编译boost :: program_options的示例代码:http://svn.boost.org/svn/boost/trunk/libs/program_options/example/first.cpp
...在MacOS Lion(10.7.2)上,使用随MacPorts安装的boost-1.48.0:
$ clang++ -v
Apple clang version 3.0 (tags/Apple/clang-211.12) (based on LLVM 3.0svn)

$ clang++ -std=c++0x --stdlib=libc++ -lc++ -I/opt/local/include -L/opt/local/lib -lboost_program_options first.cpp -o first

这就是我做的:
./bootstrap.sh --with-toolset=clang
./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++"
我也试过没有计时,测试,波动和信号.我尝试了一个user-config.jam
using clang-darwin
这是我几乎每个文件都有的错误:
/boost/config/select_stdlib_config.hpp:18:12: fatal error: 'cstddef' file not found
它有点类似于如何用clang ++/libc ++编译/链接Boost？
谢谢 :-)
更新:我确实安装了最新的Xcode 4.5.2并安装了命令行工具.
这是控制台输出的一部分:
Kikohs:trunk kikohs$ ./b2 toolset=clang cxxflags="-std=c++11 -stdlib=libc++" linkflags="-stdlib=libc++"

首先,我正在使用其他一些库,例如openssl,而clang抱怨我在构建库时没有解决某些符号.它们不应该是:这些库将与最终的二进制文件链接,它不应该发生在中介上.
然后,还有一些方法和变量应该在"客户端"二进制文件中实现...使用GCC,没有问题,但Clang也抱怨这些符号在编译期间无法解决.
怎么会 ？我该怎么办 ？
这是我的CMakeLists.txt,以防有用:
cmake_minimum_required(VERSION 2.8)
project(crails_project)
set(CMAKE_CXX_FLAGS "-std=c++0x -Wall -Wno-deprecated-declarations -pedantic -DASYNC_SERVER -DSERVER_DEBUG -DUSE_MONGODB_SESSION_STORE")
find_package(cppnetlib REQUIRED)
include_directories(include /usr/local/include ${CPPNETLIB_INCLUDE_DIRS} .)
file(GLOB crails_core
src/*.cpp)
file(GLOB crails_sql
src/sql/*.cpp)
file(GLOB crails_mongodb
src/mongodb/*.cpp)
add_library(crails-core SHARED ${crails_core})
add_library(crails-sql SHARED ${crails_sql})
add_library(crails-mongodb SHARED ${crails_mongodb})
这是崩溃的命令:

以下是我得到的两种错误:

第二个:

./b2 clean
./b2 toolset=clang cxxflags="-stdlib=libc++" linkflags="-stdlib=libc++"
我在Scientific Linux 6.4 x86_64主机上测试了上述提示,它"主要"用于构建完整的Boost 1_53_0发行版,使用clang++ 3.3sv和libc++ 3.3svn.我大多说,因为我真的想删除所有的libstdc++依赖.
不过,以下内容:
libboost_graphlibboost_localelibboost_regex仍显示libstdc++依赖关系(ldd输出使其非常明显).我想知道一个很好的方法来删除这样的,并会欣赏任何提示.
我在macos mavericks上从自制软件安装了1.55.0增强版.获取链接器异常 - 找不到std :: string :: c_str(),我不明白为什么.这可能是自制软件的问题吗？我尝试直接从boost编译boost 1.55.0,它甚至没有在macos上构建.
这一点代码:
#include <iostream>
#include <unordered_map>
#include <vector>
#include <boost/thread/tss.hpp>
typedef std::unordered_map<std::string, std::string> StringMap;
static boost::thread_specific_ptr<std::vector<StringMap*>> rlist;
int main()
{
return 0;
}
使用此命令行编译:
g++ -std=c++11 main.cpp -I/usr/local/include -L/usr/local/lib -lboost_thread -lboost_system -lboost_atomic -lboost_log -lstdc++
抛出此链接器异常:
