I didn't forget that, but you are right that I didn't really have Qt 4.7
in qtopiacore/qt.

The reason is that - in order to try to leave my v45 tree untouched - I
did:

$ mkdir qtv46
$ rsync -a qtmoko qtv46/
$ cd qtv46/qtmoko/

and now only work within the qtv46/qtmoko tree.

But unfortunately this is completely scuppered by the Git submodules,
because

- each submodule has a '.git' file (not directory) which points to a
  location under my original (v45) tree

- in each such location, the 'config' file has a 'worktree = ' line that
  points into the original (v45) tree.

Therefore Git commands in a submodule in the new tree actually update
the old tree, and leave the new tree unchanged.

Grrr...  well, it's been said before that git submodules are still in
their early days....

I believe I've now fixed the situation, by doing s:qtmoko:qtv46/qtmoko:
in all those '.git' and 'config' files, followed by

$ git submodule update -f
$ cd qtopiacore/qt
$ git checkout HEAD -- .
$ git clean -f -d
$ cd ../../build
$ rm -rf *
$ ../qtmoko/configure -system-qt -device gta04 && make

and that build is now running.

There's one more thing that is worrying me.  I haven't yet uninstalled
the v45 toolchain, which is in /opt/toolchains, and I think that the v46
build might be picking this up instead of the new xapt toolchain.
/opt/toolchains is mentioned in the build output here:

  Running configure (qtopiacore)...

and also in the TOOLCHAIN value in devices/gta04/environment.

Would it be a problem to pick up the v45 toolchain?  How can I check if
that is happening?

Many thanks,
