[Rcpp-devel] building shared library error with sourceCpp

[Fatima Batool]

Hi Drik and Simon,

thanks you for the help!

I have followed all the instructions Drik mentioned here:
*https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos/
<https://thecoatlessprofessor.com/programming/cpp/r-compiler-tools-for-rcpp-on-macos/>*
and then run a hello world.cpp example but unfortunately the error is still
there.

Error in
Rcpp::sourceCpp("/Users/fatimabatool/documents/New/Rcodes/ASW/helloworld.cpp")
:
  Error 1 occurred building shared library.

Have removed old installation files, installed command line tools, upgraded
to clang-7 and gfotron6.1. I have added set of compilation files to
~/.R/Makevars
 as mentioned and the file exist there (attached) but there is still no
CommandLineTools directory in Library/Developer. Should I try to create
these myself?

Best wishes,
Fatima
