Including ButterflyPACK #106

Open mh1git opened 1 year ago

mh1git commented 1 year ago

Hello,

I have built BLAS, LAPACK, SCALAPACK, ButterflyPACK. I am able to get STRUMPACK to recognize BLAS, LAPACK, SCALAPACK but it can't find ButterflyPACK. Here are my build scripts.

Can you please help?

NOTE1 : I built SCALAPACK as a static library. As a result I had to build ButterflyPACK as a static library as well. NOTE2 : I am not certain where ButterflyPACK_DIR needs to point due to the fact there are actually 4 ButterflyPACK precision based static libraries. I tried several places. The path set below causes a CMake configuration error. I tried pointing to the actual static library location (commented out and also given at the end of this log) and STRUMPACK doesn't find ButterflyPACK at all then.

Here is my ButterflyPACK build script which appears to work (produces 4 precision based static libraries in build/lib64

I found the issue. I fixed my scripts in the above comment so that others may find it useful.

No further help needed.

Indeed, to get STRUMPACK to find ButterflyPACK, you set ButterflyPACK_DIR to the directory specified as CMAKE_INSTALL_PREFIX while configuring ButterflyPACK, and then make sure to do a make install for ButterflyPACK.
