Dear Bruce, Thanks for the quick reply. I tried again as: python setup.py clean python setup.py build --fcompiler=gnu F77 is used for the compilation: Fortran f77 compiler: /usr/bin/g77 -g -Wall -fno-second-underscore -fPIC -O3 -funroll-loops ... g77:f77: scipy/fftpack/src/dfftpack/dcosqi.f ... but I still get the same errors. What I find strange is that definitions such as PyArg_ParseTupleAndKeywords are defined in the python include files. In my case: /usr/local/opt/python/2.7.2/include/python2.7/modsupport.h:#define PyArg_ParseTupleAndKeywords _PyArg_ParseTupleAndKeywords_SizeT And the right path is given to the compiler: -I/usr/local/opt/python/2.7.2/include/python2.7 I was not confronted with this problem while compiling other modules.

Dear all,

I am having troubles with the compilation of SciPy version 0.10.0b2 on CentOS 5.6. Here is the info: Kernel 2.6.18-238.9.1.el5 x86_64 Python 2.7.2 GCC 4.6.1 ATLAS 3.8.3 (rpm install with yum) NumPy 1.6.1 (compiled, tested and installed successfully)

Defined in the shell: export BLAS=/usr/lib64/atlas/libcblas.so export ATLAS=/usr/lib64/atlas/libatlas.so export LAPACK=/usr/lib64/atlas/liblapack.so

File site.cfg: [DEFAULT] libraries = gfortran, gfortranbegin library_dirs = /usr/local/lib:/usr/local/opt/gcc/4.6.1/lib

When issuing the command: python setup.py build I get a big list of warnings and then error messages. The whole log is in attachment.

After the line: gcc: build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.c

Error messages like this start to show up: /usr/lib/../lib64/crt1.o: In function `_start': (.text+0x20): undefined reference to `main' build/temp.linux-x86_64-2.7/build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.o: In function `f2py_rout__fftpack_destroy_dct1_cache': /software/CC/local/src/python/Libraries/scipy-0.10.0b2/build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.c:2532: undefined reference to `PyArg_ParseTupleAndK eywords' /software/CC/local/src/python/Libraries/scipy-0.10.0b2/build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.c:2543: undefined reference to `PyErr_Occurred' /software/CC/local/src/python/Libraries/scipy-0.10.0b2/build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.c:2553: undefined reference to `Py_BuildValue' build/temp.linux-x86_64-2.7/build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.o: In function `f2py_rout__fftpack_destroy_dct2_cache': /software/CC/local/src/python/Libraries/scipy-0.10.0b2/build/src.linux-x86_64-2.7/scipy/fftpack/_fftpackmodule.c:2471: undefined reference to `PyArg_ParseTupleAndK eywords'

Someone knows why those "undefined reference" errors are showing up?

Thanks in advance for your help.

Raphael

But then it is looking for gfortran (which I know Fedora installs) later on: "F77 : gfortran, version GNU Fortran (GCC) 4.1.2 20080704 (Red Hat 4.1.2-44)"

This is addressed at: http://docs.scipy.org/doc/numpy/user/install.html#fortran-abi-mismatch
