Bug ID: 111406
Summary: libiberty build produces errors with CC=clang,
unsupported option '-print-multi-os-directory'
Product: gcc
Version: unknown
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: other
Assignee: unassigned at gcc dot gnu.org
Reporter: dilfridge at gentoo dot org
Target Milestone: ---
This is a clone of https://bugs.gentoo.org/913750
With CC=clang, the build of libiberty (as part of gnu binutils)
produces errors
clang-16: error: unsupported option '-print-multi-os-directory'
clang-16: error: no input files
However, the build continues apparently fine...
This stems from libiberty/Makefile.am:
385 # This is tricky. Even though CC in the Makefile contains
386 # multilib-specific flags, it's overridden by FLAGS_TO_PASS from the
387 # default multilib, so we have to take CFLAGS into account as well,
388 # since it will be passed the multilib flags.
389 MULTIOSDIR = `$(CC) $(CFLAGS) -print-multi-os-directory`

You mean Makefile.in, libiberty does not use automake.

--- Comment #3 from Richard Biener <rguenth at gcc dot gnu.org> ---
These are only used in the install targets which when bootstrapped will have
used GCC from earlier stages. When building cross compilers we require GCC as
host compiler.
So I think this isn't an issue unless you try to build libiberty stand-alone
or as part of binutils and also install it?
The sourceware bugzilla instance also doesn't have a libiberty component,
so tracking it here is possibly good enough but as said above you'll not hit
it in practice?

We have a binutils-libs package, which installs libbfd, libctf, libopcodes,
libsframe, and a statical libiberty.a
