QProcess : "Process failed to start : No such file or directory"

[Julie]

@SGaist Thank you It seems to be that !
I continue and i tell you if it's always ok.

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 :

What kind of application is roi.exe ?

[Julie]

@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.

[SGaist]

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

[Julie]

@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 :)

[Julie]

new view :

[SGaist]

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.

[Julie]

@SGaist ok, thanks!
And use this dll in c:cygwin64.
Why is'nt good ?
(I put new pictur in my last post)

I try to make same reserche with my c++ project and i see this (it's only a part of result):

my project is in x86.
Do i change all my dll in x86 ?
