Qt Upgrade Repository..

[squidge]

Your using Linux, so therefore theres a high chance you have an option of upgrading Qt without uninstalling anything.

Secondly, if you can't find the latest Qt in a package format suitable for your distro you can always download the source and compile it.

Thank you.
But, would you please help to clarify "without uninstalling anything"
Do you mean I can download the source and build the source and copy every built .so files to overwrite those .so installed from Ubuntu repository?

Finally, I found the code at ftp://ftp.trolltech.com/qt/source/

Thank you very much.

No, I was thinking more along the lines of ./configure && make install, with the appropriate parameters passed to configure to state the installation directory.

Hi, my compilation configuration is

./configure -v -prefix /usr -debug-and-release -phonon -phonon-backend -declarative

./configure -v -prefix /usr -debug-and-release -phonon -phonon-backend -declarative

To copy to clipboard, switch view to plain text mode 

and the configuration output contains quite a lot of error messages

Among all the above error messages,
what is OpenVG? It's right here http://www.khronos.org/openvg/
but, do I need to install something?
or, how can I activate it?



Looking forward to your detailed explanation.
Thank you very much in advance.
