[Numpy-discussion] numarray 1.3.1 setup patch for mac OS X veclib

[Andrew J. <a....@im...>]

Hi all,

I've had some trouble getting the numarray-1.3.1 setup scripts to 
recognize the optimized BLAS/LAPACK, veclib, on OS X. But I think I've 
tracked down the problems.

First, the section of addons.py that checks for the existence of the
framework (around line 47) needs to set lapack_dirs = [], I think,
since it needs to exist later on.

Second, the section after that that sets lapack_compile_args,
lapack_link_args and lapack_include_dirs for *all* cases (lines 57-60)
overwrites lapack_link_args from the if...elif...else above.

Finally, cblas.h isn't included correctly, since the framework option
is only used for linking, not compiling.

I've attached a patchfile for addons.py below; I switched the two 
sections and added to the framework if... clause. Use it with
    > patch addons.py addons.patch

I hope this is a reasonable way to propagate this to the developers.

Please let me know if it doesn't work for any reason, or if it breaks 
any other install, which I haven't checked. I assume it works on my 
machine, since:

 > otool -L 
build/lib.darwin-7.9.0-Power_Macintosh-2.3/numarray/linear_algebra/
lapack_lite2.so
         /System/Library/Frameworks/Python.framework/Versions/2.3/Python
(compatibility version 2.3.0, current version 2.3.0)
         /System/Library/Frameworks/vecLib.framework/Versions/A/vecLib
(compatibility version 1.0.0, current version 153.2.0)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0,
current version 71.1.3)

p.s. only tested under OS X 10.3.9 (latest version of Panther).
