--- Comment #16 from Mike Frysinger <vapier at gentoo dot org> 2013-02-20 21:24:04 UTC --- i've verified that 2.23.51.0.8 works and 2.23.51.0.9 fails (the use case i posted involving webkit-gtk). both done using Gentoo ebuilds, but sans Gentoo patches (i.e. USE=vanilla). i can show the configure lines, but i don't think those are relevant -- it uses shared libs and a normal x86_64-pc-linux-gnu target. these tests were done using ld.bfd. ld.gold (both .8 and .9) is able to work. that said, in the webkit example, the code is apparently missing an -lrt. so maybe the .8 version is papering over the bug, and while .9 causes things to not link, it's not a bug with .9. ignoring, of course, that "invalid operation" message which is wrong either way. $ readelf -s Source/WebKit2/Platform/unix/Programs_WebKitPluginProcess-SharedMemoryUnix.o | grep shm_unlink 65: 0000000000000000 0 NOTYPE GLOBAL DEFAULT UND shm_unlink $ ./doit.sh ... /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.2/../../../../x86_64-pc-linux-gnu/bin/ld: Source/WebKit2/Platform/unix/Programs_WebKitPluginProcess-SharedMemoryUnix.o: undefined reference to symbol 'shm_unlink@@GLIBC_2.2.5' /usr/lib/gcc/x86_64-pc-linux-gnu/4.7.2/../../../../x86_64-pc-linux-gnu/bin/ld: note: 'shm_unlink@@GLIBC_2.2.5' is defined in DSO /lib64/librt.so.1 so try adding it to the linker command line /lib64/librt.so.1: could not read symbols: Invalid operation collect2: error: ld returned 1 exit status $ ./doit.sh -lrt <works> $ readelf -s Programs/.libs/WebKitPluginProcess | grep shm_unlink 716: 0000000000000000 0 FUNC GLOBAL DEFAULT UND shm_unlink@GLIBC_2.2.5 (9) 4389: 0000000000000000 0 FUNC GLOBAL DEFAULT UND shm_unlink@@GLIBC_2.2.5 -- Configure bugmail: http://sourceware.org/bugzilla/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug. _______________________________________________ bug-binutils mailing list bug-binutils@gnu.org https://lists.gnu.org/mailman/listinfo/bug-binutils
