To compile the compiler you need the following packages:

• g++

  Check if it is installed with

  g++ version

  and if not installed, install with

  xcode-select --install

  This should install g++ to /usr/bin/g++ which is where cmake expects it to be. Make sure this is the case.

  This will install tons of useful packages, including g++.

• make

  Check if it is installed with

  make --version

  and otherwise install with

  xcode-select --install

  This will install tons of useful packages, including make.

• cmake

  Check if it is installed with

  cmake --version

  and otherwise install with

  brew install cmake

  (In case brew is not installed on your computer you can install it following the instructions here)

To compile first create a directory named build in the root and then run

cd build && cmake .. && make

This will create an executable named inslt.

After compiling make sure you are in the build directory. Use ./inslt to run the executable. It takes up to two arguments, the first one being the input file and the second one being an optional output name for the compiled program (defaults to a.out). For example you can run

./inslt ../tests/fibonacci.inslt my_output_file

to compile the file fibonacci.inslt located in the tests directory and name the resulting file my_output_file. That file can now be run with ./my_output_file.
