[yocto] gcc LIBRARY_PATH sstate-cache issue

Wed Oct 21 05:10:52 PDT 2015

Hi Paul ,
Thanks for your answer. Martin pointed me to a patch I will try later on.

I changed the subject

My versions:
 * openembedded-core:

    lib/oe/package_manager: support exclusion from complementary glob process by regex

    Sometimes you do not want certain packages to be installed when
    installing complementary packages, e.g. when using dev-pkgs in
    IMAGE_FEATURES you may not want to install all packages from a
    particular multilib. This introduces a new PACKAGE_EXCLUDE_COMPLEMENTARY
    variable to allow specifying regexes to match packages to exclude.

    rsyslog: fix name of syslogd ua group

    All the other syslogd implementations use 'syslogd' as update alternatives
    group name. So rsyslogd should use this too.

My situation is I have two machines:
* machineA
* machineB: inherits from machine B (only PREFERRED_VERSION for libxml2 added)

two images:
* imageA
* imageB: inherits from image A

I have one build directory for each machine:
* build-machineA
* build-machineB (only new packages added), two of the package are shared libraries : libA and libB. libA is linked to libB. libB depends on libA. libA and libB are cmake recipes

First I build the imageA in build-machineA for machineA

In the build-machineB directory I build imageB for machineB. Moreover I point SSTATE_DIR or SSTATE_MIRRORS of build-machineB/conf/local.conf to build-machineA's sstate-cache directory.

libA is built with success but libB's do_compile fails:

/.../build-machineB$ bitbake libB

At this moment I had to find why ld cannot find libA.so in sysroots so I launched a devshell on libB. In the devshell I cd-ed to the B dir of libB and run the cross-gcc command with the verbose "-v" option.

/.../build-machineB$

I will only show you the interesting part of the
result.
[...]

LIBRARY_PATH=/.../build-machineB/tmp-glibc/sysroots/i686-linux/usr/bin/arm-opensdk-linux-gnueabi/../../lib/arm-opensdk-linux-gnueabi/gcc/arm-opensdk-linux-gnueabi/4.9.1/:/.../build-machineB/tmp-glibc/sysroots/i686-linux/usr/bin/arm-opensdk-linux-gnueabi/../../lib/arm-opensdk-linux-gnueabi/gcc/:/.../build-machineA/tmp-glibc/sysroots/machineA/lib/:/.../build-machineA/tmp-glibc/sysroots/machineA/usr/lib/arm-opensdk-linux-gnueabi/4.9.1//.../build-machineA/tmp-glibc/sysroots/machineA/usr/lib/

 [...]

The symptom is here. Instead of
‘/.../build-machineA/tmp-glibc/sysroots/machineA/usr/lib/’ it should be
‘/.../build-machineB//tmp-glibc/sysroots/machineB/usr/lib/’

I couldn’t find
in libB’s recipe (and included bbclasses) where LIBRARY_PATH is set so I guess it comes from elswhere.

My guess is that
there is a problem in cross-gcc recipe and somewhere the
<sysroots-target>/usr/lib path is hardcoded in sstate-cache. When
recompilling for a different build bitbake use this cache that is polluted by
this hardcoded path.

Note: I have the
same problem if I do same build type (machine, builddir name) but different
locations. 

The meta layer of machineB/imageB has a override of gcc 4.9 which consists only on:
EXTRA_OECONF_GCC_FLOAT = "${@get_gcc_float_setting(bb, d)}"

I had some problem two while changing the version the PREFERRED_VERSION of a recipe in local.conf. When recompiling bitbake don't redo do_unpack so configure/compile/install, one of them fails to find file in S directory. I had to run cleanall on this package before doing a full bitbake.

I hop I have been clear in my explanation of the situation.

Kind Regards,
