Well somehow I managed to compiled it with CXXFLAGS="-std=c++11 -stdlib=libc++" and linked libobjc (with Objective-C++ support) against libc++ (LLVM's C++11 standard library), that is I made a huge hump of libraries, libobjc2, libdispatch and LLVM's libc++ all linked together.
I always use libobjc2 in place of libBlocksRuntime hence libobjc2 and libdispatch always link against each other, and now libobjc2 links against libc++ too and since libc++ linked against libdispatch, that dragged libobjc2 in, and by doing that, clang is involved too by linking against libc++ and using C++11 features, so does lldb. What a mess... 在 2013-5-21，下午9:21，David Chisnall <[email protected]> 写道： > On 21 May 2013, at 12:16, Chan Maxthon <[email protected]> wrote: > >> When I tried to compile libobjc2 trunk or 1.7rc1 on Ubuntu server using >> clang 3.4 svn, clearly the objc++ part is calling for c++11 > > No, it isn't.
