Description Stuart McDonald CLA 2010-07-05 04:44:02 EDT 
Just started using Eclipse on a Fedora machine, it's based on version 3.4.2 with CDT 5.0.2.200903191301 and if I have a single source with
[CODE]#include <boost/gil/extension/io/png_dynamic_io.hpp>[/CODE]
The indexer hangs; fast or full index. Also tried skip all references.

If it replace the #include with the actual file contents then it doesn't hang.

In general versions before CDT 6.0 don't work well for code with c++ templates. You need to upgrade CDT. Your specific example is a performance issue. It takes 19 minutes to index the file plus its headers. In CDT 6.0.2 or 7.0 the same code is indexed in 47 sec. 

When you paste the content of the header into the source file, the indexer no longer picks up some of the includes, which makes it fast but incomplete.


Here are the statistics:
