You should get familiar (if not present) with
- cmake (mostly by working on concret tasks)
- c++ programming, (this could for example be done by inspecting present
code)
- Integrated development environments (QtCreator or KDevelop)
- build tool chains gcc, make, binutils
- UML Modelling tools for example https://umbrello.kde.org/, with which
you can import c++ code and inspect and/or design new classes
Concrete tasks to learn from:
1. try to integrate generating sqlite database from
https://cgit.kde.org/kmymoney.git/tree/kmymoney/plugins/ibanbicdata/germany?h=4.8
2. replace the code, which uses the bank data text file with code that
uses the new sqlite database
3. write/refactor unit tests for the new code
4. It may required to refactor/simplify the cmake build system while
working on it
5. add additional countries to the generated sqlite database (see
https://cgit.kde.org/kmymoney.git/tree/kmymoney/plugins/ibanbicdata?h=4.8)
6. extend ktoblzcheck code to use the additional countries
7. write/refactor unit tests for the new code
8. update ktoblzcheck documentation
Some generic rules:
1. Use a git repo for development to track changes (private clone of
ktoblzcheck on sf.net)
2. Make single commits for each task or step, no commits with tons of
collected change. You can reorganize (rebase) or squash commits later
1. On extending classes, make sure, that code will work cross platform
e.g. do not use hardcoded pathes.

Ralf
