Hi all,
I'm running on kubuntu 10.04 and I've installed all the kde-sdk packages, as well as kdelibs, but while I can find most of the KDE headers in /usr/include/kde I cannot find kcomponentdata.h anywhere on my disk. What am I missing here?

Thanks.

On Debian and derivates (including Ubuntu) the kdelibs headers are in the kdelibs5-dev package, and getting the file list of that package will tell you where they are installed.
Why do you need to know where it is?

Thanks Pino, it solved the problem.
I was searching the file because I'm trying to write a little component (kio slave) and I needed the header to compile the project.
