I tried this
## Use the R_HOME indirection to support installations of multiple R version
PKG_CPPFLAGS=-I/opt/boost_1_54_0/include -I../inst/include
PKG_LIBS=-L/opt/boost_1_54_0/lib -lboost_regex `$(R_HOME)/bin/Rscript -e
"Rcpp:::LdFlags()"`
and this:
## Use the R_HOME indirection to support installations of multiple R version
PKG_CPPFLAGS=-I/opt/boost_1_54_0/include -I../inst/include
PKG_LIBS = -L/opt/boost_1_54_0/lib -lboost_regex `$(R_HOME)/bin/Rscript -e
"Rcpp:::LdFlags()"`
Still got

Good start!

Those have to be __two distinct lines__ not one glued together. Try
PKG_CPPFLAGS=-I/opt/boost_1_54_0/include -I../inst/include
PKG_LIBS = -L/opt/boost_1_54_0/lib -lboost_regex `$(R_HOME)/bin/Rscript -e
"Rcpp:::LdFlags()"`
ie one assignment each to two variables PKG_CPPFLAGS and PKG_LIBS.
| 3. Change rcpp_hello_world.cpp to this:
Looks good, and should work. Boost Regex use is a nice small example.
