From: "Alexey I. Froloff" <raorn@altlinux.org> To: ALT Devel discussion list <devel@lists.altlinux.org> Subject: [devel] Q: Переименование символов и сохранение ABI Date: Sun, 6 Jun 2010 11:09:29 +0400 Message-ID: <20100606070929.GC22655@altlinux.org> (raw) [-- Attachment #1: Type: text/plain, Size: 952 bytes --] Апстрим librep переименовал несколько символов не меняя SONAME. Хочется сохранить ABI. Раньше оно выглядело так: $ nm -D /usr/lib/librep.so.9.5.0 | grep file_uid 000168e0 T Ffile_uid_p 000547c8 B Qfile_uid_p Собсно, убрали "_p". Код раскрывается в следующее: repv Qfile_uid; repv Ffile_uid(repv arg) { ... } Делаю alias'ы: extern __typeof__ (Ffile_uid) Ffile_uid_p __attribute__ ((alias ("Ffile_uid"))); extern __typeof__ (Qfile_uid) Qfile_uid_p __attribute__ ((alias ("Qfile_uid"))); С функцией такой трюк проходит, а с common symbol нет: {standard input}:6039: Error: `Qfile_uid_p' can't be equated to common symbol 'Qfile_uid' У этой библиотеки полтора пользователя, но хотелось бы знать как в принципе решать подобные проблемы. P.S. Символ Qfile_uid в выводе rpmsodiff(1) не фигурирует. P.P.S. Погрепал DSOHOWTO, ответа не нашёл. -- Regards, -- Sir Raorn. --- http://thousandsofhate.blogspot.com/ [-- Attachment #2: Digital signature --] [-- Type: application/pgp-signature, Size: 198 bytes --]
