问题 I am trying to use Yocto with meta-tegra ( https://github.com/madisongh/meta-tegra ) to build a minimal system for the Nvidia Jetson Nano. I need to use CUDA ( current version 10 for Nano ) with OpenCV on this platform. CUDA 10 only support GCC 7, and not GCC 8. GCC 7 has be deprecated and removed from OpenEmbedded Warrior release in favor of GCC 8.3. My error has to do with trying to use GCC 7 with Warrior release of OE: configure: error: cannot compute suffix of object files: cannot compile

问题 I have an autotools-based BitBake recipe which I would like to have binaries installed in /usr/local/bin and libraries installed in /usr/local/lib (instead of /usr/bin and /usr/lib , which are the default target directories). Here's a part of the autotools.bbclass file which I found important. CONFIGUREOPTS = " --build=${BUILD_SYS} \ --host=${HOST_SYS} \ --target=${TARGET_SYS} \ --prefix=${prefix} \ --exec_prefix=${exec_prefix} \ --bindir=${bindir} \ --sbindir=${sbindir} \ --libexecdir=$

问题 I want to add gedit to the the image. But i am not able to find the dependencies of gedit package. How to find the dependencies (DEPENDS) in yocto. 回答1: You can use the following command which opens up a Dependency explorer that displays dependencies on the packages: bitbake -g recipe-name -u depexp or bitbake -g gedit -u depexp ,in your case. On pyro and later use: bitbake -g recipe-name -u taskexp Note: this command needs python-gtk2 installed. 回答2: You can also use Toaster, which is a web

Best practice for building firmware using Yocto

由 僤鯓⒐⒋嵵緔 提交于 2019-12-07 04:53:09
问题 I have a working Yocto build system based on the rocko branch that is generating images for an ARM-based target board. One of the chips on this board is a small ARM-based micro-controller that is separate to the main CPU. It needs to be loaded with a firmware image that I have to build. It would be easy to make a recipe to build this microcontroller firmware. It requires an ARM cross compiler and then some special compiler options to control the code generation (for cortex-m4 + thumb etc).

问题 I wish to add more python modules to my yocto/openembedded project but I am unsure how to? I wish to add flask and its dependencies. 回答1: some python packages having corresponding recipes in the meta folders, like Enum class for example: meta-openembedded/meta-python/recipes-devtools/python/python-enum34_1.1.6.bb unfortunately lot's of useful classes aren't available, but some might be needed for the python application. get used of installing missing packages using pip already on booted

How to add multilanguage support to a Yocto build?

由 柔情痞子 提交于 2019-12-06 09:46:20
I'm trying to add multilanguage support to a Yocto build. Reading the official documentation I've found that the build options that controls locale settings are: GLIBC_GENERATE_LOCALES IMAGE_LINGUAS Link: http://www.yoctoproject.org/docs/1.8/mega-manual/mega-manual.html#var-GLIBC_GENERATE_LOCALES After a build with the following options: GLIBC_GENERATE_LOCALES="en_GB.UTF-8 en_US.UTF-8" IMAGE_LINGUAS?="en-gb" if I ask to "localectl" the list of available locales, nothing is displayed (command: localectl list-locales). Another bit of info, the output of the "locale" command is: LANG= LC_CTYPE=
