Building an Ada aware gdb

Building an Ada aware gdb

[Duncan Sands]

I see that gdb from CVS has some exciting (for me) files
in it: ada-exp.y, ada-lang.h, ada-tasks.c, ada-valprint.c,
ada-lang.c, ada-lex.l, ada-typeprint.c.  I would like to build
gdb with Ada support... but how?  The only Ada related
configure option seems to be --enable-libada, and that didn't
give me an Ada aware gdb.  Does gdb support Ada now?
If so, how to build it...

Thanks for any help,

Duncan.

Not yet, but we're finally getting close.  At the moment, we are
resolving some issues with hooks we'd like to put into non-Ada sources.
After that, it's mostly a matter of linking in the Ada modules and testing
for regressions on every platform we can get our hands on. 

A couple of warnings: 

1. The current CVS ada-* sources have not been synced with ACT's
development versions.  This fact has nipped me a couple of times now
(including your question), so I should probably update them just so
folks can see them.

2. We are turning on Ada support one piece at a time, because there are
numerous places where ACT's sources have modifications in non-Ada files
that either have to approved for inclusion in public sources or modified
to conform to the public sources.  These places include full breakpoint 
support (source file:line will work out of the box) and tasking (where
the configuration-management situation will always be at the mercy of
threads and their many incarnations).


On the other hand, we should have expression evaluation working pretty
much.
