[Numpy-discussion] building numpy locally but get error: undefined symbol: zgesdd_
Tue Sep 16 01:58:20 CDT 2008
I am trying to install python2.5/scipy/numpy/sympy/matplotlib locally,
because of various reasons. I am not root.
At home I am using Ubuntu and I am root and everything works as it should.
So far I managed to make python2.5, sympy and ipython to run fine on
my computer at work, but I am struggling to make numpy+scipy since I
am trying to install it locally. The problem is likely the
lapack+atlas build. I have followed the build by hand instructions on
http://www.scipy.org/Installing_SciPy/Linux. I am not getting any
errors during the build and install.
However after installing I tried to import numpy in python and
received to following error: ImportError:
undefined symbol: zgesdd_
Googling this error, it seems that the error is caused by having a
wrong lapack version. I am running Centos 5 (basically Red Hat
Enterprise Linux 5) on a x86_64 machine.
Does anybody know how I can get the right version, by changing some
flags, or whatever? FYI I have added the -m64 flag for the lapack
build, but no change.
