NimBLAS should always use the cblas API #4
Conversation

Thank you. All distrubutions I usually use ship cblas with blas itself, I did not know about a separate cblas |
|
Sorry, I had to revert the PR. I assumed you had tested on various distributions, but this already fails on Ubuntu. Since the previous version works on Debian, Rad Hat and their derivatives, I am going back. I assume the issue only appears in Manjaro |
|
It fails on Arch as well (which Manjaro is a derivative of). Looking into http://nicolas.limare.net/pro/notes/2014/10/31_cblas_clapack_lapacke/ and https://discuss.mxnet.io/t/build-failure-with-use-blas-blas-in-arch-linux/618 It seems like Archlinux choose to split the C and Fortran interface while other distros do not. |

What could be a good way to handle this? Can we use |
|
I don't think there is a proper way besides documentation. |
|
I added some in the README |
Currently nimblas try to use cblas_ddot (in nimblas CI) and cblas_dgemm (in Arraymancer CI).
Unfortunately those functions are not available in the default
libblas.soshipped in Linux distributions.Instead nimblas should always dlopen
libcblas.socc @narimiran @Araq for popular repos testing.
edit: fix #3
