 Well, we'll see if it work

nasun% cat a.c
#include <stdio.h>
#include <dlfcn.h>

int main(void)
{
    void *handle, *sym;
    char *error;

    puts("calling dlopen");
    handle = dlopen("./b.so", RTLD_NOW);
    if (!handle) {
        printf("%s\n", dlerror());
        return 1;
    }

    puts("calling dlsym");
    sym = dlsym(handle, "sym");
    if ((error = dlerror()) != 0) {
        printf("%s\n", error);
        return 1;
    }
    puts("calling sym");
    ((void (*)(void))sym)();
    puts("done");
    return 0;
}

nasun% 

nasun% cat b.c
#include <stdio.h>
void sym(void)
{
    puts("in sym");
}
nasun% 

 and compile it

  gcc -fPic -shared b.c -o b.so
  gcc a.c -ldl

  ./a.out
