|Subject:||New BSD licensed debugger|

As one or two of you know, I've been working recently on writing a new debugger, primarily for the FreeBSD platform. For various reasons, I've been writing it in a relatively obscure C-like language called D (see http://www.digitalmars.com/d/1.0/index.html for more details including a free download of a FreeBSD D compiler.
So far, I have a pretty useful (if a little raw at the edges) command line debugger which supports ELF, Dwarf debugging information and (currently) 32 bit FreeBSD and Linux. The engine includes parsing and evaluation of arbitrary C expressions along with the usual debugging tools such as breakpoints, source code listing, single-step etc. All the code is new and BSD licensed. Currently, the thing supports userland debugging of i386 targets via ptrace and post-mortem core file debugging of same. I'll be adding amd64 support real soon (TM) and maybe support for GDB's remote debugging protocol later.
If anyone is interested in taking a look at a 'Technology Preview',
I've put up a git repository at http://people.freebsd.org/~dfr/
ngdb.git. To build it you need to install 'omake' from /usr/ports/
devel/omake and you will need a D compiler. There are three options
there - DMD which you can download from
http://www.digitalmars.com/d/download.html is free, closed source and works pretty well. GDC is a D front end to GCC and you can find it in ports - it works well enough but hasn't been updated for ages. Personally, I use LDC which is a D front end to LLVM but that doesn't build out-of-the box (I have a private hacked version of LDC and some associated libraries).
Have fun with it and don't complain too much if it doesn't build/ breaks/eats your homework etc.
