Compile boost C++11 clang mac cannot find cstddef

Question

I cannot compile boost with clang 3.1 on Mac os x 10.8.2.

This is what I did:

./bootstrap.sh --with-toolset=clang
./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++"

I also tried without chrono, test, wave and signals. I tried a user-config.jam with

using clang-darwin

This is the error I have for almost every file:

/boost/config/select_stdlib_config.hpp:18:12: fatal error: 'cstddef' file not found

It is kind of similar to How to compile/link Boost with clang++/libc++?

Thank you :-)

Update: I do have the latest Xcode 4.5.2 with the command line tools installed.

Here is part of the console output:

Kikohs:trunk kikohs$ ./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++"

Answer 1

For Ubuntu 16.04, I'm able to build boost with c++11 using gcc:

cd /home/user/install/boost/boost_1_54/

./bootstrap.sh --with-toolset=gcc

./b2 toolset=gcc cxxflags="-std=c++11 -I/usr/include/c++/5/ -I/usr/include/x86_64-linux-gnu/c++/5/"

mkdir ../2

./b2 install --prefix=../2/

The command for building my program:

g++ -std=c++11 -O2 fprint.cpp -o fprint -I/home/user/install/boost/2/include/ -L/home/user/install/boost/2/lib/ -lboost_regex -lboost_program_options

Before that the command was:

g++ -std=c++11 fprint.cpp -o fprint -lboost_regex -lboost_program_options

, but this old command (that worked before well with older OS and boost/etc) doesn't work anymore saying errors " undefined reference to boost::re_detail_106501 " (said by /tmp/cc0Zn8lo.o: In function `bool boost::regex_search...)

((also if I don't use "-I/usr/include/c++/5/ -I/usr/include/x86_64-linux-gnu/c++/5/" for ./b2, then the error is "cannot find cstddef" during building boost, so exactly the same like the subject of this ticket))

Answer 2

I finally fixed my problem after many hours.

Homebrew was messing with my path and for some reason my clang could not find the libc++ headers.

There is a bug is boost 1.52.

See Boost numeric limits bug

I had to edit the file :

boost/config/stdlib/libcpp.hpp

and patch it:

#if _LIBCPP_VERSION < 1002 
#   define BOOST_NO_CXX11_NUMERIC_LIMITS 
#endif 

Now boost is building properly ...

It looks like you forgot to install the libc++ headers alongside clang.

If you don't want to mess with installing the headers, try the version of clang distributed by Apple as part of the Command Line Tools package; it's been through more testing, and it's already set up properly.
