Re: [Gumstix-users] How to build/develop GUI in Angstrom Linux

[joe j. <joe...@qi...>]

I found an interesting guide for Creating and Using a Qt Embedded SDK.  

http://docs.openembedded.org/usermanual/html/ch05s08.html

I was able to build the SDK on my development Linux workstation and build
the provided example, but I was unsuccessful running it on target.  I get
the following error. 

# ./qte-example: error while loading shared libraries: libQtGuiE.so.4:
cannot open shared object file: No such file or directory. 

Does anyone have an idea what is going on here? Do I have to rebuild my
kernel/RFS for QT apps to run?  Again, my goal is to use QT to develop GUI
application for the gumstix.
