Hi all,
Have a look at the meta-mono layer:
https://github.com/KokoFitClub/meta-mono/tree/master/recipes-mono/libgdiplus
I found some time to look at the qa_staging failure I've been seeing
when trying to build this recipe. I think I have
a solution so for those like me coming up the OpenEmbedded recipe curve,
here's some feedback for Google.
The libgdiplus recipe (above) uses autotools, one of the outputs of
which seems to be a package configuration file (libgdiplus.pc)
There seems to be an issue that in some cases the .pc file references
paths on the build system, due to the output of the pkg-config
tool and seemingly these paths need to be fixed up to reference the
target instead (or at least, not the host staging directory).
From what I can tell the function package_qa_check_staged() in
openembedded/classes/insane.bbclass is trying to determine
if this problem exists in the .pc files and if so flag it up, which is
why I see:
NOTE: package libgdiplus-2.10-r0: task do_qa_staging: Started
ERROR: QA Issue with staging: libgdiplus.pc failed sanity test (tmpdir)
in path
/data_drive/openembedded/build/tmp-angstrom_2008_1/sysroots/armv5te-angstrom-linux-gnueabi/usr/lib/pkgconfig
ERROR: QA staging was broken by the package built above
NOTE: package libgdiplus-2.10-r0: task do_qa_staging: Failed
So the key seems to be to correct the contents of the pc file.
If we add the following code to the .bb recipe file Koen links to above,
to execute after package
installation it should cause sed to strip out includes of absolute
paths referencing the staging directory:
do_install_append() {
# fix pkgconfig .pc file
sed -i -e s#I${STAGING_DIR_HOST}#I#g ${D}${libdir}/pkgconfig/*.pc
}
If I go to look at the libgdiplus.pc file in the pkgconfig directory of
the staging tree the resulting output looks
correct for the target (I think) and the build then works.
I think this should be the basis for a fairly generic solution to
pkg-config issues, but I'm working this out as I go
along so if I'm misunderstanding things, any corrections on what's going
on would be appreciated.
Best Regards,
Alex
