bitbake

问题 If I have a tarball, helloworld.tar.gz in a local directory, say /home/user/tarballs/, how can I make my bitbake recipe fetch from that directory? my helloworld.bb is SECTION = "examples" LICENSE = "Proprietary" LIC_FILES_CHKSUM = "file://COPYING; md5=1b1b8016e15e07a2fec59623ebf12345" SRC_URI = "file://helloworld.tar.gz" but when I bitbake, I get the below warning message: WARNING: Unable to get checksum for helloworld SRC_URI entry helloworld.tar.gz: file could not be found I read something

问题 I am attempting to write a recipe that would simple copy two files (MyfileA , MyfileB) to a specific directory when the overall image is built. This is what my directory structure looks like: MyDir/MyRecipe.bb MyDir/files/MyfileA MyDir/files/MyfileB I would like the two files to be copied to a folder in home (which would not exist initially hence the directories should be created)The folder lets say is called "Testfolder" This is what my bitbake file looks like DESCRIPTION = "Testing Bitbake

问题 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

问题 Hi this is my layer tree ├── conf │ └── layer.conf ├── COPYING.MIT ├── README └── recipes-hello ├── helloworld │ ├── helloworld-0.1 │ │ ├── helloworld.c │ │ ├── helloworld.patch │ │ └── newhelloworld.c │ └── helloworld_0.1.bb ├── message │ ├── message-0.1 │ │ └── message.txt │ └── message_0.1.bb └── service ├── service-0.1 │ ├── test_systemd.service │ └── test_systemd.sh └── service_0.1.bb Here test_systemd.service is the service file which have to invoke test_systemd.sh, which I am trying to

问题 In Yocto-based Embedded Linux distributions, I am really interested in finding the complete list of packages/recipes/kernel modules from each dependent layers that will be built and installed to an image file before executing the image building recipe such as: bitbake my-image-minimal Is there a way to achieve this? Any guidance in this regard is appreciated. Thanks in advance. 回答1: Yes, like this On old Bitbake versions: bitbake -g <image> && cat pn-depends.dot | grep -v -e '-native' \ |

问题 Introduction I have a do_install task in a BitBake recipe which I've written for a driver where I execute a custom install script. The task fails because the installation script cannot find kernel source header files within <the image rootfs>/usr/src/kernel . This script runs fine on the generated OS. What's Happening Here's the relevant part of my recipe: SRC_URI += "file://${TOPDIR}/example" DEPENDS += " virtual/kernel linux-libc-headers " do_install () { ( cd ${TOPDIR}/example/Install ; .

问题 I created a new layer over an existing Yocto git for my company project. In this layer I added a few external autotools based libraries. A few applications need to link against this libraries and the application projects are all cmake based. Taking one of this libraries (e.g. libcoap) I could easily find some FindCoAP.cmake to add to my library recipe. Now if I was running on PC, it would simply be a matter of placing this FindCoAP.cmake file in cmake 's ${CMAKE_ROOT}/Modules dir, but how

问题 During a bitbake <image> execution, 3 errors are generated and the building process stopped. Here the last lines of the output: | ERROR: Function failed: do_compile (log file is located at /local/STM32MP15-Ecosystem-v1.0.0/Distribution-Package/openstlinux-4.19-thud-mp1-19-02-20/build-openstlinuxeglfs-stm32mp1/tmp-glibc/work/cortexa7t2hf-neon-vfpv4-openstlinux_eglfs-linux-gnueabi/qtwebkit/5.11.2+gitAUTOINC+beaeeb9988-r0/temp/log.do_compile.26600) ERROR: Task (/local/STM32MP15-Ecosystem-v1.0.0

问题 Looks like I am facing a trivial issue, but I am not able to figure out anything. I was trying to bitbake the raspberry pi image and due to bad internet connection, it failed. Now when I retried to bitbake again, it gives me the below error. fatal: Refusing to fetch into current branch refs/heads/master of non-bare repository I understand that, this is because my git repository is no longer bare. After searching a lot on the internet, I found only one solution. Running the below command will

问题 I have a recipe that needs to know the version string/information of another recipe. Basically I want to expand the PV variable of a different recipe. What would be the easiest way to do this? I was thinking maybe there is a bb python function I can use in my recipe to parse the other recipe and find it's PV. 回答1: Easily, you can't. Can you explain what you actually need to do? 来源： https://stackoverflow.com/questions/56794981/how-can-i-reference-find-the-pv-of-one-recipe-in-another-recipe-in
