QT4.6 and scratchbox incompatability

Hi,

Hi,

I installed QT4.6 for linux/x11 (qt-sdk-linux-x86-opensource-2009.05.bin) on Ubuntu 9.1. I designed the UI in QTCreator 1.3, compiled my application with no errors and it ran successfully in the native WMWare environment within QT.

Flushed with success I fired up the scratchbox (x86 target) which has libqt4-maemo5-dev installed (and qt4.5.2).

The x86 compilation failed.

qmake -project
qmake CamerDepthOfField
make

produced the following:

Am I being too ambitious or have I managed to misconfigure the libraries/got the wrong versions? What do I need to check or update?

Many thanks,
David

You cannot compile Qt 4.6 specific code against Qt 4.5.3. There is wiki explaining how to install Qt 4.6 technical preview in Fremantle scratchbox: [url]http://wiki.maemo.org/Qt4Hildon#Fremantle[/url]

[QUOTE=davidmct;693335]Hi,

The x86 compilation failed.

qmake -project
qmake CamerDepthOfField
make
[/QUOTE]

Try running /opt/qt4-maemo5/bin/qmake -project; /opt/qt4-maemo5/bin/qmake CamerDepthOfField;make

You're propably using the qmake that is included in the 4.5.x version.

If it's installed.

Hi,

I had previously installed the Qt4.6 technical preview and the commands...

"/opt/qt4-maemo5/bin/qmake -project
/opt/qt4-maemo5/bin/qmake CameraDepthOfField.pro
make
"

Worked a treat. Note that without the .pro extension qmake failed to find the file.

Any suggestions on how I can change the version being used by default? The $PATH env variable is currently ...
PATH=/host_usr/bin:/scratchbox/devkits/git/bin:/scratchbox/devkits/svn/bin:/scratchbox/devkits/doctools/bin:/scratchbox/devkits/debian-etch/bin:/scratchbox/devkits/perl/bin:/scratchbox/tools/bin:/targets/links/arch_tools/bin:/scratchbox/compilers/bin:/bin:/usr/bin:/usr/local/bin:/usr/X11R6/bin:/sbin:/usr/sbin

Many thanks again for the assistance.

The easiest way is to remove Qt 4.5.3 and Qt 4.6 and install Qt 4.6 back.

Hi,

Sorry to be a bit naive but what is the best way to uninstall?

I installed Qt4.6 outside scratchbox and the technical preview within scratchbox.

Thanks,
David

further note.

I installed libqt4-maemo5-dev as per the instructions you pointed at. I do recall that the step ... ./autogen.sh QT_PATH=/opt/qt4-maemo5/bin in the following failed because ./autogen.sh cpuldn't be found.

[sbox-FREMANTLE_X86: ~] > cd ~/your/project/folder
[sbox-FREMANTLE_X86: ~] > make distclean #dont worry if it fails
[sbox-FREMANTLE_X86: ~] > ./autogen.sh QT_PATH=/opt/qt4-maemo5/bin
[sbox-FREMANTLE_X86: ~] > make

I assume this could be as simple as the QT_PATH not being set.

It says [I]If you happen to use autotools[/I] and you are not using autotools, but qmake instead.
