system calls with cygwin
I'm having some difficulty with the use of system calls.
I cannot get any system calls to work on any other machine besides my development workstation.
All the machines that I have tried this on are running windows XP.
I thought it was a cygwin dll dependency but I literally copied the entire contents of the cygwing\bin directory into the into the directory with this program and nothing...
int main(int argc, char** argv)
error = system( "notepad.exe" );
printf( "ERROR: %d \n", error);
This program shows the system call having an error 127 every time on any other system but mine.
It seems that the original cygwin1.dll from my development machine makes the system call fail. If I install cygwin locally then use the dll from that install the system calls work.
Does cygwin build customs dlls for every installation?
Is it possible to build a statically linked version? That would eliminate the need for each target machine to possess the necessary dlls for the program to run.
1) Cygwin does no such thing.
2) It's not the system call that fails. Your program doesn't even launch.
3) You cannot compile cygwin programs statically. cygwin1.dll must be a dynamic library because of the way Cygwin works.
4) I suspect that you did something wrong in copying your cygwin1.dll to the other systems.
