Given these functions have been removed in POSIX 2008, they should probably be avoided. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-glibc-requ...@lists.debian.org with a subject of unsubscribe.

You mentionned rebuilding Qt 4. Does it happen with binaries you have rebuilt yourself, or at least that link to libraries you have rebuilt yourself? If yes, make sure you don't have binutils-gold installed, as it is currently broken with eglibc 2.11 (see bug#585051).

I forgot to mention: after downgrading eglibc I wanted to start Qt apps compiled with eglibs 2.11 without recompile but the system complained about different sizes of strlen() and related functions (sorry, I can't remember the exact message). Does this mean that 2.11 isn't binary compatible? Ok, this means that you are compiling with binutils-gold, which produce broken binaries, hence this message. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-glibc-requ...@lists.debian.org with a subject of unsubscribe.

That's wrong, it does contain some optimized functions (otherwise you won't have seen this bug). Here is the list: - strcasestr - strcpy - rawmemchr - strncmp - strrchr - stpncpy - strncpy - strpbrk - strspn - stpncpy - strlen - strstr - strcspn - strchr - rindex - stpcpy - strcasestr - rawmemchr - strcmp - stpcpy Moreover we can also backport the optimized functions that have been added in 2.12, but the current goal is to move 2.11 to squeeze, so it will be for later.

No, we can't break the ABI, so they will stay (almost) forever. But it means that it probably won't be supported by new architectures or new operating systems and become less and less portable. That's why they should be avoided. -- Aurelien Jarno GPG: 1024D/F1BCDB73 aurel...@aurel32.net http://www.aurel32.net -- To UNSUBSCRIBE, email to debian-glibc-requ...@lists.debian.org with a subject of unsubscribe.
