cmake – re-ws.pl

While tinkering with spy camera, I found one detail that is significantly slowing the process of reverse engineering and debugging the applications, installed on its embedded Linux platform – finding final values of preprocessor directives and sometimes also results of sizeof() operator.

As I am not aware of any existing solution for that problem (I guess there might be some included in one of the more sophisticated IDEs, however I use Vim for development) it is good reason to create one. By the way I used cmake template I published some days ago to bootstrap the project. Continue reading “SADVE – tiny program for computing #define values” →

Writing unit tests along with the source code (or even before the code itself – see TDD) is currently very popular among programmers writing in languages like Java or C#. For C code, however it is a bit different. There are only a few frameworks enabling the possibility to write unit tests. One of them is quite special – it allows to mock functions. And its name is CMocka. Unfortunately there are not many resources that describes the process of setting up cmocka, especially together with cmake to allow programmers add new executables, tests and mocks without unnecessary overhead. But before showing how to do it, let’s go back to basics (if you already know them, you can skip next heading). Continue reading “Using CMocka for unit testing C code” →
