[R-SIG-Mac] Can I safely edit the fortran compiler in Makeconf?

[Federico Calboli]

Hi,

I am trying to build this package from source:

https://github.com/timothyfrasier/related

I cannot do it because I have gfortran-4.9 (from hombrew’s gcc49 --enable-fortran) and 

/Library/Frameworks/R.framework/Versions/3.2/Resources/etc/Makeconf

lists 

 etc/Makeconf.  Generated from Makeconf.in by configure.
#
# ${R_HOME}/etc/Makeconf
#
# R was configured using the following call
# (not including env. vars and site configuration)
# configure  'CC=clang' 'CXX=clang++' 'OBJC=clang' 'F77=gfortran-4.8' 'FC=gfortran-4.8' 'CFLAGS=-Wall -mtune=core2 -g -O2' 'CXXFLAGS=-Wall -mtune=core2 -g -O2' 'OBJCFLAGS=-Wall -mtune=core2 -g -O2' 'FCFLAGS=-Wall -g -O2' 'F77FLAGS=-Wall -g -O2' '--with-system-zlib' '--enable-memory-profiling' 'CPPFLAGS=-I/usr/local/include -I/usr/local/include/freetype2 -I/opt/X11/include' '--x-libraries=/opt/X11/lib’
…

I always create a symlink to the gfortran-4.9 binary so it reads ‘gfortran’, for ease of deployment.

Can I edit Makeconfig so that it reads:

 etc/Makeconf.  Generated from Makeconf.in by configure.
#
# ${R_HOME}/etc/Makeconf
#
# R was configured using the following call
# (not including env. vars and site configuration)
# configure  'CC=clang' 'CXX=clang++' 'OBJC=clang' 'F77=gfortran' 'FC=gfortran’ <—*change to gfortran*

and be done with it?  will it break everything/anything/bite me in the ass at some point?

Best

F
