Running on Linux/OSX (Lee's notes)

What's on master isn't doesn't have a "REPL loop" so doesn't do anything. You'll want the version on branch jal-master. You'll need to check out the corresponding jal-master branches for ivory and tower, too.

After doing a stack build, run something like

stack exec test-tick-gen -- --src-dir="foo" --const-fold

to generate the C code for one of the tests.

For a particular example, in the generated makefile, you need to add a include directive to point to ev.h; I installed with brew, so I have -I/usr/local/Cellar/libev/4.22/include.

You'll also have to set the LIBRARY_PATH to locate libev.a. For example, I run

LIBRARY_PATH=/usr/local/Cellar/libev/4.22/lib make

Also, there are a couple of asserts in tower_init.c that'll fail due to assumptions about priorities on the Raspberry PI. Delete those.
