[Qt-interest] Qt 4.5.3 and target architecture mismatch

[Malyushytsky, Alex]

VS has cross-compiler which builds 64 bit code on the 32 bit OS.
It does not mean you can run it, but you can build.
If you are running from the command line you have to setup environment for either 32 or 64 bit compiler.

>From command line it is defined in the project settings.
You mentioned before that if you specify target x86 VS complains that main.obj is 64 bit.
As for me this has nothing to do with QT, I would look at the settings if I were you.
At least try to rebuild project completely after you specify x86 target.

Hope this helps, sorry if not.

Regards,
     Alex

Hi Alex,

Thanks for taking the time to respond; it's greatly appreciated.

If you'll refer to my original post, I mention that the OS is 32-bit
(Server 2008 32-Bit), and in the project settings the platform is set to
Win32. I get errors if I set the target machine type to "x86" or "not
set". This is what's confusing me.

I've been through all the settings that I can find, and everything I can
see says I should be compiling for a 32-bit architecture. Hence my
wondering if there might be a Qt configuration issue.

Thanks!
