You will need git installed. You will also need libxml2 and python3. If you use homebrew:
brew install git
brew install libxml2
brew install python
Download the the inform6-test repository and the various compiler and interpreter repositories.
git clone https://github.com/erkyrath/inform6-test.git
git clone https://github.com/erkyrath/remglk.git
git clone https://github.com/erkyrath/glulxe.git
git clone https://github.com/erkyrath/fizmo.git
git clone https://github.com/DavidKinder/Inform6
In the Inform6 directory:
cc -o inform *.c
cp inform ../inform6-test/inform
In the remglk directory:
make
In the glulxe directory:
Edit the Makefile: comment out the three ../cheapglk lines at the top; uncomment in the three ../remglk lines.
Then:
make
cp glulxe ../inform6-test/glulxer
In the remglk directory (if you haven't already):
make
In the fizmo directory:
Copy the attached config.mk file into the fizmo directory.
(Note that this config.mk looks for libxml2 in the location that homebrew installs it. If you have installed it elsewhere, you'll need to edit config.mk.)
Edit fizmo-glktermw/src/fizmo-glktermw/Makefile: on line 18, change -lglktermw to -lremglk.
Then:
make fizmo-glktermw
cp ./fizmo-glktermw/fizmo-glktermw ../inform6-test/fizmor
In the inform6-test directory:
git submodule init
git submodule update
python3 dotest.py --compiler ./inform --terp ./glulxer dm4/*.inf
python3 dotest.py -Z --compiler ./inform --terp ./fizmor dm4/*.inf
The second line (the Z-code tests) will fail once, on dm4/ex42.inf. This example uses the Glulxe opcode for deterministic RNG. It does not compile for Z-code.
