BB PB - ldd:FATAL: Could not load library libQtGui.so.4

[martonmiklos]

Hello all,

My setup is:
KUbuntu 12.10 x86_64

QtCreator 2.6.3 binary

Qt 4.8.3 cross-compiled from git using this guide:
http://qt-project.org/wiki/Building-Qt4-for-BlackBerry**

It had been installed to the /usr/local/Trolltech/QtLighthouse-4.8.3-arm folder

I was able to create the debug token, and it shows up fine on my Playbook.

I have created a blank BB widget based application, and tried to run it on the device, but it fails with the following:

[code]

ldd:FATAL: Could not load library libQtGui.so.4
[/code]

The bar-descriptor.xml is the stock QtCreator created and contains the following lines:
[code]
<env value="app/native/plugins:/usr/lib/qt4/plugins" var="QT_PLUGIN_PATH"/>
<env value="app/native/lib:/usr/lib/qt4/lib/" var="LD_LIBRARY_PATH"/>
[/code]

Something is shows up when I try tor un it on the device, but it is just a flash.

I have managed tio get it working in the following way:

Turn off the shadow building or move your bar-descriptor.xml by hand to the shadow build folder.

I needed to add the following to my project file
[code]
package.target = $${TARGET}.bar
package.depends = $$TARGET
package.commands = blackberry-nativepackager
-devMode -debugToken /home/mm/Dokumentumok/blackberry/debug_token.bar
-package $${TARGET}.bar -arg -platform -arg blackberry
bar-descriptor.xml $$TARGET
-e $$[QT_INSTALL_LIBS]/libQtCore.so.4 lib/libQtCore.so.4
-e $$[QT_INSTALL_LIBS]/libQtGui.so.4 lib/libQtGui.so.4
-e $$[QT_INSTALL_LIBS]/libQtOpenGL.so.4 lib/libQtOpenGL.so.4
-e $$[QT_INSTALL_LIBS]/libQtNetwork.so.4 lib/libQtNetwork.so.4
-e $$[QT_INSTALL_PLUGINS]/platforms/libblackberry.so plugins/platforms/libblackberry.so
[/code]

And I needed to modify the Project's Run settings (sidebar -> Projects, and select the Run under the project):

Remove the "Create packages" step
Add a new deploy step with the Add Deploy step:

• Choose custom process step.
• Command: make
• Arguments: [your target app name].bar
  (move it above the Deploy packages step)

Hit run...
Wait...
And be happy :)

Unfortunatelly this method packs the used Qt libraries to the bar file, which causing some overhead, but I have not been able to figure ut better method.
