Boost types cannot be resolved [message #1703186]

I know this is a problem many people had in the past, but I am not able to solve it.

I am using, for instance, boost::recursive_mutex in both .hpp and .cpp files of my code. I am including #include <boost/thread/locks.hpp> in the .hpp file and it does not complain. However, in the cpp file a red square appears next to the scroll bar saying " boost::recursive_mutex::scoped_lock type could not be resolved". However the code compiles properly.

Analogously, in the cpp I am using algo boost::bind and including #include <boost/bind.hpp>. In this case it complains about unresolved inclusion and the 'same type could not be resolved message'.

I have added /usr/include/boost to paths and symbols and the project is generated from CMake.

Any help is appreciated!

I'm no expert by my guess is the index needs rebuilt (right click on the project in the project explorer/navigator then select Index->Rebuild) and if that doesn't fix it then the include paths may need to be added to the project under "project->properties->C/C++ General->Processor include paths, macros, etc." or "project->propertie->C/C++ General->Paths and Symbols".

You could also explicitly place the definitions in the marked error code and surround it with

#ifdef __CDT_PARSER__
:
:
#endif

which will hide if from the compiler. Sometimes this appears to be the only way.

You might also look at how the indexer has been configured. There's too much detail to go into but I found that, for me, the cache limits were too small. The indexer options are under Window->Preferences->Indexer.

Disabling Code Analysis might work too but I would find that unpalatable.
