Certain versions of binutils do not correctly support dynamic linking on
Solaris, which gives rise to symptoms similar to the ones you are seeing.  I
am pretty sure that binutils 2.13.2.1 works.  To find out whether the
version on your machine works, you can execute the following shell script:

#! /bin/sh
mkdir /tmp/t.$$ || exit 3
cd /tmp/t.$$ || exit 3
cat >main.c <<'EOF'
#include <stdio.h>
#include <dlfcn.h>
int main(void)
{
    void *handle, *sym;
    char *error;
    puts("calling dlopen");
    handle = dlopen("./dyn.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;
}
EOF
cat >dyn.c <<'EOF'
#include <stdio.h>
void sym(void)
{
    puts("in sym");
}
EOF
