Linking to openblas #792

Closed akopich closed 4 years ago

akopich commented 4 years ago

Hi all.

I'm struggling to make breeze link to openblas. I have breeze-natives dependency included (replacing it with an explicit dependence on netlib-java doesn't help). Apparently, the linker sees blas

# ldconfig -p  | grep blas 
        libopenblas.so.3 (libc6,x86-64) => /usr/lib/libopenblas.so.3
        libopenblas.so (libc6,x86-64) => /usr/lib/libopenblas.so
        liblasem-0.4.so.4 (libc6,x86-64) => /usr/lib/liblasem-0.4.so.4
        liblasem-0.4.so (libc6,x86-64) => /usr/lib/liblasem-0.4.so
        libcblas.so.3 (libc6,x86-64) => /usr/lib/libcblas.so.3
        libcblas.so (libc6,x86-64) => /usr/lib/libcblas.so

I'm running the app with sbt run under Linux.

NVM, I needed to install libgfortran3 (and the "3" part is important).

Sorry for being slow. Yeah, this is a common issue. I should add an FAQ or something.

libgfortran3 is not available in newer ubuntu distributions anymore...

https://packages.ubuntu.com/search?keywords=libgfortran3

What should I do in this case?
