Description Anthony Basile gentoo-dev

2016-02-04 09:55:10 UTC

While I hit the problem on a uclibc system, the issue is in numpy and I've opened a bug upstream.  The problem is that their commit c15f7747 did a bunch of code cleanups that moved #ifndef HAVE_CEXP@C@ ... #endif in numpy/core/src/npymath/npy_math_complex.c.src to cover a function definition that's called outside the #ifndef.  The problem is triggered on any systems where HAVE_CEXP@C@ is not defined (for some substituion of @C@).

While the upstream bug is being fixed, can we have an epatch_user added to dev-python/numpy-1.10.4 which is currently being stabilized so that it doesn't cause havoc with uclibc systems.  I have a temporary workaround.

Upstream looks like they have a huge backlog of bugs.  I'm pretty sure of my analysis, but the correct fix may not be easy.  I don't think upstream is going to get around to this or any bug any time soon.  Carrying epatch_user() forward might be wise for this package.

8 months later this is still not addressed upstream, at least the bug ticket is still open and a new uclibc-ng hardened system still breaks with numpy.

Can we include a patch for this to fix it until upstream has fixed the bug?

Fine with me, @blueness, will you add it? If possible, don't revbump the ebuild, as 99% of users aren't affected it by this.

This patch still applies to numpy-1.10.4 and it seems to compile the graph for git now.

In the mentioned issue upstream says its fixed. Can you confirm?
