Set a project to build 64 bit dll?

[reactive]

How do I set my shared library project to build in 64 bit?
I'm not using any of the Qt libraries and I'm using the VS2008 compiler.
I looked in http://doc.qt.nokia.com/latest/qmake-project-files.html thinking it was probably
a .pro file setting but didn't find it. Thanks!

I usually build Qt in the MSVC command prompt. You can set the CPU architecture and word width in that command window using the normal MSVC bat-files for that.

Afterwards Qt Creator 2.2 will pick the correct compiler and word width for your library.

But my library isn't using Qt (I unchecked Qt core). In VS2008 you can change
the build configuration from Win32 to x64 per project.

I just realized I should have posted this in the tools section.
