FEX: failure to build with -DBUILD_TESTS=True on 18.04

I shoved a few PPAs into 18.04 to attempt to build it on a Jetson Nano - are the following errors a result of my dependencies probably being a mess, or is this something that can be fixed on FEX’s end?

Relevant dependencies below, let me know if I’m missing anything:

cobalt@nano-sd:~/FEX/Build$ cmake --version
cmake version 3.22.0

CMake suite maintained and supported by Kitware (kitware.com/cmake).

cobalt@nano-sd:~/FEX/Build$ clang-13 --version
Ubuntu clang version 13.0.1-++20211124042925+19b8368225dc-1~exp1~20211124043458.31
Target: aarch64-unknown-linux-gnu
Thread model: posix
InstalledDir: /usr/bin
cobalt@nano-sd:~/FEX/Build$

Also I’ve got libstdc++-11-dev and libstdc++6, llvm.org mentioned those were needed from a PPA.

I pulled off a successful build on 18.04! I’m gonna try another one with -DBUILD_TESTS=True, but for now here’s the warning log if anyone’s interested:

FEX itself doesn’t use statx directly. So you could define SYS_statx correctly and hope whatever application you’re attempting to run doesn’t use it. It was added in kernel 4.11 and we don’t expose that low of a kernel version to the guest. Just need to be careful with the syscall numbering on the host
