The ide-sdk command bootstraps the SDK from the bitbake environment
before the IDE configuration is generated. In the case of the eSDK
installer, the bootstrapping is performed during the installation of
the eSDK installer. Running the ide-sdk plugin from an eSDK installer
based setup would require skipping the bootstrapping and probably taking
some other differences into account when generating the IDE
configurations.
This would be possible. But it will probably never be implemented, as
running devtool ide-sdk directly from the bitbake environment is much
more flexible.
Also, some of the recent improvements that have made it into the core
have the potential to make the eSDK installer obsolete at some point in
the future:
- bitbake-layers create-layers-setup replicates the layers
- bitbake-config-build replicates the build configuration
- The new sstate mirror features replicate the sstate
- bblock locks the sstate more flexible than the eSDK installer
- devtool ide-sdk bootstraps the SDK directly from the bitbake
environment. The same environment-setup... file is provided with
--mode=shared.
The devtool modify based workflow is supported since always by devtool
and also the default --mode of devtool ide-sdk.
These functions essentially cover what the eSDK installer does without
a need for the current implementation of the eSDK installer and the
populate_sdk_ext, which is hard to maintain and takes a lot of time to
build.
This means that instead of making the ide-sdk plugin compatible with the
eSDK installer, we should rather replace the current implementation of
the eSDK installer and populate_sdk_ext with an implementation that can
replicate a normal bitbake environment in a convenient way where the
ide-sdk plugin also just works without additional complexity.

The debug_build_config function was never called. Compiling with debug
optimized compiler flags was not working. Even with the
--debug-build-config flag set, the build configuration from the recipe
was used.
The devtool ide-sdk --debug-build-config approach didn't work very well
anyway. The problem is that changing the bbappend file doesn't work
while bitbake uses the bbappend file. As a workaround, it would be
possible to parse the recipe, get DEBUG_BUILD and the path to the append
file, exit tinfoil, change the bbappend file, reopen tinfoil and do what
ide-sdk is supposed to do. Such an implementation would be complicated
and slow.
Therefore, the code that was originally supposed to implement this is
removed from ide-sdk and the new --debug-build function of devtool
modify is used instead. Additionally, a hint should be given on how to
manually add DEBUG_BUILD = '1' to bbappend.
This is compatible with the VSCode Bitbake plug-in, which does not
support this parameter anyway.

Dropping support for S = WORKDIR allows to drop this ugly workaround.
With S = WORKDIR it was possible to refer to a file via oe-local-files
symlink or via direct file path. Ensuring the pseudo database is
consistent for both paths was extra complicated and required this bad
function. Really nice to drop it now!

Improve the previous commit:
- log an error if some assumptions are not true
- Use TARGET_DBGSRC_DIR variable
- Do the same for ide none
Why the additional source mapping is required:
For example the cmake-example recipe refers to sources like this:
./recipe-sysroot-native/usr/bin/x86_64-poky-linux/x86_64-poky-linux-readelf \
-wi image/usr/bin/cmake-example | grep -B1 DW_AT_comp_dir
...
<560> DW_AT_name : (indirect line string, offset: 0x1da):
/usr/src/debug/cmake-example/1.0/oe-local-files/cpp-example.cpp
...
Another example is powertop:
./recipe-sysroot-native/usr/bin/x86_64-poky-linux/x86_64-poky-linux-readelf \
-wi image/usr/sbin/powertop | grep -B1 DW_AT_comp_dir
...
<561> DW_AT_name : (indirect line string, offset: 0x1da):
/usr/src/debug/powertop/2.15/src/devlist.cpp
...
For recipes with local files this works. The oe-local-files folder is
not available in the rootfs-dbg and therefore the sources are first
found in the workspace folder. GDB searches for source files in various
places:
https://sourceware.org/gdb/current/onlinedocs/gdb.html/Source-Path.html
However, for the powertop example the sources opened in the editor are
from the rootfs-dbg instead of from the workspace.
Bitbake calls the compiler with
-fmacro-prefix-map=${S}=${TARGET_DBGSRC_DIR}
where TARGET_DBGSRC_DIR defaults to "/usr/src/debug/${PN}/${PV}".
A source map which maps the recipe specific path from TARGET_DBGSRC_DIR
to the workspace fixes this.
The already existing source map for /usr/src/debug applies for all other
recipes. It finds the sources (read only) in the rootfs-dbg folder.

When launching the debug configuration, the source files from the debug
rootfs were openened in the editor instead of the local workspace files.
We add an exception to properly map them to the file being developed and
compiled by the IDE integration. This also more closely matches what the
user would expect compared to native development.
This is also true for the devtool fallback mode.

The compile_commands.json file output by meson uses the compiler as if
present in the $PATH. However, when using an IDE, the $PATH used by
bitbake is not there.
The vscode-cpptools now allows to define the compilerPath in addition
to replace the one from compile_commands.json.

The generated scripts use the sys.path configuration found inside
bitbake. It can be a different python version than the one used on the
host through the IDE.
For instance, when running the generated script
deploy_target_cmake-example-core2-64 from an eSDK generated on another
machine, I got the following exception:
AssertionError: SRE module mismatch
We need to match the sys.executable to the sys.path.

The new devtool ide plugin provides the eSDK and configures an IDE to
work with the eSDK. In doing so, bitbake should be used to generate the
IDE configuration and update the SDK, but it should no longer play a
role when working on the source code. The work on the source code should
take place exclusively with the IDE, which, for example, calls cmake
directly to compile the code and execute the unit tests from the IDE.
The plugin works for recipes inheriting the cmake or the meson bbclass.
Support for more programming languages and build tools may be added in
the future.
There are various IDEs that can be used for the development of embedded
Linux applications. Therefore, devtool ide-sdk, like devtool itself,
supports plugins to support IDEs.
VSCode is the default IDE for this first implementation. Additionally,
some generic helper scripts can be generated with --ide none instead of
a specific IDE configuration. This can be used for any IDE that
supports calling some scripts.
There are two different modes supported:
- devtool modify mode (default):
devtool ide-sdk configures the IDE to manage the build-tool used by the
recipe (e.g. cmake or meson). The workflow looks like:
$ devtool modify a-recipe
$ devtool ide-sdk a-recipe a-image
$ code "$BUILDDIR/workspace/sources/a-recipe"
Work in VSCode, after installing the proposed plugins
Deploying the artifacts to the target device and running a remote
debugging session is supported as well.
This first implementation still calls bitbake and devtool to copy the
binary artifacts to the target device. In contrast to compiling,
installation and copying must be performed with the file rights of the
target device. The pseudo tool must be used for this. Therefore
bitbake -c install a-recipe && devtool deploy-target a-recipe
are called by the IDE for the deployment. This might be improved later
on.
Executing the unit tests out of the IDE is supported via Qemu user if
the build tool supports that. CMake (if cmake-qemu.bbclass is
inherited) and Meson support Qemu usermode.
- Shared sysroots mode: bootstraps the eSDK with shared sysroots for
all the recipes passed to devtool ide-sdk. This is basically a wrapper
for bitbake meta-ide-support && bitbake build-sysroots. The workflow
looks like:
$ devtool ide-sdk --share-sysroots a-recipe another-recipe
vscode where/the/sources/are
If the IDE and the build tool support it, the IDE gets configured to
offer the cross tool-chain provided by the eSDK. In case of VSCode and
cmake a cmake-kit is generated. This offers to use the cross
tool-chain from the UI of the IDE.
Many thanks to Enguerrand de Ribaucourt for testing and bug fixing.
