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

I thought this dependency had gone:

Should be fixed now.

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

You probably didn’t checkout the submodules.

Is that…
git submodule update --init --recursive
Yes, that’s the step. You should see the dep/glfw folder populated with files.
I’m getting.
fatal: not a git repository (or any of the parent directories): .git
Should I not be? 
You should be, except of course with the extra step of git checkout v1. You should run git submodule update --init --recursive somewhere in the Rack git repo directory on your computer.

Grand, looks like that’s the one now cheers!
Question on make -j$(nproc) is that physical cores? Iv’e 4 physical 4 threaded will the work be spread over 8 if I do -j8. Iv’e being doing -j4, 8 works but not sure if that is spread over 8 cores.
Best results are to use the number of logical cores. Since compiling is trivially parallelizable, hyperthreading is beneficial.
