Note
Sister PRs:
This brings the
compilation_dbfunctionality to panda, similar to what we already have in openpilot, which helps with IDE integration and code navigation.This feature was originally introduced in openpilot via commaai/openpilot#19533 by @adeebshihadeh.
Previously, the behavior in panda required the
--compile-dbflag to generatecompile_commands.json. We've now improved this:What's changed
compile_commands.jsonis now always generated—no need to pass a flag.Behavior
Standalone Build
When building the panda project on its own, a
compile_commands.jsonwill be created in thepanda/folder containing only panda-related entries.Submodule in openpilot
When panda is built as a submodule of openpilot, its entries will be added automatically to the top-level
compile_commands.jsonin the openpilot root directory. This is achieved by configuring the build environment inpanda/SConscript.This ensures that both IDEs and code analysis tools work seamlessly across the full openpilot + panda codebase.
