Hi,

I compiled lapack, atlas, umfpack, fftw in local folder, in similar way as described here: http://www.scipy.org/Installing_SciPy/Linux on 32bit Ubuntu Precise

In ~/.local/lib I have: ======================================== libamd.2.2.3.a libamd.a -> libamd.2.2.3.a libatlas.a libcblas.a libf77blas.a libfftw3.a libfftw3.la* liblapack.a librefblas.a libsatlas.so* libtmglib.a libumfpack.5.5.2.a libumfpack.a -> libumfpack.5.5.2.a ========================================

In ~/.local/include I have: ======================================== amd.h atlas/ cblas.h clapack.h fftw3.f fftw3.f03 fftw3.h fftw3l.f03 fftw3q.f03 UFconfig.h umfpack.h <various umfpack_[...].h files> ========================================

My site.cfg looks like this: ======================================== [DEFAULT] library_dirs = $HOME/.local/lib include_dirs = $HOME/.local/include

[atlas] atlas_libs = lapack, f77blas, cblas, atlas

[amd] amd_libs = amd

[umfpack] umfpack_libs = umfpack, gfortran

[fftw] libraries = fftw3 ========================================

I extracted numpy and run:

python setup.py build --fcompiler=gnu95 python setup.py install --prefix=$HOME/.local

I then run python interpreter and try to import numpy, when I receive import error:

ImportError: /home/vlad/.local/lib/python2.7/site- packages/numpy/linalg/lapack_lite.so: undefined symbol: zungqr_

Most likely you did not build atlas and/or lapack correctly. Unless you are familiar with debugging those kind of issues, I strongly recommend you to build numpy against atlas as given by ubuntu (something like apt-get install libatlas-base-dev should do the trick). David
