我用 lib-boost 编写了一个简单的代码来加载一个 CSV 文件。编译后出现以下错误：

Undefined symbols for architecture arm64:
  "boost::iostreams::mapped_file_source::init()", referenced from:
      boost::iostreams::mapped_file_source::mapped_file_source<std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > >(std::__1::basic_string<char, std::__1::char_traits<char>, std::__1::allocator<char> > const&, unsigned long, long) in class_map.cpp.o

ld: symbol(s) not found for architecture arm64

我使用自制软件安装了 boost，它包含在 cmakelist 中。

Found Boost: /opt/homebrew/lib/cmake/Boost-1.75.0/BoostConfig.cmake (found version "1.75.0") found components: system filesystem

【解决方案1】：

我发现这是一个 cmake 配置问题。我必须添加iostreams。

find_package(Boost REQUIRED COMPONENTS system iostreams)

target_link_libraries(program pthread z expat bz2 ${Boost_LIBRARIES})
