Could someone help a newbie with QT?

[Ameeca]

Hi all,

http://www.qtcentre.org/threads/45065-configure-embedded-QT4.7.4

http://stackoverflow.com/questions/7662404/installing-qt4-7-4-for-embedded-linux-multiple-errors

I was wondering if someone could help with my config of QT4.7.4 for iMx233?

I'm an absolute beginner with Linux and developing for embedded Linux. I'm trying to install QT for embedded Linux onto my Fedora 15 laptop to target an i.Mx233.

Firstly, within the qt-everywhere-opensource-src-4.7.4 folder, I enter the command:

Qt Code:

1. PKG_CONFIG_PATH=/opt/freescale/pkgs ./configure --prefix=/opt/freescale/pkgs -v -embedded arm -xplatform qws/linux-arm-imx -phonon -force-pkg-config

PKG_CONFIG_PATH=/opt/freescale/pkgs ./configure --prefix=/opt/freescale/pkgs -v -embedded arm -xplatform qws/linux-arm-imx -phonon -force-pkg-config

To copy to clipboard, switch view to plain text mode

I'm not sure if this is even correct - I have no idea what the PKG_CONFIG is or where to find it.

With the linux-arm-imx qmake conf file:

The install was obviously unsuccessful but I'm not sure why the .cpp files are failing.

As I said, I'm a beginner with Linux and I realise helping a newbie can be very tedious but I'm lost with this and any help would be greatly appreciated.

Thanks.

That's a very unusual message, and I haven't tried this on 64-bit host.

When doing some work on 64-bit host, I had to install following 32-bit support packages. Might be needed for this case as well:

ia32-libs libc6-dev-i386 libc6-i386 lib32gcc1 lib32stdc++6 g++-multilib lib32z1-dev lib32ncurses5-dev

[JamesRobinson]

I am also trying to build Qt-Embedded inside ltib. I have applied Vladan's patches for QT4.7.4 (Thank you) but I get the following error.

error: failed dependencies:
libc.so.6()(64bit) is needed by qt-everywhere-opensource-src-4.7.4-0
libgcc_s.so.1()(64bit) is needed by qt-everywhere-opensource-src-4.7.4-0
libm.so.6()(64bit) is needed by qt-everywhere-opensource-src-4.7.4-0
libstdc++.so.6()(64bit) is needed by qt-everywhere-opensource-src-4.7.4-0
linux-vdso.so.1()(64bit) is needed by qt-everywhere-opensource-src-4.7.4-0

any pointers? I think the build set is picking up my host libraries...

I am running 10.4.03-LTS 64 bit. I have run the Linux host script. and have the mk_mx_sd_mmc tool for the sdcard also.

I can only get the ltib to compile the (min) configuration under selectype. Can any one verify that the ltib builds any of the other configs (gnome,develop tools....)

Thanks.

[Ameeca]

Thank you very much Vladan. You are the only person to reply to my issue across 5 different forums, unfortunately I've read through the links and it didnt help my problem.

Thank you again though.
