Question

我已经在linux下使用boost一段时间了，但我很快就会开始研究Windows项目，所以我决定为Windows设置Boost，并让它与QtCreator一起工作（也在linux下工作））。

所以，下载并构建了windows boost libs并前往QtCreator在windows下试用它们，我感到有些困惑。

的main.cpp

#include <iostream>
#include <vector>

#include <boost/timer/timer.hpp>

using namespace std;

vector<int> f();

int main()
{
    cout << "Hello World!" << endl;

    vector<int> r;
    {
        boost::timer::auto_cpu_timer ct;
        r = f();
    }
    return 0;
}

vector<int> f() {
    vector<int> result;

    for (auto i = 0U; i < 10000; i++) {
        result.push_back(i);
    }
    return result;
}

test.pro

TEMPLATE = app
CONFIG += console
CONFIG -= app_bundle
CONFIG -= qt

SOURCES += main.cpp

DEFINES += BOOST_ALL_NO_LIB
INCLUDEPATH+= C:/boost/boost_1_57_0/
LIBS += -L$$quote(C:\boost\boost_1_57_0\stage\lib) -llibboost_timer-vc120-mt-1_57 -llibboost_system-vc120-mt-1_57

include(deployment.pri)
qtcAddDeployment()

现在，我已尝试了很多关于libs和＆＃39;定义＆＃39;是最近的，但每次，我都会得到未解决的符号问题：

main.obj : error LNK2019: unresolved external symbol "class boost::system::error_category const & __cdecl boost::system::system_category(void)" (?system_category@system@boost@@YAAEBVerror_category@12@XZ) referenced in function "void __cdecl boost::system::`dynamic initializer for 'native_ecat''(void)" (??__Enative_ecat@system@boost@@YAXXZ)

main.obj : error LNK2019: unresolved external symbol "public: __cdecl boost::timer::auto_cpu_timer::~auto_cpu_timer(void)" (??1auto_cpu_timer@timer@boost@@QEAA@XZ) referenced in function main

现在，从我所读过的内容来看，似乎我不应该甚至不必说明从哪个库中导入...但这也不起作用。

编辑：尝试为链接器设置/ VERBOSE标志，它非常奇怪;突出的一点是：

所以，显然它找到并查看.lib文件，甚至注意到我要求的libs的额外包含，但没有找到要链接的代码对象。

可能与在Windows 64上有关？我假设boost会在这里构建为x64，但也许不会。有人建议尝试预先建立的二进制文件，将会查找它们。

Answer 1

好吧，事实证明我在Windows下对Boost的构建过程有太多的假设，需要告诉它是否在64位机器上。将库重建为64位，现在编译好了。

感谢民间的建议。

Boost，Windows和QtCreator
