Qtopia4 Core
« on: April 19, 2006, 02:03:03 pm »
I've build qt/e 4 aka qtopia-4-core, and am trying it out. It's pretty huge - had to install on sdcard and cross-link.

I've managed to get most of the demos to work, some don't build/link, either due to missing symbols or maybe because I'm using gcc2.95.3

The programs which build are:

books        composition  deform       interview    mainwindow   pathstroke   spreadsheet  sqlbrowser   textedit

Some won't run due to needing the SQL drivers. Loading speed is q slow, running speed OK-ish.

Still got a few things to fix though before programs will normally from qtopia1.5 desktop on Z!!!

yes, I build it just about everyday. I am surprised it actually compiles with gcc2

You can make it smaller by configuring -qconfig small or whatever.

the toolkit cross-compile goes wrong with building moc and rcc - it builds native arm versions, so I copied over the qt4-x11 versions I built for x86.

the real two cuplits are two demos which don't compile...  affine & gradients produce this error:

../shared/libdemo_shared.a(hoverpoints.o): In function `HoverPoints::eventFilter(QObject *, QEvent *)':
hoverpoints.o(.text+0x7c4): undefined reference to `HoverPoints::movePoint(int, QPointF const &, bool)'
hoverpoints.o(.text+0x870): undefined reference to `HoverPoints::movePoint(int, QPointF const &, bool)'
collect2: ld returned 1 exit status


arthurplugin (this is probably because, as I'm cross-compiling, QtDesigner was built for arm):
make[1]: *** [../../plugins/designer/libarthurplugin.so] Error 1

My fees for being your beta tester will be very reasonable

I figured so, but I wanted to go max-out and see what happened! Am I allowed to put up an IPK of the arm binaries and .so files built for Z?

Is there going to be a ROM for Zaurus using Qtopia 2.2 on qt-core 4?

oh yeah, here's the command I ran after I unpacked the tar.gz:

./configure -embedded arm -xplatform qws/linux-arm-g++ -big-endian --prefix=/home/zaurus/QT4

this is on suse10.0 machine

PATH:
/usr/local/Trolltech/Qt-4.1.2/bin:/home/zaurus/Embedix/tools/bin:/home/zaurus/bin:/usr/local/bin:/usr/bin:/usr/X11R6/bin:/bin:/usr/games:/opt/gnome/bin:/opt/kde3/bin:/usr/lib/mit/bin:/usr/lib/mit/sbin

(where the first part of the path was an already built qt-4-x11 install so I could use the binaries; there's a softlink from /home/zaurus/Embedix in /opt)

one other thing. the trolltech build scripts are a bit broken in that it creates arm binaries for tools it needs to run on the host...

so you end up with arm binaries for qmake, moc, rcc & uic. rename them (e.g. to qmake.arm) and copy over the x86 binaries (which I got from my qtopia-x11-v4 build).

you need to try different compile options then!!!

using -qconfig minimal breaks things:

when you've got this far it means you've got a working QTC4 package, just go into each demo directory in turn and make; you can build most of them except affine and gradients.

Maybe Mr lpotter will issue a patch or something.

affine and gradients fail because of missing HoverPoints::movePoint
arthurplugin fails because of the missing QtDesigner library

Another minor snag: if you don't use --prefix, qtopia core installs into /usr/local/Trolltech/QtopiaCore-4.1.2 but the Makefiles for the examples expect /usr/local/Trolltech/QtopiaCore-4.1.1 (I built from qtopia-core-opensource-src-4.1.1.tar.gz on x86 linux).

Qtopia 2 does not compile nor work with Qtopia Core 4. They are incompatible, and that measn we can fix up Qtopia's API.

I would suggest trying the snapshots.

No testing is being done using gcc2 for Qt 4, that I am aware of.

I tried compiling Qt4/E for my C1000 some time ago with some success. I actually cross compiled it on my PC and was able to run some examples (textedit at least). I am running pdaXrom and used their SDK. The problem I ran into was getting the pointer and keyboard to work. Pointer (touchscreen) didn't work at all, and the keyboard was mapped all wrong. Maybe this was due to cross compiling. I tried several options for input devices but nothing worked. I'm somewhat interested in this, especially if qt4/e is significantly faster than qt4/x11...

Any thoughts about input devices?
