Hello, you were right, I didn't give enough details (it was 3:00 am for me
Anyway I resolved my problem :
I wanted to launch something like "C:\Program
So I tried to translate the path of the exe in cygwin paths, or the path of
the argument, or both, but nothing seemed to work. Finally I understood!!!
The program needs a DOS path, even if it is launched through cygwin. And ,
Here is the tricky thing, the argument is parsed by cygwin, so :
c:\WINNT\Temp\temp_0123456.txt" does not work
But "/cygdrive/c/Program\ Files/Pilot_Install_4.0
The "\\" are interpreted by Cygwin as "\" and are needed for Cygwin to pass
an "understandable" path to windows.
And trickier, I use several strings in my program to build this command
line, and so, there is a second interpretation of the string. So the string
I must use to build this command line is :
Anyway thanks for help.
