Re: [Tinycc-devel] #pragma comment(lib,...) patch

[Steven G. Messervey]

Sorry to keep flip-flopping!

My original test case for libtcc used tcc_add_file(...) to execute the 
compilation.
My target application uses tcc_compile_string(...).
When using compile_string, the #pragma has no effect, an tcc complains about 
unknown symbols.

If it's of any help, tcc -run won't link static libs, either:

/* hello.c */
#include <stdio.h>
void hello(void) {
  printf("Hello\n");
}
/* end hello .c */

$> gcc -c hello.c
$> ar rcs libhello.a hello.o

/* dumb.c */
extern void hello(void);
int main(int argc, char **argv) {
  hello();
  return 0;
/* end dumb.c */

tcc -vv -L. -lhello -run dumb.c
tcc version 0.9.26 (i386, Linux)

tcc: error: undefined symbol 'hello' 

As you can see at the top of the output, './libhello.a' is found, and 
recognized as a static library, but tcc cannot link it in.

Have we uncovered a can of worms?

Thanks,
