Does “Update index immediately after every file-save” mean every time I do a file-save operation the indexer is kept updated?


I have the following case where the index does NOT seem to be updated correctly.


Given the following header file contents:


#ifndef SAMPLE_H_

#define SAMPLE_H_


int h_function();

#endif /* SAMPLE_H_ */


And the following source file contents:


//#include "Sample.h"

int main(void) {

      return function() * EXIT_SUCCESS;


int h_function() {

      return 55;



1.-When just open the project and I do a F3 over h_function it takes me no where which makes sense because the header that contains the function prototype is commented out. 

2.-If I uncomment the header Sample.h and I save the F3 over h_function starts working taking me to the h_function prototype so far so good.


3.-But if I comment again the line where I have the #include “Sample.h”, F3 over h_function still works taking me to the prototype so the index seems to have OLD data.

The index is still up to date. Try to comment out int h_function(); instead and see what happens . F3 doesn't need an explicit include to find declaration of h_function. This behavior is particularly important for Add Include.


4.-Nevertheless if rebuild the index (index->Rebuild) I get back the behavior when I just opened the project (step 1).


Could you explain why this happens please? Am I missing something?

By default header files are indexed only if they are included by a source file. You can change this behavior in  Window->Preferences->C/C++->Indexer->Index unused headers. If a header file was indexed once, it will be reindexed on any subsequent change regardless of whether it's still included by a source file or not.


Thanks in advance,
