Bug 147473 – dev-python/numpy fails to compile with as-needed

• Product: Gentoo Linux
• Status: RESOLVED UPSTREAM

[Description Sébastien Fabbro (RETIRED) 2006-09-13 09:53:53 UTC]

I put numpy-1.0_beta5 in the http://gentooscience.org overlay (only change is the homepage). But I can't make it work with as-needed. Anyone here could help me on this? This version is needed for >=matplotlib-0.87.5 and >=scipy-0.5.1

The distutils in numpy/scipy is very customized and setting any LDFLAGS at all breaks it because it overrides all the internal linker flags instead of adding to them. This is known to upstream, so I've just forced off LDFLAGS for now. Feel free to reopen when you notice upstream's fixed this.
