    Then I'd use the full path to it in your application rather than relying on that. The working directory may not be the same as the one your program is stored in.

    You can use QApplication::applicationDirPath for that.

        I add my next verification :

        if(lancementDuProgrammeROI()){
             if(processusROI.exitCode() == 0){
                  /*TO DO*/
             }
              else if(processusROI.error() != 0){
                   QMessageBox::warning(this, "Erreur", "Le programme roi a planté.\n"+statutDeLApplication.number(processusROI.exitStatus())+" : "+processusROI.errorString());
             }
         }
        

        I obtain this :
        erreur_2

            @SGaist

            it's an application in C use library gsl, hdf5, (fits at the end).
            I compile it (and it works with cygwin)

            If you realy want to see the project i use is here :
            https://github.com/christophe-pouzat/ENP2017

            the compilation line on cygwin an terminal linux :

            gcc -W -g -o code/roi code/roi.c -lgsl -lgslcblas -lhdf5 -lhdf5_hl -lm -std=gnu11
            

            and the execution is :

            ./code/roi -f Data_POMC.hdf5 -d stack -g 0.14 -v 290 -m > out/rss_stat 
            

            I think it's a problem of dll missing in this directory but i don't find them.

              You can use Dependency Walker to check what roi.exe needs to run

                @SGaist I have already used it but after download 45 *.dll "API...." (and i don't find all in https://fr.dll-files.com/) I'm desesperate.

                I see they are some *dll in 32bits and other in 64bits it's that ?
                How i resolved it ?

                Thanks again for your time :)

                dependency walker

                    The only files of real interest are the CYG**.dll the others are systems dll that you shouldn't need to do anything special for.
