Question

Does anybody know how i can debug Navit . It doesn't matter if i can do it in MS Visual Studio or Eclipse. It doesn't matter if I have to do that under Windows or Ubuntu.

Answer 1

Navit is a C application, and can be debugged using any debugger that can debug C programs.

The details depend on your development environment (IDE/editor, compiler, operating system).

For development on Linux, popular debugger options include:

• gdb (text-based)
• DDD (graphical)
• Eclipse CDT (graphical)
• Pyclewn (vim plugin)

Some notes:

• Usually you want to build in debug mode (cmake option -DCMAKE_BUILD_TYPE=Debug ). This will build with symbols and disable optimizations, which makes debugging easier.
• When running the navit binary without installing it, you must run it from the directory it is created in - otherwise it will not find the plugins (which are compiled to separate libraries). Take care to configure the current directory correctly in the debugger.
