Fix compilation on kdevplatform 1.6


KTechLab is an IDE for microcontrollers and electronics. It supports circuit simulation, program development for microcontrollers and simulating the programmed microcontroller together with its application circuit.



Getting the source

KTechLab's source code is located in GIT repositories.

The official repository is located on github:

Other notable GIT repositories are located on sourceforge:

  • main KTechLab repository:

    • git://
    • contains the contents of the previously used SVN repository
  • developers' own repositories:

    • git://
    • git://
    • git://
      • the master branch should have the same content as the official master branch from github
    • these repositories contain work-in-progress code, which is supposed to be merged in the master branch on github

Checking out from GIT can be performed with the following commands:

git clone git://
cd ktechlab
git checkout -b master --track origin/master

Building and Running

Required dependencies

  • Qt4 -dev
  • cmake
  • glib -dev

Optional dependencies

  • KDE4 libraries -dev
  • KDevPlatform libraries -dev
    • NOTE: without the following two components, only the unit tests will be built; those are not useful for end-users
  • GPSim -dev, for microcontroller support
  • Eigen2 -dev, for unit tests; generally it is not needed for builds targeted to end-users, but it is useful for development

Since KDE4, all Makefiles in KDE projects are generated using CMake. After checking out the source (see Getting the source), here is how to compile and install KTechLab. CMkake is not a run-time dependency of KTechLab.

  1. By using a terminal, navigate to the top-level source-directory

  2. Run the shell script This command compiles KTechLab into the directory simple-build, installs it into the directory simple-install and sets up the user-specific settings (syscoca, mime database) for the current user.

  3. Launch KTechLab by running the script


KTechLab should start running at this point. If this simple method of launching KTechLab does not work, please contact the developers, because you have found a bug.

Running by multiple users with same build/install directory

It is possible to run an already compiled and installed version of KTechLab by multiple users. In order to do this, run the script from the simple-install/bin/ directory

     sh simple/install/bin/

Then you can launch KTechLab as usual


Running a build when the source/build/install directory has been moved

It the source directory has been moved, then the setup procedure has to be rerun. This is due to the fact that in the launch scripts of KTechLab, absolute directory paths are generated. The compilation step should be a lot faster than previously, because the source files have not been changed, so the existing build is just verified, not recreated.
