Hi,
args[0] must contain the binary.
And the last values of args and anvp must be NULL, but maybe it works
with 0 too.
So try this:
int main( int argc, const char* argv[] )
{
char *args[2] = { "/home/michael/MyGtkApp", "testarg", NULL };
char *envp[1] = { NULL };
execve("/home/michael/MyGtkApp",args,envp);
}
