[SciPy-user] scipy fblas.so functions not found

[Fahd Sultan]

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 
relocation errors.

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

gcc4-4.1.1-53.EL4.x86_64.rpm
gcc4-c++-4.1.1-53.EL4.x86_64.rpm
gcc4-gfortran-4.1.1-53.EL4.x86_64.rpm
libgcj4-4.1.1-53.EL4.x86_64.rpm
libgcj4-devel-4.1.1-53.EL4.x86_64.rpm
libgfortran-4.1.1-53.EL4.x86_64.rpm
libgomp-4.1.1-53.EL4.x86_64.rpm
libmudflap-4.1.1-53.EL4.x86_64.rpm

this time I was able to build lapack. I then installed both lapack and 
blas and their devel rpms.

lapack-3.1.1-1.x86_64.rpm
blas-3.1.1-1.x86_64.rpm

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 
for scipy.
fftw-3.1.2-3
fftw-devel-3.1.2-3

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 
lib path.

after installing scipy I tested numpy and scipy with

 >>> import numpy, scipy
 >>> numpy.test()
 >>> scipy.test()

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  
http://www.sharova.com/scipy_rhas44x86_64/

good luck,

Fahd
