Please excuse my lack of knowledge and incorrect use of terminology. I
am looking to include irdadump in my build image within Yocto.
I modified the
/poky/meta/recipes-connectivity/irda-utils/irda-utils_0.9.18.bb file to
include irdadump in the list of targets to be built.
INITSCRIPT_NAME = "irattach"
INITSCRIPT_PARAMS = "defaults 20"
TARGETS ??= "irattach irdaping irdadump"
do_compile () {
for t in ${TARGETS}; do
oe_runmake -C $t
done
}
However the bitbake process fails which comes down to the dependency of
pkg-config and glib 2.0 required for idradump.
I did a quick search online and noticed that there was a separate .bb
file for irdadump:
http://cgit.openembedded.org/openembedded/plain/recipes/irda-utils/
I tried to replicate this however was still faced with compiling issues.
Could anyone give me a helping hand on including irdadump to my
irda-utils package?
Thank you
To add irda-utils to your build image, just add IMAGE_INSTALL_append in your conf/local.conf file.Next time when you will run Bitbake,it will include irda-utlis package in your build image.
IMAGE_INSTALL_append = " irda-utils"

What changes should make to enable dlt-system.
In build folder dlt-system application is not generating.
Manually by using command: cmake -D with dlt-system=ON it will generate but I need to generate while building please look at recipie image
Your recipe supports dlt-system via PACKAGECONFIG.
In order to activate that flags in the compilation process, you just need to add dlt-system to PACKAGECONFIG in .bb or .bbappend file to the recipe:
PACKAGECONFIG_append = " dlt-system"
If you want to add it from local.conf:
PACKAGECONFIG_pn-name_append = " dlt-system"
Just change name with your recipe name.
This will add -DWITH_DLT_SYSTEM=ON to EXTRA_OECMAKE which is used in do_configure of the cmake class.
I new to Yocto so there are probably some mistakes and misunderstanding that I've had, I appreciate if you can help.
So, I want to add a new package (tar file) to my custom image.
I have followed steps and steps in manual and some online instructions. While running: "bitbake mylayer", the layer is built fine but I got this error while building the image, here is the log file:

This may mean that the package is missing, has been obsoleted, or

And here is mylayer.bb:

LICENSE = "CLOSE"
FILESEXTRAPATHS_prepend := "${THISDIR}/files:"
SRC_URI += "file://mypackage.tar"
Also, I have included the package in conf/local.conf:
IMAGE_INSTALL_append += " mylayer"
So beside trying to figure out how to solve this problem, I also have some questions:
I have read some example of .bb, and they mentioned about LIC_FILES_CHKSUM. The mypackage.tar.gz is a package to install a platform for the device and I don't know much about the source code, so I don't know if it is necessary to include the license? Or how to know that this package need license to install?
In some answer I found online, there is one saying that I need to include PACKAGE_CLASSES ?= "package_deb" (they want to install the .deb file), so probably in my case I will need PACKAGE_CLASSES ?= "package.tar" right? I have tried to change variable, but it still not successful.
The mypackage.tar includes some deb files. If I could not install mypackage.tar, can I instead install these .deb files? Can I put it all in mylayer.bb?
Thank you in advanced, I have tried to study much documents as I could but I get so confused and there is huge amount of information to digest.
First, before answering your questions
Let me mention some best practices advice for you:
Rename the recipe to some significant name related to you compressed package.
Naming the recipe to mylayer confuses Yocto users, because there is the term layer also.
Regarding you recipe:
There is no need for FILESEXTRAPATHS because the recipe path is added automatically to Yocto paths.
FILESEXTRAPATHS it is required for .bbappend files.
You need to override the do_install task function, it does nothing by default.
do_install is the first essential task to make sure that your sources are included in the final image.
Beside that, when specifying a compressed source file into SRC_URI, yocto automatically decompresses it.
This is mentioned here.
So, here what your recipe should look like:
SUMMARY = ""
LICENSE = "CLOSED"
# Prevent Yocto from decompressing the file
SRC_URI = "file://mypackage.tar;unpack=0"
do_install(){
# Create the opt folder into the final image, ${D} is ${WORKDIR}/image
install -d ${D}/opt
# Copy the compressed file there; You can change permissions as you want
install -m 0755 ${WORKDIR}/mypackage.tar ${D}/opt
}
# Very important to specify what you installed in (do_install)
FILES_${PN} = "/opt/*"
Now, when you run IMAGE_INSTALL_append += " mylayer" your file will be installed.
Regarding your questions:
You mentioned that your compressed file contains .deb files, I assume that no license checksum is needed. Also, I understand that you may wanted to point to SRC_URI[md5sum] or other checksums for the full package. That is also not needed for local files, it is used to check for the integrity of online sources.
PACKAGE_CLASSES as mentioned here, is used by the system to know in what type the data should be packaged. By the data I mean the data that you installed with do_install. That data get packaged for according to your PACKAGE_CLASSES variable, for example, to deb file. And that is used, along side with all other recipes packages, to build the final rootfs.
Yes, if you are installing the tar file into the image and then unpack it to install all deb files, for example, with dpkg. You can use the bin_package class to do that, now the recipe must be changed for that reason:
Decompress the tar file and provide the deb files in the local files folder.
Add all deb files to SRC_URI
Inherit the bin_package class
Specify the files to be packaged.
Your recipe should look like this:
SUMMARY = ""
LICENSE = "CLOSED"
SRC_URI = "file://deb_file1.deb \
file://deb_file2.deb"
# No need to `do_install` , it is invoked by the (bin_package) class
FILES_${PN} = ""
Important:
About FILES_${PN}, you need to add all what the deb installed into the image folder
Example, if your deb file installs this:
/usr/bin/hello
/etc/hello.cfg
Specify them:
FILES_${PN} = "/usr/bin/*"
FILES_${PN} += "/etc/*"
Use * so if other deb files install files into the same folder as others it will include all.
This follows on from
How do I strip and objcopy a built .so file in the Yocto bitbake compile step?
This leads back to considerable background information.
As mentioned in the previous question, I am seeking to build OCA, which I have
as a non-Yocto makefile-based project, in Yocto. The project, which builds
fine outside of Yocto, and even in Yocto, is quite complex. The issue is that it
is not cross-compiling for my target, which is aarch64 armv8-a. It is building
successfully, but for my host machine, which is x86-64. Then Yocto sensibly
refuses to package it, saying "Unable to recognise the format of the input
file".
I changed the compile flags in my makefile to -march=armv8-a, but got the error
"cc1plus: error: bad value ('armv8-a') for '-march=' switch" which seems to
mean that I can't use the host's installed gcc for cross-compiling, but rather a
cross-compiler is needed. I previously custom-added two additional layers, a
sample helloworld and mDNS (see previous questions for lots of background), and
they all cross-compiled fine, so I know that Yocto is basically set up to do it.
What is the method to get the cross-compilation to happen? Do I need to do a lot
of pervasive changes to my project's makefile system? It may not ever have been
designed with Yocto in mind.
I am looking into this: "cross-compile library recipe in yocto":
cross-compile library recipe in yocto
which seems to have some relevant information. Edit: it was only standard stuff that I had seen before; nothing about how cross-compilation gets invoked instead of the host machine's gcc.
Edit: My updated recipe, with the FILES_${PN} added and make changed to
oe_runmake.
DESCRIPTION = "OCA"
PRIORITY = "optional"
SECTION = "protocols"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
SRC_URI = "file://oca-1.2.7"
S = "${WORKDIR}/oca-1.2.7/Src"
# Need to override S because BitBake expects the source to be in a dir called
# oca-1.2.7 in the work dir, but it's actually additionally under Src/.
# Need a do_compile, since OCA has a makefile with a non-standard name,
# makefileOCA. Also needs non-standard flags, -f and linuxRelease.
do_compile() {
export CAP_HOME="${WORKDIR}/oca-1.2.7"
oe_runmake -f makefileOCA linuxRelease
}
do_install() {
install -d ${D}${libdir}
cp ../Obj/linuxApp/Release/OcaProtoController.so ${D}${libdir}/OcaProtoController.so
chmod 0755 ${D}${libdir}/OcaProtoController.so
}
FILES_${PN} += "${libdir}/OcaProtoController.so"
Edit: I found some info:
https://www.yoctoproject.org/docs/1.8.1/adt-manual/adt-manual.html
https://www.yoctoproject.org/docs/1.8.1/adt-manual/adt-manual.html#setting-up-the-cross-development-environment
I commented-out the setting of CC and LD in makeOCA.inc.
I did the cleaning actions of deleting the tmp folder from my build-wayland
build dir, and did "bitbake -c cleansstate oca". Then I did "time bitbake oca".
Now it looks like it is using the cross compiler.
The first error I got now is:
~/Yocto/imx-yocto-bsp/build-wayland/tmp/work/aarch64-poky-linux/oca/1.2.7-r0/oca-1.2.7/Obj/linuxApp/Release/OcaAgentProxies.a
aarch64-poky-linux-ld: cannot find crus: No such file or directory
So this is the next question: Can you tell me what "crus" means in "LDFLAGS = crus $#"?
I have been using Yocto to create Linux builds for an ARM board.
I had been cross compiling add on applications manually. Now we are in a place where we would like a nice integrated build so I started adding custom recipes to yocto.
I have been struggling with the ARM build (a x86 build with the same code seems fine).
Even a basic 'hello world' pretty much cut and paste from the development manual does not work (http://www.yoctoproject.org/docs/current/dev-manual/dev-manual.html#new-recipe-writing-a-new-recipe)
Here is the recipe:
SUMMARY = "Simple helloworld application"
SECTION = "examples"
LICENSE = "MIT"
LIC_FILES_CHKSUM = "file://${COMMON_LICENSE_DIR}/MIT;md5=0835ade698e0bcf8506ecda2f7b4f302"
RPROVIDES_${PN} = "helloworld"
FILES_${PN} += "${bindir}"
SRC_URI = "file://helloworld.c"
S = "${WORKDIR}"
do_compile() {
${CC} helloworld.c -o helloworld ${LDFLAGS}
}
do_install() {
install -d ${D}${bindir}
install -m 0755 helloworld ${D}${bindir}
}
Here is the error:
ERROR: helloworld not found in the base feeds (smarc_samx6i cortexa9t2hf-vfp-neon-mx6qdl cortexa9hf-vfp-neon-mx6qdl cortexa9t2hf-vfp-neon cortexa9t2hf-vfp cortexa9hf-vfp-neon cortexa9hf-vfp armv7at2hf-vfp-neon armv7ahf-vfp-neon armv7at2hf-vfp armv7ahf-vfp armv6thf-vfp armv6hf-vfp armv5tehf-vfp armv5ehf-vfp armv5thf-vfp armv5hf-vfp noarch any all).
ERROR: Function failed: do_rootfs
Any suggestions as to what would be causing this error?
The package does build properly; the problem seems to be isolated to finding it for the rootfs.
Thanks!
EDIT:
I have a solution that seems to work, although it is not ideal long term.
Changing the package name under IMAGE_INSTALL from helloworld to helloworld-0.0.1 resolves the issue. Obviously I would rather not hard code the version of each package in the top level recipe and other packages do not require this, so hopefully there is another solution.
EDIT 2:
Renaming the recipe and removing the version string also resolves the issue. Once again, this does not seem ideal long term.
OK, after some further testing I discovered this was a naming issue with the recipe.
It was named helloworld-0.0.1.bb (the same format with the other recipes I had put together driving me to try this simple test).
If anyone else encounters this simply replacing the '-' with a '_' resolves this.
1.Rename your recipe name e.g hello-0.1.bb to hello_0.1.bb
2.Add below line at last only:
FILES_${PN} = "${bindir}/*"
Abvoe line helps you copy your binary to rootfs.
I have created a Yocto autotools project in Eclipse (based on a Hello World project).
I wanted to separate my code into a number of libs and then link them in a form of static libs (.a) to my project.
Now I have one app and a number of static libs. However, no matter what I try I can't get my code to compile. Each separate lib compiles and produces a .a file, but my app doesn't.
After searching the web I have a possible solution - add a direct link to my static libs:
MyApp_CPPFLAGS="-I$LOCATION"
MyApp_LDADD="/home/xxx/workspace/MyApp/Encoding2/Debug/libEncoding2.a"
This is my Makefile.am file, where libEncoding2.a exist in that path.
The error I get is:
make[2]: *** No rule to make target `"/home/xxx/workspace/MyApp/Encoding2/Debug/libEncoding2.a"', needed by `MyApp'. Stop.
I already built the lib so I am not sure why a make try is even needed.
Any help will be appreciated.
Because you use static library in your recipes, you can make a soft link to the library in your project source folder, i.e., hello-world-0.1, using following command to link to your static library
ln -s /home/xxx/workspace/MyApp/Encoding2/Debug/libEncoding2.a
and then edit your bb file, hello-world_0.1.bb, adding the source path to your URL
SRC_URI = " \
file://libEncoding2.a \
file://hello-world.c \
"
and in the do_compile block, using follow command to compile your project
do_compile() {
${CC} hello-world.c libEncoding.a -o hello-world
}
do_install() {
install -d ${D}${bindir}/Hello
install -m 0755 enet ${D}${bindir}/Hello
}
After you bitbake your project
bitbake hello-world
and run mkefidisk.sh, you can find the hello-world in /usr/bin/Hello/hello-world. Hope this hint can help you.
BTW, I am not familiar with autotools, I just use make to bitbake the recipes. And your static library should also be created in Yocto not in Eclipse I think. So I think your path for the static library maybe not correct, it should locate in ~/yocto/build/tmp/... or some where like this. In my case, it was located in ln -s ~/yocto/build/tmp/sysroots/intel-corei7-64/usr/lib/libEncoding.a depends on your target environment.
Depending on whether you're using libtool or not, you should have either a noinst_LTLIBRARIES or noinst_LIBRARIES list of targets, respectively. This should only include the name of your library (libEncoding2.la or libEncoding2.a.)
You should never use a full path for this, and you should not quote Make variables, so what you were looking for is
MyApp_CPPFLAGS = -I$LOCATION
MyApp_LDADD = libEncoding2.la # or .a
And that would work.
But on the other hand it seems like you should take some time to understand how autotools work, as it might not be what you're looking for. With a grain of salt you can take my Autotools Mythbuster as a starting point.
