Fons: i tried with existing path.
Library path is valid - i checked it with ls (doing it for ladspa dir before
to get libraries list).
Code - includes are omited, line with main() declaration is numbered
30: int main (int argc, char ** argv)
{
        //LADSPAPluginSearch(describePluginLibrary);
        char plugpath [] = "/usr/lib/ladspa/tap_echo.so";
        void * pvPluginHandle = dlopen(plugpath, RTLD_NOW | RTLD_LOCAL);
        if (pvPluginHandle) dlclose (pvPluginHandle);
        else printf ("dlopen failed: %s\n", plugpath);
        return 0;
}
hermann: thanks, will look

 You should provide some code, it's hard to help you without seeing what
 your program really does.
