Please provide more information, your assessment it's the "same" bug might not be true. $ uname -a Linux m246 2.6.18-194.26.1.el5 #1 SMP Tue Nov 9 12:54:40 EST 2010 i686 i686 i386 GNU/Linux $ cat /etc/*-release CentOS release 5.4 (Final) When building on $ uname -a Linux jansmb 2.6.9-103.ELsmp #1 SMP Fri Dec 9 04:31:51 EST 2011 i686 i686 i386 GNU/Linux $ cat /etc/*-release CentOS release 4.9 (Final) it's all right When I'm trying link libstdc++.a statically to my .so I see messages like: "undefined versioned symbol name std::defer_lock@@GLIBCPP_3...." $ nm libstdc++.a | grep @ shows me that archive contains versioned symbols. Do you need the entire list? Note: undocumented configure option --disable-symvers helps but I think building with default parameters must work properly The exact description: $ g++ -o formats/alcatel_alm9_decoder.fmt -shared -Llib -static-libgcc -O3 -Wl,-s -Wl,--no-undefined src/alcatel_alm9_decoder.o formats.a decoder.a -ljanuary_tools -ljanuary /usr/bin/ld: formats/alcatel_alm9_decoder.fmt: undefined versioned symbol name _ZSt10adopt_lock@@GLIBCXX_3.4.11 /usr/bin/ld: failed to set dynamic section sizes: Bad value collect2: error: ld returned 1 exit status $ nm lib/libstdc++.a | grep adopt 00000000 B _ZN9__gnu_cxx10adopt_lockE 00000000 B _ZSt10adopt_lock@@GLIBCXX_3.4.11 (In reply to comment #4) > Note: undocumented configure option --disable-symvers helps but I think > building with default parameters must work properly It's not undocumented http://gcc.gnu.org/onlinedocs/libstdc++/manual/configure.html (In reply to comment #6) > (In reply to comment #4) > > Note: undocumented configure option --disable-symvers helps but I think > > building with default parameters must work properly > > It's not undocumented > http://gcc.gnu.org/onlinedocs/libstdc++/manual/configure.html Ok. But still. It must not be a mandatory option to build correct static lib (In reply to comment #7) > isn't this PR 52689 ? Probably it is. When 4.7.1 will be released? yesterday http://gcc.gnu.org/gcc-4.7/ marking as dup, please reopen if 4.7.1 doesn't fix it *** This bug has been marked as a duplicate of bug 52689 *** |
