Can ddd show gdb version number? How does ddd set gdb multi-thread?

[John Roberts]

Hi,

I'm using ddd 3.2.1 (i386-redhat-linux-gnu) under RedHat 7.2 Linux
on my Pentium IV system.  I'm having a problem running the 02r1
version of gdb (5.2.1).

(1)  Is there a command I can type in the command window to get
     gdb to echo its version?  I want to make sure ddd is running
     the right version of gdb.
     
(2)  When I run gdb stand-alone on my multithreaded application,
     no problem.  But when I try using ddd, I get the following:

It looks to me like ddd is somehow running gdb in a single-threaded
manner for my multi-threaded app.  What is controlling this
in ddd?  Is there something in my environment?

(Curiously if I run ddd on gdb, then use "run my_app" to run my
application from the command window, ddd/gdb seem to behave
correctly with respect to threads.)

Any advice/hints?


Thanks!
