我将 Boost C++ 库用于我的 Objective-C 项目。我按照此说明为 Xcode 添加了增强功能：http://freddy.cellcore.org/post/79587278354/boost-c-libraries-on-osx-xcode-5 添加 boost.framework 后，我可以正确地包含标题。

#include <boost/archive/text_iarchive.hpp> 
#include <boost/archive/text_oarchive.hpp>
#include <boost/serialization/map.hpp>
#include <boost/filesystem.hpp>
#include <boost/filesystem/fstream.hpp>

但是当我添加如下几行代码时，按构建，它会显示上面的错误。

std::map<int64_t, int64_t> foo;
boost::filesystem::path myFile = boost::filesystem::current_path() / "myfile.dat";

if (filesystem::exists(myFile))

    filesystem::ifstream ifs(myFile/*.native()*/);
    archive::text_iarchive ta(ifs);

    ta >> foo; // foo is empty until now, it's fed by myFile

    std::cout << "Read " << foo.size() << " entries from " << myFile << "\n";
 else 
    for (int i=0; i<100; ++i) foo[i] = 10;
    filesystem::ofstream ofs(myFile/*.native()*/);
    archive::text_oarchive ta(ofs);

    ta << foo; // foo is empty until now, it's fed by myFile
    std::cout << "Wrote " << foo.size() << " random entries to " << myFile << "\n";

我该如何解决这个问题？

【参考方案1】：

我无法再访问那个 Github 页面，但我猜你只有 x86 版本，而不是 x64 版本。

Try this...

来自脚本：

# To configure the script, define:
#    BOOST_LIBS:        which libraries to build
#    IPHONE_SDKVERSION: iPhone SDK version (e.g. 5.1)
#
# Then go get the source tar.bz of the boost you want to build, shove it in the
# same directory as this script, and run "./boost.sh".

或者你可以试试这个版本？是预编译... https://github.com/danoli3/ofxiosBoost

【讨论】：

很遗憾，您提供的链接正是我在问题中添加的链接。

您在构建时将 BOOST_LIBS 设置为什么？以及哪个来源 tar.bz？

我只是在构建框架时保留shell脚本，它下载1.56.0

我编辑了我的答案 - iOS 有一个预编译的 64 位版本

非常感谢！我缺少将序列化放入 BOOST_LIBS
