[Buildroot] systemd: build failure against pam on arm

[Buildroot] systemd: build failure against pam on arm

[Christian Stewart]

Hi all,

Compiling against 2017.05, with the following defconfig:

BR2_arm=y
BR2_cortex_a15=y
BR2_ARM_FPU_NEON_VFPV4=y
BR2_OPTIMIZE_2=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_SYSTEMD=y
# BR2_TARGET_ROOTFS_TAR is not set
BR2_PACKAGE_LINUX_PAM=y

I get this error consistently during the systemd compilation when PAM
is enabled:

/output/host/opt/ext-toolchain/bin/../lib/gcc/arm-linux-gnueabihf/6.3.1/../../../../arm-linux-gnueabihf/bin/ld.gold:
error: /lib/libpam.so: incompatible target
/output/host/opt/ext-toolchain/bin/../lib/gcc/arm-linux-gnueabihf/6.3.1/../../../../arm-linux-gnueabihf/bin/ld.gold:
error: /lib/libpam_misc.so: incompatible target
collect2: error: ld returned 1 exit status

It looks like it's attempting to link against /lib/libpam.so from my system.

This is a pretty huge showstopper!

Thanks,
Christian Stewart

Can you paste a few more lines above this error?

I cannot reproduce it here, not even after install libpam0g-dev on my
build host.

Reproduced on several Gentoo machines. The environment looks clean. It
compiles just fine on any commit before
400eaa3452e9380ec77ac62266530055506ea6e7.

Hi,

can you make the last failing link command more verbose?
CCLD should be expanded to the full command used.

best regards

I'm still seeing this error under Gentoo against 2017.11:

>>> systemd 234 Building

PATH="/buildroot/host/bin:/buildroot/host/sbin:/usr/x86_64-pc-linux-gnu/gcc-bin/6.4.0:/usr/local/bin:/usr/bin:/bin:/opt/bin:/opt/golang/bin  /usr/bin/make -j5  -C /buildroot/build/systemd-234/

collect2: error: ld returned 1 exit status

I believe on Gentoo some sort of environment leakage is breaking the lib path.

defconfig:

BR2_arm=y
BR2_cortex_a9=y
BR2_ARM_ENABLE_NEON=y
BR2_ARM_ENABLE_VFP=y
BR2_ARM_INSTRUCTIONS_THUMB2=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_INIT_SYSTEMD=y


This has been an issue for quite some time, and the reason why I have
not upgraded past the early 2017 release. I finally upgraded to 2017.11
and have found that it's once again broken compilations on my machine.

I'm not sure how to get Buildroot to produce a more verbose CCLD output,
I have tried "make VERBOSE=1" but this doesn't give me more than shown above.

I previously bisected the issue down to commit 400eaa3452 if that helps.

That commit bumped the linux headers (I believe) from 4.9.9 to 4.10.0.

Best,
Christian Stewart

I have found that the defconfig I sent in my previous email does not
reproduce the issue. The issue can successfully be reproduced against
2017.11 with the following defconfig:

BR2_arm=y
BR2_cortex_a7=y
BR2_ARM_FPU_NEON_VFPV4=y
BR2_CCACHE=y
BR2_OPTIMIZE_2=y
BR2_TOOLCHAIN_BUILDROOT_GLIBC=y

BR2_SYSTEM_BIN_SH_BASH=y
BR2_ENABLE_LOCALE_WHITELIST="C en_US en_US.UTF-8"
BR2_GENERATE_LOCALE="en_US.UTF-8"
BR2_PACKAGE_BUSYBOX_SELINUX=y

I'm not sure what it is in this set of config options that causes the problem.

I went back and figured out how to make autotools verbose in Buildroot,
so here you are. Note that I am using out-of-tree build mode, like this:

It appears to be explicitly linking against absolute path /lib/libpam.so

Any help is greatly appreciated. I cannot use the newer versions of
Buildroot because of this.

[Buildroot] systemd: build failure against pam on arm

[Waldemar Brodkorb]

Hi,

check config.log where pam_misc is added. May be configure has a bug and detects your host pam under certain conditions.

best regards

Hi Waldemar,

Thank you for looking into this-

Seems like it.

Here is the full log:

Is there a copy of libpam_misc.so somewhere in your buildroot
directory?

I cannot reproduce the problem with your defconfig and br git
master.
I disabled ccache. Could you try without ccache?
Isn't --disable-pam used when you did not enable linux-pam?

[Buildroot] systemd: build failure against pam on arm

[Christian Stewart]

Hi Waldemar,

There are no extra pam files in my Buildroot tree - before building I
ensure this with a "git clean -xfd" and I've searched the tree as well.

Waldemar Brodkorb <wbx@openadk.org> writes:

It may be something specific to Gentoo? The environment looks clean, so
I don't know how Gentoo would affect it, but there's one difference.

BR2_COMPILER_PARANOID_UNSAFE_PATH is enabled, shouldn't this catch it?

Note, I'm using an external build - 

 $ cd buildroot-src/
 $ make O=/home/paralin/buildroot defconfig
 $ cd /home/paralin/buildroot
 $ make clean
 $ make defconfig BR2_DEFCONFIG=$(pwd)/defconfig
 $ make all

Systemd wants to find libpam, if it is not there it seems to
fallback to your native libpam.

You should always run "make clean && make" if you make any
changes to your .config.

Clearly, then, it is not finding the "./target/usr/lib/libpam_misc.so"
in "out-of-tree" build.

I can confirm now that even in-tree builds result in the same thing:

It must be something with how libpam is discovered that is only
triggered when on a system with a libpam.so layout like Gentoo's.

Any ideas how to go about fixing this?

I believe it is an issue how gcc is calling the linker.
In my case I see following:
libsystemd-shared.la -lpam -lpam_misc
-L/home/wbx/buildroot/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib
-lkmod

So the linker does not get -L before -lpam -lpam_misc pointing to
the sysroot. 

If you start gcc with verbose linker output you see:
./output/host/bin/arm-buildroot-linux-gnueabihf-gcc -Wl,-verbose

The included linker script has:
SEARCH_DIR("=/home/wbx/buildroot/output/host/arm-buildroot-linux-gnueabihf/lib");
SEARCH_DIR("=/usr/local/lib"); SEARCH_DIR("=/lib");
SEARCH_DIR("=/usr/lib");

In my case on Debian libpam.so is not in the search dirs, but in
ls /lib/x86_64-linux-gnu/libpam.so.0*
/lib/x86_64-linux-gnu/libpam.so.0
/lib/x86_64-linux-gnu/libpam.so.0.83.1
wbx at helium:~/buildroot$ lsb_release -a
No LSB modules are available.
Distributor ID: Debian
Description:    Debian GNU/Linux 8.9 (jessie)
Release:        8.9
Codename:       jessie

In you case the linker finds libpam.so in /lib and try to use it.

To verify my analyzation you can add -L<sysrootpathofyourbr> into:
systemd/Makefile
PAM_LIBS =
-L/home/paralin/buildroot/pi3/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib
-lpam -lpam_misc

Like in KMOD_LIBS. Then just continue the build with make V=1 and
see if it succeeds.

As systemd is switching completely to meson buildsystem a
upstreamable patch is not possible.

Did the build, after cleaning, again. After encountering the error, I modified the Makefile as you say:

PAM_LIBS = -L/home/paralin/buildroot/output/host/arm-buildroot-linux-gnueabihf/sysroot/usr/lib -lpam -lpam_misc

And tried to continue the build. I got the same error. I also tried
doing a "make clean" inside the systemd build directory and deleting the
build and configure stamps to get it to re-configure after the Makefile
change, that too did not work.

Note that I am using an in-tree build here.

Hopefully some kind of short-term fix is possible in Buildroot or at
least a patch I can apply locally?

There is a mixup of /home/paralin/buildroot and
/home/paralin/Documents... .

Can you use a clean clone and use intree until we found the problem?

Can you do rm -rf output/build/systemd* && make V=1 &>log
And sent me the log and the systemd build directory for post-mortem
analysis.

Sorry I believe you entered the world of libtool hell.

For the hardcore buildroot hackers, if you create a symlink in /lib
pointing to libpam.so / libpam_misc.so you can reproduce the issue.

By the way, I couldn't reproduce the issue with OpenADK.
Unfortunately I can't point to a specific patch. 
I always pass -Wl,-rpath-link -Wl,$(STAGING_DIR)/usr/lib in
LDFLAGS and I always remove any .la files from staging directory.

I do not patch the package provided ltmain.sh/libtool stuff like
Buildroot, but I always use libtool 2.4.6 with a small patch 
like this when autoreconfing a package:
+++ libtool-2.4.6/m4/libtool.m4
-  _LT_TAGVAR(hardcode_automatic, $1)=no
+  _LT_TAGVAR(hardcode_automatic, $1)=yes
 
So sorry, I can't help you out of the hell.

best regards
 Waldemar

So there is a bug in libtool / Buildroot after all, when dealing with
/lib/libpam.so. I was previously able to bisect it down to a commit
upgrading the default Linux headers version, but I can't imagine this is
related.

My libtool knowledge is lacking... Is there a work-around I can apply to
force Buildroot to use these LDFLAGS? I could edit the autotools infra I
suppose, but this seems like a real hack.

If I try to change this in libtool in Buildroot:

checking whether the C compiler works... no
configure: error: in `/home/buildroot/skiff/workspaces/pi3/build/host-libtool-2.4.6':
configure: error: C compiler cannot create executables

I'm guessing I did it wrong? :)

It appears that this bug is fixed in the latest release (2018.02 rc2).

Thanks!

Sure, a nice side effect of the switch to meson by upstream, which eliminates
libtool ;)
