cannot launch Julia after installing MKL.jl

[JianghuiDu]

Windows 10. Julia v.1.1.0. Just added MKL.jl. All seems successful during installation but after that Julia crashed and cannot be launched anymore.

Tried again, here is the error after installation

julia> using MKL

Thanks for reporting. I can confirm the issue with Julia 1.1. I used to work with Julia 1.0.2 and I'm now testing it again with 1.0.3.

@staticfloat Any idea what could have happened here? I had this working locally on 1.0.2 and AppVeyor passed two months ago with 1.0.3. I can now reproduce this locally with 1.0.2, 1.0.3, and 1.1. What could have changed?

Can you run inside of gdb or lldb and tell me where it's crashing?

[andreasnoack]

I managed to get a gdb but I doubt the result is useful

Is this only happening on Windows?

[andreasnoack]

Yes. It works on Mac and Linux.

I encountered the same problem in Julia 1.1.1 (Windows 10). How can I solve this problem?😭

See the README:

It is not possible to revert the effect of install MKL.jl. To return to OpenBLAS, it is necessary to reinstall Julia.
