failed compiling in kdevelop3: missing file kdex.dtd
 

I'm using KDevelop 3.2.0 as IDE for C++, under Kurumin 5 and KDE 3.3.2.

When we make a new project, it creates a lot of files by default, including some files for KDE documentation.

There is a problem when compiling this docs: it gets an error <index.docbook:12: I/O error : failed to load external entity "dtd/kdex.dtd">.

Yet, I can compile the program typing 'make' in the directory "project/src".

What is the problem? Is it normal?

Besides, is there another c++ ide for kde?
