I got this error message on my setup: https://pastebin.com/H2munv1x

@nivata: 'find_package(BLAS)' and 'find_package(LAPACK)' are working on my setup, can you provide the error message?

nivata commented on 2017-06-02 17:10

It seems that 'find_package(BLAS)` no longer works with cmake 3.8.0 and this package. However the `FindBLAS.cmake` says that OpenBLAS is supported. Can we do something about it?

@dbermond & @flying-sheep: done in 0.2.19-2. The pkgrel bump is not really mandatory you can just rebuild the package on your own.

dbermond commented on 2017-05-29 21:35

@eolianoe
Package needs a rebuild against the newly released gcc-libs 7.1.1 (libgfortran.so.4).
Please, update $pkgrel.

@ewtoombs: could you find which flags make the build fails?

This PKGBUILD (version 0.2.19-1 at the time of writing this) isn't working for my CPU (an Intel Wolfdale-3M), and probably many others. I'm getting illegal instruction errors from some kernels calling femms. I fixed it by nuking the CFLAGS. That's what https://aur.archlinux.org/packages/openblas-lapack-git does. For maximum compatibility, that's what this PKGBUILD should do too. My modifications:

```
build(){
cd "${srcdir}/${_PkgName}-${pkgver}"

unset CFLAGS #<---
unset CXXFLAGS #<---
make ${_config} libs netlib shared
}
```

Got an error "OpenBLAS: Detecting CPU failed" on xps 13

Following https://github.com/xianyi/OpenBLAS/issues/983, and searching https://github.com/xianyi/OpenBLAS/blob/develop/cpuid_x86.c for my cpu target (kaby lake seems to be HASWELL) I resolved it by adding TARGET=HASWELL at the end of the make line in build()

chicomag commented on 2016-12-18 02:35

It builds successfully in armv7h arch, so, it's worth adding this target.

Alright, found my mistake. Rebuilding python-scipy-openblas failed because I forgot to rebuild python2-numpy-openblas and scipy also wants to build the pyton2 version in one go.
