Re: [yocto] Files copied to /usr/local during installation get removed misteriously
you are right, it is defined in layers/meta-ked/classes/userfs.bbclass I didn't consider that it could be something added by a custom layer but it is, as you said. I'll have a loot at it.

Re: [yocto] Files copied to /usr/local during installation get removed misteriously
It is in run.do_userfs. I saw that the files where removed while do_image_userfs task was running so I looked at the image logs in temp directory and found it there -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

Re: [yocto] Files copied to /usr/local during installation get removed misteriously
Just in case someone has the same problem, it is the do_userfs function the one
that deletes /usr/local directories and files after copying them to
${image_userfs}:
cp -r
/build/tmp/work/kontron_mx8mm-ked-linux/image-ked-qt/1.0-r0/rootfs${image_userfs_dir}/*
${image_userfs}
rm -rf
/build/tmp/work/kontron_mx8mm-ked-linux/image-ked-qt/1.0-r0/rootfs${image_userfs_dir}/*
I have changed the installation folder to /opt that seems more appropiate
Thanks

[yocto] Files copied to /usr/local during installation get removed misteriously
Hi,
I have a recipe that creates some directories in /usr/local and copies there
some files using do_install:append

When I build the image, I see the folders appear in /usr/local as expected
while creating the rootfs but at some point they are removed and, by the time
the rootfs creation finishes, they are gone.
If I take the ipk package and install it on the embedded device the folders and
files are created correctly so I guess that the recipe is fine but there is
some task during the rootfs creation that deletes all the files in /usr/local
(my folders are not the only ones that are deleted).
Who could be doing that or how can I debug it to find the culprit?
Kind regards,
Javi

Re: [yocto] Missing -lgpiod during linking an application that uses libgpiod
I solved the issue. It turned out to be not a yocto but a Qt problem. The Makefile used to build the application is autogenerated by qmake so you have to include LIBS += -lgpiod in order to add the library in the linking stage. I was looking in the wrong place! Sorry for the noise javi -=-=-=-=-=-=-=-=-=-=-=- Links: You receive all messages sent to this group.

[yocto] Missing -lgpiod during linking an application that uses libgpiod
Hi,
I’m building a Qt application to controls a few GPIOs so, in my recipe, I add
libgpiod to the DEPENDS variable, but even then the –lgpiod is missing in the
linking stage and the build fails with several ‘undefined reference’ errors to
the gpiod functions:

This is my recipe:
SUMMARY = "GPIO QT TEST APPLICATION"
DESCRIPTION = "GPIO user interface build with QT"
LICENSE = "GPLv2"
LIC_FILES_CHKSUM = "
file://${COREBASE}/meta/files/common-licenses/GPL-2.0-only;md5=801f80980d171dd6425610833a22dbe6
(
file://$%7bCOREBASE%7d/meta/files/common-licenses/GPL-2.0-only;md5=801f80980d171dd6425610833a22dbe6
) "
SRC_URI = ""
DEPENDS += "qtbase qtdeclarative qtmultimedia qtwebengine *libgpiod* "
RDEPENDS:${PN} += "qtxmlpatterns qtdeclarative-qmlplugins qtbase-plugins
ttf-dejavu-sans qtquickcontrols qtquickcontrols2 qtfreevirtualkeyboard "
S = "${WORKDIR}"
do_install:append () {
install -d ${D}${bindir}
install -m 0775 qt_testgpio ${D}${bindir}
}
FILES:${PN} += "${bindir}/qt_testgpio"
FILES:${PN} += "/opt/*"
inherit qmake5
What am I missing? Shouldn’t the inclusion of libpgiod library to the DEPENDS
variable result in the addition of –lgpiod to the link command? I tried to add
LDFLAGS:append = “ –lgpiod” but it didn’t solve the problem.
Any help will be appreciated.
Kind regards,
Javi
