# ImplicitCAD Makefile. Build and test Implicitcad.

# This is the Makefile for when you are running a version of cabal-install less than version 1.24.

## Locations of binaries used when running tests, or generating the images to go along with our README.md.
# The location of stl2ps, from stltools, available from https://github.com/rsmith-nl/stltools/tree/develop
stl2ps=/disk4/faikvm.com/stltools/stltools/stl2ps.py
# The location of convert, from imagemagick
convert=convert
# The location of GHC, used to compile .hs examples.
GHC=ghc
# The location of the created extopenscad binary, for running shell based test cases.
EXTOPENSCAD=dist/build/extopenscad/extopenscad
# The location of the implicitsnap binary, which listens for requests via http. The backend of the website.
IMPLICITSNAP=dist/build/implicitsnap/implicitsnap
# The location of the benchmark binary, for benchmarking some implicitcad internals.
BENCHMARK=dist/build/Benchmark/Benchmark
# The location of the parser benchmark binary, specifically for benchmarking implicitcad's parser.
PARSERBENCH=dist/build/parser-bench/parser-bench
# The location of the created test binary, for running haskell test cases.
TESTSUITE=dist/build/test-implicit/test-implicit
# The location of it's source.
TESTFILES=$(shell find tests/ -name '*.hs')
# The location of the documentation generator. for documenting (some of) the extopenscad language.
DOCGEN=dist/build/docgen/docgen

## Options used when calling ImplicitCAD. for testing, and for image generation.
# Enable multiple CPU usage.
# Use the parallel garbage collector.
# spit out some performance statistics.
RTSOPTS=+RTS -N -qg -t
# The resolution to generate objects at. FIXME: what does this mean in human terms? 
RESOPTS=-r 50

SCADOPTS?=-q

# Uncomment for profiling support. Note that you will need to recompile all of the libraries, as well.
#PROFILING= --enable-profiling

## FIXME: escape this right
# Uncomment for valgrind on the examples.
