Python3 and Numpy

Python3 and Numpy

[Benoit Rapidel]

Hi,

I want to install NumPy with Python3 supporton a Beaglebone Black. Unfortunately, I 
couldn't find any information or a recipe. Anyone has ever tried, success, failed ?

Regards,

There is a recipe for numpy in oe-core, but it's not particularly up to 
date, and doesn't have python3 support. You are welcome to update it and 
send patches :)

I found one in meta. How do I update it ? I'm using poky jethro.
Should a create a new one named python3-numpy or the same recipe should handle both
python versions ?

@Alex, sorry for that, reposting in the mailing list.

 From what I can see, the standard approach is to create a separate 
recipe for python3.

If you want to tweak, it's best to base your work on poky master.

Ok, thanks

Numpy start to except ld can't find npymath and npysort. I checked with devshell, 
there is libnpymath.a and libnpysort.a within build/temp.linux-x86_64-3.4, which is 
used by ld to find libs. Do you have any clues ?

I'm trying to compile numpy 1.9.2 with python3.

Thanks in advance

Re: Python3 and Numpy

Hello,

I'm still trying to get python3-numpy to compile. I have been inspecting log file for 
quite a while. One lead I got is that gcc have -L=/usr/lib in its arguments.
I diff log.do_compile from python3-numpy and log.do_compile from python-numpy.
I see no reference to /usr/lib in python-numpy log. How can I remove this -L=/usr/lib 
from arguments to try compiling without searching in this dir ?

Here is the recipe failing:

https://github.com/exmachina-dev/meta-exm-core/blob/master/recipes-python/python3-numpy/python3-numpy_1.10.1.bb

It's mainly taken from python-numpy_1.10.1.bb found in openembedded-core/meta. I 
renamed all refs of python to point to python3 and I fixed a bug. Config files 
couldn't be copied due to multiple paths after `grep src` (py and py3).

And here the full log from log.do_compile (-L=/usr/lib is found at L2143, L2193, 
L4335 and L4385):

http://sprunge.us/INYI?log

I also found that the setup.py tried to build Fortran code with /usr/bin/gfortran 
(from host). As python-numpy did not find gfortran, I temporarily uninstalled 
gfortran from host (L97 now don't find gfortran).

I'm really stuck with this recipe. Any help from you guys is much appreciated.

Many thanks,
B
