CMake + CubeIDE indexing issue: Compilation Database Parser error

[pmndt]

 

Hi everyone,

I’ve successfully created and imported a CMake-based project for the STM32F777NIH in STM32CubeIDE 2.0.0. The project builds and compiles without any issues.

However, the IDE cannot properly resolve headers, some macros, variables, and some struct definitions. To fix this, I enabled:

set(CMAKE_EXPORT_COMPILE_COMMANDS TRUE)

in my top-level CMakeLists.txt, which correctly generates a compile_commands.json.

In CubeIDE, I also enabled C/C++ General → Preprocessor Include Paths, Macros etc. → Providers → Compilation Database Parser, and pointed it to the generated compile_commands.json (AN5952).

But CubeIDE shows:

Invalid build parser

And the error log contains:

“Compilation database parser does not have a build command parser configured.”

So it seems CubeIDE refuses to use the compilation database to resolve include paths, even though the file exists and is valid.

Is there any known workaround to allow STM32CubeIDE to consume compile_commands.json for indexing?
Or any other reliable way to fix header/struct auto-completion and indexing issues when working with CMake-based STM32 projects?

Thanks in advance!

 

Edit-1:

I have also attached the .ioc file in case it helps.

Hello @pmndt 

I am currently checking this behavior. I will get back to you asap

Hello @pmndt 

First you need to tick the option " CDT GCC Build Output Parser " as shown in the following screenshot

Then go back to "Compilation Database Parser" and in Build Parser tab : select "CDT GCC Build Output Parser" as shown below 

then apply and close.

Thank you very much! This solved the indexing issue.

Hello,

I followed your instructions, but the indexer is still not working.

Even after rebuilding the index I get no entries here:

And also syntax highlighting fails (macro STM32F303xE is set):

Any ideas?
