Hi all, I've just tried to set up a Python 3 test environment for me to begin porting PyCUDA and PyOpenCL to Python 3, but numpy installation managed to foil my. I'm on Debian, and I believe that Debian purposefully compiles ATLAS without pthreads support. Whenever I build numpy 1.5, I encounter this error:
Python 3.1.2 (release31-maint, Jul 8 2010, 09:18:08)
[GCC 4.4.4] on linux2
Type "help", "copyright", "credits" or "license" for more information.

ImportError:
/home/andreas/src3/lib/python3.1/site-packages/numpy/linalg/lapack_lite.so:
undefined symbol: ATL_dptsyrk
I gather that "pt" in the symbol name means that this is a
pthreads-accelerated version of dsyrk. How do I convey to numpy that I
don't have (nor want) Pthreads-accelerated ATLAS bits? Failing that, how
do I tell it to just not use ATLAS?
I tried looking for information at
- numpy-1.5.0/doc/source/user/install.rst
- http://docs.scipy.org/doc/
- http://new.scipy.org/building/linux.html
- http://www.scipy.org/Installing_SciPy/Linux
but nothing seemed to apply, and Google only gave me an instance of
Skipper Seabold asking the same question (apparently when building his
own Atlas) only to reply with a somewhat opaque "I figured it out"
message.
Thanks in advance,
Andreas
