From cbbfbfc54f3661f49a4b314eb187a09d7955226a Mon Sep 17 00:00:00 2001 From: Nitin A Kamble Date: Wed, 9 Mar 2011 09:26:13 +0000 Subject: gcc-runtime: fix LSB library checks for libstdc++.so.6 [YOCTO #795] When we run library check of LSB on qemux86 and qemuppc, we got some failures about 'libstdc++.so.6'. Test environment: Platform: Qemu-x86, Qemu-ppc lsb image: poky-image-lsb-qemux86-test.ext3(Feb 26th, auto-build server) Library check of LSB: 4.1.0-1 The error log: Did not find _ZNKSt5ctypeIcE8do_widenEPKcS2_Pc (GLIBCXX_3.4) in libstdc++.so.6 Unmangled symbol name: std::ctype::do_widen(char const*, char const*, char*) const ... found that some weak symbols ('W') change into local ('t') during link time and be stripped. According to compiling log, the option "-fvisibility-inlines-hidden" is used for gcc. And this option caused some weak symbols change into local. see http://bugzilla.pokylinux.org/show_bug.cgi?id=795 for more information on the bug.
