Hi all,
I compiled a C program with a system() call in a mingw64 shell. And it
works there. However I want to ditribute it without the complete msys
environment, therefore, it must work in a Win10 cmd shell.
When I execute the program (together with msys-2.0.dll) in a cmd shell
it only works when the program resides in the msys installation
directory. If I move these two files to another directory (i.e. bin) it
fails.
Here is an simple example:
vvvvvvvvvvvvvvvvvvvv
systest.c
#include <stdlib.h>
#include <stdio.h>
int main( void )
{
FILE *fp;
printf("+++ system NULL: %d\n", system( NULL ));
printf("+++ system echo: %d\n", system( "echo hello" ));
}
^^^^^^^^^^^^^^^^^^^^^
compiled with: gcc -o systest systest.c
If I execute it in a cmd shell in my mingw64 home directory the output is
+++ system NULL: 1
hello
+++ system echo: 0
Moved to the other directory I get the following output:
+++ system NULL: 1
+++ system echo: 127
Can anyone tell me how to make such a program working within a cmd shell
in other locations than the mingw64 home directory?
Thanks.
Flo
PS: If I replace echo with a nonexisting command, I get an error message
instead of 'hello' in the first place but again nothing in the second run.
