We gettextize under our package name, which we change to a more reasonable 'libctf'. Our internationalization support is mostly provided by ctf-intl.h, which is a copy of opcodes/opintl.h with the non-gettext_noop N_() expansion debracketed to avoid pedantic compiler warnings. The libctf error strings returned by ctf_errmsg are marked up for internationalization. (We also adjust binutils's Makefile a tiny bit to allow for the fact that libctf now uses functions from libintl.) binutils/ChangeLog 2020-08-27 Nick Alcock <nick.alcock@oracle.com> * Makefile.am (readelf_LDADD): Move $(LIBINTL) after $(LIBCTF_NOBFD). * Makefile.in: Regenerated. libctf/ChangeLog 2020-08-27 Nick Alcock <nick.alcock@oracle.com> * configure.ac: Adjust package name to simply 'libctf': arbitrarily declare this to be version 1.2.0. * Makefile.am (AM_CPPFLAGS): Add @INCINTL@. * Makefile.in: Regenerated. * configure: Regenerated. * ctf-intl.h: New file, lightly modified from opcodes/opintl.h. * ctf-impl.h: Include it. * ctf-error.r (_ctf_errlist_t): Mark strings as noop-translatable. (ctf_errmsg): Actually translate them.
