Re: [Tinycc-devel] Compilation error while including LAPACKE

[Domingo Alvarez Duarte]

After your last message I've tried defining "_Complex" to empty and for 
the simple test it compiled, probably if you are not using complex this 
trick could work:

=====

#include <stdio.h>
#define _Complex  //make it e noop
#include <complex.h>

int main() {
  printf("Hello World!\n");
  return 0;
}

====

Output:

====

../tcc  cmath.c
>Exit code: 0
./a.out
>./a.out
Hello World!
>Exit code: 0

====
