Hey John, I made some progress by building libnuma with the Android toolchain, then linking against that. I'm now running into issues because bionic does not support shm_open/shm_unlink. It looks like those functions are intentionally not supported as seen here: https://android.googlesource.com/platform/bionic/+/8b14256/docs/status.md Do you have any thoughts on how to proceed? I think I could add a shim for shm_open/shm_unlink that uses memfd in src/include/bionic.h; the memory would only be accessible through /proc, but the tool would at least build. Let me know what you think is best to do here.
