Changes in comparison to v6: - Fix findigs: https://lists.openembedded.org/g/openembedded-core/message/188995 - Major refactoring to split IDE specific parts into separate files - Use bindir for gdbserver - Remove pontless warning for debuginfod - Simplified searching for debug symbols - Added a new patch that makes the behavior of image-combined-dbg.bbclass the default behavior of rootfs-dbg. I think this solves a whole bunch of problems not only for GDB but also for all the other tools that need the debug symbols. - Dropped the workaround for the pseudo breakage with sources in tree After a cleanup and improving the script to better replicate what bitbake does I was no longer able to reproduce the issue. - Improve the default behavior for not yet supported build tools. devtool build and devtool deploy-target are called. - Improve the tests: - Start Qemu only once (it's expensive) - Test also the ide=none - Improve documentation about the no recipe mode (to docs mailing list) - Details and bug fixes
According to https://www.yoctoproject.org/community/yocto-project-engineering-request-for-quotation/ one of the proposed areas for development of the Yocto project is "VSCode IDE Integration - New developer tooling". One aspect of this larger topic is helping application developers configure the IDE to work on a recipe's source code using Yocto's eSDK. This patchset provides a new devtool plugin (devtool ide) that does this fully automatically for recipes inheriting the cmake or the meson bbclass. Support for more programming languages and build tools may be added in the future. Let's start with a brief introduction of how it looks like from a user's perspective. Reference setup --------------- $ . oe-init-build-env Add the following layers to bblayers.conf file: - meta - meta-poky - meta-yocto-bsp - meta-selftest Add the following to the local.conf IMAGE_GEN_DEBUGFS = "1" IMAGE_FEATURES += "ssh-server-dropbear debug-tweaks" IMAGE_INSTALL:append = "\ cmake-example-ptest \ meson-example-ptest \ gdbserver \ " Working on a recipe ------------------- Note for those who "hate cmake with passion": Replace cmake by meson in the following commands. 1. Add the recipe which should be modified to the workspace $ devtool modify cmake-example 2. Build the eSDK. This provides all the host tools as well as an image which can be used on the target device. Since everything is built with one bitbake command also all the debug symbols are expected to be consistent. $ devtool ide cmake-example core-image-minimal 3. Install the image on the target device or simply use Qemu $ runqemu 4. Start VSCode $ code "$BUILDDIR/workspace/sources/cmake-example" 5. Work in VSCode, after installing the proposed plugins Ctrl + Shift + p, cmake Select Configure Preset Ctrl + Shift + p, cmake Build 6. Execute the unit tests on the host works with Qemu even for cross compiled test executables. Ctrl + Shift + p, cmake Test 7. Remote debugging with GDB Ctrl + Shift + p, Run Task --> install && deploy-target cmake-example F5 (Debug configuration might be selected before) 8. Work on the recipes and call bitbake again to get the SDK updated. Building the application by calling cmake (from the IDE) or by calling bitbake or by calling devtool build is expected to produce the exact same results. To make that possible, the devtool ide plugin is designed to configure the IDE to call cmake with the exact same configuration as used by bitbake when building the recipe. Unlike the eSDK, the goal here is clearly that there is no longer a separation between the SDK and the application development process. Regardless of which tool is called, the same source files are edited and the same o-files are generated and re-used. Working with a SDK without a recipe ----------------------------------- If devtool ide is called for a recipe named none or meta-ide-support the eSDK with its generic environment file gets generated. In case of using VSCode and cmake in addition to the well known environment file a cmake-kit https://vector-of-bool.github.io/docs/vscode-cmake-tools/kits.html is added to the User-Local Kits. This allows to work with cmake calling the cross-toolchain out of VSCode or a shell with the environment file sourced. Design ------ The goal of this implementation is to create a configuration for VSCode (or other IDEs) that allows to work on the code of a recipe completely independent from bitbake. bitbake is only called if the configuration or the whole SDK has to be regenerated. But bitbake should not need to be called while working in the IDE. This has two major advantages over calling devtool build from the IDE: - The IDE provides plugins for integration with cmake, for example. These features are usable, which would not be the case if bitbake or devtool are called from within the IDE. - It is much faster. Supporting other IDEs --------------------- Focus is currently VSCode. But a paramter "--ide=none" is already supported. With this paramter passed, no VSCode specific config files are generated. Instead, simple scripts are generated, which should be suitable for integration with other IDEs. Testing ------- Reasonable but not yet complete test coverage is provided by: $ oe-selftest -r devtool.DevtoolIdeTests What's next? ------------ - Support for more build-tools and programming languages - Support for more IDEs Known bugs ---------- - IntelliSense with meson does not work. meson and ninja generate a compile_commands.json which requires to have the compiler in the PATH. (cmake generates the same file with absolute path.)
