The last two lines should have been interchanged of course: $ cd isingmodel $ hg up db7dd01cdc26 Also you may want to edit the Makefile: all: f2py --fcompiler=gnu95 --f77flags="-W -Wall -fdefault-real-8" -c -m mcising mcising.f cython pyising.pyx gcc -fPIC -O3 -I/usr/include/python2.4/ -I/usr/share/python-support/python-numpy/numpy/core/include/numpy/ -c -o pyising.o pyising.c gcc -shared pyising.o -o pyising.so Especially the include path to numpy/*.h files.
