Can't build Qt5 (qtbase) on Windows XP (win32-msvc2005)

dfaure

In a cmd.exe prompt, using msysgit, I cloned git://gitorious.org/qt/qtbase.git.
Set QTDIR to that qtbase directory, added %QTDIR%\bin to PATH.
Made sure sh.exe is not in the PATH. Set
The problem:

configure -developer-build -opensource -nomake examples -nomake tests
fails with a link error for configure.exe, due to duplicated symbols:
@
Please wait while bootstrapping configure ...

and a lot more of the same.

Sample compilation line, to see the flags:

(funny that -opensource sets -DCOMMERCIAL_VERSION, but that's unrelated...)
Strange, too that my QMAKESPEC being set to win32-msvc2005 leads to win32-msvc2008 in the compilation line.

I had this problem too. It looks like there is no way around it except upgrading Visual Stduio. The problem is described here: http://stackoverflow.com/questions/2078087/local-classes-inside-inline-non-member-function-produces-lnk2005-with-msvc2005

The code that triggers the problem is in qlist.h:

@template <typename T>
Q_OUTOFLINE_TEMPLATE QList<T>::QList(const QList<T> &l)
: d(l.d)
{
if (!d->ref.ref()) {
p.detach(d->alloc);

    struct Cleanup
    {
        Cleanup(QListData::Data *d) : d_(d) {}
        ~Cleanup() { if (d_) free(d_); }

        QListData::Data *d_;
    } tryCatch(d);

    node_copy(reinterpret_cast<Node *>(p.begin()),
            reinterpret_cast<Node *>(p.end()),
            reinterpret_cast<Node *>(l.p.begin()));
    tryCatch.d_ = 0;
}

}

You can use the /FORCE linker option to get rid of the linker errors (the linker reports warnings instead). Here's a description on how to succeed with the complete build of Qt5 qtbase on XP using msvc2005 (so you don't have to upgrade): http://qt-project.org/forums/viewthread/27666/
