@xyproto: I'm fine with the move to [community] but if I'm not wrong some optimisations depend on the type of the CPU, not as strongly as atlas does but it may decrease the performance.

@eolianoe I'm considering adopting+moving openblac-lapack to [community], making it an official package, if you're fine with it.

My problem seems related to the new AMD CPUs based on the Zen architecture, in my case I own a R7 1700.


Confirmed that from the git repository I can build without errors.

@eolianoe I'm sorry. I was using old version of gcc because I had `/opt/cuda/bin` at the start of my PATH.

@adfjjv: comes from a previous version of gcc/gfortran and you need to rebuild each package that depends on the old version of the library. To be sure that everything is properly linked, clean the build directory and rebuild the packages that depends on

@eolianoe rebuild which package? I am building openblas-lapack (on 2 different arch machines). Maybe you can help point me to reasons why the build script thinks I have instead of

@adfjjv: you just need to rebuild the package in order to link with the new library.

@marcs: it seems that your build is failing with the first file (getarch_2nd.c) and then there are errors because some variables are not defined.
I've no idea why it is failing, you may try to build using only one CPU (add MAKE_NB_JOBS=1 in the _config variable in the PKGBUILD). If it's still failing you should report the issue upstream with some details, like the CPU you are using.
