• Error when with Xcode 5.0 and Rcpp (Command Line Tools ARE installed) 3 answers

I upgraded my Mac OS X from ML to Maverick today, and installed the preview version of RStudio. I think I also updated Xcode to 5.0.1 and installed Command Line Tools on my MacBook Pro. However, when I install my own package from source, I got the following error:

* installing *source* package ‘PKG’ ...
** libs
llvm-gcc-4.2 -arch x86_64 -std=gnu99 -I/Library/Frameworks/R.framework/Resources/include -DNDEBUG  -I/usr/local/include    -fPIC  -mtune=core2 -g -O2  -c lm.c -o lm.o
make: llvm-gcc-4.2: No such file or directory
make: *** [lm.o] Error 1
ERROR: compilation failed for package ‘PKG’
* removing ‘/Library/Frameworks/R.framework/Versions/3.0/Resources/library/PKG’
* restoring previous ‘/Library/Frameworks/R.framework/Versions/3.0/Resources/library/PKG’
Warning in install.packages :
  installation of package ‘../PKG_0.2.7.tar.gz’ had non-zero exit status

Can I know if there is any solution to solve this issue? Thanks! Part of my sessionInfo:

R version 3.0.1 (2013-05-16)

Please refer to this link: https://stackoverflow.com/a/19505252/1510531. After modifying the following lines in the Makeconf file in /Library/Frameworks/R.framework/Resources/etc:

CC=clang
CXX=clang++
CXXFLAGS= -O3 -pedantic

I can now install R source packages :)

Update

According to @asieira, the last CXXFLAGS is not recommended, so just make the following changes:

CC=clang
CXX=clang++
