Assignment 3 Discussion

You have to change 2 things in the Makefile. Here is one where you only change one thing:

PBRT_DIR = ../src-1.02
PBRT_BIN_DIR = $(PBRT_DIR)/bin


ARCH = $(shell uname)


ifneq ($(ARCH),Darwin)
DLLLIB = -ldl
endif

EXRINCLUDE=../OpenEXR/include
EXRLIBS=-lIlmImf -lImath -lIex -lHalf -lz

CXX=g++
OPT=-O2
INCLUDE=-I. -I$(PBRT_DIR)/core -I$(EXRINCLUDE)
WARN=-Wall
CWD=$(shell pwd)
CXXFLAGS=$(OPT) $(INCLUDE) $(WARN)
LIBS=$(LEXLIB) $(DLLLIB) -L$(EXRLIBDIR) $(EXRLIBS) -lm
ifeq ($(ARCH), Darwin)
  SHARED_LDFLAGS = -flat_namespace -undefined suppress -bundle -noprebind
  LRT_LDFLAGS=$(OPT) -L/sw/lib
  #PBRTPRELINK=-Wl,-all_load
  INCLUDE += -I/sw/include
  CXX=ccache g++
  EXRLIBDIR=../OpenEXR/lib-osx
  WARN += -Wno-long-double
else
  SHARED_LDFLAGS = -shared
  LRT_LDFLAGS=-rdynamic $(OPT)

  EXRLIBDIR=../cs348b_extras/lib

  PBRTPRELINK=-Wl,--export-dynamic -Wl,-whole-archive
  PBRTPOSTLINK=-Wl,-no-whole-archive
endif
LD=$(CXX) $(OPT)
