Hi guys, has anyone successfully compiled Scipy for Python 2.5 under Mac OS X 10.4.8? I notice that the binaries on the webpage only support up to Python 2.4 so I would like to build them. However, running "python setup.py build" I get:

g95 -L/sw/lib build/temp.macosx-10.3-fat-2.5/build/src.macosx-10.3- fat-2.5/Lib/fftpack/_fftpackmodule.o build/temp.macosx-10.3-fat-2.5/ Lib/fftpack/src/zfft.o build/temp.macosx-10.3-fat-2.5/Lib/fftpack/src/ drfft.o build/temp.macosx-10.3-fat-2.5/Lib/fftpack/src/zrfft.o build/ temp.macosx-10.3-fat-2.5/Lib/fftpack/src/zfftnd.o build/ temp.macosx-10.3-fat-2.5/build/src.macosx-10.3-fat-2.5/ fortranobject.o -Lbuild/temp.macosx-10.3-fat-2.5 -ldfftpack -o build/ lib.macosx-10.3-fat-2.5/scipy/fftpack/_fftpack.so /sw/lib/odcctools590/bin/ld: Undefined symbols:

It looks like you have the LDFLAGS environment variable defined. That *overrides* all of the link flags, including the ones that distutils provides to link against the Python libraries. Don't use LDFLAGS.

Robert, At least for me, this is not the case. LDFLAGS is not set, but I get the same "ld: Undefined symbols" error, with both MacPython 2.4 and MacPython 2.5. The failing command is different than Nik's, though. Here is my failing command with MacPython 2.4: error: Command "/usr/local/bin/gfortran -Wall -bundle build/temp.macosx-10.3-fat-2.4/build/src.macosx-10.3-fat-2.4/Lib/fftpack/_fftpackmodule.o build/temp.macosx-10.3-fat-2.4/Lib/fftpack/src/zfft.o build/temp.macosx-10.3-fat-2.4/Lib/fftpack/src/drfft.o build/temp.macosx-10.3-fat-2.4/Lib/fftpack/src/zrfft.o build/temp.macosx-10.3-fat-2.4/Lib/fftpack/src/zfftnd.o build/temp.macosx-10.3-fat-2.4/build/src.macosx-10.3-fat-2.4/fortranobject.o -L/opt/lscsoft/non-lsc/lib -L/usr/local/lib/gcc/i386-apple-darwin8.8.1/4.3.0 -Lbuild/temp.macosx-10.3-fat-2.4 -ldfftpack -lfftw3 -lgfortran -o build/lib.macosx-10.3-fat-2.4/scipy/fftpack/_fftpack.so" failed with exit status 1 Numpy and scipy are fresh from SVN. gfortran is from hpc.sourceforge.net, OS is OSX 10.4, and architecture is Intel Any other ideas? Is there other useful information I could provide? My site.cfg and highlights of my python setup.py config are below.
