I actually compiled with gcc-2.95.3!  The kernel was built with 2.96!

Did not try that!  Will do again to verify my build.

I did not install the libxml at this server.  I guess that is the problem.

What happened is that I ran configure with --prefix=xxx/quickfix-1.4.0 When I
tried to build the java stuff, it failed.  I then added the above (which was the
target of the "make install" runs...  The tree is actually
/quickfix/examples/executor/java.  I think that since I gave a prefix, it should
have added it to the Makefile?

No problem. Thanks.

Let me have a play with the examples.  But to start, what is the threading
model.  Basically, an app derives from a base class and implements an interface
which gets called on different fix events.  How many threads (if any) are making
these callbacks?  Is there a thread per Fix Session or a pool?  What is the
synchronization scheme?  Do the callbacks have to be re-entrant?  Is there a way
to connect to the application to issue admin commands (ie the app listens on a
command port to which I can connect to and get a list of available admin
commands such as "list sessions", "kill session", "connect", or whatever?  I saw
something about Admins but did not get a chance to read further.  

Can my app have its own pool of threads for handling events?  Can the app
receive (and process) another fix message (from a different session) while I am
handling a callback, ie, more than one thread...?

Anyways, just a question or two? ;-)

Is there a way to download all the archives for "homework"?

Thanks
David
