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:

How can I solve this? Wish some one can help me :)

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.

What are your versions of:

CMake
/usr/bin/cc

Answer 5 · 2021-06-12T09:10:47.000Z

Cmake:3.16.3-3~bpo10+1
gcc/g++:4:8.3.0-1

Thx a lot for your time, I have verified my project on the Raspberry Pi 4B. :)

Answer 6 · 2021-06-12T09:43:41.000Z

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.
