Cross Compiling - Ubuntu / Windows - MinGW [message #1492541]

Hello,

I am trying to set-up Eclipse CDT to cross compile for Windows. I have Eclipse installed on Ubuntu. I have installed MinGW by using "sudo apt-get install mingw-w64" and I think I've correctly configured Eclipse, including adding "i686-w64-mingw32-" as the prefix in Cross Settings.

I succesfully built a helloworld program for running on Linux/Ubuntu but when building for use on Windows I run into problems. The build fails and in the console the following is displayed:

18:10:01 **** Incremental Build of configuration Debug-Win for project HelloC++2 ****
make all
Building target: HelloC++2
Invoking: Cross G++ Linker
i686-w64-mingw32-g++ -o "HelloC++2" ./HelloCPP.o
/bin/sh: 1: i686-w64-mingw32-g++: not found
make: *** [HelloC++2] Error 127

18:10:01 Build Finished (took 337ms)

No doubt I have failed to configure something correctly, but am at a loss, despite spending several hours scouring the web looking for a solution.

I am quite new to c programming and Eclipse. Any help offered will be greatly appreciated - even if just pointing me in the direction of a suitable tutorial on this topic.

Regards,

Hopefully you have figured out your problem already. I'll offer a few suggestions... Try running the above quoted line on the command line. That may help shine some light on whether the problem is the eclipse setup or Linux. If it works, it is your eclipse setup can't find i686-w64-mingw32-g++. If not, it may not be installed or you may have to add a directory to your PATH environment variable. You can also try the absolute path name for the mingw g++.

Thank you for your reply. I tried what you suggested, but without luck. My system does not seem to recognize that i686-w64-mingw32-g++ is already installed. Please see the below command line text:

user1@system1:~$ i686-w64-mingw32-g++ -o "HelloC++2" ./HelloCPP.o
The program 'i686-w64-mingw32-g++' is currently not installed. You can install it by typing:
sudo apt-get install gcc-mingw-w64
user1@system1:~$ sudo apt-get install gcc-mingw-w64
[sudo] password for user1:

gcc-mingw-w64 is already the newest version.
The following packages were automatically installed and are no longer required:
thunderbird-globalmenu gir1.2-ubuntuoneui-3.0 firefox-globalmenu
libubuntuoneui-3.0-1 openjdk-7-jre-lib
Use 'apt-get autoremove' to remove them.

sudo apt-get install gcc-mingw-w64

Your comments to this problem are appreciated.

I have managed to resolve this issue. I simply removed and reinstalled MinGW, for both 32 and 64 bit - i686... & x86...

Thanks

Please install g++-mingw-w64 if you need c++
