[SciPy-user] scipy fblas.so functions not found
Fri Jun 22 01:14:12 CDT 2007
I was trying the build on the same arch. I have managed to build
scipy/numpy. Please read below of how I did it.
frist I installed from the redhat cd gcc4, gcc4-fortran, and libgfortran.
When I tried to build lapack-3.1.1-1.fc7.src.rpm I got the same
I figured that something wasn't write, so I I built
gcc4-4.1.1-53.EL4.src.rpm from src. I checked the Makefile before hand
and it seemed to be configured to build the libraries shared.
from the resulting rpms I installed
this time I was able to build lapack. I then installed both lapack and
blas and their devel rpms.
I downloaded, built and install numpy-1.0.3-1.src.rpm. I found
scipy-0.5.1-1.src.rpm on rpmfind, and fftw-3.1.2-3.fc6.src.rpm a prereq
I had to alter the fc7 src rpm's spec files to change the gcc-gfortan
prereq to gcc4-gfortran and before building scipy I had to export
BLAS=/usr/lib64 and LAPACK=/usr/lib64 even though I had the dir in my
after installing scipy I tested numpy and scipy with
>>> import numpy, scipy
The numpy test passed however some (?) of the scipy test failed. I
tried the examples on http://www.scipy.org/scipy_Example_List and they
seemed to work.
I've put the rpms I built (along with src rpms) up at
build server: vmware virtual server redhat AS 4.4
