Creating cmake projects with KDevelop

[rracasanu]

Hello,

I'm sorry if this has been answered before or of this has an obvious answer but I'm new to KDevelop and cmake and could not find any reference to this problem.

I'm using KDevelop 3.5.6 of a Fedora 7 system and I'm trying to create and run the sample "Hello world program". So I started to create the project: Project -> New Project -> C++ -> CMake based projects -> Hello world program. After finishing the wizard, all the files have been generated, but the CMakeLists.txt file in the project's root folder contains only commented out lines and whenever I build the project I get this as output:

gmake[1]: Nothing to be done for `all'.

and the executable or object files are not generated.

Is there something I'm doing wrong or this is a problem related to the installation?

Thanks

Chances are the IDE already compiled the code for you. If there have been no updates since then, gmake will tell you there's nothing to be done. This is how (g)make works: It rebuilds a project only if the sources are older then the executables (output) files. Change the sources or `touch' them or delete the executable to see if this is true.

Thanks for answering.

Although I'm new to CMake, I have used make a lot of times before so I know how this works. The problem is that there is no object or executable being built.

To me it seems that KDevelop does not add the source files to the make files. For example, the demo project only contains one source file: main.cpp. The only file containing this text is the CMakeLists.txt file in the project's root folder, but this line is commented out like this:

#dataFile = main.cpp cmakesimple.png CMakeLists.txt

I have managed to figure this one out. In case anybody else has the same problem, they should try upgrading KDevelop to version 3.4.1 as this has solved the problem for me. Even if this version is not available for Fedora through the standard repositories, installing the package for Fedora Code 6 from the KDevelop site seems to work.
Now, the CMakeLists.txt file is correctly generated and the project builds properly.
