[lsst-dm-stack-users] Fwd: Troubles building Winter2013Beta on Ubuntu 11.04

[Jim Bosch]

I'm afraid the root problem here is a known bug in gcc 4.5 that makes it incompatible with the ndarray package (we have to #ifdef out parts of ndarray to get it to work at all with gcc 4.5, and those parts are in use by afw here).  Both gcc 4.4 and gcc 4.6 are known to work.  If it's possible to try one of those compilers on your system (or clang), I would recommend that.

HTH!

Jim

While this is intended to make linking more robust, this currently breaks the LSST build. To undo the effects of these changes, add the following environment variables
