[CLN-list] CLN-list Digest, Vol 69, Issue 1

[Stefan Schupp]

I fixed my problem:

./configure CXX=/usr/bin/clang++ CXXFLAGS="-stdlib=libc++ -std=c++11"
LDFLAGS="-stdlib=libc++"

and then add an include for string (#include <string>) to exception.h
(should be considered a bug? Thanks to Howard Hinnant from Stackoverflow
for helping)

Now CLN compiles as expected.
