Description Dmitry Marakasov 2009-05-22 16:30:04 UTC 
eigen2 uses aligned malloc routine (ei_aligned_malloc), which currently relies on posix_memalign. The latter is not available on 6.x, so dependent ports may fail to build (example is upcoming science/avogadro, ports/134710).

FreeBSD malloc, however, is guaranteed to return 16-byte aligned pointers, so it may safely br used instead of posix_memalign, on 6.x as well.

The patch mekes EIGEN_MALLOC_ALREADY_ALIGNED defined on FreeBSD, so malloc is used.

Added file(s):
- files/patch-Eigen-src-Core-util-Memory.h

Port maintainer (kde@FreeBSD.org) is cc'd.
