适用于建筑x86_64的升压X code C ++命令行未定义的符号 [英] Boost Xcode C++ command line Undefined symbols for architecture x86_64

问题描述

我已经成功地得到提振按照说明书的此处。我现在需要创建一个命令行应用程序生成许可证。我继承了这个code和它使用的提振。我想我已经正确设置好一切，但是当我尝试建立我收到的x86_64架构在未定义的符号错误的一切使用boost。

我创建了一个命令行应用程序：

我添加了助推的路径：

我甚至试图改变C ++标准库的编译器：

下面是一些code，其中我引用Boost库：

 的#include＆LT;升压/ DATE_TIME /了posix_time / posix_time_io.hpp＆GT;命名空间BG =的boost ::格利高;
命名空间BP =提振::了posix_time;
 

下面是错误的：

有没有人用得到提振成功打造一个命令行应用程序？如果是，那么可以请你帮忙吗？

感谢您。

解决方案

该问题可能是两个不同的问题造成的：

1. 您还没有链接的库propertly：

在构建阶段选项卡，在链接二进制与libaries补充：
libboost_program_options.a

<醇开始=2>

的另一个问题是你怎么样编译，当你安装了库连接的Boost库。

如果你想使用的libstdc ++，你应该推动建立这样的：

  ./ bootstrap.sh
./b2 CXXFLAGS = -  STDLIB = ++的libstdcLINKFLAGS = -  STDLIB = ++的libstdc
./b2安装 -  preFIX = YOURINSTALLATIONDIRECTORY
 

和再使用的libstdc ++以x code。

I have successfully gotten boost to work in a test application by following the instructions here. I now need to create a command-line application to generate licenses. I've inherited this code and it uses boost. I think I've set everything up correctly but when I try to build I receive the Undefined symbols for architecture x86_64 error for everything using boost.

I created a command-line application:

I added the path for boost:

I even tried to change the C++ Standard Library compiler:

Here is some code where I am referencing the boost library:

#include <boost/date_time/posix_time/posix_time_io.hpp>

namespace bg = boost::gregorian;
namespace bp = boost::posix_time;

Here are the errors:

Has anybody gotten a command-line application using boost to successfully build? If YES, then can you please help?

Thank you.

解决方案

The problem may be caused for two different problems:

1. You haven't linked the library propertly:

In "Build Phases" Tab, in "Link Binary with libaries" add: libboost_program_options.a

2. Another problem is how have you compiled and linked the boost library when you installed the library.

If you want to use libstdc++ you should build boost like this:

./bootstrap.sh
./b2 cxxflags="-stdlib=libstdc++" linkflags="-stdlib=libstdc++"
./b2 install --prefix=YOURINSTALLATIONDIRECTORY

And then use libstdc++ in xcode.
