hello again.
(I miss clicked and sent before finishing the last mail)
So.. the tag
experiment/g++4.4compilable-lw
<https://github.com/pgRouting/pgrouting/releases/tag/experiment%2Fg%2B%2B4.4compilable-lw;
Is thought for centos6, has pgRouting 2.1 compilable with g++4.4 and it can
be used with postgres9.6 and has some wrappers to use better code where
possible.
As a reminder I don't expect problems for CENTOS 7 and pgRouting version
2.3.1.
Regards
Vicky
