On macbook pro, OS X 10.11 El Capitan, Xcode 7.0.1 installed:
re-0.4.13 make fails with:

clang: error: linker command failed with exit code 1 (use -v to see invocation)

make CC=clang produces same results. Am I doing it wrong?

you can install baresip from Homebrew or Macports:

$ sudo port install baresip

or

$ brew install baresip

if you want to build from Source you need to install Xcode Command-Line tools.

Installed command-line tools and built as expected. Thank you.
