Parsing compilation error/warning not possible.

Parsing compilation error/warning not possible.

[william.a.george]

Hi.
I'm using Emacs on WindowsXP.
I make compilations through emacs with an own written Makefile. The
compilation result is presented on a new buffer. It should be possible
to click on the error or warning message to go directly to the
corresponding line in the file where the error is.
But I can't make it happen. I have read a little bit about this, and
what I could find is something about (compilation-error-regexp-alist)
that should fix this in someway.
Can anyone tell me how this should be done?

Thanks in advance

William George.

Generally you do M-x compile
Then enter the command to make the program, eg "make"
Then you can select the errors one at a time by pressing C-x `

This will only work if your compiler emits messages in a format
understood by Emacs compile-mode.

Thanks for your response.
The compilation part is OK. The problem is that it is not possible to
select the errors in any way. Not by C-x or clicking mouse 2 button or
any other way.
The question is if my compiler is emitting messages in a format that is
understood by emacs compile-mode, as you said.
How can I make the compile-mode to understand my compiler messages?

Hi again.
I wanted to show the syntax for errors and warnings generated by my
compiler:
terminal.c:
  5946: 	while ( (*buf_p != ':') && (*buf_p != CR) && (*buf_p != '\0')
)
E  42: syntax error, expecting statement
  5997: }
W  68: function "GetIntelHex": parameter "stream" not used
W 183: variable 'content_p' possibly uninitialized
total errors: 1, warnings: 2

Maybe this can help in case emacs doesn't understand the compilers
generated errors/warnings.

I don't think it does.  There is a standard in the GNU coding standards
for errors, what you've showed me doesn't follow it.

You can though write your own compilation-parse-errors, or more simply
customize compilation-error-regexp-alist to recognise what you need.

Hi Again.
That is exactly what I wanted to know. How do tailor my own
compilation-parse-errors.
It would be nice if you could give me some hints or examples... I'm a
beginner when it comes to emacs and lisp.
Thanks.
