Thank you for downloading Boost Statechart viewer. Source files are located in the directory src. To compile them, simpy type make If you want to use different clang/llvm version, create a file called Makefile.config in this directory and add there one line: LLVM_CONFIG := where you have your llvm bin files/llvm-config This program was tested with LLVM/Clang 2.8. Enjoy using it.
