I try to modify buildscripts/cblas.def into

headers=cblas.h
compilerOpts = -I/usr/include/x86_64-linux-gnu -I/usr/local/opt/openblas/include
linkerOpts = -L/usr/lib -L/usr/lib/x86_64-linux-gnu -L/usr/local/opt/openblas/lib -lblas

and buildscripts/lapacke.def into

headers=lapacke.h
compilerOpts = -I/usr/local/opt/lapack/include
linkerOpts = -L/usr/lib -L/usr/lib/x86_64-linux-gnu -L/usr/local/opt/lapack/lib -llapacke

but no result, any idea?

Turns out there is another cblas.def and lapacke.def file inside koma-core/native-cblas which needs to be updated also. After that building works fine

kyonifer commented 6 years ago

Sorry for the confusion. The def files in buildscripts are remnants from the pre-multiplatform build system (before kotlin/native supported multiplatform) and aren't actually being used by anything. I removed them in cbacd1eb09622764ce155be57dfd2fff5a2c363e.
