Hi, while practicing I've reached the second KDE tutorial but I keep getting a CMake error when trying to configure. The tutorial can be found here.

The error I receive is the following:

Code: Select all

-- Configuring incomplete, errors occurred!


I played around with the CMakeLists.txt without success and googled about the error, also without success. There are two things that seem weird to me: first, I found almost no reference to such an error in Google, and also, the first tutorial configures, compiles and runs smoothly. Any pointers at what might the problem be?

Which version of CMake do you have installed?
Also, which version of KDE Libs do you have installed?

hi there, thanks for your reply. Here's the information requested:

KDE Libs version is 4.2.2 and in regards to CMake:

Code: Select all

sh-3.1$ cmake --version
cmake version 2.6-patch 2


Can you please check that the CMakeLists.txt file for both projects matches that on the website, and no special characters ( non ASCII ) have been introduced.

Thanks a lot! Apparently the problem must have been with the non ASCII characters, since after rewriting the file from scratch it worked, but now I'm getting a set of error messages on the make stage. I'm researching now, but they are very cryptic for me at the moment:

Any extra help with this would be very appreciated.

It worked! Thanks a lot bcooksley for the assistance!

Now I was thinking, because after all, in order to fix it I had to rewrite the whole code, since I wasn't completely sure of how to see and remove those characters. In this case I just rewrote it on 10 minutes, but what if some day I'm working with a big project, I wouldn't just start all over right? :-P

So, besides of the fact that I'm already researching about Emacs (yeah, that's the one I use) in order to be able to fix this kind of things in the future, or at least be able to fix them in a more efficient way, how did those characters get there if I wasn't even able to see them? Is there a way to prevent that kinds of things from happening?

Thanks again!

Unfortunately there are usually no automated means of preventing things like this from happening. I have not encountered it myself, although I use Vi/Kate.
