Well, I never tried the latter, but it appears they are not on your system ;-)
Now, I don't know where exactly these functions are declared (in which unit, that is), but for debugging purposes, just add Function dlopen(filename: PChar; flags: cint): Pointer; cdecl; external; Function dlclose(handle: Pointer): cint; cdecl; external; Function dlsym(handle: Pointer; Name: PChar): Pointer; cdecl; external; Function dlerror: PChar; cdecl; external; Somewhere in your code before you call them. -- Ewald _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
