Re[1]: [cedet-semantic] Debugging with semantic-1.4.4

[Eric M. L. <er...@si...>]

You would probably have better luck using the latest cedet beta.  In
that version, the original .by file (replacement of the .bnf) is
stored so that the debugger can find it without having to do the more
complex setup described in 1.4.

In 1.4, your process sounds correct.  The end of a debug session
concludes by showing the BOVINATE buffer.  If the parser thinks there
is nothing to parse, then it would indeed skip debugging, and jump
right to that buffer.

This could happen if there is no parse table, or if the buffer
doesn't lex properly for some reason.  You can do this:

M-: (semantic-lex (point-min) (point-max)) RET

to see if that is doing ok.  (ie, does it think there is one big
comment?)

C-u M-x bovinate RET

will also show if the basics of parsing is working.

If that is the case and the debug is still not working, I have no
idea what else it might be.
