## Makefile rules for building Coqchk

## NB: For the moment, the build system of Coqchk is part of
## the one of Coq. In particular, this Makefile.checker is included in
## Makefile.build. Please ensure that the rules define here are
## indeed specific to files of the form checker/*

# The binaries

CHICKENBYTE:=bin/coqchk.byte$(EXE)
CHICKEN:=bin/coqchk$(EXE)

# The sources

CHKLIBS:= -I config -I clib -I lib -I checker

## NB: currently, both $(OPTFLAGS) and $(BYTEFLAGS) contain -thread

# The rules
