forcing the use of the c++ linker with c++ and fortran sources
I'm trying to build a package which has both gfortran and c++ code. In my installation of R, the R CMD INSTALL process compiles each c++ and gfortran code with the correct compiler, but performs the link step with "gfortran" and this creates undefined symbols at load time. How does one override/force the use of a different command in the link step? Is there an appropriate entry in Makevars that will do the trick? Thanks, -sg
