Building

With toolchain installed you are ready to compile Mimiker. Before you run make in project's root directory, please have a look at config.mk file. There are several important configurable options there, including:

• KASAN=1: enables Kernel Address Sanitizer (dynamic memory error detector), which finds buffer overruns and other nasty memory related bugs,
• KCSAN=1: enables Kernel Concurrency Sanitizer (data races detector), which identifies variables that are accessed from multiple threads without proper synchronization,
• LOCKDEP=1: enables Kernel Lock Dependency checker, which identifies violations of locking order that may lead to deadlocks in the kernel,
• KGPROF=1: enables kernel profiling, which tracks time spend in each of kernel's functions,
• LLVM if set to 0 GNU toolchain (gcc & binutils) will be used to compile the project instead of LLVM toolchain (clang & lld).

If you need to debug build system, i.e. print commands executed by make as they are run, add VERBOSE=1 to the command line.

Important! It's recommended to issue make distclean command after each modification to config.mk file.
