Problem with debugger
Pecan:
Ok, here we go again with the cut and paste.
Again paste the following routines over the last two routines in debuggergdb.cpp just like we did before.
Compile, quit CB, restart CB and do the test.
Notice I change two lines, commenting out
//cmd << 80000 + ::wxGetProcessId(); //make a unique sleep command
and added:
cmd << sleepPid;
because it appears SlackWare wxWidgets has a problem with addition in a "streamed" string.

Pecan:
Sorry, I found another problem. Let's do it again...
I had to change two more lines:
--- Code: ---//uniqueSleepTimeStr << wxT("sleep ") << 80000 + ::wxGetProcessId();
uniqueSleepTimeStr << wxT("sleep ") << wxString::Format(wxT("%d"),80000 + ::wxGetProcessId());
--- End code ---
If you'll change your build target to "Debugger", you can compile and link this code faster. But be sure to change it back to "All" when you're through

// start the xterm and put the shell to sleep with -e sleep 80000

kramed:
It works!!!!!
kramed:
I love you Pecan. Wonder how many posts this thread is up to. I am going to bed... Thanks again!
Pecan:
Thanks for your hard work and persistence. It'll make the code better for all of us.
