I have a bunch of libraries that I need to link against that I installed via macports. They are 64-bit libraries. I'm working on an application written with QT Creator and the .pro is set up. I downloaded the QT SDK for Mac OS X, but it is 32-bit and so the compiled code won't link against the 64-bit binaries that I got from macports. Ok. So I downloaded the QT SDK source and built from source using -arch x86_64. Now I have a 64-bit version of the SDK (I think) but it didn't build a QT Creator app.

So. I need to know one of 4 things:

Either, 1.) I'm guessing that a simple make command will convince the QT SDK to build the creator for me. If this is true, then what is the command (make creator?). barring that, I need to know

2.) The easiest way to get MacPorts to redownload the libraries that I installed with a 32-bit version (I keep seeing a "+universal" mentioned, but I haven't seen it on a line, and simply calling ports +universal install XYZ doesn't seem to work--perhaps I need to uninstall and reinstall the package?). Also, is this a stupid idea? or

3.) Someone who actually has a prebuilt 64-bit QT SDK installer so I don't have to mess with this. It is ridiculous that QT doesn't already have this available, in my opinion--SL has been out since, what, last August?

4--and this would take the cake.) I don't understand why I can't simply put a "compile-for-64-bit stupid" command directly into the QT pro file and have it build. There isn't really a reason why a compiler compiled in 32-bits couldn't compile to 64-bits is there?

Thanks.
