Hi Akshat, top-posting intentionally, as we clarified most of it on IRC anyway.
You do not need to compile kdelibs if your distribution already provides it. If you still want to compile it, you must ensure you use the correct development environment. From the discussion it stemmed that you were using Kubuntu 14.04 LTS, which has a too old library set to get into current KDE development. If a beginning developer wants to do the coding examples mentioned in the tutorials on Techbase, compiling the basic libraries is not necessary, as those can be done on older distributions as well, except for the plasma5 and frameworks examples. So if you want to compile something from git master, make sure you read all the README and INSTALL files where the exact dependencies are usually described. Currently, if you want to get into KDE development, you should know that KDE4 is not actively developed anymore, but for occasional bug fixes and security fixes. Most of the projects have already migrated to the Plasma5 environment which needs Qt5 and the frameworks libraries that replace the previous kdelibs ones. Hope this helps :-) Regards, Myriam On Sun, May 24, 2015 at 1:13 AM, Akshat Tandon <akshat.tandon...@gmail.com> wrote: > While building kdelibs using kdesrc-build I am encountering > "undefined
