code块，MinGW的，升压和静态连接问题 [英] Code Blocks, MinGW, Boost, and static linking issues

问题描述

我使用的使用MinGW code块，我试图得到一个简单的程序来编译静态链接。我已经建立了使用这些路线 Boost库。一切工作正常，我能够成功编译这个简单的程序（汇编，我知道这是行不通的，因为它是退出发送到控制台的消息之前，但我只是希望它编译）。

如果我在链接库中有一个DLL，它编译罚款，但是当我有相同内容的静态.A库打开它，我得到了一个未定义的引用，如未定义参考`_imp ___ ZN5boost6threadD1Ev|

我不知道是什么问题，不能找到解决方案。我想这可能与连接器设置做的，但我不能找到如何更改这些信息。我将是可以提供的任何帮助非常感激。

 的#include＆LT;＆iostream的GT;
＃包括LT＆;升压/ thread.hpp＆GT;无效MyFunction的（）
{
    性病::法院LT＆;＆LT; 这是一个线程＆LT;＆LT;的std :: ENDL;
    返回;
}诠释的main（）
{
    提高::线程MyThread的（安培; MyFunction的）;
    返回0;}
 

解决方案

这是一个从尝试时，头被配置为一个动态链接静态链接。我解释一下这个在<一个libssh href=\"http://stackoverflow.com/questions/3704374/linking-error-lnk2019-in-msvc-unresolved-symbols-with-imp-$p$pfix-but-should/3714112#3714112\">this问题。在升压/线程/细节/ config.hpp 闲逛让我觉得你应该的#define BOOST_THREAD_USE_LIB ，或使用 -D 标记来这样做。

I am using Code Blocks with MinGW and am trying to get a simple program to compile with static linking. I have built the Boost libraries using these directions. Everything worked out fine and I was able to successfully compile this simple program (it compiles, I know it doesn't work because it exits before the message is sent to the console, but I just want it to compile).

If I have a DLL in my linker libraries, it compiles fine, but when I switch it with the static .a libraries of the same contents, I get undefined references such as "undefined reference to `_imp___ZN5boost6threadD1Ev'|".

I have no idea what the problem is and can't find the solution. I think it might have to do with linker settings but I can't find information on how to change them. I would be extremely grateful for any help that could be provided.

#include <iostream>
#include <boost/thread.hpp>

void myfunction()
{
    std::cout << "this is a thread" << std::endl;
    return;
}

int main()
{
    boost::thread mythread(&myfunction);
    return 0;

}

解决方案

It's from trying to link statically when the headers are configured for a dynamic link. I explain this for libssh in this question. Poking around in boost/thread/detail/config.hpp makes me think you should #define BOOST_THREAD_USE_LIB, or use the -D flag to do the same.
