Description Guillaume Horel 2007-09-26 00:43:43 UTC

Arpack-96 compiles fine with gcc-4.2.0, but linking against it doesn't work.
For instance, freemat 3.4 fails to see arpack during the configure part.
Checking config.log reveals that the test fails with:
/usr/lib/gcc/i686-pc-linux-gnu/4.2.0/../../../libarpack.so: undefined reference to `etime_'

Reproducible: Always

Steps to Reproduce:
1.emerge freemat with arpack support
2.
3.

Found a patch on http://www.ann.jussieu.fr/pipermail/freefempp/2007/000394.html which fixes the issue for me.

Hi Guillaume,

Thanks much for the note and the patch! I just
fixed this in portage cvs; please re-sync in an hour
or so and re-emerge arpack and you should have it.

Best,
Markus
