Hi there!
I am trying to force a gcc4.x compiler to use the libstdc++5 per default.
This is needed because some "binary-only" Shared Libaries supplied by a
3rd party vendor uses libstdc++5.
libstdc++5 is used by gcc-3.3 compilers - but unfortunately a gcc-4x is
needed to compile the project.
I spent some days of work to force a gcc-4x to use libstdc++5 per
default. But I did not come closer to a solution.
Do you have any ideas?
It is not possible (as you have discovered). Versions of libstdc++ are
tightly tied to compiler versions. You will *have* to modify your code
to compile under gcc-3.3, probably by not using the features of gcc-4x
your project now uses -- you will have to hack around the missing
features.
Either that or talk to the 3rd party vendor and try to get them to
re-build their libraries using gcc-4x & libstdc++6.
Another possiblity is to build a gcc-3.3/libstdc++5 wrapper application
that is run as a separate process from your main gcc-4x project and pass
data back and forth with sockets or pipes.
That was my concern.
Regarding the gcc documentation gcc-3.3 uses abi version 1, and gcc-4.x
uses abi version 2.
The gcc option -fabi-version=1 sounds like it should be possible to
force the usage of the older abi.
So I have recompiled the whole project with -fabi-version=1. But that
seems to have no effect.
What is -fabi-version used for?
