Bug 690426 – sys-apps/gentoo-functions-0.12: fails to build on musl-1.1.23

• Product: Gentoo Linux
• Status: RESOLVED FIXED

[Description Georgy Yakovlev 2019-07-22 05:19:30 UTC]

A commit landed to musl recently:

https://git.musl-libc.org/cgit/musl/commit/?id=a31a30a0076c284133c0f4dfa32b8b37883ac930

TLDR: they no longer #include <sys/sysmacros.h>
in sys/types.h

thus gentoo-functions fails to build on musl-1.1.23

with

consoletype.c: In function 'check_devnode':
consoletype.c:60:8: warning: implicit declaration of function 'major' [-Wimplicit-function-declaration]
  maj = major(sb.st_rdev);
        ^~~~~
/usr/lib/gcc/x86_64-gentoo-linux-musl/8.3.0/../../../../x86_64-gentoo-linux-musl/bin/ld: /tmp/portage/sys-apps/gentoo-functions-0.12/temp/ccNhcnoC.o: in function `main':
consoletype.c:(.text.startup+0x15a): undefined reference to `major'

This is only an issue for musl due to the GLIBC define in headers.h. This should be assigned to the maintainers and not the musl team.

[Comment 2 Anthony Basile 2019-08-23 15:43:58 UTC]

The correct header to include for the macros major()/minor() is <sys/sysmacros.h>.  This is correct for any libc and I've added the change to gentoo-functions.  See

https://github.com/gentoo/gentoo-functions/commit/1518beca0b5a2730a87da9ce82299ef6469bfe8a

@WilliamH  Do you want to cut a new release of gentoo-functinos.  I've tested on glibc and older versions of musl.  It doesn't break backward compat and it is needed going forward.

[Comment 3 Anthony Basile 2019-08-24 00:23:13 UTC]

I've added the fix to the musl overlay as a stop gap until it hits the main tree:
