Re: [Qt-creator] Qt Creator portable for Windows

[Coda Highland]

Holy crap, I forgot all about subst. It's been forever since I've used it.

Yeah, that'll work. That'll work beautifully. Just create a subst'ed
virtual drive, install Qt on it, and then modify qtvars.bat to make
sure the subst is in place.

Re: [Qt-creator] Qt Creator portable for Windows

[M. Bashir Al-Noimi]

Hello,

As Coda said, it's easy to make Qt Creator portable but what about Qt?
Qt installer in windows needs absolute paths (at the end of installing 
process you'll find that the installer execute patches for absolute 
paths) so making Qt it self portable is exhausted procedure but I fixed 
this issue easy when I used TrueCrypt  
because it's creating virtual hard drive on your portable media thus you 
can install Qt and Qt Creator on you portable media then you can load it 
anywhere you go.


If you don't want to use TrueCrypt try this instead:
Create patch file (*.bat) and include "*subst*" command for creating 
virtual drive from specific folder (you can point to relative path of 
folder by using %CD% constant).

Qt looks for plugins in a path predetermined at build time. I think
you can override this behavior with a qt.conf file in the same
directory as the .exe file, but I don't know the syntax of this file
and you'd have to put that file alongside every .exe generated by

I don't know if it supports it or not. My guess is it doesn't. But 
that's the version that comes with Xcode 3.1.4 which is the highest 
version compatible with OS X 10.5.

I guess I am out of luck. :)

It says "Apple version gdb-967."

Does this support mixed disassembler/source code at all?

I.e. can you get such output from this version of gdb 
when run "manually" from a terminal?

Break View, context menu, "Set Breakpoint at "throw"".

If it's not there, set a breakpoint on the function "__cxa_throw".

Right now I have the impression that gdb's reverse execution is too slow 
and not robust enough for daily work, even in 7.1. So it's nice to have
the option, but it should be used very consciously ;-)

[Qt-creator] Exception debugging

[Laurent Desmecht]

Hi everybody

I am debugging some code in qtcreator, this issue is that the debugger don't
stop when an exception is thrown. Because of this it's quite difficult to debug 
one crash.
In gdb, it is possible to add a break point with the command "catch throw" but
I have not found any way to do this in qtcreator.

You were right! After switching this option off, I am able to continue 
debugging.

However some time ago, when I was testing this feature (may be a month ago), 
debugger worked fine..

Works here, also with gdb 7.0.1.

The log indicates you've switched on 'Enable reverse debugging'.
Does it make a difference if you switch that off?

Hm, I don't think I quite understand your scenario. What kind of
