Silent grab external dependency from libuuid during build without possibility to disable it #100369
Closed as not planned
Description
Bug report
During build process of the python it silent grab external (not in base system, but installed from ports) dependency from libuuid (misc/e2fsprogs-libuuid):
checking uuid.h usability... yes
checking uuid.h presence... yes
checking for uuid.h... yes
checking for uuid_generate_time_safe... no
checking for uuid_generate_time in -luuid... yes
checking for uuid_create... yes
checking for uuid_enc_be... yes
Without libuuid (misc/e2fsprogs-libuuid) installed:
checking uuid.h usability... yes
checking uuid.h presence... yes
checking for uuid.h... yes
checking for uuid_generate_time_safe... no
checking for uuid_generate_time in -luuid... no
checking for uuid_create... yes
checking for uuid_enc_be... yes
And it's impossible to disable this behavior without additional patches to configure script.
Your environment
- CPython versions tested on: 3.10.9
- Operating system and architecture: FreeBSD 13.1-p5 amd64
IMHO, best solution is to add an options to configure script, for example: --disable-libuuid and --enable-libuuid.
Additionally: base system have uuid.h and misc/e2fsprogs-libuuid have uuid/uuid.h - better check for uuid.h if --disable-libuuid used and for uuid/uuid.h if --enable-libuuid.
P.S. Sorry for my poor english.

Reading the code for configure.ac, I am pretty sure this is not an issue anymore since GH-29741, which cleaned up the uuid module in a couple ways including refactoring the configure checks to use pkg-config.
A side effect of this is that it actually checks properly for different providers of uuid -- and if it finds the FreeBSD base system version of uuid.h, it marks it as found and doesn't attempt to either probe it with pkg-config, or fall back on AC_CHECK_LIB. Therefore it won't ever find it in ports.

Dunno if that's worth backporting from 3.11 to 3.10, at the very least that commit would need to be reduced and only part of it applied.

Look like not backported yet.

This is fixed in 3.12 and can no longer be fixed in 3.10, leaving only 3.11 in question. The change is subtle enough that I'm not excited about trying to pick out (or review) the right bits to backport, so I'm going to go ahead and close the issue.
