Hi,
I am trying to update my Mandriva package of sagemath to 4.3.1, but
I am having serious issues with givaro/linbox.
For some reason, only --enable-sage appears to break linbox, but,
for some reason, with gcc 4.4.3 (the one in
Mandriva cooker), it will not build liblinboxsage.so.
I tried:
o linbox 1.1.6 + givaro 3.2.13, matching sagemath spkgs
o linbox 1.1.6 + givaro 3.3.1
o linbox 1.1.7 + givaro 3.3.1
o todays linbox svn + givaro 3.3.1
sagemath interface to givaro should work correctly with a small patch
for the "minor" changes, e.g. s/amxy/maxpy/,
but no matter what, I am getting several missing symbols.
I am somewhat lost as I am not experienced with C++ templates, but
after making several changes last night
to get linbox 1.1.6 to work with givaro 3.3.1, I ended up with the
same errors I get with linbox 1.1.7 and svn linbox
plus givaro 3.3.1. I stopped last night when I needed:

Sorry for the long email.
Any ideias of how to get this to work, with any linbox version,
preferably givaro 3.3.1 as someone already
updated mandriva package..., and gcc 4.4.3 is welcome.
Thanks,
Paulo
