Why does the index not work and how to make it work?

[PŠirů.1]

In STM32CubeIDE it seems that index don´t work. I tried refresh it, but it didn´t help.

This happens when I import existing project into workspace. We tried it on multiple projects and multiple computers, but so far nothing has solved this problem

Hello @Pavel Širů�?ek​ 

Could you please tell me which STMCubeIDE version did you use.

Please tell me more about the scenario to check the issue.

Best regards,

Hello,

thank you for quick response.

I use Version: 1.2.1

Build: 5190_20200115_1224 (UTC)

When i CTRL + left mouse click a function name, this should switch me to function definition (or define, variable, etc...). This works for functions automatically generated from CubeMX. (For example function HAL_GPIO_WritePin works as expected.) But it doesn't work for functions written by myself. IDE throws a error Could not find symbol "function_name" in index. In Attolic, this was working well.

Best regards,

Pavel

Hello @Pavel Širů�?ek​ 

Are your files physically inside the project or linked in from external drive?

Have you tried right-clicking on the project and Indexer --> Re-build?

Index can go broken if you modify/add files outside Eclipse awareness, for example with another external editor...

or Networked / Shared drive?

Hello,

Files are on the same drive but in different location than folder with .project.

Yes, i tried re-build the indexer.

Im adding files by simply copy+pasting them to folders. Is this the problem?

Thank you,

Pavel

Hello @Pavel Širů�?ek​ 

Could you please provide us the structure (in text form is fine, for example C:/MyProjects/MyProject) for the project and for the additional files creates that experiences the error when CTRL + clicking them? Also a screenshot of the Project Explorer view might be helpful.

Best regards,

Hello.

I finally solved this problem.

Here's how for everyone with the same issue:

1) Go to Project->Properties.

2) Search for indexer.

3) Set to this setting:

4) Rebuild index.

I don´t know, what setting is responsible for fixing this issue, but everything is working now, and this is what is important for me.

Thank you all for help.

Best Regards,

Pavel
