Just a short,terse list: Don't use nondefault optimization. There is something going on with the code that breaks, runtime, when compiled (which works fine per se) with higher optimization levels. IPA is a real difficulty. Remember to set OBJECT_MODE=64 in OS env! upgrading m4/autoconf and then configure seems to really help. (m4 needs __STDC__ to get around "va_list" compilation error) setting LIBPATH is quite helpful. ---------------------------(end of broadcast)--------------------------- TIP 7: don't forget to increase your free space map settings
