What do you mean by own extensions to NumPy ? If you mean building extensions against the C API of NumPy, then you don't need to build your own NumPy. Building NumPy with Intel Compilers and MKL is a non-trivial process, so I would rather avoid it. I want to have exact control which version of numpy I use. In
If you still want to build it by yourself, could you give us the full output of your build ? My site.cfg looks like: [mkl]
Thanks for your response, David. particular, I want to use the current development version. library_dirs = /opt/intel/lib/intel64:/opt/intel/mkl/lib/intel64 include_dirs = /opt/intel/include/ mkl_libs = mkl_def, mkl_intel_lp64, mkl_intel_thread, mkl_core, iomp5 lapack_libs = mkl_lapack95_lp64 and I build numpy by python setup.py config --compiler=intelem --fcompiler=intelem build_clib --compiler=intelem --fcompiler=intelem build_ext --compiler=intelem --fcompiler=intelem install > log.txt https://gist.github.com/2213552 is the content of log.txt. There were no outputs on stderr. I asume that the warnings can be ignored. However, there is a frequent error: _configtest.c(5): error: the size of an array must be greater than zero static int test_array [1 - 2 * !(((long) (sizeof (npy_check_sizeof_type))) == 12)]; ^ compilation aborted for _configtest.c (code 2) How can I get rid of it? Thanks, Christoph
