[Buildroot] Unable to build an image with systemd

[Buildroot] Unable to build an image with systemd

[Gorka Lertxundi]

Hi guys,

Yesterday I run into this issue I didn't know how to proceed, can anyone
help me?

configure: error: *** libmount support required but libraries not found
package/pkg-generic.mk:217: recipe for target
'/buildroot-src/output/build/systemd-234/.stamp_configured' failed
make: *** [/buildroot-src/output/build/systemd-234/.stamp_configured] Error
1

Cross compiling to ARM using the 2017.08.1 release which supposedly has the
systemd and libmount issue solved long time ago[1]. I don't know how it's
possible my build is outputting that all the time.

systemd uses pkg-config to check if libmount exists and, as expected, using
the host-deployed pkg-config wasn't able to find it.

root at 2f591ceac91d:/buildroot-src# /buildroot-src/output/host/bin/pkg-config
--libs blkid
-L/buildroot-src/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib
-lblkid

root at 2f591ceac91d:/buildroot-src# /buildroot-src/output/host/bin/pkg-config
--libs mount
Package mount was not found in the pkg-config search path.
Perhaps you should add the directory containing `mount.pc'
to the PKG_CONFIG_PATH environment variable
Package 'mount', required by 'world', not found

I manually created mount.pc in
"output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib/pkgconfig/mount.pc"
equalling
to the its "twin" blkid.pc content (changing library references of course
;) and this fixes the libmount detection but after a while it crashes:

So something weird is going on or i'm missing something.

Thanks in advance,

Could you please provide a simple Buildroot .config that exhibits the
issue ?

Why "as expected" ?

Why would you do this? It should have been installed by util-linux.

When reporting bug reports, please always include a Buildroot .config
file that allows to reproduce the issue. Also, make sure that the
problem is reproducible after a full clean build, i.e when doing "make
clean all".

Thanks!

As expected because that was the reason why systemd failed in ./configure.
That doesn't mean that it's the root of the problem of course, probably is
my fault...

Yeah, sounds reasonable. Will do next time sorry about that.

I started taking the customizations from jumpnow (
https://github.com/jumpnow/buildroot) and include them one-by-one on the
original buildroot but when I changed from sysv to systemd this one failed
to build.

Just to be sure - You did a make clean when you changed from sysv to
systemd, right?

Peter, Thomas,

Sorry for wasting your time, I thought I already did a clean because I'm
building buildroot inside an ephemeral docker container and this shouldn't
happen (I was caching buildroot through a shared volume...). The build
didn't finish yet but it seems that systemd phase was successfully passed.

Thanks for your support.
