[Question] Build error: "mm_malloc.h: No such file or directory" (aarch64 Ubuntu 22.04 running on UTM) about p4-guide HOT 3 CLOSED

Agreed with your analysis that file mm_malloc.h exists on amd64 architecture Ubuntu 22.04, but not aarch64. I have filed this issue on p4c to let developers know about this issue: p4lang/p4c#4639

Until they change things to enable compiling on aarch64 Ubuntu again (I have no idea how long that might be), I would recommend modifying your copy of the install-p4dev-v7.sh script to add the git checkout line shown below:

    # Clone p4c and its submodules:
    get_from_nearest https://github.com/p4lang/p4c.git p4c.tar.gz
    cd p4c
    # Use a version of p4c source before it broke the build for Ubuntu 22.04 on aarch64 processors
    git checkout 6e20abe20702c3f7e20a8c5c642e1d7a4ab01559
    git log -n 1

from p4-guide.

This might be due to changes in p4c since last month, the last time I tested this install script on arm64 Ubuntu 22.04.

I am running this test script again now (along with other processor/OS-version combinations) to get updated results, and let you know if I see this, too.

It seems that the P4 development tools was successfully installed with the modified install-p4dev-v7.sh script.
Thank you for helping me out!
