# ref/ -- the reflection library.
#
# reflect.cpp holds C++ functions that read the engine's OWN registries and
# character tables and return Klammertext (a "@table" call and such), which
# the .kt fragments in this directory then render for whichever target is
# in force.  They are reached through "@eval :cpp", so this builds a DSO
# loaded at run time, not part of the shared library: reflect.so, on
# Windows reflect.dll (makefile.env's DSO).
#
# Adapted from sks/document/Makefile.  Two things differ and both matter:
# ref/ has no sks dependencies (a generator returns Klammertext, so it
# needs none of kutil/target's markup helpers), and it sits ONE level below
# $(KLAMMERTEXT_HOME) rather than two, which changes the rpath.

K := $(KLAMMERTEXT_HOME)

include $(K)/env/makefile.env

# CPPFLAGS already carries -I$(KLAMMERTEXT_HOME)/mac, which is every header
# reflect.cpp includes (machine, character, error, show).  No local -I.

LIBDIR := $(K)/lib
LIBRARY := $(LIBDIR)/$(KLAMMERTEXT_LIBFILE)
REFLECT := reflect$(DSO)

# "../lib", not "../../lib": the DSO sits in $(K)/ref, so one level up
# reaches $(K)/lib.  (sks/document's needs two, which is what this was
# copied from -- a wrong rpath here shows up only at dlopen time, and only
# where the loading process does not already have the library.)
