Hi,<br><br>There's a small problem with the linear algebra library BLAS and LAPACK in opensuse.&nbsp; These are Fortran libraries.&nbsp; I (and others) have trouble using the libraries with SciPy (python scientific computing package).&nbsp; The problem seems to be that different Fortran compilers use different symbol names for some output routines.&nbsp; When one compiles scipy, there are some Fortran routines that get compiled, I think with g77 by default (maybe not).&nbsp; You can compile and install scipy, but when you try importing it in python you get an error of undefined symbol _gfortran_st_write in the LAPACK library.
<br><br>I have the most recent blas and lapack opensuse builds (940).&nbsp; The official suse-type webpage I got these from say they were compiled with egcs, which is a. wrong (egcs merged back into gcc a long time ago) and b. ill-defined (since g77 and gfortran are both part of gcc).
<br><br>As you search the web, you see that it's part of the lore that &quot;Suse's BLAS is buggy, you have to compile yourself.&quot;&nbsp; Not good for Suse!<br><br>While I'm on it, it's not clear what implementation of BLAS opensuse uses.&nbsp; My guess is it's the reference implementation from lapack's page on netlib, which is not optimized.&nbsp; Better ones exist, like gotoBLAS.&nbsp; Maybe that can be made a suse package?
<br><br>At the least it would help if it were spelled out exactly which Fortran compiler was used to make opensuse's blas.&nbsp; If they can be compiled to allow multiple Fortran compilers to play nicely with them, even better.
<br><br><br>Cheers,<br>David<br>
