I can't compile my C- and C++-code

[Megrathund]

Hello,

when i will compile my C-code or C++-code it's come an error is popped up:
"'gcc' could not be spawned. Is it installed and on your path? If so please open an issue on the package spawning the process."

I have the "gpp-compiler"-package installed by "kriscross07".

my code:
#include <stdio.h>

int main() {

printf("Hello World!");

return 0;
}

Can you help me, please?
Thank you
