Problem with petsc4py? #52

Closed quang-ha closed 8 years ago

quang-ha commented 8 years ago

Was helping my friend installing fenics using conda packages. When we came across petsc4py build, the following error comes up:

fatal error: numpy/arrayobject.h: No such file or directory
 #include "numpy/arrayobject.h"

Apparently for some reasons, conda does not have numpy header files in include/python2.7/ but it is allocated in lib/python2.7/site-packages/numpy/core/include/numpy instead...

Could well be a bug, but now as I was trying to install dolfin using these recipes on a new environment, this happens as well...

Hi

Which platform is this? I have not seen this on my Ubuntu 15.04. I am starting a fresh anaconda, installing gcc and cmake and then dolfin dependencies with no problems. Have you tried to remove the 1.9 dependence of numpy from meta.yaml? The newest numpy in anaconda is 1.10...

quang-ha commented 8 years ago

My fresh numpy on conda is 1.10, so... still manage to flick through dolfin install without petsc4py anyway...

Platform wise, Ubuntu 14.04 LT3

mikaem commented 8 years ago

Ok, but are you removing "==1.9" from "numpy ==1.9" from meta.yaml when building petsc4py?

quang-ha commented 8 years ago

I changed it to >=1.9 and it never asked numpy to downgrade.

quang-ha commented 8 years ago

Seems like the instruction to install with conda on the webpage fenicsproject.org would need to be updated as well.. I don't recall seeing boost here but that's a separate matter...

mikaem commented 8 years ago

Conda is a living breathing environment bound to fail from time to time. What's the issue with boost?

quang-ha commented 8 years ago

Just to point out that here the instruction still say boost :) http://fenicsproject.org/download/installation_using_conda.html#installation-using-conda while it should not anymore

mikaem commented 8 years ago

Ah, sure, boost from anaconda is ok now, no need to build it. But these things are changing rapidly. It was only a few months ago that anaconda swig was version 2 and too small to build dolfin...

Thanks a lot for taking care of this issue @mikaem, I didn't even have time to answer :)
