Eclipse indexer unable to find `std` or the first C++ include in files (IEP-1123) about idf-eclipse-plugin

Thanks @kolipakakondal. I'm not sure what went wrong the first time I tried it, but the F3 is working for me now.

[tap] [tap] [tap]... is this thing on? :D
Did I report this to the wrong project?

Hi @mbratch This is a clangd thing!.

I have configured query driver to /Users/kondal/.espressif/tools/xtensa-esp32-elf/esp-12.2.0_20230208/**/xtensa-esp32-elf-* to resolve this. Probably, we can automate these things going forward.

Please check more details here.
https://releases.llvm.org/10.0.0/tools/clang/tools/extra/docs/clangd/Configuration.html#query-driver

Clangd makes use of clang behind the scenes, so it might fail to detect your standard library or built-in headers if your project is making use of a custom toolchain. That is quite common in hardware-related projects, especially for the ones making use of gcc (e.g. ARM’s arm-none-eabi-gcc).

You can specify your driver as a list of globs or full paths, then clangd will execute drivers and fetch necessary include paths to compile your code.

For example if you have your compilers at:
/path/to/my-custom/toolchain1/arm-none-eabi-gcc,
/path/to/my-custom/toolchain2/arm-none-eabi-g++,
/path/to/my-custom2/toolchain/arm-none-eabi-g++,
you can provide clangd with –query-driver=/path/to/my-custom/**/arm-none-eabi* to enable execution of any binary that has a name starting with arm-none-eabi and under /path/to/my-custom/. This won’t allow execution of the last compiler.

FInally, I also don't see any context menu commands for "Open declaration". The other indexer supported it. Is that feature unavailable with the clangd indexer?

Open declaration menu is not available in the editor yet, but you can access this by pressing F3 or Ctrl+Click (I'm on macOS)

Thanks much @kolipakakondal. Unfortunately, under Windows F3 and Ctrl-Click did not do anything.
I raised my issue in the clangd/clangd project on github.

[kolipakakondal]

Hi @mbratch I have verified now on Windows, it seems to be F3 and Ctrl+Click are working fine for me. However, I see editor syntax colors are not shown, will look into this.

As this can be resolved by setting the query driver path in the CDT LSP preferences, closing this issue. If you see any other issues, please report us back. thank you.
