Description Olaf Leidinger 2014-02-26 17:13:20 UTC
On Gentoo-hardened with selinux enabled, build fails as make doesn't know how to create -L/usr/lib. The relevant parts of the Makefile are the following:

libmount.la: $(libmount_la_OBJECTS) $(libmount_la_DEPENDENCIES) $(EXTRA_libmount_la_DEPENDENCIES)
        $(AM_V_CCLD)$(libmount_la_LINK) $(am_libmount_la_rpath) $(libmount_la_OBJECTS) $(libmount_la_LIBADD) $(LIBS)


libmount_la_DEPENDENCIES = \
        $(libmount_la_LIBADD) \
        libmount/src/libmount.sym \
        libmount/src/libmount.h.in

libmount_la_LIBADD = libcommon.la libblkid.la $(SELINUX_LIBS)

SELINUX_LIBS is set to the output of pkg-config --libs libselinux, which is
-L/usr/lib -lselinux

Thus, -L/usr/lib is listed as a build-time dependency and clearly, make doesn't know how to create it.

Reproducible: Always

patch to current ebuild (2.24.1-r2)

As the fixed build dependencies change Makefile.am, a regeneration of Makefile.in is needed. The patch to the ebuild reflects that.

Comment 4 Samuli Suominen (RETIRED) gentoo-dev 2014-02-26 19:09:19 UTC
See bug 481782, Comment #5 and up to #7

Output of libselinux shouldn't mention -L/usr/lib at all, it should omit native library directory

What version of libselinux and/or libsepol is this? Does upgrading to very latest change anything?
Comment 5 Samuli Suominen (RETIRED) gentoo-dev 2014-02-26 19:12:17 UTC
pastebin the /usr/lib/pkgconfig/selinux.pc and 'emerge -pv libselinux'
it should NOT list -L/usr/lib
and what pkg-config are you using? output of 'emerge -pv --nodeps dev-util/pkgconfig dev-util/pkgconf`?
Comment 6 Olaf Leidinger 2014-02-26 22:51:16 UTC
Here is the output pastebin-ed:
http://pastebin.com/hwjCqJRf

The libsepol-bug is related, I think, as the pkgbuild file, which was generated for libselinux sets libdir to /usr/lib instead of /usr/lib64 for my 64bit system. If this was fixed, util-linux would build properly.

However, the dependency in the Makefile is wrong, anyway. If one installs libselinux to a non-standard path, things will break. This won't happen on Gentoo when installing everything via portage, so a fix for libselinux's pkgconfig-file generation would be sufficient in our case.
Comment 7 SpanKY gentoo-dev 2014-02-26 23:58:13 UTC
paste the output here.  external links die & are useless.

ignoring the -L thing, we don't want -lfoo showing up in make deps either.  so upstream might be setting vars wrong ...

Comment 9 Olaf Leidinger 2014-02-27 06:54:19 UTC
I had a look at how libselinux.pc was generated. This is the relevant part from the Makefile:


LIBDIR ?= $(PREFIX)/lib
LIBBASE ?= $(shell basename $(LIBDIR))
LIBPC=libselinux.pc

[...]

$(LIBPC): $(LIBPC).in ../VERSION
        sed -e 's/@VERSION@/$(VERSION)/; s:@prefix@:$(PREFIX):; s:@libdir@:$(LIBBASE):; s:@includedir@:$(INCLUDEDIR):' < $< > $@

####### libselinux.pc.in ##
prefix=@prefix@
exec_prefix=${prefix}
libdir=${exec_prefix}/@libdir@
includedir=@includedir@

Name: libselinux
Description: SELinux utility library
Version: @VERSION@
URL: http://userspace.selinuxproject.org/
Requires.private: libsepol libpcre
Libs: -L${libdir} -lselinux
Cflags: -I${includedir}
###########################

If I call make manually with:

LIBDIR=/usr/lib64 make

The generated libselinux.pc is fine. So I assume, that the variable is set wrongly in the ebuild.

^ broken, identical bug to 481782
Comment 11 Samuli Suominen (RETIRED) gentoo-dev 2014-02-27 08:55:49 UTC
what makes this even worse is that libselinux has ABI_X86="32" support and the /usr/lib32/pkgconfig/libselinux.pc also returns -L/usr/lib

so while util-linux could propably be adjusted to ignore this bug, the actual bug is really in libselinux, there is no way around that
Comment 12 Olaf Leidinger 2014-02-27 09:03:56 UTC
I agree, libselinux should be fixed (which would make the current release of utils-linux work for us as it is) and the dependency issue should be fixed upstream. I reported it there already, (c.f. the link above) so nothing to do for util-linux downstream.
Comment 13 Sven Vermeulen (RETIRED) gentoo-dev 2014-03-04 19:18:02 UTC
libselinux-2.2.2-r2 has the src_compile() now also running with LIBDIR and SHLIBDIR set (it was previously only set for the install phase).

~$ pkg-config --libs libselinux
-lselinux

~$ $ cat /usr/lib64/pkgconfig/libselinux.pc 
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib64
includedir=/usr/include

I'll look into bug 502954 as soon as I can too.

Works for me, thanks!

By the way, my patch made it upstream, so the next util-linux version won't have this dependency problem anymore. Thank's for fixing!
