A few useful notes for compiling DGD

DGD's build process is very simple, and doesn't have a configure script. Platforms are detected in src/Makefile. You will need a C++ compiler and yacc or a yacc-compatible parser generator.

DGD can be compiled on Unix-like systems and on Windows. See src/host/win32/README.md for additional information regarding the Windows build.

There are a few things you can enable/disable by adding the proper defines to the Makefile on Unix systems, or to your project on Visual Studio.

• LARGENUM
  64 bit integers and floats.
• SLASHSLASH
  C++ style // comments in LPC code.
• SIMFLOAT Simulated floats. Not a macro but a argument for make, make SIMFLOAT=1.
• NOFLOAT
  Compile without using host floats (requires simulated floats).
• CLOSURES
  Function pointers, implemented as a builtin type. See doc/builtin.md for information about adding builtin types. CLOSURES allows taking the address of a function with &func(), and calling the function that a function pointer refers to with (*func)(). When creating a pointer to a function, function arguments may be included: &func("foo"). More function arguments can be added when the function is called, or in constructing a new pointer: &(*func)("bar")
