Re: to add underscore or not to add underscore?


Hello Tim,

under linux-elf, DLSYM_ADDS_USCORE is not defined, which is CORRECT!

But is not correct to add underscore, because linux-elf has does not use
an extra underscore at all!  Here is untested peace of dynl-dl.c, with a
hopefully correct behavior:

#ifdef Linux
#define WE_DONT_NEED_UNDERSCORES_AT_ALL
#endif

#if (defined(DLSYM_ADDS_USCORE) || defined(WE_DONT_NEED_UNDERSCORES_AT_ALL))
    fptr = dlsym (handle, symb);
#else
    usymb = (char *) malloc (strlen (symb) + 2);
    *usymb = '_';
    strcpy (usymb + 1, symb);
    fptr = dlsym (handle, usymb);
    free (usymb);
#endif
