[R-SIG-Mac] checking whether the C compiler works... no

[Naresh Gurbuxani]

With some search on the internet, I was able to solve my problem with a small edit in Makevars file.  When installing data.table, I had added some lines to Makevars file.  These lines were pointing to clang.  The problem was fixed when it was changed to gcc.  

# My Makevars file new
# Successful installation of reshape2 package
VER=-11                                                                            
CC=gcc$(VER)                                                                       
CXX=g++$(VER) 

# My Makevars file old
# These lines were recommended by data.table installation
# Could not install reshape2 package
CC=$(LLVM_LOC)/bin/clang -fopenmp                                                
CXX=$(LLVM_LOC)/bin/clang++ -fopenmp 

Hope this will help some user,

The   C compiler aka clang is not the same as the C++ compiler. 

Why don’t you install the pre-compiled version.
