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. 2013/10/18 <cln-list-request@ginac.de>

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
