2 (some path)\2 unable to run program file
This happens when the IDE can't find one of the programs needed for compiling your file/project (usually it is make, gcc or g++). There are 2 solutions for this:
1. The "blind reinstall" solution: uninstall Dev-C++ cleanly (pay special attention to the devcpp.ini and devcpp.cfg files if you have Dev-C++ 4.9.x.x), then reinstall the full latest version (see top of this page) in a folder with no spaces in the path. It should work afterwards.
2. The "smart fix" solution: read the compile log to see which program it tried to run; go to Tools - Compiler Options - Programs and see what file it is looking for and in which folder (click the "..." button) and check if it is found in that folder. If the specified file is not there, then select it from the Dev-cpp\bin folder (or wherever you installed your compiler).
Note: if you downloaded the IDE-only version (~2 MB) and you didn't install a gcc compiler (e.g. the mingw package), then you won't find the necessary programs; refer to solution 1.
It might also help to set Tools - Compiler Options - Dire
ca a pas été tres facile mais ca a marché :p
