The current debugger should be able to display all variable values (except those defined with absolute and maybe those in procedures defined within procedures) So please let me know in what situation it fails (if gdb is able to show them) Properties are a different beast.

It uses gdb as > debugger backend. doesn't it? Yes. But not every variable has a simple mapping in the debugging info. MSEGui does some more tricks to fill some gaps. The codetools can probably provide enough information to map. Marc can probably give more details.

The IDE shows the values. Set a breakpoint and then move the mouse over the variable names in the code.

Re: [Lazarus] Terminal window, workaround
Hello: I've decide to use the this work around. I write to filetext and in a terminal I use "tail -f ". It lets me stop in a breakpoint from the IDE and watch in the terminal the current value with a writeln. It's not the best, but it works for what I need. May be later I will learn how to use the gdb from command line. By the way, I thought gdb was unable to display Pascal variables, but if gdb is able to display the value of any variable in Pascal, what's the problem of Lazarus's IDE in displaying the value? It uses gdb as debugger backend. doesn't it? Regards Santiago Amposta around svaa wrote: Hello: I have 0.9.26 on Ubuntu 7.10.

Re: [Lazarus] Terminal window
What happens if you open the application by typing its name in a console window? The console window remains there during execution of the program, and receives some output, though this may not be the output you require.

But this may have been in the GTK version using X11. When I try it now, it gives an error Debugger: Exception while creating process: Executable not found: "xterm" But I have a wrong path somewhere ... Maybe someone else can try as well.

You have two options: a) View / Debug windows / Debug output This shows the output of your program, but it is not as mighty as a your favorite linux terminal. b) start your favorite terminal and use the gnu debugger directly.
