RFE: gcc43 variant for py25-numpy

[jochen@…]

Can we please get back the gcc43 variant for py25-numpy?

I would like to build my complete toolchain, including numy and scipy, as well as my own code, using gfortran from GCC-4.3. It worked nicely until recently. Why were the already working variants removed?

py-numpy/py25-numpy: remove unnecessary fortran variants

Don't know why they are supposed to be unnecessary? I want them back;-)

What error are you getting? I have successfully used f2py and gfortran from gcc43 without having the specific variants?

[jochen@…]

No specific error, but for one I don't want g95 on my system at all, and second I am not sure it is safe to mix these Fortran compilers, esp. when they are form different GCC versions.

Replying to jochen@macports.org:

The numpy ports don't depend on g95 any more, as officially numpy does not support g95 under Mac OS X:

I installed numpy-1.0.4 using gfortran from gcc42 and compared that to using gcc43 and specifiying no fortran compiler. I couldn't find any differences. Also scipy builds (and passes the test suite), with gcc42 and gcc43, against numpy built without a fortran compiler. I haven't tested for any differences in the installed product with numpy-1.1.0 - but scipy passes the test suite.

Its a good point about mixing of compiler versions, I have never had any problems though.

I can re-add the fortran variants to numpy if you would be happier.

Just asked on the NumPy Discussion mailing list about whether installing a fortran compiler effects anything:

​http://projects.scipy.org/pipermail/numpy-discussion/2008-June/035046.html

essentially the answer is that it doesn't effect anything, its only an issue if you need to build against a LAPACK or BLAS that needs to be linked using a fortran compiler. We don't so I don't think that we need to have specific fortran compiler variants.
