Bug 547788 – sys-devel/gcc-5.1: new default ABI: cxx11 incompatible with GCC-4.9

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description LE GARREC Vincent 2015-04-26 10:31:06 UTC]

From forum t1015870:

I just install the new version of GCC 5.1 and now I have some errors "undefined reference to". After reading https://gcc.gnu.org/gcc-5/changes.html I saw that "The C++ runtime library (libstdc++) uses a new ABI by default"

Here a kind of error message I have :
/home/legarrec/info/portage/dev-cpp/gtkmm-3.16.0/work/gtkmm-3.16.0/tools/extra_defs_gen/generate_defs_gdk.cc:49: undefined reference to `get_defs[abi:cxx11](unsigned long, bool (*)(unsigned long))'	

so it's write that the problem is "[abi:cxx11]"

An other example :

../lib/.libs/libeurocodes.so: undefined reference to `Gtk::Builder::create_from_resource(std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&)'
/usr/lib/gcc/x86_64-pc-linux-gnu/5.1.0/../../../../lib64/libgtkmm-3.0.so: undefined reference to `Glib::ustring::ustring(std::string const&)'	

Here, there is no reference to the new ABI for Glib::ustring::ustring but for create_from_resource there's "std::__cxx11". My program compiles fine with GCC 4.9 but not with GCC 5.1.

The problem disappears by emerging glibmm then gtkmm with GCC 5.1. But then, with GCC 4.9, I have in my program :

../lib/.libs/libeurocodes.so: undefined reference to `Gtk::Builder::create_from_resource(std::string const&)'
../lib/.libs/libeurocodes.so: undefined reference to `Glib::ustring::ustring(std::string const&)'	


According to https://wiki.gentoo.org/wiki/Upgrading_GCC, running "emerge -eav system" and "emerge -eav world" is old school. But do you think that with this new change of the default ABI, I should emerge the whole world ? Actually, I didn't do it but I can easily. But my main problem is that GCC 5.1 is not compatible with GCC 4.9.

Reproducible: Always

There are some critical bugs that will most likely prevent you from doing that. For instance, neither Xorg, nor Python 3 are properly working at the moment.

Have you tried to use -std=gnu++98 ?

You can either selectively upgrade your packages, or wait until everything has stabilized with GCC 5.1.

[Comment 2 Ryan Hill (RETIRED) 2015-04-27 01:53:03 UTC]

Yes you need to rebuild world, this is a major version bump.  No you should not be using gcc-5.1 at this point unless you know what you're doing.

[Comment 3 SpanKY 2015-08-21 21:24:37 UTC]

revdep-rebuild support to try and automate is tracked by bug 550432
