the Mach0 64 binary parser which should be designed to tell us exactly what it needs which it is not seeing.
Admittedly, this is exacerbated in the case of MacBooks like mine which are running a 64bit OS [Snow Leopard] on a 64bit CPU which the manufacturer, unfortunately, hamstrung with a 32-bit bootup kernel. But, be forewarned, I have already tried the -arch i386 g++ switch, and the relinking of g++ to g++-4.0 without any change in the symptoms.
ADDENDUM ADDED 10/07/2012:
I am adding this checklist in the hope of clarifying a Way for the undoubtedly many others who will ask this question in the years to come. This Way reflects what I found to be necessary when using Eclipse Juno with a Mac running Snow Leopard:
1) Go to Preferences->C/C++->New CDT Project Wizard, and under Preferred Toolchains, make sure all the Executable project types are set to MacOSX GCC.
2) This is a biggie. I was able to get a Binaries folder in Project Explorer, and hence be able to run the project after building it, by using a Project name which does not contain dots ['.']. This I learned from another answer here, edited a few hours after my previous message. This requirement is easy to miss, hence a common one particularly if you are Eclipse experienced but only with other languages, because tutorials for other language plugins [such as with PyDev or for Java] frequently have you create Projects with dots in the name. If you have developed that habit with other languages, break it when using CDT for C/C++. Be forewarned, however, that it is not enough to just do a Right-Click and Rename an existing project name this time not using dots. The simplest Way is to delete your old project and create a new one with a name without dots.
3) There are many websites cautioning you to make sure you either use the -arch i386 compiler switch or change the links for /usr/bin/gcc and /usr/bin/g++ to point to gcc-4.0 and g++-4.0 instead of gcc-4.2 and g++-4.2. I created a bash script to ease switching back and forth and investigated if this was necessary. It was not, at least not with my Macbook. Based on what I read at one site from a Mach-O developer, I suspect that the current version of Mach-0 64 goes both ways. Which is a good segue to ...
4) In the Project Properties, not Preferences, go to C/C++ Build->Settings and under Binary Parsers make sure Mach-O 64 Parser is checked. Make sure this, and not the deprecated Mach-O parser, is checked.
5) At this point, after you build your project, several things should be evident in the Project Explorer:
6) There should now be a Binaries folder under project's folder.
7) Within that Binaries folder should now be your executable file. It should have [x86_64/le] next to it if, like me, your Mac is effectively 32bit. Now is not the best time to get into the confusing topic of whether your Mac is effectively 32bit or 64bit. If you do not know, and a lot folks don't because Apple does make it confusing, check out the little app which can be downloaded from http://www.ahatfullofsky.comuv.com/English/Programs/SMS/SMS.html which will tell you What Is Truth. It is free, but the 'price' is that you have to scroll pass the ads at the top of the page reflecting the programmer's political disposition.
For those of you that are new to programming/eclipse/IDEs and get the same error but the solutions above don't work, I solved my "Launch Failed. Binary Not Found." error by doing the following: Simply be sure to build your project ("Project" > "Build All") before attempting to run or debug. I was thinking that the IDE would do the building when I clicked debug or run, but that is not the case (obviously, in retrospect). Newbie lesson learned. Once you build you should see a "Binaries" and "Debug" folder under the root directory of the project.
I was using OS X 10.7.3, if it matters, though I assume the mistake I made is fundamental and any eclipse distro would give the same error.
on mac:
Make sure you have xcode installed. Test it by writing "info g++" you must see proper information about the compiler.
Build your project.
Go to the folder of your project. You should see an executable file in Debug or realise folder, depending to your building configurations. If you d-click on the executable file you should see the result on the terminal.
Back to Ecliipse, from Run/Run Configurations... and then browse to the folder that you have the executable file - one you already found - you can also change build configurations as you wish in that window. And make build automatic for each run.
Run again it should work.
Good luck !
I had the same problem, then I found a solution on this site.
Let me explain shortly;
Create your c++ project,
Have a look at project properties(⌘I),
Select Mach-O parser under binary properties,
Write your codes down,
Do not forget building your project (⌘B) before run.
You should change the settings for your project to build an executable instead of a dynamic library:
Invoking: MacOS X C++ Linker g++ -arch i386 -dynamiclib -o "libHelloWorld" ./main.o`
Go to project properties -> C/C++ Build -> Settings -> Build artifact, and select Executable in the first drop down list.
I am using Eclipse Oxygen and the following fixed my problem:
Right-click on your project and go to properties. Navigate to C/C++ Build > Tool Chain Editor and select MacOSX GCC in the Current toolchain, and Apply and Close.
Build your project with CMD+B and then run it.
I was having the same problem. The answer can be hard to find as the "binary not found" issue has cropped up several times before, with different causes and solutions (selecting the 64-bit parser, etc.).
It turns out that, in my case, the fix was simple: you have to do a manual build, just once, for every new project you create. After that, works as usual.
Details: using a fresh fresh install of Eclipse Indigo Service Release 1 on Mac OS 10.7.2.
If your project name contains a "." (dot), the binary file will not be generated on building project.
Remove all the "."(dots) from the project name and rebuilt it or try creating a new project.
Happy coding!
If you can successfully built but when try to run it getting error:
Possible solution could be adding new configuration with full path to your binary output file
(Run->Run Configuration...->Main->C++ Application):
I solved a similar problem with Eclipse by creating a "Launch Configuration". I am using the Indigo release of Eclipse on OSX Lion with CDT (C/C++ dev environment). I found the option to create a new launch configuration in Project->Properties->Run/Debug Settings.
I encountered this problem after creating and building an empty "Hello World Ansi C Autotools Project". The build process created a working executable as src/a.out. I could run a.out successfully from the terminal but Eclipse did not understand that this was an executable for my project until I created a launch configuration pointing to it. Once I did that I was able to run a.out as usual using the green run button.
I had the same problem, even when i had set the artifact to executable. It was because the shared lib setting was ticked and this causes a dylib to be made even though you have specified an executable.
I go this to run by setting the Builder Type to Internal Builder on the C/C++ Build tab, in the project properties dialog.
No matter which approach to take to solve this issue on your workspace, this problem seemed to have become native to the project that I had created. Neither using the arguments or making sure the gcc version for linking did not work. I did find an intuitive solution. Here it is:to the "...binary not available..." error.
Do the following:(remember the following steps are after you have taken either of the above routes and none of those have solved the issue.
1.) delete everything - the project and the files.
2.) create new project and source files
I had the similar issue but code was different. In File.h file make sure
virtual ~Destructor () {}; //Don't forget Curly braces {}
Above statement shows destructor initialized () and defined with curly braces { } . In my code I forgot to define Destructor.
Hope this helps
I was having the same problem, so I fiddled around a littpe bit and found out that if I clicked on the "profile" button (green play icon with a little clock under it), to the right of the "run" button, my program would Run the next time I clicked on the Run button.
I actually dont know what that did, but it allowed me to run the code.
if anybody knows why this helped, and whether it is an actual solution or not dont hesitate to relpy!
