Subject: Relation between gcc version and libstdc++ version
Date: Tue, 30 Aug 2022 16:47:14 +0200	[thread overview]
Message-ID: <4161b707473552ce74c41c8867c2cc6d77ff4e05.camel@gmail.com> (raw)

Hello list!

I was trying to build a cross-compilation toolchain for a specific
target using a newer GCC version, than the one that the binaries were
build on the target.

The C part seems to work well, but the C++ part doesn't.  It seems that
the G++ ships it's own libstdc++ include headers.  If this libstdc++ is
newer than the one one the target, I get undefined references (because
there are some newer implementation details and things like that).  Is
it possible to tell G++/GCC to use the libstdc++.so from the target and
also to use the C++ headers (like iostream) from the target?
If not, is there any reason this is hard-coded?

With clang it looks like you can specify "any" libstdc++ version you
want, although I haven't tested it yet.

Kind regards,
Anton
