[george@george trunk]$ gambas3
Segmentation fault (core dumped)

Thank you!  I can't seem to get the IDE running in gdb.  If I go to my
project directory gdb just runs my project and everything runs fine.  If I
cd to my src it tells me no project file!

Here is some output:

[george@george bin]$ cd /home/george/trunk/main/gbx/
[george@george gbx]$ gdb gbx3

Not sure where else to run gdb from?

You must recompile the project before, because it has been cleaned by "make 
install".

[george@george gambas3]$ gbc3 -agt
OK
[george@george gambas3]$ gdb gbx3
...

It seems to be a bug in Qt. Do you have some specific printer configuration?

Re: [Gambas-user] Segmentation fault (core dumped)

[Dr.Diesel <dr....@gm...>]

Don't think so,  but i do have one default printer setup, it works fine
though?

I deleted my default printer and gambas now works fine!  This is very weird? 
I am guessing I need to report this to my distro, what do you think?

As always, many thanks!

Re: [Gambas-user] Segmentation fault (core dumped)

[<tob...@t-...>]

   Dear Mailing-List,
   my question today is: Is there any possibility to use a compiled Gambas
   program on a linux pc without Gambas?
   I think there's no way because a compiled gambas program - as I understood -
   is just byte code which is interpreted by gbr2 (in my case). I think just
   copying this file would be the most stupid way to handle this but I wanted
   to ask to be sure. :)
   Regards,
   Tobi
