Package: libblis2-pthread
Followup-For: Bug #948954
Hi Jörg, your error refers to openblas, which is a separate BLAS
implementation from blis. The implementations are compatible, but
only when built against libblas.so using -lblas, i.e. when using the
common BLAS ABI.
The appearance of the openblas symbol suggests that your applications
were built using -lopenblas instead of -lblas, enabling some
openblas-specific symbols to be called in.
You've got two options,
1) rebuild your binaries (and to protect from the same problem in the
future, ensure they link strictly against -lblas)
2) install OpenBLAS instead of BLIS (e.g. install libopenblas-pthread-dev)
Together with that you'd probably want to check that the blas
alternatives match, running both
sudo update-alternatives --config libblas.so-x86_64-linux-gnu`
*and*
sudo update-alternatives --config libblas.so.3-x86_64-linux-gnu
