Hi Jerry, It looks like CMake can’t find the OpenMP libraries. If you install them via `sudo apt-get libomp-dev` it might work.If that fails, you can try and compile the software without multithreading support, by running `cmake .. -DNO_MULTITHREADING=1` I hope that helps,Zac.

I tried to cross compile on ubuntu 20 LTS x86-64 for aarch64 devices, and it failed.
I also tried the dockerfile, but the image's not on the Dockerhub anymore.
It could be the issue of aarch64 lib paths retrieval on x84-64, but after checking https://github.com/AztecProtocol/barretenberg/blob/master/barretenberg/cmake/toolchains/arm64-linux-gcc.cmake I can't find anything suspicious for me to try.
Any input is appreciated.
