5 months ago When investigating this issue, I found that building Python on FreeBSD with --enable-profiling, which leads to adding the -pg compile flag on x86_64, will cause the compiled binary to crash. This will mislead autoconf tools and result in invalid compiler/linker flags.
In my case, it wrongly specified -latomic linker flags, resulting in the compiling process stopping. This is described in issue #117452.
I suspect this is the same issue, but you are using an ARM machine, so the behavior may be different (-latomic is needed when building on ARM). Since I don't have an ARM device on which FreeBSD can run, I can't ensure this. Could you please check and post the config.log here in the CPython repository's root path after configuring and making?

Can you share the link of the FreeBSD issue?
Since the issue is in FreeBSD and not in Python (can be reproduced with a short C program), the issue was reported to FreeBSD, I close the issue. There is no need to track the issue in the Python bug tracker.
