I can not find any documentation on this. It all works -- using the supplied Makefile. You chose not to use it, you need to 'port' it to your preferred build tool. The relevant lines are LDLIBS := $(RLDFLAGS) $(RRPATH) $(RBLAS) $(RLAPACK) $(RCPPLIBS) $(RINSIDELIBS) as well as all the lines filling the variables uses here. When I build first example, it ends up being (and note that paths etc depend on local installations) edd@max:~/svn/rinside/pkg/inst/examples/standard$ make rinside_sample0 g++ -I/usr/share/R/include -I/usr/local/lib/R/site-library/Rcpp/include -I"/usr/local/lib/R/site-library/RInside/include" -O3 -pipe -g -Wall rinside_sample0.cpp -L/usr/lib64/R/lib -lR -lblas -llapack -L/usr/local/lib/R/site-library/Rcpp/lib -lRcpp -Wl,-rpath,/usr/local/lib/R/site-library/Rcpp/lib -L/usr/local/lib/R/site-library/RInside/lib -lRInside -Wl,-rpath,/usr/local/lib/R/site-library/RInside/lib -o rinside_sample0 edd@max:~/svn/rinside/pkg/inst/examples/standard$ You could always use make if the Eclipse build tool cannot be tamed...
