I’m trying to complete the boost::signal tutorial at http://www.boost.org/doc/libs/1_47_0/doc/html/signals/tutorial.html#id2850736

However Eclipse CDT shows parsing errors with whichever syntax I use

I have

#include <boost/signals.hpp>

Preferred syntax

boost::signal<void (float, float)> sig;    
sig.connect(&print_sum);

Invalid template arguments at signal

Method ‘connect’ could not be resolved

Portable syntax

boost::signal2<float, float, float> sig;
sig.connect(&print_sum);

Method ‘connect’ could not be resolved

Symbol ‘signal2’ could not be resolved

I use eclipse 3.7

    It seems to be a CDT issue. Have you updated your eclipse version lately? There is a discussion on that topic in the eclipse forum going on:

    http://www.eclipse.org/forums/index.php/t/216821/

    Maybe it gives you some inspiration on how to work around that problem.

    EDIT: As a temporary work around, you can disable certain code analysis features and markers. To do so, go to Window->Preferences->”C/C++”->”Code Analysis” and disable some or all problems. I have disabled all, since it will still highlight errors found during the compilation and I will not be confused by falsely declared problems.
