Developping for Qt 4.8.1 Embedded on Windows

  • Has anyone tried out to build a Windows Developing Environment for Qt 4.8.1 Embedded in order to build embedded Linux for ARM9?

    I have followed this

    I don't really know what to do at step 5. Any suggestions?

  • welcome to devnet

    where did you get lost in step 5?

    BTW: Did you consider also to use a linux installation for cross-compilation?

  • At step 5 i get this error:

    @C:\Users\damir.duric.MEC\Documents\qt-4.8\qt-4.8-src\tools\configure>qmake && mingw32-make

    I know Linux would be a lot easier but this is actually my problem -> I have to find a solution for windows 7.

    Any suggestions?

  • Concerning linux you could use virtual box with a linux installation and do the cross compilation there.
    This is what I am actually doing. Development on Win7 with msvc and major use on windows respectively wince. However, I have been using an OMAP board. the cross compilation with CodeSourcery compiler I have done on an Ubuntu installation in virtual box. This was relatively easy to do.

    It looks like the compiler is looking for the absolute path "/src/corelib/tools/qbytearray.cpp". This is not the typical notation for windows. The drive letter is missing.

    Did you check for the qbytearray.cpp where it is located?

  • you are right with the path, qmake did not find it because of the variable QT_SOURCE_TREE

    now i tried the version 4.8.1

    it produced a total different error:

  • You are still on step 5?

    I have no glue, but I guess that some of the defines might have changed to version 4.8.1. Personally I would try to get it to work with the 4.8.0 first. Otherwise you might have to fight on two fronts.
