short disclaimer: i am not a SW-developer, so please bear with me. I also replace some full paths with $DEVICEROOT for the sake of this post, so i hope i did not introduce any errors there.

i made this changes to the build/scripts/qt.sh

patch -p3 < ../$PATCHESDIR/qt-everywhere-opensource-src-4.8.0_kobo.patch

i also added this, but i cannot remember why

export PKG_CONFIG_PATH=$DEVICEROOT/lib/pkgconfig

in the ./configure line i removed the -qt-gif like JonnyXDA mentions, but i added this:

-I${DEVICEROOT}/include -D QT_NO_QWS_CURSOR -D QT_NO_QWS_QPF2

this is the full line btw:

Spoiler:

./configure $CPPFLAGS $LIBS -release -no-accessibility -system-libmng -no-nis -no-cups -no-xshape -no-xrandr -no-xkb -no-xinerama -no-xcursor -no-sm -system-libpng -system-libjpeg -qt-zlib -embedded arm -xplatform qws/linux-arm-g++ -no-qt3support -exceptions -opensource -no-pch -qt-freetype -qt-gfx-qvfb -confirm-license -dbus -ldbus-1 -nomake examples -nomake docs -nomake translations -nomake examples -nomake docs -nomake demos -scripttools -xmlpatterns -no-opengl -depths all -qt-gfx-transformed -qt-gfx-linuxfb -no-mouse-pc -no-mouse-linuxtp -no-mouse-linuxinput -no-mouse-tslib -no-mouse-qvfb -no-mouse-qnx -no-armfpa -no-neon -openssl -lrt -I${DEVICEROOT}/include/dbus-1.0 -I${DEVICEROOT}/lib/dbus-1.0/include -I${DEVICEROOT}/include $QT_EXTRA_ARGS -D QT_NO_QWS_CURSOR -D QT_NO_QWS_QPF2

then it gets messy. i ran make, got some errors and starting fixing things manually:

in qt-everywhere-opensource-src-4.8.0/src/gui/text/text.pri i added
LIBS_PRIVATE += -ldl
and in qt-everywhere-opensource-src-4.8.0/src/3rdparty/webkit/Source/WebKit/qt/tests/tests.pri
LIBS_PRIVATE += -lpng12 -lz -Wl,-rpath,$DEVICEROOT/lib -L$DEVICEROOT/lib -licuuc

it's probably not needed but at the top of my build-all.sh i have this:
CPPFLAGS+=" -march=armv7-a -mcpu=cortex-a8 -mfpu=vfpv3 -mfloat-abi=hard -mthumb -mthumb-interwork -mtune=cortex-a8 \
-Wa,-march=armv7-a,-mcpu=cortex-a8,-mfpu=vfpv3,-mfloat-abi=hard,-mthumb,-mthumb-interwork \
-I$DEVICEROOT/include -I$DEVICEROOT/usr/include"

i think i added that to get around some compilation problems with the other packages but as a consequence my qt also got compiled with these settings.

hope it helps.

I was able to compile Qt 4.8 from Kobo's github with the new toolchain. I documented my exact steps on a fresh install of Ubuntu 12.04 32 bit. Here's what worked. First install some stuff we need to compile.

sudo apt-get install git gettext autoconf libglib2.0-dev libtool build-essential libdbus-1-dev

Then make some directories and download the code.

mkdir -p ~/kobo/fs ~/kobo/tmp
cd kobo
git clone git://github.com/kobolabs/Kobo-Reader.git

After that's finished, extract the new toolchain and create symbolic links in /usr/local/bin.

cd ~/kobo/Kobo-Reader/toolchain/
tar jxf gcc-linaro-arm-linux-gnueabihf-4.8-2013.04-20130417_linux.tar.bz2
cd gcc-linaro-arm-linux-gnueabihf-4.8-2013.04-20130417_linux/bin
for f in *; do sudo ln -s `pwd`/$f /usr/local/bin/arm-linux-${f:20}; done

Create a file named 'build-config-user.sh' in ~/kobo/Kobo-Reader/build/ and add these lines.

DEVICEROOT=$HOME/kobo/Kobo-Reader
QT_EXTRA_ARGS="--prefix=$HOME/kobo/qt -no-webkit -D QT_NO_QWS_CURSOR -D QT_NO_QWS_QPF2"

In ~/kobo/Kobo-Reader/build/scripts/glib.sh, replace CFLAGS="${CFLAGS}" with CFLAGS="${CFLAGS} -marm"

There's a few changes that need to be made in ~/kobo/Kobo-Reader/build/scripts/qt.sh. First change the Qt version from 4.6.2 to 4.8.0, then remove the following options in the ./configure line:

-qt-gif
-qt-gfx-qvfb
-qt-gfx-transformed
-qt-gfx-linuxfb
-no-mouse-pc
-no-mouse-linuxtp
-no-mouse-linuxinput
-no-mouse-tslib
-no-mouse-qvfb
-no-mouse-qnx

I couldn't get busybox to compile, so I just removed it from ~/kobo/Kobo-Reader/build/build-all.sh.

Now all that's left is to start compiling.

cd ~/kobo/tmp
KOBOLABS=$HOME/kobo/Kobo-Reader
~/kobo/Kobo-Reader/build/build-all.sh

Hopefully we'll be able to get the tweaks plugin working with the latest firmware versions soon.

Thank you for this information.

It sounds like that the developer of kobo don't want to leave usable sources.
Of course there is the great danger that someone could make the device to something that is much better!

I miss Tweaks so much I'm trying as well to resurrect it for 2.8.1. So far I'va had no luck with compiling qt, thanks Kevin for the detailed guide! I'll try those directions as soon as I can.

[friedmandu]

Yes, yes! Bring back the tweaks!

Hi all, I'm new on this forum and I read carefully all posts; very, very interesting.
In particular post #91 by goenieg has been acctracting me, so I decided to try.
- Downgraded my Glo to 2.5.2
- Followed exactly the instructions
No error messages after each one of the 3 updates.
pushing library and home nothing happens....
Sniffing around in Glo via Telnet, "ls -R kobotweaks.ini" found nothing. OK, I create a new one in .kobo with the [Global] + "compatFirmware=2.5.2", restarted.... once more nothing.
Looking inside the 3 .tgz (and .zip too) I noticed that koboroot_tweaks file was unreadable, other two are OK.
Now I'm here asking if someone of you can point me to a location where I can download a valid KoboRoot_Tweaks.zip (or .tgz).
Furthermore, any problem if I apply KoboRoot_Tweaks now, without repeating all procedure from scratch?
Please help me...

I had some problems with the Tweaks on my Mini and firmware 2.5.2, solved with this fix by KevinShort, maybe you want to try.
Before doing that, though, I seem to remember that in order for the "Tools" menu to show you first had to open a book or go to the library. Then back to the home menu you would see the "Tools" on the bottom of the screen.

I missed it too, also to use as a launcher is really better than PNG based launcher, because of tiles tend to move around the Home

[KevinShort]

I made the changes mentioned by stefjan in this post and then compiled the tweaks plugin using my newly compiled qmake. It should work on the Touch and Mini since they don't have the new home screen. Just extract the zip file and copy the KoboRoot.tgz file to the .kobo folder on your Kobo.

Thanks, Kevin, works fine (Kobo Mini, 2.81).
Only issue, I can't get Shelves to start under CustomCommands (Shelves=tweaks.shelves()), did I do something wrong or is this one broken?
Koreader and other apps work fine here!

[giorgio130]

I remember an option in the original Plugins to dump the layout of the current window. That would be very useful to adapt Tweaks to the new home layout, but I really can't find out how that was activated. Also, a fast way to find the changes is the interactive qtScript shell, ah- said:

Great news: QtScript is there and fully usable, so this might be a great way to develop plugins. I wrote a plugin that exposes QtScript over the network, so you can just telnet to your Kobo and mess with stuff. This allows access to pretty much everything exposed by Qt introspection.

Source (and some documentation) is at https://github.com/ah-/koboplugins, and attached is a binary version if you don't have the full development environment set up yet. Copy it to /usr/local/Kobo, reboot and open the library once to load the plugin. If you have any issues with it, just delete libqtscript.so and you should be back to normal.

Example use: Telnet to your Kobo (port 1337) and execute "aw.findChildren("label")[0].text = "QtScript""
This changes the text of the "START" menu to "QtScript". Without compiling anything and interactive.

I've installed KevinShort's version on my Glo but it doesn't seem to be included, I just get

giorgio@giorgio-laptop:~/kobo/tmp$ telnet 192.168.0.101 1337
Trying 192.168.0.101...
telnet: Unable to connect to remote host: Connection refused

fantastic: would you expect it to work under 2.6.1?

It should work fine with 2.6.1.

It's possible that the shelves option no longer works with the new firmware. I'll be sure to post if I come across any possible solutions.

Hmm, I don't know about an option to dump the layout from the plugin itself, but QtScript was one of the first things I tried. I've attached libqtscript.so below, copy it to /usr/local/Trolltech/QtEmbedded-4.6.2-arm/plugins/imageformats/. However, it doesn't quite work. It does open up port 1337, but I never get a prompt and my Glo reboots just a few seconds after connecting.

The new homepage on the Glo is called "DragonHomePageView". I added this to include/HomePageGridView.h and also edited TweaksPlugin.cpp to try to patch the reading life menu, but when it tries to set the text to "Tools" my Glo reboots. If I comment out the line that sets the text my Glo doesn't reboot, but the plugin doesn't have any effect on the reading life menu. Also, after adding DragonHomePageView to the plugin, qtscript no longer causes my Glo to reboot and I'm able to type stuff in, but I get no output whatsoever.

Already tried both fixes, no hope. I keep on suspecting that koboroot_tweks.zip I can't open, the others 2 zips I can... Could you kindly attach it here (or PM francescangeli dot f at gmail dot com) ?
Thank you for answering...

Sent. You were renaming the file from KoboRoot_tweaks.zip to KoboRoot_tweaks.tgz ?
