I was trying the provided CLING executable from your nightly build, namely cling-MacOSX-10.8-64bit-4d98a76dec.
On First run I am getting:
ERROR in cling::CIFactory::createCI():
Possible C++ standard library mismatch, compiled with __GLIBCXX__ v20070719 but cannot extract standard library version from current compiler clang++
input_line_1:1:10: fatal error: 'cling/Interpreter/RuntimeUniverse.h' file not found
#include "cling/Interpreter/RuntimeUniverse.h"
^
Assertion failed: (clingAtExit && "cling_cxa_atexit must exist."), function remapCXAAtExit, file /ec/build/cling-4d98a76decae-full-1247013/cling-src-4d98a76decaefccfabdbcc9a73b124ecbe93260d/tools/cling/lib/Interpreter/ExecutionContext.cpp, line 57.
Illegal instruction: 4
So I have copied cling includes in /usr/local/include, the include error has disappeared but now I get:
ERROR in cling::CIFactory::createCI():
Possible C++ standard library mismatch, compiled with __GLIBCXX__ v20070719 but cannot extract standard library version from current compiler clang++

My configuration is OSX 10.9 Mavericks with Xcode 5.0.2 installed (not sure if it affects anything, I am actually “starting” to understand how cling works )
Any hints?
the build is successful but running the resulting cling yields:

So I’ve added path to wchar.h for 10.9 sdk but still getting errors on the linker.
