Ralf, I downloaded scipy from svn. Then I did the command: $ LDFLAGS="-lgfortran -arch x86_64" FFLAGS="-arch x86_64" sudo python setupscons.py install Trying this dies with: scons: done building targets. Executing scons command (pkg is scipy.fftpack): /usr/bin/python "/Library/Python/2.6/site-packages/numscons-0.10.1-py2.6.egg/numscons/scons-local/scons.py" -f scipy/fftpack/SConstruct -I. scons_tool_path="" src_dir="scipy/fftpack" pkg_name="scipy.fftpack" log_level=50 distutils_libdir="../../../../build/lib.macosx-10.6-universal-2.6" cc_opt=gcc-4.2 cc_opt_path="/usr/bin" f77_opt=gfortran f77_opt_path="/usr/local/bin" cxx_opt=g++-4.2 cxx_opt_path="/usr/bin" include_bootstrap=/Library/Python/2.6/site-packages/numpy-1.3.0-py2.6-macosx-10.6-universal.egg/numpy/core/include silent=0 bootstrapping=0 scons: Reading SConscript files ...

See above for more information. If you think it is a problem in numscons, you can also try executing the scons command with --log-level option for more detailed output of what numscons is doing, for example --log-level=0; the lowest the level is, the more detailed the output it. Any clues? Thanks.

When I try to build from the distribution, I get a huge number of library architecture errors. I've tried to build both against the python that comes with the system (2.6.1) and against the MacPort python (2.6.5) (see test summary at end of message). When I try to install via MacPort, it appears to install but much functionality is missing (e.g. curve_fit) that I assume is because the BLAS and LAPACK libraries aren't being linked to correctly. I'm using OS 10.6.2 on an Intel iMac. The latest Xcode is installed (3.2.1) with: i686-apple-darwin10-gcc-4.2.1 (GCC) 4.2.1 (Apple Inc. build 5646) (dot 1) gfortran from research.att.acom: GNU Fortran (GCC) 4.2.3 I would appreciate suggestions. How are you trying to build? The error suggests you are building for the wrong achitecture (32 vs 64-bit). I have been able to build against the Apple-provided python but not the python.org version so far. The difference is that the former is 64-bit while the latter is 32-bit. For Apple Python, install numscons ( http://projects.scipy.org/numpy/wiki/NumScons ) and gfortran (from http://r.research.att.com/tools/ ) and use: $ LDFLAGS="-lgfortran -arch x86_64" FFLAGS="-arch x86_64" python setupscons.py scons Cheers, Ralf _______________________________________________ SciPy-Dev mailing list SciPy-Dev@scipy.org http://mail.scipy.org/mailman/listinfo/scipy-dev
