Re: [sage-devel] [abi:cxx11] in givaro prevents linking to system givaro on Fedora 32
This is now re-surfacing in Gentoo. I see sagelib using
Givaro::Integer::operator std::__cxx11::basic_string, std::allocator >[abi:cxx11]() const
but the system Givaro only providing
Givaro::Integer::operator std::__cxx11::basic_string, std::allocator >() const

IMHO we just shouldn't use the system version then, but building Sage
with -D_GLIBCXX_USE_CXX11_ABI=0 should allow you to link with old-style
abi
libraries.
The default value of _GLIBCXX_USE_CXX11_ABI can be changed by the
distro, which is probably what accounts for the differences seen in this
thread.

as Francois reports above, on Gentoo he has libgivaro providing two
interfaces, one with abi:c++11, and one without.
Apparently, done by by setting a gcc option, as mentioned by Steven.

Re: [sage-devel] [abi:cxx11] in givaro prevents linking to system givaro on Fedora 32
"Dual" refers to libstdc++ here, i.e. you only have one standard library
supporting both abi's.
Other libraries generally are only one or the other, this is what is
controlled by the -D_GLIBCXX_USE_CXX11_ABI; Theoretically you could make
your own dual-abi library but you'd have to plaster
__attribute__((abi_tag("cxx11"))) everywhere, so hell no.
What I'm saying is: if you provide the same value for
-D_GLIBCXX_USE_CXX11_ABI as what was used for the system givaro then you
should be able to link them together.

Re: [sage-devel] [abi:cxx11] in givaro prevents linking to system givaro on Fedora 32
This is c++11 dual abi, see https://gcc.gnu.org/onlinedocs/libstdc++/manual/using_dual_abi.html IMHO we just shouldn't use the system version then, but building Sage with -D_GLIBCXX_USE_CXX11_ABI=0 should allow you to link with old-style abi libraries. The default value of _GLIBCXX_USE_CXX11_ABI can be changed by the distro, which is probably what accounts for the differences seen in this thread.
