Current project uses CMake system for building application. You can build compiler by your platform, using the following commands:
mkdir Build
cd Build
cmake ..
List of arguments for compilation:
Program usage:
-h [ --help ] Show help message.
-i [ --input ] arg Input source file.
-o [ --output ] arg Output executable file.
Example of usage compiler:
./Compiler -i SourceFile.as -o ExecutableFile
