How to check which BLAS is in my Ubuntu system?

Question

In particular, I would like to know if xianyi's OpenBLAS has been installed. I work on several PCs and had it installed in several PCs over the past couple of years, but I lost track which were not installed with it. I need to know which PC has it and which doesn't This is how I installed it:

git clone git://github.com/xianyi/OpenBLAS
cd OpenBLAS
make FC=gfortran
sudo make PREFIX=/usr/local/ install

Note: I may have deleted the OpenBLAS directory, so it's not a reliable indicator. And I have no idea how to uninstall it, so I can't try installing it on every PC and then uninstall selectively (which is pretty cumbersome).

Solution

In include dir there is openblas_config.h You can find openblas version there. i.e.

grep OPENBLAS_VERSION /usr/local/include/openblas_config.h
