[Tinycc-devel] Unable to find include directories by tcc on Catalina

[Peng Yu]

Hi,

tcc can not find the include directory correctly. It seems that the
include directories are hardcoded in the tcc binary. Should they be
put in a configuration file?

How to fix this problem? Thanks.

$ cat main.c
#include <stdio.h>

int main() {
        puts("Hello World!");
        return 0;
}
$ tcc -run main.c
main.c:2: error: include file 'stdio.h' not found
$ brew info tcc
