You will need `bison` version >= 3.0, `flex` >= 2.5 and any C++11 compiler. You will need `bison` version >= 3.0 (Bison 2.5 requires manual intervention),
A makefile is provided and will compile the `mcc` executable. Compiling the `flex` >= 2.5 and any C++11 compiler. The build scripts are generated using
executable is a matter of: CMake. A typical Makefile-based build workflow would be:
mkdir build/
cd build/
cmake ..
make make
A patch is provided for compatibility with Bison 2.5. If you can't really During the Makefile generation, the build script will test the compiler for all

with:
make bison2 If your tools are installed in non-standard locations
