./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)

Hi,
I am currently trying to compile cln with linkage against libc++. My
aproach was:
/configure CXX=/usr/bin/clang++ CXXFLAGS=-stdlib=libc++
However this does not work as I get erroneus output such as
In file included from base/cl_alloca.cc:4:
In file included from ./base/cl_sysdep.h:56:
In file included from ./base/cl_macros.h:7:
../include/cln/exception.h:14:24: error: implicit instantiation of
undefined template 'std::__1::basic_string<char,
std::__1::char_traits<char>, std::__1::allocator<char> >'
: std::runtime_error(std::string()) {}
^
/usr/bin/../lib/c++/v1/iosfwd:187:28: note: template is declared here
class _LIBCPP_TYPE_VIS basic_string;
What does this mean and what am I doing wrong? I need this in order to
compile ginac with the same linkage as it is used in a project with c++11
features.
Best regards,
Stefan
