my system is raspberry os (64 bit), I have read similar issues: #108 #150, but the issue still occurs.
here is my command:

sudo apt install clang-6.0 libllvm6.0 llvm-6.0-dev
cmake -DMULTI_THREADED=OFF .

here is CmakeError.txt:

You seem to not have any pthread library installed. For a minimal fix you could try to install sudo apt-get install libpthread-stubs0-dev, otherwise I would recommend installing sudo apt install build-essential which also installs GCC, but should provide all other development requirements.

It seems that all the library are installed. However, the issue still occurs.

Just FYI, if you are not aware, VC4CL won't work at all on 64-bit Raspbian or Raspberry Pi 4.

To solve the build problem, the only thing I can think of is to update your GCC, 4.8 is quite old, maybe that fixes something...

Thank you for your reply, VC4CL only works on Raspberry Pi 3B. I just adjust my ML program to 4B and test it in order to save time.
I will try build gcc-6 next week, and I will update if this solve the build problem.

By the way:
64-bit Raspbian is based on Debian, and its package is directly from debian arm64, which means some package is really old.

Is this really only compatible if Raspberry Pi 3B? I'm trying to set it up on my Raspberry Pi 3A and failing so far with the same CMakeErrors as @uniartisan

Also thank you so much for all your work!
