Re: [libdnet-devel] python module build error on Fedora 8

[Jon O. <jo...@ob...>]

Zheng,

GCC 3.something deprecated lvalue casts as warnings and recent versions
now treat them as an error.  Try regenerating the dnet.c file from
dnet.pyx with a current version of pyrex or cython.

Regards,
Jon Oberheide
