Re: [Tinycc-devel] Is static linking functional?

Hi Wendell P,

The original problem here is not the same as you previous supposed to, and 
would not be solved in that way. You need to explore why it can't find the 
library. It doesn't mean the lib has a wrong format.

tcc_add_library() will be run. 

---------
LIBTCCAPI int tcc_add_library(TCCState *s, const char *libraryname)
{
#ifdef TCC_TARGET_PE
    const char *libs[] = { "%s/%s.def", "%s/lib%s.def", "%s/%s.dll", 
"%s/lib%s.dll", "%s/lib%s.a", "%s/%s.c", NULL };
    const char **pp = s->static_link ? libs + 4 : libs;
    const char *filename;
#else
    const char *libs[] = { "%s/lib%s.so", "%s/lib%s.a", NULL };
    const char **pp = s->static_link ? libs + 1 : libs;
#endif
......
}
---------

And, specified by switch "-static":

---------
PUB_FUNC int tcc_parse_args(TCCState *s, int argc, char **argv)
{
......
        case TCC_OPTION_static:
            s->static_link = 1;
......
}
---------

Now you see? I think this is grischka meant.
