Installation problem on Ubuntu Linux

Open ArchRobison opened this issue 9 years ago • 3 comments

I was trying to install Vector.jl on a Ubuntu box with a i7-5820K processor, and got a bunch of errors. See log here for details. There's a bunch of sysctl: permission denied problems that lead up to a message:

ERROR: LoadError: LoadError: Current platform does not support AVX, AVX2 or AVX512

The i7-5820K supports AVX and AVX2. What should I try?

The error is because I'm using sysctl to determine whether a particular processor supports AVX/AVX2.0/AVX512 - I'm guessing that your permissions on that system don't allow for calling sysctl -a? However, I believe I have a method that bypasses using sysctl - I'll see if I can't fix it in the next 48 hours.

Ok - this issue should be fixed. There are no more calls to sysctl, and by loading the correct MKL library I have bypassed the need to verify processor instruction sets.

Let me know if the master works on this machine?

Thanks again for trying it out!

Did you get the chance to verify that this issue was fixed?
