How to get eclipse use the correct Pins_*.h?

wilriker

I have everything for RRF setup in eclipse. It is working. I can compile successfully and get working binaries out of it. There is just one annoying thing that I cannot get to work correctly:

It only looks at Pins.h for the feature flags like SUPPORT_WORKPLACE_COORDINATES or SUPPORT_LASER and all of the others.

In my case I use Duet2_RTOS as the active build configuration and to all I can see it should recognize src/DuetNG/Pins_DuetNG.h but it doesn't.
This leaves me with sometimes hard to navigate code parts where something is enclosed in #ifdef XXX ... #endif and eclipse evaluates XXX to 0 because that's the value in Pins.h but in Pins_DuetNG.h it is redefined to be 1. And it just won't let me navigate code in this case.

What could I check/do about that?

Found it. Although the indexer was enabled in global settings with correct values I had to go to
Project -> Properties -> C/C++ General -> Indexer
and tick Enable project specific settings.

All of the so called project specific settings are absolutely identical to the ones of the global indexer but now it works.

It works for me. What version of Eclipse are you using? I use Version: 2018-09 (4.9.0).

There is a setting in Eclipse to rebuild the index when you switch build configuration, and I have that selected.

@dc42 I am using Version: 2018-12 (4.10.0) but it never worked in any version for me. I rebuilt the index about a million times already. Also it shows the src/DuetNG folder as excluded in the Project Explorer even though it obviously includes it when compiling because it builds the binaries without any issues.

I also tried to add the folder explicitly to
Project Properties -> C/C++ General -> Preprocessor Include Paths, Macros etc. -> CDT User Setting Entries
in all of the available forms. It just does not want to read this file.

Switching build configurations back and forth also did not help. I mean, I can work with it and found my ways around it but it would be nicer not to have to use global search to find things that I cannot jump to because they are inside #ifdef blocks.

I sometimes find that in order to get the correct folders shown, I have to select another configuration, then go back to the one I want.
