The sourcecode


This software needs to be compiled before you can use it. In order to be able to do this, open your package manager
and install the Qt4 development package. That's all, your package manager will take care of all the dependencies
and will install the GCC/G++ compiler.
On Linux Mint / Ubuntu, open a console and enter: sudo apt-get install libqt4-dev libqt4-core g++
On openSuse: zypper in libqt4-devel

Now, extract the file that contains the source.
Open a terminal (console) and cd to the directory that contains the source files.
Enter: qmake
Enter: make -j16
Enter: sudo make install
Now you can run the program by typing sct <enter>

In case you can not open your serial port, remember that you need to be a member of the group "dialout".
On Linux Mint / Ubuntu, open a console and enter: sudo usermod -a -G dialout <username>
On openSuse, start Yast and go to Security and Users -> User and Group Management -> Users -> click on the user -> Details -> check "dialout" in the "Additional Groups" list.
