Strange undefined reference link errors for boost_regex

[shzhang@…]

Hi,

When I link boost library to my application, it will report lots of link errors, unless i have already added libboost_regex library. I am working on Centos6.7, gcc-4.8.4, 64bit.

Here is the errors: MakeFiles/myapp.dir/source/cornerAnal.cc.o: In function `CustomRandomMgr::nameMatchPattern(stlp_std::basic_string<char, stlp_std::char_traits<char>, stlp_std::allocator<char> >

What do you mean by "already added libboost_regex library"?

The linker command -lboost_regex should appear *after* all of the object files which use Boost.Regex.

Nope, that's a different issue - that issue is caused by compiling against headers from one version and linking to a library from a different version. That's not supported and never has been, it's just that the issue is caught now. It's also not our problem but a packaging issue somewhere downstream...

A packaging issue downstream? For Version 1.60, 1.61 and 1.62 ? Is there any way to find out whats inside /usr/lib/i386-linux-gnu/libboost_regex.so.1.60.0 ?

[John Maddock]

Sorry I was a bit short and harsh:

• Boost has never supported binary compatibility between releases, if you compile against one versions headers and link to another versions .so file, bad stuff will happen somewhere down the road.
• Recent Boost.Regex releases have enforced this by mangling their namespace with the Boost version number - the only difference from previous releases is that now you're prevented from shooting yourself in the foot quite so often ;)
• If you just specify -lboost_regex on the command line, you will presumably link against whatever version was installed by the official system package. Use the "file" command to discover where libboost_regex.so points.
• If you manually install a later version, or use a package someone has prepared, then there are a whole host of possible build options that are outside our control - in particular they may install the binaries in a location not searched by default (such as /usr/local/lib), but you will need to consult the package builders own documentation on this. You may also need to link against a specific version if the libboost_regex symlink has not been over-written.
• If in doubt you can see what symbols are exported from a library with "nm -gC libraryname.so"

Hi,

This problem is resolved.

After I use "nm -gC libboost_regex.so" command to check my library, I find the 0000000000051370 W boost::re_detail_106000::perl_matcher<boost::re_detail_106000::mapfile_iterator, stl::allocator<boost::sub_match<boost::re_detail_106000::mapfile_iterator> >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)

And my link error is: error: undefined reference to 'boost::re_detail_106000::perl_matcher<char const*, stlp_std::allocator<boost::sub_match<char const*> >, boost::regex_traits<char, boost::cpp_regex_traits<char> > >::construct_init(boost::basic_regex<char, boost::regex_traits<char, boost::cpp_regex_traits<char> > > const&, boost::regex_constants::_match_flags)'

So it is caused by my application use stlport library. After I re-compile boost library with "stdlib=stlport" option and specified "using stlport" in project-config.jam file, the link process is OK now.

Thanks very much for your help.

Thanks, Shaohua
