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_ What did I do wrong?
