emacs, jumping to relative file locations in compiler output.

emacs, jumping to relative file locations in compiler output.

[glen stark]

In the company I'm working for, the build system is set up to cd in 
various directories, and the call make.    When a compiler error is 
returned, it is of the form:

In file included from ../../../../include/whatever.h:33:0

emacs is then unable to determine where to look for the file in question.

Changing out build system is big project, but I'd like to be able to jump 
around to compiler errors in emacs.  In practice I know what path I 
should substitute for "../../../../"

Is there someway I can tell emacs to regex substitute a fixed path for a 
string of the form "../../"?

Is there an alternative solution to my problem (that doesn't mean 
modifying the build system :) ).

Many thanks,

Glen

Sorry, I have a follow up:

After reading more on the subject, I think the path is not the issue.  We 
are outputing "Entering X" and "Leaving x" messages, so I guess emacs 
should be able to handle this.

  The problem might be that the string with the error looks like this:  
EE=../../../../include/Check.h: In function 'Bool check::isNull(UShort)':

If I look at plain old g++ output, I don't see the EE.  So perhaps this 
is the problem?

You can configure regexps to scan the compiler output.
