Justin,

When Session::sendToTarget is called, a SessionNotFound exception is thrown
if you try to send to a session that does not exist.  I suspect you are
sending to a session that is not configured in the QuickFIX config file.
You can verify this by changing some of the code so it does some better
error handling.  In the queryEnterOrder function in Application.cpp for
tradeclient, change this code:

if(queryConfirm("Send order"))
    FIX::Session::sendToTarget(order);

to this

if(queryConfirm("Send order"))
{
    try
    {
      FIX::Session::sendToTarget(order);
    }
    catch( FIX::SessionNotFound& e)
    {
        std::cout << "Session does not exist, cannot send message" <<
std::endl;
    }
}

If this message pops up, you know that the session does not exist.

I am running Linux Kernel:2.4.7-10
gcc version 2.96 20000731 (Red Hat Linux 7.1 2.96-98)
It is compiled as:

g++ -g -I../quickfix/include -finline-functions -fexceptions
-D_XOPEN_SOURCE=500 -I. -c tradeclient.cpp

g++ -g -I../quickfix/include -finline-functions -fexceptions
-D_XOPEN_SOURCE=500 -I. -c Application.cpp

g++ -o tradeclient Application.o tradeclient.o -g -L../quickfix/lib
-lquickfix -lpthread -lxml2

I don't have a core file (none was produced) but I do have this from
GDB:

Justin,

Can you give some more details.  Are you running on Solaris or Linux,
which kernal?  What version of gcc are you using? Can you also recompile
with the -g option and post the core file so everyone can take a look at
the stack?
