Seconded. That is actually what I do, including the better-than-awesome ccache: edd@max:~$ cat .R/Makevars # edd 03 Mar 2009 ## for C code CFLAGS=-g -O3 -Wall -pipe -pedantic -std=gnu99 #CFLAGS=-O3 -g0 -Wall -pipe -std=gnu99 ## for C++ code CXXFLAGS= -g -O3 -Wall -pipe -pedantic -Wno-variadic-macros #CXXFLAGS= -g0 -O3 -Wall -pipe -Wno-variadic-macros #CXXFLAGS= -O3 -g0 -Wall -pipe ## for Fortran code #FFLAGS=-g -O3 -Wall -pipe FFLAGS=-O3 -g0 -Wall -pipe ## for Fortran 95 code #FCFLAGS=-g -O3 -Wall -pipe FCFLAGS=-O3 -g0 -Wall -pipe CC=ccache gcc CXX=ccache g++ FC=ccache gfortran F77=ccache gfortran MAKE=make -j4 edd@max:~$ The -Wno-variadic-macros was once needed when Romain was a tad more aggressive in trying new C++0x features. The 'make -j4' also takes care of parallel builds.
