AIX uses LIBPATH, > not LD_LIBRARY_PATH. It doesn't create libintl.a with a libintl.so.8 inside of it. The libintl.a contains a bunch of objects, as I'd expect of a static library: --8<---------------cut here---------------start------------->8--- -bash-5.1$ ar -t gettext/intl/.libs/libintl.a | grep libintl -bash-5.1$ ar -t gettext/intl/.libs/libintl.a bindtextdom.o dcgettext.o ... --8<---------------cut here---------------end--------------->8--- > Also, for me, the out of tree path was > > gettext/gettext-runtime/intl/.libs > > Is your search path missing a level? No, the above is generated by the GCC build system and builds gettext-runtime directly (per Brunos recommendation a while ago) as it is replacing intl/ of similar functionality. I'm currently building GCC with libintl with the threads hack you mentioned applied (as I got undefined references to the pthread functions you discovered). I suspect that, bar this issue (which, IIUC, Bruno will fix in a new release?) the patch above will fix the issues you've encountered on AIX (note that if you want to use gettext in-tree, you'd still have to fetch gettext into the tree). Maybe we should provide a download-prerequisite-y script that skips everything but GNU gettext, to retain same behavior? Have a lovely day. -- Arsen Arsenović
