Description Ciro Santilli 2018-03-14 12:08:47 UTC
7d43534625ac06ae01987113e912ffaf1aec2302 post 2018.02, then:

     make qemu_x86_64_defconfig
     printf 'BR2_PACKAGE_OPENBLAS=y\n' >>.config
     make olddefconfig
     time make BR2_JLEVEL="$(nproc)"

Fails with:

    /home/ciro/bak/git/buildroot/output/host/bin/x86_64-buildroot-linux-uclibc-ar: sgemm_kernel.o: No such file or directory                                                                                           

The build works however if I set:

    BR2_PACKAGE_OPENBLAS_TARGET="NEHALEM"

while the default was "SSE_GENERIC", and I am able to run a simple test program on qemu like that.

There are a few reports on their bug tracker e.g.: 
https://github.com/xianyi/OpenBLAS/issues/502

Not sure if we should just change the default, or just update the package, or something else.

I tried upgrading to master at 2c7392f07bb8023adbc7b85c049d16607ade77e1 but it fails with:

so something with the `source.buildroot.org` cache that I don't understand.
