I think I have to clarify my question a bit:
I have a program which is a mix of c++ & fortran code. Fortran part is
compiled with lang/ifc, so to link it I use something like
ifort -o prog for_lib.a cpp_lib.a -l.... -lstdc++
Now I have to use one more library, which is not (yet) compatible with
gcc 3.4 and up. If it matters -- this library is luabind (luabind.sf.net)
and I don't really know of any alternatives to it (except tolua/tolua++
which are even more problematic). So to link my code now I have to rebuild
a bunch of other packages using gcc33 and link it like that:
ifort -o prog ...... /usr/local/lib/gcc-lib/......./libstdc++.a
Doing it this way is quite messy, provided that I have to build/use this
code time to time on linux machines where it should be linked in absolutely
different way.
So the question is if it possible to convince lang/gcc33 to produce code
binary compatible with system-wide gcc 3.4?
