Hi,
If someone is interested I succeeded in compile caffe (dev branch) with OpenBlas without changing the code. The only modification is in the makefile I changed the line 188
LIBRARIES += cblas atlas
with
LIBRARIES += opeblas

Sounds good. It is nice to make OpenBLAS into Caffe which #305 and #82 did not finish thoroughly.

Please open a pull request.

Merged. Thanks @AlOa and thanks for the earlier suggestion @kloudkl.

At least on Ubuntu (using the alternatives system) /usr/lib/libblas.so is symlinked to /usr/lib/openblas-base/libopenblas.so, meaning that with just 'blas' everything should work properly (whereas specifying 'openblas' explicitly requires fiddling with environment variables and LIBRARY_DIRS in Makefile.config)

Nevermind, the keyword 'blas' instead of 'openblas' fixed it. Great!

Hi.
what kind of error you get? If you install the openblas/atlas in non
standard directory you must specify BLAS_INCLUDE and BLAS_LIB in the
Makefile.config

I can't get the make all to work with openblas, cblas, or atlas. Keeps
telling me it cannot find the package, even though I'm sure they're all
installed.

Any tips?

link openblas as blas -- works out of the box this way

OpenBLAS is most easily configured by `update-alternatives` or other
symlink strategies.

Linking to blas instead of openblas breaks builds with a manually installed OpenBLAS.
