[cdt-dev] Indexer and different build configurations

[Martin.Runge@xxxxxxxxxxxxxxxxx]

Hi all,

I experience some inconsistant behaviour
of the indexer in the following scenario: I have defined two build configurations:


- debug_x86 
- debug_arm

They build the same project with different
toolchains and therefore include header files from different paths. An
example::

std::cerr is defined in 
#include <iostream>

debug_x86  ->  /usr/include/c++/4.8/iostream
debug_arm  ->  /path/to/cross/compiler/include/iostream

I found three different settings for
the CDT indexer, that influence how this is handled:

1) Use the build configuration specified
in the project's indexer settings
   This one is clear and behaves like expected.

2)   Use active build configuration
  2a)  Allow heuristic resolution
of includes 
        The Indexer
asks the user, which of the two header versions to use

  2b) Do not allow heuristic resolution
of includes 
       The indexer
uses the correct header file for both configurations, but it completely
rebuilds the index after each change of the build configuration!

Rebuilding the index every time the
configuration is changed is not feasible IMHO, except for very small projects.

As far as I understood, the index is
something tied to the configuration. If I use several configurations, I
get the same number of indexes. Is there a way to keep them spererate and
just switch between them?

best regards
Martin
