yocto

问题 I provide a Yocto SDK to cross-build an application for an embedded target. The application itself is built using CMake. The SDK setup script provides many necessary environment variables (like location of the cross-compiler, sysroot, etc.), which so far was enough to build the application. However, since recently the application has a dependency to the Boost library (through the command find_package(Boost REQUIRED) in the CMakeLists.txt). Now CMake complains that it cannot find the library,

问题 I have a yocto image into which I have included the CUPS package (using IMAGE_INSTALL_append ). While running the OS, I couldn't find the cups file in /etc/init.d . I started cups using cupsd . When I tried accessing the web interface using localhost:631 , I got a not found error . The console shows that it is not able to load resources on any of those URLS: http://localhost:631/cups.css http://localhost:631/ http://localhost:631/favicon.ico The html and related files seem to be listed in the

问题 I want to build the core-image-minimal with yocto and it fails. To set everything up I use the following steps: sudo apt-get install gawk wget git-core diffstat unzip texinfo gcc-multilib build-essential chrpath socat cpio python python3 python3-pip python3-pexpect cmake git clone git://git.yoctoproject.org/poky.git poky.git cd poky.git git checkout -b morty remotes/origin/morty . oe-init-build-env cd .. git clone https://github.com/altera-opensource/meta-altera.git meta-altera cd meta-altera

问题 I have a recipe that installed some NPM packages that worked on an older version of Yocto. After upgrading to sumo, the recipe fails with the following error: installnpmpackages/0.0.1-r0/temp/run.do_compile.7272: npm: not found | WARNING: exit code 127 from a shell command. I tried using the developer shell and NPM does work in that case. The do_compile from the recipe: do_compile() { # Create a working directory mkdir -p ${WORKDIR}/scratch # changing the home directory to the working

问题 I need to build a php package supporting the intl extension with bitbake (http://php.net/manual/en/intl.installation.php). So I created a bbappend: bernardo@bernardo-UX51VZA:~/dev/yocto/meta-steempi$ cat recipes-devtools/php/php_7.%.bbappend DEPENDS += " icu apache2" RDEPENDS_${PN} += " icu apache2" PACKAGECONFIG_append_pn-php = " apache2 icu icu-dev" EXTRA_OECONF += " --with-openssl=${STAGING_DIR_TARGET}${exec_prefix} \ --with-config-file-path=${sysconfdir}/php/apache2-php${PHP_MAJOR_VERSION

问题 I have created an image with yocto for raspberrypi-cm3 architecture with eMMC storage. The generated image are stored in folder tmp/deploy/images/raspberrypi-cm3/ (attached photo showing content of such directory). I have this solution to create a .img to flashed to the eMMC: dd bs=512 count=2880 if=/dev/zero of=raspberry-cm3.img mkfs.msdos raspberry-cm3.img mkdir raspberrypi sudo mount -o loop raspberry-cm3.img raspberrypi cp -r /deploy/images/raspberry-cm3/* raspberrypi sudo umount

问题 I'm making a yocto image which I'm booting from a usb stick using syslinux. There's a lot of boot output that I'd like to hide. From reading the yocto docs it looks like adding a splash screen should hide this. I have added splash to the IMAGE_FEATURES , but the splash screen doesn't appear, and the syslinux boot output is still visible. Any idea what I may be doing wrong? Other suggestions on how to hide that boot output also welcome. 回答1: To add splash screen into the image, in your local

问题 I am using BBB to understand the yocto-project. I am not sure how patching works.

问题 Hej I am playing a bit around with Yocto, a Raspberry Pi and some code I wrote. Now I want that Yocto is building an image including the program I wrote. I like to know how to setup the fetcher to fetch from a local git repro. My setup is simple. The code is in the directory: /home/user/git/myTest I linked the directory into my recipe directory of my Yocto meta-layer. /home/user/poky/meta-test/myApp/myTest Because it is a local git repro, there is the ".git" folder. /home/user/git/myTest/.git
