From: Jonathan Liu Date: Sun, 21 Jul 2013 10:07:42 +0000 (+1000) Subject: gcc-4.8: fix compiling GCC when /usr/lib/libstdc++.so is present X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=dd8865aac9b0cb86f16897e59f6fd77a2c6cb000;p=thirdparty%2Fopenembedded%2Fopenembedded-core-contrib.git gcc-4.8: fix compiling GCC when /usr/lib/libstdc++.so is present libtool is picking up libstdc++.so from /usr/lib when trying to link libasan due to libstdc++.la containing libdir="/usr/lib". If compiling for x86 and the host has 64-bit /usr/lib/libstdc++.so, the compilation fails linking libasan with: /usr/lib/libstdc++.so: could not read symbols: File in wrong format To resolve this, patch libtool to look for the library in the path the .la is contained in rather than use the libdir which usually points to a host path.
