On Mon, 12 Dec 2005, Nuno Lopes stipulated:
Update: I've tried to compile some sample sources, but linking has
failed with:
Yeah, linking two libraries using incompatible versions of libstdc++
will be tricky, requiring linking against *both* copies using -Bgroup.
(It's best to experiment using little testbed shared libraries exporting
symbols of the same name, printing out different things from each shared
library, until you grasp how -Bgroup works. It can be counterintuitive.)
But I supposed that compiling it with proper -fabi-version would do the
trick..
If you do that *and* point the libstdc++.so symlink to libstdc++.so.5, you
should be OK. (I didn't think of that. Oops.)
(...)
If you repoint the .so (no need to do anything with the .so.[56] files
themselves) and use the right -fabi-version, everything should just
work, I hope. (I didn't think of that, even though in hindsight it's
bloody obvious. Ah well. It's *much* more likely to work than messing
with -Bgroup.)
Hi again,
Many thanks for your help. I've been able to build a couple of programs and
link them. (although I've not tested to run them yet, only tomorrow I'll
have access to a mips machine).
However not all programs are linking correctly. I've attached the errors
I've got when building a Sony's example
(http://mega.ist.utl.pt/~ncpl/openr_gcc4.txt).
I've built gcc 4.0.2 and replaced the
mipsel-linux/lib/libstdc++.a/libstdc++.la/libsupc++.a/libsupc++.la with the
ones generated by gcc 3.3.6.
What do I need to do now to make it link correctly?
Thanks in advance,
Nuno
