About this mac > system report, I think.

Total number of cores = 4, looks like you do not have any threaded cores.

Works fine with the experiments2 build from https://github.com/Rcomian

sanderbaancentrum · January 30, 2019, 3:26pm

Actually it has threaded cores: Intel Core i7-8559U 1 Processor, 4 Cores, 8 Threads

@sanderbaancentrum its not a good idea to post your serial number…

@Phal-anx thanks, removed

Spinlocks are used as a barrier on the N-1 threads waiting on the last thread to finish stepping (Core AUDIO in your case), so this is expected.

Don’t really understand what you are saying but if this is how multithreading is gonna work its not gonna be usable for me as I am unable to use another app like Ableton besides Rack as Rack takes all the CPU and therefor the rest becomes to slow to use.

Vortico · January 30, 2019, 4:50pm

That’s why you’re able to select the exact number of threads. If you want to leave one for Ableton Live, choose 3 in your case (one less than your physical cores) so Live will be assigned the remaining one by the operating system.

make dep fine

make gives:

clang: error: no such file or directory: ‘dep/lib/libomp.a’

I thought this dependency had gone:

Should be fixed now.

Coirt · January 31, 2019, 1:55pm

Will v1.0 build on windows?

Vortico · January 31, 2019, 2:10pm

It should

Clean clone and then build of 10308b60c6d556ec7715e962676943f19b1997d0.

I’m afraid there is a pile of warnings ending in a error now:

You probably didn’t checkout the submodules.

Coirt · January 31, 2019, 2:19pm

Is that…
git submodule update --init --recursive

Vortico · January 31, 2019, 2:28pm

Yes, that’s the step. You should see the dep/glfw folder populated with files.

Coirt · January 31, 2019, 2:36pm

I’m getting.

fatal: not a git repository (or any of the parent directories): .git
