Question

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

using namespace std;

void hello() {
    cout << "Hello world, I'm a thread!" << endl;
}

int main(int argc, char* argv[]) {
    cout << "!!!Hello World!!!" << endl; // prints !!!Hello World!!!

    boost::thread thrd(&hello);
    thrd.join();
    return 0;
}

我确信上面的代码没有任何问题，因为我已在Microsoft Visual Studio Express Edition上测试过它。但它不能在Eclipse中编译。

我在Windows机器上执行此操作，我使用带有MinGW工具链的Eclipse Kepler，我使用此命令D:/tool/boost_1_54_0在此目录./b2 install --with-thread --libdir=stage/lib --includedir=stage/include --build-type=complete stage toolset=msvc中安装boost。我在boost_thread-vc110-mt-1_54部分配置了额外的包含目录，库路径和线程库，libboost_system-vc110-mt-1_54和Libraries (-l)（项目属性＆gt; C / C ++构建＆gt;设置＆gt; MinGW C ++ Linker＆gt; Libraries）？

这是编译的输出，你看到它的任何线索吗？

Answer 1

-llibboost_thread-vc110-mt-1_54

应该是

-lboost_thread-vc110-mt-1_54

我使用以下命令行选项boost_1.45为我工作

-IC:\MinGW\boost_1_45_0 -LC:\MinGW\boost_1_45_0\stage\lib -lboost_thread-mgw46-mt-1_45

Answer 2

首先在boost_1中运行bootstrap.bat mingw然后b2 toolset=gcc _ ## _ 0 /.

在一段时间之后，您应该最终得到一个包含boost_1_##_0/stage/lib（或类似名称）的已填充libboost_thread-mgw48-mt-1_55.a文件夹。

然后，您需要在项目属性中添加boost_1_##_0/stage/lib作为MinGW C ++链接器的库路径，并添加boost_system-mgw48-mt-1_55＆amp; boost_thread-mgw48-mt-1_55作为没有 lib 前缀和 .a 结尾的库。（顺序也可能很重要，如果不是，请先尝试系统）

如何在Eclipse中使用MinGW编译boost线程？
