Can you explain why you can't install the libs on your target ?

shirisha

SGaist

Still that doesn't answer my question: since the target is running OpenSuse, why don't you use the package manager ?

shirisha

i d;t get u sir..am new one to qt .

SGaist

It's nothing Qt specific. So let's start again:

list item What exactly is your target ? Computer ? Embedded board ? etc.
What processor does it use ?
* What exact OS is it running ?

SGaist

To be able to help you, you should start by first answering my questions.

Not knowing what you are running on your board I can't answer.

hi all. i have the same problem.
What exactly is your target ? i wrote a simple Qt program for mini2440 friendly arm. Embedded boar linux gnu.
when i execute my program ( and comment running Qtopia) it show me this error : /armNEW: error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
i search and find this file in /usr/local/trolltech/qtEmbedded/.... so why i have error?
now what can i do now?

SGaist

Hi,
/usr/local/trolltech/qtEmbedded/ is a non standard path and probably not the same you have on your computer when cross-compiling your application.

You can use LD_LIBRARY_PATH to add that path for the loader to search before starting your application.

Hi @SGaist , I am building qt application for an arm embedded target.I have successfully transferred the project files via scp using qt creator. However, the application outputs this error:
error while loading shared libraries: libQtGui.so.4: cannot open shared object file: No such file or directory
How can I ensure I have the said library on my target?Is it something I need to cross-compile?
I have libQtGuiE.so.4 in /usr/lib
Thanks.
