Running Ubuntu 11.10 + python2.7…built numpy from source and installed it, but when I go to install it, I get
ImportError: /usr/lib/liblapack.so.3gf: undefined symbol: ATL_chemv
when it tries to import lapack_lite from numpy.linalg. I tried to rebuild lapack from scratch, but it seems to just make
/usr/local/lib/libblas.a
/usr/local/lib/liblapack.a
/usr/local/lib/libtmglib.a
and the .so file. Where does the .so.3gf come from, and how do I fix it?
I was having the same problem and removing the package libopenblas-base did the trick:
As already explained by others, several packages provide incompatible versions of liblapack.so.3gf.
