Question

首先，我在根目录中使用以下命令和文件设置了项目：

conan install ./ && cmake CMakeList.txt

conanfile.txt

[generators]
cmake

[requires]
boost/1.68.0@conan/stable

[options]
boost:shared=True

[imports]

CmakeList.txt

cmake_minimum_required(VERSION 3.10)
project(app CXX)

include(conanbuildinfo.cmake)
conan_basic_setup()

set(CMAKE_C_FLAGS  "${CMAKE_C_FLAGS} -Wall")
add_definitions("-std=c++11")

add_executable(app src/main.cpp)

target_link_libraries(app ${CONAN_LIBS})

一切正常，直到我尝试使用make编译项目为止。这是我的main.cpp

#include <boost/archive/text_oarchive.hpp>
#include <boost/archive/text_iarchive.hpp>
#include <boost/serialization/string.hpp>
int main(int ac, char *args[]) {
    std::ofstream ofs("test");
    boost::archive::text_oarchive writer(ofs);
}

编译时，即时通讯收到未定义的引用：

CMakeFiles/app.dir/src/main.cpp.o : in function « void boost::archive::save_access::save_primitive<boost::archive::text_oarchive, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > >(boost::archive::text_oarchive&, std::__cxx11::basic_string<char, std::char_traits<char>, std::allocator<char> > const&) » :

collect2: error: ld returned 1 exit status

我不知道此错误的根源。编译器？图书馆链接？很奇怪，因为我可以使用boost的其他功能，它不能仅用于boost序列化...

/！\这不是重复的，目的是要了解为什么柯南不链接应该链接的Boost.Serialization。

使用Conan和Cmake对Boost Archive的未定义引用
