Indexer detects wrong include file of two possibilities [message #989026]

Hello.

I'm using Eclipse Juno with CDT 8.1 on Windows.

I'm developing software mainly for a Target microcontroller. But I have the possibility to generate code for a Simulation of the code on a PC.

To separate between 'Target' and 'Simulation' I use two different Output directories:
'Target' = 'bin'
'Simulation' = 'sim'.

Underneath those directories there is a similar tree with a header file of the same name but different content ('Target' or 'Simulation'):

<Project dir>
- bin
-- include
--- generated
---- autoconf.h
:
:
-sim
-- include
--- generated
---- autoconf.h
:

Somewhere in my code there is

#include <generated/autoconf.h>

And here is my problem:

When I 'follow' this include (F3 or Strg-Click), I ALWAYS get the 'autoconf.h' from sim. And therefore the Eclipse Indexer is highlighting for 'sim' and not for 'bin' as I request.

I have already inserted in
<Project Properties> | C/C++ General | Paths and Symbols | Includes | GNU C
the entry

<Project path>/bin/include

What do I have to do to create a Configuration, in which the upper 'F3' brings me to the include of the bin folder???

TIA
Dirk

You should create two build configurations
http://help.eclipse.org/juno/topic/org.eclipse.cdt.doc.user/reference/cdt_u_prop_manage_dialog.htm?cp=11_4_7_0_2_0

Then in Project Properties set the source location for every build config
http://help.eclipse.org/juno/topic/org.eclipse.cdt.doc.user/reference/cdt_u_prop_general_pns_src.htm?cp=11_4_7_0_4_5_4

In C/C++ Project Properties, C/C++ Indexer
http://help.eclipse.org/juno/topic/org.eclipse.cdt.doc.user/reference/cdt_u_prop_general_idx.htm?cp=11_4_7_0_4_3

you can select which build configuration the indexer will use.

Yes . . . I understand that.

This I don't understand.

Here is my project structure (also as attachment):

index.php/fa/12593/0/

'bin' and 'sim' are in the SAME project parallel by the source folders.
The 'Source Location' for BOTH build configs would therefore be 'GV642_Premium_Bosch' !?!?

If the second point above is clear, then I fully understand the last point.

THX for the help.

Sorry . . . but *BUMP*.

At least I would like to know, how/why the Indexer prefers the 'sim' directory over the 'bin' directory?
And how can I change/revert that 'attitude'?

THX in advance.

You can define exclude filters for the source location.
e.g.
Config1
source location GV642_Premium_Bosch
exclude bin

Config2
source location GV642_Premium_Bosch
exclude sim

see

Hello Axel,

first THX for the reply.

I'm sorry, but that didn't work either.
I have excluded 'sim' in 'Source location' and did a 'Rebuild Index'.
Then I have navigated again and I ended again falsely in 'sim'.
This screenshot is the situation directly after the last 'F3':

index.php/fa/12630/0/

Even as 'autoconf.h' is (obviously) excluded, it is highlighted and opened in an editor. Confused

And here are the 'Indexer' settings in the PROJECT:

index.php/fa/12631/0/

Is there the possibility of a bug in CDT?

My only way to get it working properly is to RENAME the 'sim' folder and 'Rebuild Index'.

Did you add sim folder in Project Properties->General->Paths and Symbols->Includes?

Nope.

On the opposite I've even added 'bin' and 'bin\generated' as Includes with no success.

What does it take to get eclipse to index correctly? It doesnt appear able to actually go and look in the right file
header1.h
struct fred{
int a
}fred_t;

header2.h
struct fred{
int b
};

file.c
fred _t*ptr

goes to header2 EVEN THOUGH HEADER2 is NOT EVER INCLUDED IN THE PROJECT but just happens to be in the same tree!

I tried this with a sample HelloWorld project.
Not sure what you were trying to do
but header1.h is declaring a variable named fred_t as struct fred .
It should have a typedef.

In any case, using Photon (4.8.0) and CDT (9.5.2.2018071141),
I get the proper file from an F3
although I get a syntax error without the typedef.

When I hover over fred_t in main.c I get the proper definition.

You don't say which Eclipse and CDT you are using.

I don't think there is any way to stop the Indexer from scanning files in a directory unless the directory is marked as
Excluded (RC dir in Project View --> Resource Configurations --> Exclude from Build ...)
and the Index Source files not included in the build is deselected.
(Project --> Properties --> C/C++ General --> Indexer)

The Indexer doesn't handle multiple definitions nicely though.
This is particularly true of macros.
The test I ran is rather simple.
Perhaps a more complicated one would confuse the Indexer.

header1.h

#ifndef HEADER1_H_
#define HEADER1_H_

typedef struct fred{
	int a;
} fred_t;

#endif /* HEADER1_H_ */

header2.h
I used float so I could tell which was being used when hovering.
I changed the float to int but F3 still goes to the proper header file.
I also tried changing the 'b' to an 'a' and it still worked properly.

#ifndef HEADER2_H_
#define HEADER2_H_

typedef struct fred{
	float b;
} fred_t;

#endif /* HEADER2_H_ */

main.c

#include <stdio.h>
#include <stdlib.h>

#include "header1.h"

int main(void) {
	fred_t * pFred;
	puts("Hello World"); /* prints Hello World */
	return EXIT_SUCCESS;
}
