I used to use dev c++ but now I decided to switch over to codeblocks. dev c++ worked normally but when I try to build on codeblocks nothing happens. I typed out some code compiled it and build it but when I tried to run it a message popped up saying I haven't build it yet and if I would like to build it now. when I clicked yes nothing happend and when I clicked no it would run but not work normally. some youtube videos recommended going to settings then compiler, selecting GNU GCC compiler, going to Toolchain executables and cliicking auto detect. in my case when I clicked auto detect a message saying could not auto-detect installation path of "GNU GCC Compiler". what should I do to fix these errors
install GCC then add its path to environment variable in path then click auto-detect again
if you're on windows
type environment variables in search box
click environment variables button in the dialog
in System Variables group double-click path(add one if missing)
click New then Browse buttons, naviagete to GCC folder
click Ok buttons to confirm, then back to code::blocks to auto-detect
or set the path to GCC manually in Toolchain executables tab
I installed Qt Creator 5.10.1 and when I built the project I had a error : "Could not determine which ”make“ command to run. Check the ”make“ step in the build configuration.”.
I have already install Qt on another PC and I saw this question "Could not determine which "make" command to run. Check the "make" step in the build configuration." Qt creator
but in Tools > Options > Build & Run > Kits I have lot of Desktop Qt 5.10.1 so he have 1.
Sorry for my english as I'm french and I 13 so my skill is limited

You can see the selected build kit in the Build Kit Selector located at the bottom left of your window (button with the hammer image).
You can also manage any of the Build Kits if you go to Tools > Options > Build & Run.
For any build kit in Qt, you need to have the following components:
Device - You can build your application or your desktop/local computer or a remote computer or device with a different or same kind of processor.
Compiler - Specify the location of a compatible C++ compiler here. Clicking on manage takes you to the Compilers tab where you can add as many compilers as you want. If you are on Windows, you will most likely have a MinGW compiler installed along with Qt at this location - C:\Qt\Tools\MinGW\bin\gcc.exe. You can also select a compiler installed with Visual Studio which will be a MSVC compiler.
Qt Version - The last thing you need to specify is the Qmake builder which is in Qt Version. You will need to select this with the appropriate C++ compiler that you previously selected in this build kit. If you have a MinGW C++ compiler, then specify a path for a MinGw qmake.exe and if it is a MSVC compiler then select a MSVC based qmake.exe. On Windows, all your qmake.exe's will be located at C:\Qt\<Qt-version>\<compiler-version&type>\bin\qmake.exe.
Keep in mind that if you are building the project for a different processor or operating system, you will need an appropriate compiler and Qmake selected.
Once you select these properly (and select that build kit in selector), your project will build properly.
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 am a teacher's assistant for a C programming class, and the instructor uses Dev C++ as the compiler for the class. Personally I would use a different one, but the choice is not mine here. Recently I installed the Windows 8 Professional 64 bit that is available on Dreamspark though my university, so I can start with some metro app development for some contests. Unfortunately, Dev C++ has stopped compiling. It previously worked fine with Windows 7 64 bit.
I get an error when compiling that reports back:
Compiler: Default compiler
Executing gcc.exe...
gcc.exe "C:\Users\James\Documents\Homework\TA_CPRE_185\counter.c" -o "C:\Users\James\Documents\Homework\TA_CPRE_185\counter.exe" -I"C:\Dev-Cpp\include" -L"C:\Dev-Cpp\lib"
gcc.exe: Internal error: Aborted (program collect2)
Please submit a full bug report.
See <URL:http://www.mingw.org/bugs.shtml> for instructions.
Execution terminated
Compilation successful
It says the compilation is successful but it is not, so no executable is made. I want to know if anyone has any ideas of what might get Dev C++ to work on this version of Windows, so I don't have to run Dev C++ in a virtual machine? I need it working, so I can do class demonstrations.
Please tell your teacher to update Dev-C++ instead:
http://sourceforge.net/projects/orwelldevcpp/?source=directory
This one ships with a working MinGW 4.7 or a TDM-GCC 4.6.1 (x64) compiler, fixes endless amounts of bugs, and is also portable.
I believe that Dev-C++ comes with a very old version of MinGW (3.4.x if I'm not mistaken). MinGW versions before 4.2.2 will have problems compiling programs on Windows Vista and later unless they are on the PATH.
So you can either update your version of MinGW (as you mentioned in a comment that you have already done), or you can add the MinGW\bin directory to the system path.
If you cannot change your MINGW version, you can try to rename the following file :
MinGW\libexec\gcc\mingw32\3.4.2\collect2.exe to collect2.exe.old
(this solution worked after a migration from W7 to W10).
I received the same error, but was able to get around it by doing the following.
Remove application using add/remove programs
Disable user access controls
Reboot
Download Dev-Cpp 5.4.0 TDM-GCC x64 4.7.1 Setup.exe
Right-click on downloaded file and change to "win7 compatability mode" for all users and select "run as administrator" and click "OK".
Right-click downloaded file and choose "run as an administrator" (note: this shouldn't be necessary, but it's windows so cover your bases)
Choose all the defaults, but on the last screen, deselect "run Dev C++ now" and then select "finish"
Open windows explorer and browse to the install directory C:\Program Files (x86)\Dev-Cpp and locate "devcpp.exe"; right click and choose "win7 compatability mode" for all users and select "run as administrator" and click "OK" (again, this is probably not necessary, but it doesn't hurt anything either).
Double-click the application and pin to your taskbar for ease of use.
Open a new project and test it out, it should work w/o issue.
I used MinGW Installation Manager to download the last version of C Compiler (5.3.0-3 at this moment) and I repliced the files in the folder of Dev-Cpp. Now, its working perfectly in my Windows 10.
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.
