Yocto rust recipe also produces -native output that needs packaging - yocto

I tried this approach on hardknott but I couldn't get it to work recipe also produces -native output that needs packaging
It is a rust recipe that generates an x86_64 app which I would like to package the right way in sdk, so that it can be used.
I can separate the main package to -native-bin, and I see it in the recipe-sysroot, but I can't get it to populate the recipe-sysroot of the workdir of the file when building the -native-helper recipe. And I suspect the reason is that I get an error that the main recipe for x86_64 can't be found?
ERROR: Manifest xxxxxx.populate_sysroot not found in vs_imx8mp cortexa53 armv8a-crc armv8a aarch64 allarch x86_64_x86_64-nativesdk (variant '')?
So any helpful information would be appreciated!

Hacked like this:
Recipe.bb:
do_install_append() {
# Set permision without run flag so that it doesn't fail on checks
chmod 644 ${D}/usr/bin/#RECIPE#-compiler
}
# #RECIPE# generates a compiler during the target generation step
#separate this to the -native-bin package, and skip the ARCH checks
#also in the image file for stations_sdk move the app to right dir and add execute flag
PACKAGES_prepend = "${PN}-native-bin "
PROVIDES_prepend = "${PN}-native-bin "
INSANE_SKIP_${PN}-native-bin = "arch"
FILES_${PN}-native-bin = "/usr/bin/#RECIPE#-compiler"
SYSROOT_DIRS += "/"
Image.bb:
# #RECIPE# produces a compiler that is produced as a part of the target generation
#so we use the recipe and hack it to supply the -compiler as part of the
#host binaries
TOOLCHAIN_TARGET_TASK_append = " #RECIPE#-native-bin"
do_fix_#RECIPE#() {
mv ${SDK_OUTPUT}/${SDKTARGETSYSROOT}/usr/bin/#RECIPE#-compiler ${SDK_OUTPUT}/${SDKPATHNATIVE}/usr/bin/#RECIPE#-compiler
chmod 755 ${SDK_OUTPUT}/${SDKPATHNATIVE}/usr/bin/#RECIPE#-compiler
}
SDK_POSTPROCESS_COMMAND_prepend = "do_fix_#RECIPE#; "
This produces at the end the binary in the right directory

Why doesn't my recipe re-build successfully when I'm offline?

I have a recipe that looks basically like this :
SUMMARY = "SomeLibrary"
LICENSE = "Apache-2.0"
LIC_FILES_CHKSUM = "file://LICENSE;md5=3b83ef96387f14655fc854ddc3c6bd57"
SRC_URI += "git://gitlab.com/some_library/some-library.git;protocol=https;nobranch=1"
SRCREV = "${PV}"
S = "${WORKDIR}/git"
inherit autotools pkgconfig
It builds successfully with bitbake some-library, and I can see there is a git2/gitlab.com.some_library.some-library.git/ directory and a git2/gitlab.com.some_library.some-library.git.done file in my downloads folder (the one DL_DIR point to).
My understanding is that if I then immediately run bitbake -c cleansstate some-library && bitbake some-library, given that there is no change in the recipe, bitbake shouldn't need to download anything (it already has everything it needs). In practice, if I turn off my network connection or add BB_NO_NETWORK="1" to my local.conf, I get the following error :
Initialising tasks: 100% |################################################################| Time: 0:00:01

Summary: There was 1 ERROR message shown, returning a non-zero exit code.
Why is that ? How do other recipes avoid this pitfall ? (when I build my image, this recipe seems to be the only one trying to fetch things from the network, which suggests to me that I'm doing something wrong here)
EDIT :
What really puzzles me is that bitbakes seems to behave differently with recipes other than my own. For example, the recipe for can-utils located at meta-openembedded/meta-oe/recipes-extended/socketcan/can-utils_git.bb looks like this:
SUMMARY = "Linux CAN network development utilities"
LICENSE = "GPLv2 & BSD-3-Clause"
LIC_FILES_CHKSUM = "file://include/linux/can.h;endline=44;md5=a9e1169c6c9a114a61329e99f86fdd31"
DEPENDS = "libsocketcan"
SRC_URI = "git://github.com/linux-can/${BPN}.git;protocol=https;branch=master"
SRCREV = "da65fdfe0d1986625ee00af0b56ae17ec132e700"
PV = "2020.02.04"
S = "${WORKDIR}/git"
inherit autotools pkgconfig
which is very similar, but when I set BB_NO_NETWORK="1" in my local.conf and run bitbake -c cleansstate can-utils && bitbake can-utils I get Tasks Summary: Attempted 842 tasks of which 822 didn't need to be rerun and all succeeded.
This works for me:
After configuring the project, add the following lines to build/conf/site.conf file:
# Build offline
SOURCE_MIRROR_URL ?= "file:///path/to/oe-downloads"
INHERIT += " own-mirrors"
BB_GENERATE_MIRROR_TARBALLS = "1"
BB_NO_NETWORK = "1"
After that, it might be necessary to build project once when online.
After every re-configuration (different build options) the site.conf is overwritten, so I created a script to add these lines after re-configuration.
I believe I found the issue.
If I replace ${PV} (which was equal to v2.3.0 here) by the hash associated to that tag, then the issue stops happening.
If I interpret this correctly, it means that bitbake is able to tell if SRCREV is a hash or a tag, and that if it is a tag then do_fetch will always run git ls-remote to make sure that the tag has not been moved.

Yocto & wpa_supplicant - installing libwpa_client.so

I'm working with this Yocto/ Bitbake recipe for wpa_supplicant (v2.9) which is a bbappend for this recipe. I had significant difficulties getting the associated library (libwpa_client.so) included in the install process during my Yocto/ Poky build. Eventually I created my own bbappend which contained:
# Force build of library libwpa_client.so
do_configure_append() {
echo 'CONFIG_BUILD_WPA_CLIENT_SO=y' >> wpa_supplicant/.config
}
# Avoid QA errors:
INSANE_SKIP_${PN} += " ldflags"
INHIBIT_PACKAGE_STRIP = "1"
INHIBIT_SYSROOT_STRIP = "1"
SOLIBS = ".so"
FILES_SOLIBSDEV = ""
# Force install of libwpa_client.so
do_install_append(){
install -d ${D}${libdir}
install -m 0644 ${S}/wpa_supplicant/libwpa_client.so ${D}${libdir}
}
Using the config option CONFIG_BUILD_WPA_CLIENT_SO=y failed to install the library so thats why I went with the do_install_append() method. I find it hard to believe this hasn't come up before for others so I think I'm missing something, I can't find similar hacks/ patches.
Can't someone point out if I'm missing something obvious?? There's a patch file for v2.10 which may be associated with this issue, but I think it's more an issue with the Makefile as the library file was successfully built for v2.9, just not populated to the final image.
If this isn't a waste of half a day perhaps this will help others.

How can I get "HelloWorld - BitBake Style" working on a newer version of Yocto?

In the book "Embedded Linux Systems with the Yocto Project", Chapter 4 contains a sample called "HelloWorld - BitBake style". I encountered a bunch of problems trying to get the old example working against the "Sumo" release 2.5.
If you're like me, the first error you encountered following the book's instructions was that you copied across bitbake.conf and got:
ERROR: ParseError at /tmp/bbhello/conf/bitbake.conf:749: Could not include required file conf/abi_version.conf
And after copying over abi_version.conf as well, you kept finding more and more cross-connected files that needed to be moved, and then some relative-path errors after that... Is there a better way?
Here's a series of steps which can allow you to bitbake nano based on the book's instructions.
Unless otherwise specified, these samples and instructions are all based on the online copy of the book's code-samples. While convenient for copy-pasting, the online resource is not totally consistent with the printed copy, and contains at least one extra bug.
Initial workspace setup
This guide assumes that you're working with Yocto release 2.5 ("sumo"), installed into /tmp/poky, and that the build environment will go into /tmp/bbhello. If you don't the Poky tools+libraries already, the easiest way is to clone it with:
$ git clone -b sumo git://git.yoctoproject.org/poky.git /tmp/poky
Then you can initialize the workspace with:
$ source /tmp/poky/oe-init-build-env /tmp/bbhello/
If you start a new terminal window, you'll need to repeat the previous command which will get get your shell environment set up again, but it should not replace any of the files created inside the workspace from the first time.
Wiring up the defaults
The oe-init-build-env script should have just created these files for you:
bbhello/conf/local.conf
bbhello/conf/templateconf.cfg
bbhello/conf/bblayers.conf
Keep these, they supersede some of the book-instructions, meaning that you should not create or have the files:
bbhello/classes/base.bbclass
bbhello/conf/bitbake.conf
Similarly, do not overwrite bbhello/conf/bblayers.conf with the book's sample. Instead, edit it to add a single line pointing to your own meta-hello folder, ex:
BBLAYERS ?= " \
${TOPDIR}/meta-hello \
/tmp/poky/meta \
/tmp/poky/meta-poky \
/tmp/poky/meta-yocto-bsp \
"
Creating the layer and recipe
Go ahead and create the following files from the book-samples:
meta-hello/conf/layer.conf
meta-hello/recipes-editor/nano/nano.bb
We'll edit these files gradually as we hit errors.
Can't find recipe error
The error:
ERROR: BBFILE_PATTERN_hello not defined
It is caused by the book-website's bbhello/meta-hello/conf/layer.conf being internally inconsistent. It uses the collection-name "hello" but on the next two lines uses _test suffixes. Just change them to _hello to match:
# Set layer search pattern and priority
BBFILE_COLLECTIONS += "hello"
BBFILE_PATTERN_hello := "^${LAYERDIR}/"
BBFILE_PRIORITY_hello = "5"
Interestingly, this error is not present in the printed copy of the book.
No license error
The error:
ERROR: /tmp/bbhello/meta-hello/recipes-editor/nano/nano.bb: This recipe does not have the LICENSE field set (nano)
ERROR: Failed to parse recipe: /tmp/bbhello/meta-hello/recipes-editor/nano/nano.bb
Can be fixed by adding a license setting with one of the values that bitbake recognizes. In this case, add a line onto nano.bb of:
LICENSE="GPLv3"
Recipe parse error
ERROR: ExpansionError during parsing /tmp/bbhello/meta-hello/recipes-editor/nano/nano.bb
[...]
bb.data_smart.ExpansionError: Failure expanding variable PV_MAJOR, expression was ${#bb.data.getVar('PV',d,1).split('.')[0]} which triggered exception AttributeError: module 'bb.data' has no attribute 'getVar'
This is fixed by updating the special python commands being used in the recipe, because #bb.data was deprecated and is now removed. Instead, replace it with #d, ex:
PV_MAJOR = "${#d.getVar('PV',d,1).split('.')[0]}"
PV_MINOR = "${#d.getVar('PV',d,1).split('.')[1]}"
License checksum failure
ERROR: nano-2.2.6-r0 do_populate_lic: QA Issue: nano: Recipe file fetches files and does not have license file information (LIC_FILES_CHKSUM) [license-checksum]
This can be fixed by adding a directive to the recipe telling it what license-info-containing file to grab, and what checksum we expect it to have.
We can follow the way the recipe generates the SRC_URI, and modify it slightly to point at the COPYING file in the same web-directory. Add this line to nano.bb:
LIC_FILES_CHKSUM = "${SITE}/v${PV_MAJOR}.${PV_MINOR}/COPYING;md5=f27defe1e96c2e1ecd4e0c9be8967949"
The MD5 checksum in this case came from manually downloading and inspecting the matching file.
Done!
Now bitbake nano ought to work, and when it is complete you should see it built nano:
/tmp/bbhello $ find ./tmp/deploy/ -name "*nano*.rpm*"
./tmp/deploy/rpm/i586/nano-dbg-2.2.6-r0.i586.rpm
./tmp/deploy/rpm/i586/nano-dev-2.2.6-r0.i586.rpm
I have recently worked on that hands-on hello world project. As far as I am concerned, I think that the source code in the book contains some bugs. Below there is a list of suggested fixes:
Inheriting native class
In fact, when you build with bitbake that you got from poky, it builds only for the target, unless you mention in your recipe that you are building for the host machine (native). You can do the latter by adding this line at the end of your recipe:
inherit native
Adding license information
It is worth mentioning that the variable LICENSE is important to be set in any recipe, otherwise bitbake rises an error. In our case, we try to build the version 2.2.6 of the nano editor, its current license is GPLv3, hence it should be mentioned as follow:
LICENSE = "GPLv3"
Using os.system calls
As the book states, you cannot dereference metadata directly from a python function. Which means it is mandatory to access metadata through the d dictionary. Bellow, there is a suggestion for the do_unpack python function, you can use its concept to code the next tasks (do_configure, do_compile):
python do_unpack() {
workdir = d.getVar("WORKDIR", True)
dl_dir = d.getVar("DL_DIR", True)
p = d.getVar("P", True)
tarball_name = os.path.join(dl_dir, p+".tar.gz")
bb.plain("Unpacking tarball")
os.system("tar -x -C " + workdir + " -f " + tarball_name)
bb.plain("tarball unpacked successfully")
}
Launching the nano editor
After successfully building your nano editor package, you can find your nano executable in the following directory in case you are using Ubuntu (arch x86_64):
./tmp/work/x86_64-linux/nano/2.2.6-r0/src/nano
Should you have any comments or questions, Don't hesitate !

Yocto: Install different config files based on MACHINE type or target image

I've got a couple of HW platforms (same cpu, etc.) that require different asound.conf files.
The way that I'm controlling the target platform is via the MACHINE variable and target image (i.e., MACHINE=machine_1 nice bitbake machine-1-bringup-image)
Normally, if just replacing the conf file I'd just create an alsa-state.bbappend and create a do_install_append function to replace it.
However since the different HW platforms require differ conf files I'm unsure how to handle it.
I've tried putting some logic into the append file do_install_append function but it's not working out. It's not always picking up the correct file (like it thinks that nothing has changed so that it uses the previous cached conf?)
Here's an example of one of the append files that I've tried:
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI += " \ file://asound_MACHINE1.conf \
file://asound_MACHINE2.conf \ "
do_install_append() {
echo " alsa-state.bbappend MACHINE: ${MACHINE}"
if [ "${MACHINE}" = "machine_1" ]; then
echo " machine_1"
echo " installing ${WORKDIR}/asound_MACHINE1.conf to ${D}${sysconfdir}/asound.conf"
install -m 644 ${WORKDIR}/asound_MACHINE1.conf {D}${sysconfdir}/asound.conf
else
echo " installing ${WORKDIR}/asound_MACHINE2.conf to ${D}${sysconfdir}/asound.conf"
install -m 644 ${WORKDIR}/asound_MACHINE2.conf ${D}${sysconfdir}/asound.conf
fi
}
I can see the correct echoes in the logs per the logic.
At any rate I don't think that the path I'm going down is the best way to deal with this.
Is there a 'standard' way to have different files installed based on either the target image or MACHINE variable?
do_install_append () {
// install common things here
}
do_install_append_machine-1 () {
// install machine-1 specific things here
}
do_install_append_machine-2 () {
// install machine-2 specific things here
}
The value of MACHINE is automatically added to OVERRIDES, which can be used at the end of a function append to have a MACHINE-specific addition to a function.
Maybe useful: https://www.yoctoproject.org/docs/2.4/mega-manual/mega-manual.html#var-OVERRIDES
You can have configuration files in machine specific directories in your particular case (just a specific configuration file for each machine). OpenEmbedded will fetch the most specific one. The directory structure in your recipe directory will look like:
files/<machine1>/asound.conf
files/<machine2>/asound.conf
And your alsa-state.bbappend will contain just one line (you don't need to change do_install because alsa-state.bb already installs asound.conf):
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
BTW: We are using that setup to have specific asound.state file per machine in our project.
Moreover, OpenEmbedded will detect that SRC_URI contains machine specific file and change the PACKAGE_ARCH accordingly, see: https://www.yoctoproject.org/docs/2.5/mega-manual/mega-manual.html#var-SRC_URI_OVERRIDES_PACKAGE_ARCH
Few more words on machine, distro or arch specific files: OE is trying to fetch the most specific file in file:// fetcher. It searches also in the directories named by distro (e.g files/<distro>/asound.conf) and architecture (e.g. armv7a, arm). It might be useful if you want to have file specific for some set of devices. More information: https://www.yoctoproject.org/docs/2.5/mega-manual/mega-manual.html#var-FILESOVERRIDES and also https://www.yoctoproject.org/docs/2.5/mega-manual/mega-manual.html#best-practices-to-follow-when-creating-layers (section "Place Machine-Specific Files in Machine-Specific Locations")
The above answer by clsulliv worked better than advertised. For future reference below is the append file I used:
FILESEXTRAPATHS_prepend:= "${THISDIR}/${PN}:"
SRC_URI += " \
file://machine1_asound.conf \
file://machine2_asound.conf \
"
do_install_append_machine1() {
echo " machine1"
echo " installing ${WORKDIR}/machine1_asound.conf to ${D}${sysconfdir}/asound.conf"
install -m 644 ${WORKDIR}/machine1_asound.conf ${D}${sysconfdir}/asound.conf
}
do_install_append_machine2() {
echo " machine2"
echo " installing ${WORKDIR}/machine2_asound.conf to ${D}${sysconfdir}/asound.conf"
install -m 644 ${WORKDIR}/machine2_asound.conf ${D}${sysconfdir}/asound.conf
}
Thanks for the help!

How do I add script files to a Raspberry Pi filesystem using a custom Yocto recipe?

I have a working Yocto image for a RaspberryPi3. I want to add 3 script files /etc/ppp/peers/. I would have thought that adding non-compiled files to the root file-system was a fairly generic thing to do but the only examples I can find are using compiled files and inheriting the autotools recipe.
Is there an example of how to add text files or script files to a Yocto root filesystem this somewhere?
Either a How To write up or an existing recipe that takes a set of text files and places them onto the target's rootfs.
I must be missing something because I cannot get the file files onto the system.
I tried using do_deploy, but that puts files into my ../tmp/deploy/images/raspberrypi3/etc/ppp/ which would be helpful for scripts to aid in image deployment. It is not what I want though as the scripts need to be on the target.
Running a do_install() with or without a blank do_compile() has not resulted in things getting onto the target either. Unless there is something about using ${sysconfdir} or ${IMAGE_ROOTFS} or ${S} or ${D} or ${DEPLOYDIR} or ${WORKDIR} which is particular to the Pi. I'd provide an example of my script but having changed it so many times in the last two days there is not much worth of sharing just one iteration.
Anything that resembles the following with;
${IMAGE_ROOTFS} possibly substituted for ${D} or missing
do_install replaced with do_deploy.
There are probably other permutations that I have tried.

FILES_${PN} += "${sysconfdir}/ppp/peers/<provider>-chat-disconnect"
I can find a lot of helloworld.c and automate examples. There must be some basic ones for adding scripts somewhere? My googlefu is very weak, I blame a lingering cold.
You should be using install -m 0755 ${WORKDIR}/<provider>-ppp ${D}${sysconfdir}/ppp/peer in your recipe. Have you added the resulting package to your image recipe? You could look at ${WORKDIR}/packages-split/${PN} to confirm that your files have been properly packaged.
