What exactly does linking against atlas do, as the installed contents with and without the atlas variant enabled are identical? At least for my use-case linking against ATLAS instead of vecLib speeds up the computation. It's hard to find any recent data on how vecLib's performance is compared ATLAS, but i guess having the option to use ATLAS doesnt hurt.

Currently SciPy, which has NumPy as a dependency, has multiple variants to support different Fortran compilers. As ATLAS has a hard dependency on gcc43 these multiple variants will have to be removed. I created an enhancement for ATLAS to use gcc variants like SciPy does (see ticket [http://trac.macports.org/ticket/20106 #20106]). If/When it get's accepted i guess this patch could be applied too?

However when I try to build scipy it fails with the following error: {{{ DEBUG: Executing org.macports.build (py25-scipy) DEBUG: Environment: MACOSX_DEPLOYMENT_TARGET='10.5' CCFLAGS='-I/opt/local/include -L/opt/local/lib' DEBUG: Assembled command: 'cd "/opt/local/var/macports/build/_Users_ram_opt_macports_python_py25-scipy/work/scipy-0.7.1" && /opt/local/bin/python2.5 setup.py --no-user-cfg config_fc --fcompiler gnu95 --f77exec /opt/local/bin/gfortran-mp-4.3 --f90exec /opt/local/bin /gfortran-mp-4.3 build' Traceback (most recent call last): File "setup.py", line 160, in <module> setup_package() File "setup.py", line 127, in setup_package from numpy.distutils.core import setup File "/opt/local/lib/python2.5/site-packages/numpy/__init__.py", line 130, in <module> import add_newdocs File "/opt/local/lib/python2.5/site-packages/numpy/add_newdocs.py", line 9, in <module> from lib import add_newdoc File "/opt/local/lib/python2.5/site-packages/numpy/lib/__init__.py", line 13, in <module> from polynomial import * File "/opt/local/lib/python2.5/site-packages/numpy/lib/polynomial.py", line 18, in <module> from numpy.linalg import eigvals, lstsq File "/opt/local/lib/python2.5/site-packages/numpy/linalg/__init__.py", line 47, in <module> from linalg import * File "/opt/local/lib/python2.5/site-packages/numpy/linalg/linalg.py", line 22, in <module> from numpy.linalg import lapack_lite ImportError: dlopen(/opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5 /site-packages/numpy/linalg/lapack_lite.so, 2): Library not loaded: libptf77blas.dylib Referenced from: /opt/local/Library/Frameworks/Python.framework/Versions/2.5/lib/python2.5 /site-packages/numpy/linalg/lapack_lite.so Reason: image not found }}} libptff77blas.dylib is provided by atlas and seems fine: {{{ $ port provides /opt/local/lib/libptf77blas.dylib /opt/local/lib/libptf77blas.dylib is provided by: atlas $ file /opt/local/lib/libptf77blas.dylib /opt/local/lib/libptf77blas.dylib: Mach-O dynamically linked shared library i386 $ ls -l /opt/local/lib/libptf77blas.dylib -rw-r--r-- 2 ram admin 107272 2009-06-18 19:47 /opt/local/lib/libptf77blas.dylib $ }}} Do you not get this error? -- Ticket URL: <http://trac.macports.org/ticket/19966#comment:7> MacPorts <http://www.macports.org/> Ports system for Mac OS
