Building Qt cross compile from windows

Question

[edit] Sorry, I out thought myself. I was using a .bat file to set environment variables that wasn't set up properly. When I went to a straight VS2005 command prompt, the configure ran fine. Sorry for the noise.[/edit]

I'm trying to compile qt-everywhere-opensource for embedded. I'm using MSVC2005. However, I guess I am confused on the process. I am getting compiler errors during the configure step. I thought the configure step was just trying to generate the needed makefiles, so I'm not sure what it is trying to compile.

I expected to modify the mkspec, but I'm not sure if during configure I should point to windows headers or sdk headers. I know during the build phase I should point to sdk headers, but I'm not getting that far.

I can change the errors by modifying INCPATH, there's also a QMAKE_INCDIR that seems to have an effect. It occurred to me that since I pulled the source, maybe configure needs to build the compiler tools, in which case I should point to MSVC headers. I also tried downloading the SDK and adding the path to it's bin folder to my path ahead of the -everywhere- source, but that didn't fix the problem and I don't want to jack up my system too much testing things.

Hope someone out there can help!

When you install Qt from source under Win32, you must:

1. Extend the PATH variable to include $(QTDIR)\\bin , where $(QTDIR) is the directory where you installed Qt.
2. Open a Visual Studio command prompt in $(QTDIR) ; a plain old Windows command prompt won't do (unless you run vcvars.bat to load Visual Studio's environment variables; but opening a Visual Studio command prompt directly is better).

At this point, configure should run properly, after which you can run nmake .

I suggest that you clear your previous installation attempts from your system before you try these steps.
