openBLAS not found

[gabora]

Hi,
I installed OpenBLAS, but the setup.py didn't find it.

The problem is that I didnt install OpenBLAS to any of the presumed locations (/opt/... or /usr/...) in setup.py (defined in the ldirs variable) because I have no permission to install there.

As a user I only get the error message,
/usr/bin/ld: cannot find -lopenblas

Once I added modified the ldirs variable and added the correct OpenBLAS path, this issue was solved.

please consider adding a better error message, or maybe highlight in the installation process, that OpenBLAS has to be installed to a certain location.
thanks for considering, let's save some time for others.
best,
Attila

Hi,
Thanks for the bug report. I'll make it more clear in the installation instructions where the OpenBLAS is searched for.

Hi,
What is the correct OpenBLAS path? just a path to the OpenBLAS directory itself, or something within it?

Hi,
It is the libs directory of OpenBLAS.
The line to modify is setup.py:110
ldirs = ["/opt/OpenBLAS/lib", "/usr/local/lib", "/usr/lib/openblas-base", "/usr/local/lib/gcc/7", "/usr/local/opt/openblas/lib", "/usr/local/opt/gcc/lib/gcc/5"].
