[Rcpp-devel] Why would sourceCpp using both clang and gcc?

[Thell Fowler]

Ubuntu precise with clang 3.3 and gcc 4.6.3 with R 2.15.2 and Rcpp 0.10.1
when calling sourceCpp gives output I'm not quite understanding...

>
sourceCpp("~/src/TestPackageDepends2/inst/examples/CallFunction.cpp",verbose=T,
rebuild=T)

Generated Rcpp module declaration:
--------------------------------------------------------

#include <Rcpp.h>
RCPP_MODULE(sourceCpp_12634) {
    Rcpp::function("callFunction", &callFunction, Rcpp::List::create());
}

Building shared library
--------------------------------------------------------

DIR: /tmp/RtmpWMdYuo/sourcecpp_6275273d958b

/usr/lib/R/bin/R CMD SHLIB -o 'sourceCpp_12634.so' --preclean
'CallFunction.cpp'
"clang++" -I/usr/share/R/include -DNDEBUG
 -I"/home/thell/R/library/Rcpp/include"
-I"/home/thell/R/library/TestPackageDepends/include"   -fpic  -O3 -pipe  -g
 -c CallFunction.cpp -o CallFunction.o
g++ -shared -o sourceCpp_12634.so CallFunction.o
-L/home/thell/R/library/Rcpp/lib -lRcpp
-Wl,-rpath,/home/thell/R/library/Rcpp/lib -L/usr/lib/R/lib -lR


What would make clang _not_ get used for both phases?  My Makevars shows

CC="clang"
CXX="clang++"
CPP="clang-cpp"
