Running a Hello World application in Eclipse C++ in Windows - c++

I've just downloaded and put to run Eclipse C++, in Windows, as well as MinGW (I've set its bin/ directory in the PATH variable).
When trying to compile a Hello World program, I get the following error:
**** Build of configuration Default for project tests ****
(Cannot run program "make" (in directory "D:\lixo\eclipse_cpp\workspace\tests"): CreateProcess error=2, The system cannot find the file specified)
Trying to run the make command from the command line yielded nothing, so I figured out that MinGW's make was called MinGW32_make.exe. I've renamed the file to make.exe, but the problem persists.
What am I missing?

Run the 32bit Eclipse instead, and make sure you're running a MinGW toolchain.
Not a solution, but a generally good enough workaround.

Recipe for target failed error in Eclipse using cygwin

First of all, I know that this question already exists multiple times in Stackoverflow but the answers provided for all of them didn't solve my issue(See section "Solutions worked for others" at the end of this question).
I am using the Eclipse IDE(Juno) with CDT plugin and Cygwin installed in my Windows-7 64-bit platform.
I successfully compiled and run the Hello World 'C' program but the Hello World "C++ program" is having Launch failed. Binary not found error.
I am also having recipe for target project.exe failed error in my auto-generated makefile.
Error line in makefile: #echo 'Building target: $#'
Additionally:
In c/c++ build -> toolchain editor ->
Current toolchain : Cygwin GCC
Current Builder : Gnu Make Builder
Used Tools:
GCC Assembler,
GCC Archiver,
Cygwin C++ Compiler,
Cygwin C Compiler,
Cygwin C Linker,
Cygwin C++ Linker.
When I change Current Builder from "Gnu Make Builder" to "CDT Internal Builder" the recipe for target project.exe failed error disappears but the Launch failed. Binary not found error still exists.
And also I dont have MinGW installed.
Solutions worked for others :
Before running the project directly using the run command, first Build the project and then run.
I build the project every time before I run it.
Eclipse can't find or point to an .exe file but the exe file runs fine when run from windows explorer and the answer to it is add -arch i386 to miscellaneous under linker.
My build runs without error but not creating the exe file. So this doesnt apply to me
Project->Properties->C/C++ Build->Settings->Binary Parsers
set "Cygwin PE Parser" and/or " PE Window Parser" and alike.
Tried all of them with different combinations but did not work
I also did :
adding the cygwin install dir to the path variable
added all the includes folders needed for cygwin for both GNU C and GNU C++ in Paths-and-Symbols -> includes
Saved the project before building and then running
restarted eclipse again
checked if g++ is installed using which g++ in terminal
and so on.
What could be a fix to this problem? Or do I have to install MinGW (I tried already to install MinGW with the installer.exe they provided and it failed on downloading the files several times) and try again.
I couldn't find the solution. Please show me what am I missing here.
Thanks in advance.

What do I have to do to set C++ development in eclipse?

I am currently trying to set my eclipse so that I can start c++ development on my Windows computer. However, I am stuck with some errors. But first, here is what I did so far:
Installed the CDT for Eclipse
Installed Cygwin (with the additional packages gcc, gcc and make)
Added all "paths for headers" in Eclipse
The problem is that when I try to run my Hello World program, I get Launch failed. Binary not found.
I already build and rebuild the project but the program is still not running. It must be because of these errors that I have:
/bin/sh: g++: command not found
make: ***[src/HelloWorld.o] Error 127
What can I do to solve these errors?
Try running the Cygwin setup.exe again and select the packages for g++. Search for that and make sure those are installed. It should be under the name gcc-g++. The C++ compiler is installed separately from the C compiler.
Ok, I figured it out by myself. Since this really freaked me out, I want anyone else who has this problem to know how I solved it.
So apparently, since I had g++, gcc and all that installed, it had to be a problem with the path.
So what I did was check my path. If you don't know how to edit it, check this link http://www.computerhope.com/issues/ch000549.htm
So in there, I chose Path under the System variables and clicked on Edit.... What I noticed was that instead of C:\cygwin64 it said C:\cygwin. All I did was append the 64 (since I had installed the 64-bit version of cygwin) and I was done.
I restarted Eclipse, cleaned and built the project and the errors where gone!

Eclipse CDT Binary not found - Mac OS X Lion

On my MacBook Air I need to use Eclipse to make some c++ programs for school. So I downloaded Eclipse for C++ from the eclipse.org and made a little Hello World program. However, when I try to run the program, it just gives me the error "Launch failed. Binary not found".
When I try to build the program, this is the output:
**** Build of configuration Debug for project HelloWorldC ****
make all
Cannot run program "make": Unknown reason
Error: Program "make" is not found in PATH
PATH=[/usr/bin:/bin:/usr/sbin:/sbin]
**** Build Finished ****
However, I tried to make a hello world application in Xcode and that works perfect...
Unfortunately, I cannot use Xcode because the teacher is only allowing Eclipse projects...
I found the solution.
The problem is that you can install the latest Xcode (4.3) only from the app store, and by default it seems like the c++ compiler is only accessible through Xcode, to solve this you need to:
Open Xcode
Go to Preferences
Go to Downloads
Install Command Line Tools
Make sure the "UNIX Development Tools" are installed with the Xcode installer.
I don't have Eclipse here, but on my Mac book which make gives me:
correa$ which make
/usr/bin/make
which is one of the paths it's looking for.
If I remember correctly, it was installed simply installing Xcode from the app store. You should try to check if make is really installed in your system, if not, you could try reinstalling xcode to see if it fixes the problem.
Hope this little bit can give you a starting point. Can't yet comment on the question, otherwise would have just made a comment.

Netbeans and MinGW-w64

I'm trying to configure my NetBeans on win7 64bit, to work with the MinGW-w64.
So I put in the %PATH% variable the following paths of the compiler:
C:\mingw-w64-bin_i686\mingw\bin
C:\minGw-MSYS\msys\bin
C:\mingw-w64-bin_i686\libexec\gcc\x86_64-w64-mingw32\4.7.0
Then I opened NetBeans and this was configured:
The configuration in NetBeans
I tried to compile a little test program but I received this error:
g++.exe: fatal error: -fuse-linker-plugin, but liblto_plugin-0.dll not
found compilation terminated. make[2]: *
[dist/Debug/MinGW-Windows/test.exe] Error 1 make1: [.build-conf]
Error 2 make: ** [.build-impl] Error 2
BUILD FAILED (exit value 2, total time: 1s)
I do have this file in C:\mingw-w64-bin_i686\libexec\gcc\x86_64-w64-mingw32\4.7.0
what am I missing?
Right, after months of putting this off I've finally sat down and done it. I'll probably make a more detailed post on my blog with pretty pictures but here is a trimmed down SO version which will hopefully be enough for you (and everyone else) to get going with.
Prerequisites
Remove MinGW, MSYS and CMake if you have them and can afford to lose them (we will reinstall MinGW (obv.) and MSYS but not CMake as it doesn't appear to be needed.)
Netbeans or other suitable IDE
64bit Windows.
EnvMan (optional but handy for managing Windows Environment
variables.)
Installation
MinGW-W64 C compiler and MSYS
Download and install MinGW-W64
http://mingw-w64.sourceforge.net/ (link is on the left menu with a
hyperlink called 'WIN64 Downloads'.)
There are a lot of versions which can be a bit complicated. We are
going with mingw-w64-bin_i686-mingw_20111220 (although the numbers at
the end may be different) which basically says we want the version
with the windows binaries.
Once the download is complete (about 300mb so 10min or so) extract to
C:\MinGW-W64 or similar. Make sure there aren't any spaces in the
path!
Download MSYS for MinGW-W64
Took a bit of searching
http://sourceforge.net/apps/trac/mingw-w64/wiki/MSYS is the wiki for
it and
http://sourceforge.net/projects/mingw-w64/files/External%20binary%20packages%20%28Win64%20hosted%29/MSYS%20%2832-bit%29/
is where I found the download and the version I went with was
MSYS-20111123
Once the download is complete extract the files to C:\MSys or
similar. Make sure there aren't any spaces in the path!
Setup
Add 'C:\MinGW-W64\bin' to your Windows PATH variable.
Add 'C:\MSys\msys\bin' to your Windows PATH variable.
Start Netbeans and go to Tools -> Options -> C/C++.
Click 'Add' under 'Tool Collection' and select the base directory of
MinGW-W64 (C:\MinGW-W64\bin).
Select 'MinGW' from 'Tool Collection Family' if it isn't
auto-detected and click 'OK'.
Set the 'C Compiler to C:\MinGW-W64\bin\x86_64-w64-mingw32-gcc.exe.
Set the 'C++ Compiler to C:\MinGW-W64\bin\x86_64-w64-mingw32-g++.exe.
Set the 'Make Command' to C:\MSys\msys\bin\make.exe.
And that should be it!
I should note that I am using the system to compile a library file to be use via JNI so have some additional steps for that which I missed out as they weren't needed here. However I made a quick 'Hello World' program and it compiled and ran nicely.
Happy coding!
I have just downloaded the latest automated build, unzipped it, added the main bin directory to path, and run:
x86_64-w64-mingw32-gcc test.cpp -o test.exe
and
x86_64-w64-mingw32-gcc -fuse-linker-plugin test.cpp -o test.exe
and it works. The same for the i686 variant. Your IDE is doing something wrong. Or you shouldn't have messed with the files. Or you shouldn't have removed the prefixes. Seriously.
PS: You only have to add the main "bin" directory to PATH, all the rest is wrong.
With some searching via your favorite Internet search engine, I have come across a better approach to quickly add MinGW-x64 to a Windows 64-bit system. On the Sourceforge site is MSYS2.
While following the installation directions and obtaining the most up to date packages, there may be a time out at the primary mirror site on Sourceforge. If so, follow the mirror site update directions and update the three pacman text files in the respective MSYS2 directory (e.g. /etc/pacman.d). Then proceed to complete the package updates from the MSYS2 installation directions.
Within the MSYS2 packages are things like gcc, llvm, make, dmake, etc. Here is the command used from the MSYS2 command line shell (e.g. bash) to install the GNU make utility:
$ pacman -S msys/make
The executable location it will be placed is: /usr/bin inside the MSYS2 command shell. As far as configuring Netbeans for where make.exe is located, the Windows path is:
MSYS2 installation directory\usr\bin\make.exe
(e.g. C:\msys64\usr\bin\make.exe).
To successfully build C++ with Netbeans, I used the GNU make package (e.g. msys/make). Then in order to use the default make files that Netbeans manages, and to not interfere with other C++ compilers within your Windows installation (e.g. Visual Studio, Intel, CLang from Visual Studio, etc.), run Netbeans from the MinGW-x64 command shell provided by MSYS2. In this way, the environment variables and other things like:
ls rm mkdir
will indicate successful execution and compilation within the Netbeans internal terminal window. I opened the MinGW-w64 Win64 Shell by navigating to the installed shortcut from MSYS2's installation. Then pasted into the MinGW-x64 shell command line, the Target property value from the Netbeans Windows desktop shortcut:
$ "C:\Program Files (x86)\NetBeans 7.4\bin\netbeans.exe"
And then could finally create the respective debug and release object and executable files. I also modified the Netbeans project output to be within the MSYS2 directory structure. Then run the executable within the MSYS2 MinGW-x64 shell. Running from the Netbeans IDE produces this error message:
Unable to start pty process: The application failed with exit code
-1073741515 (0xc0000135).
If the MSYS2 path were in the computer system's PATH environment variable, then perhaps this error would not happen.

g++ not working on Windows command prompt. Cygwin installed

I have installed Eclipse and CDT (to use C/C++ in eclipse CDT is needed), as well as installing Cygwin so that I can compile my files.
In environment variables I've set Path to include the following: "C:\cygwin\bin;"
g++, make and GDC are all installed via Cygwin. I made sure of this by searching for them in the bin folder - they're all there.
If I enter "make" into the windows command prompt, this appears:
make: *** No targets specified and no makefile found. Stop.
If I enter "g++" or "gdc" into the windows command prompt, this appears (or similar):
'g++' is not recognized as an internal or external command,
operable program or batch file.
So, in other words make is working but the rest isn't..but they're in the same bin folder! Has got me completely confused.
If I attempt to open Cygwin Bash Shell, g++, make and GDC all work there.
However, I need it to work in the command prompt so that Eclipse is able to compile the programs I write in the IDE.
If you know why this is happening, please let me know.
I haven't used cygwin much, but my understanding is you have to use it from the cygwin bash shell.
if you need g++, make, etc, use mingw, with it, g++ works from the normal windows command line.
Here is what happened to me and how I fixed it.
My C:\cygwin\bin\g++.exe is a shortcut pointing to C:\etc\alternatives\g++.exe, which points back to C:\cygwin\bin\g++-3.exe.
Replacing g++ with g++-3 worked for me.
In C:\cygwin\bin see whether g++.exe is there. If not, the installation wasn't done properly and you may need to install again. That's what was my problem and it's resolved :)
Adding the cygwin paths to the Path variable worked for me (windows 8.1 64 bit):
Go to system properties and select advanced system properties
Go to environment variables and select Path in system variables, click edit
Add the Cygwin paths...
for 32 bit:
C:\Cygwin\bin;C:\Cygwin\usr\bin
for 64 bit:
C:\Cygwin64\bin;C:\Cygwin64\usr\bin
In the CMD window, try typing bash to start a bash shell in that window. If that doesn't work, then the cygwin bin directory is not on your path.
If it did work, enter type g++ and type make to see the paths that are being used for these commands. I'm pretty sure your problem is with your PATH variable.
You could install a Windows version of which to get some help in figuring out exactly which executables are being run.
Perhaps it's picking up 'make' from somewhere completely different, and your addition to %PATH% is not working.
Also verify it by typing echo %path% in the same command prompt window as you're seeing the problem in, just to make sure.
