## This Makefile is __very__ barebones
##
## It works on Debian/Ubuntu. On other systems, add -I and -L flags as needed.
## comment this out if you need a different version of R,
## and set set R_HOME accordingly as an environment variable
R_HOME := $(shell R RHOME)
## include headers and libraries for R
RCPPFLAGS := $(shell $(R_HOME)/bin/R CMD config --cppflags)
RLDFLAGS := $(shell $(R_HOME)/bin/R CMD config --ldflags)
RBLAS := $(shell $(R_HOME)/bin/R CMD config BLAS_LIBS)
RLAPACK := $(shell $(R_HOME)/bin/R CMD config LAPACK_LIBS)
## if you need to set an rpath to R itself, also uncomment
#RRPATH := -Wl,-rpath,$(R_HOME)/lib
## include headers and libraries for Rcpp interface classes
RCPPINCL := $(shell echo 'Rcpp:::CxxFlags()' | $(R_HOME)/bin/R --vanilla --slave)
RCPPLIBS := $(shell echo 'Rcpp:::LdFlags()' | $(R_HOME)/bin/R --vanilla --slave)
## include headers and libraries for RInside embedding classes
RINSIDEINCL := $(shell echo 'RInside:::CxxFlags()' | $(R_HOME)/bin/R --vanilla --slave)
RINSIDELIBS := $(shell echo 'RInside:::LdFlags()' | $(R_HOME)/bin/R --vanilla --slave)
## minimal Boost libs -- works for me on Ubuntu, may need -L switches elsewhere...
BOOSTLIBS := -lboost_thread
## compiler etc settings used in default make rules
CXX := $(shell $(R_HOME)/bin/R CMD config CXX)
CPPFLAGS := -Wall $(shell $(R_HOME)/bin/R CMD config CPPFLAGS)
CXXFLAGS := $(RCPPFLAGS) $(RCPPINCL) $(RINSIDEINCL) $(shell $(R_HOME)/bin/R CMD config CXXFLAGS)
