Re: Emacs 24 semantic C++ completion problem

["Eric M. Ludlam" <ericludlam@gmail.com>]

Hi,

When mysterious problems occur with the smart completion engine, it is 
often a challenge to figure out what is going on. - ie - is there a bug 
in Semantic, a setup issue, etc.

I always recommend using `semantic-analyze-debug-assist', used while 
point is in a location that caused the completion problem. 
Unfortunately, this command doesn't have an autoload cookie in Emacs, so 
you need to first:

M-x load-library RET semantic/analyze/debug RET

to make it available.  Hopefully its advice can help fix any 
configuration issues.  I'll guess you need to create a small EDE project 
to point Semantic to your headers.  Most likely using an example of 
ede-cpp-root project type.

For the 2nd problem you list, that seems more like a bug that may have 
been fixed with the version of CEDET from the CEDET bzr repository. 
There have been a few bug fixes there since CEDET was last merged into 
Emacs.  If setting up EDE fixes the first but not the second, you should 
check w/ the CEDET bzr repository.
