Hi Antony, Thank you for taking a look at this. I've added the lexical_cast_error.txt file to https://github.com/goedman/clang11-spirit-qi , in the Boost_lexical_cast directory. In the makefile we set: CC = clang++ -ftemplate-depth=256 -std=c++11 -stdlib=libc++ It only happens in the c++11 + clang++ 3.4 case. Regards, Rob J.

Hi,

Has anyone tried boost::lexical_cast<> on clang++ based on llvm/clang++ 3.4? Or is it too early to use 3.4?

Couldn't find any recent references to problems with lexical_cast (except from Mar 16, 2013 and older, but boost_1_54_0 does have that fix in it).

Are you using clang-3.4 with libc++ or are you using GCC's Standard Library?

...

No problems with llvm/clang++ 3.3, but on a test machine under 3.4 it produces the errors shown in below file lexical_cast-error.txt.

Did not get the lexical_cast-error.txt. Can you send it once more or put into git?

Thanks Antony, We'll try that (as soon as the next release is out of the door!) Regards, Rob J. Goedman goedman@icloud.com On Sep 16, 2013, at 2:28 AM, Antony Polukhin wrote:

Try adding the -lc++abi library during linking.

Also try adding the -nostdinc++ flag while compiling the sources and -nodefaultlibs while linking. (I've get all the info from here http://libcxx.llvm.org/ )
