I'm trying to get DBG to work for the first time ever for me, I have a x86_64 system (Xeon) and was able to build the dbg php module, and phpinfo() reports it as loaded, but no matter what client I try (I've tried both PHPEclipse and Protoeditor (KDE DBG Client), nothing seems to work. All I ever get is things seeming to hang for forever.

Now, I'd love to try the "official" command line client, but I can't get it to build on my machine, but is there anyone out there who can verify that the dbg module works on an x86_64 machine? Any ideas about something I could be doing wrong?

I just installed dbg on my x86 machine (32bit) and all of the clients that I tried on my 64bit machine worked there, whereas they didn't work on the 64bit one.

Is there anything else I can do to verify my question of whether or not dbg runs on 64bit platforms?

1. run buildconf to create new configure script
2. run configure script with --with-dbg-trace=/tmp/dbg-cli.log
3. proceed with make
then run dbg-cli, try to run commands in it and let me know if it fails
or not. If it is, dbg-cli.log may help with finding the reason for failure.

Just got dbg-cli to build.

If I follow the instructions to have it be in listening mode, it segfaults as soon as I issue the "set mapurlroot" command ("set mapurlroot http://localhost/" is what I do).

If I just do "listen 7869" it doesn't wait (even if I give it a timeout), it opens the socket, and closes it right away.

Output when trying to listen:
dbg>listen 10001
ListenerBase::startJIT
dbh_create_listen_socket(, 0)
socket=3
[DBG] startJIT->1
Waiting for debug session (press Ctrl-C to stop)...
ListenerBase::stopJIT
dbh_close_socket(3)

Show me backtrace please.
run: gdb ./dbg-cli [options for dbg-cli]
then run "run" from the gdb prompt, then invoke set mapurlroot and as soon as you get segfault, run bt to see the backtrace.

Got the same thing after specifying -O0

Seems to have worked, I can use the cli debugger
