C Compiler

Compiling

Linux:

You can build the source with a single command. Make sure you are in the root src directory, and type: "make all" This will build both the compiler and virtual machine. The resulting executables will be placed in the root binary folder for the project. The programs are named "c" for the compiler, and "cvm" for the virtual machine.

Example Programs/Tests

Once you have built the compiler and virtual machine, both executables are also copied to the bin folder under 'examples.' The example programs can be built in a similar fasion. Change directory to examples/ and execute a "make" call. That will build all the examples for execution. In this case however, the Makefile will use my C compiler to build the examples, and will produce VM executables in the bin folder under the examples folders.

Windows:

Not tested.

Usage:

To compile a source file, first make sure that it adheres to the small C subset that is specified in the Documentation file, as not all of C is implemented yet.

Once you have checked that off, locate the compiler and VM executable in the bin directory and change to that directory through the command line. Assuming you have a test file, say test.c, you could type in the following to compile the file:

$ ./c test.c -o test.vm

That would compile the c source and produce a virtual machine bytecode executable. To run that exectuable, type in the following:

$ ./cvm test.vm

That would execute the program.

You can display a help screen by typing in --help in either of the program's command line arguments, like so:

$ ./c --help

or

$ ./cvm --help
