Question

我将应用程序移植到Windows上，并发现当跨越DLL边界中断boost :: thread时，线程不会被中断。

boost库是静态链接的，使用调试运行时和链接到共享运行时库的多线程支持构建。 / MDD

该项目使用msvc12（2013）编译（与编译boost相同的编译器）。

我做了一个简短的示例项目，演示了这个问题：

TEST.CPP

#include <iostream>

#include "boost/thread.hpp"
#include "test_library.h"
#include <iostream>
int main()
{
  qDebug() << "Hello";

  Test_library test;

  qDebug() << "Starting thread";
  boost::thread thread = boost::thread(&Test_library::Loop, &test);
  boost::this_thread::sleep_for(boost::chrono::seconds(3));

  qDebug() << "interrupt thread";
  thread.interrupt();

  qDebug() << "Joining thread";
  thread.join();

  qDebug() << "Closing Program";
  return 0;
}

test_library.cpp

#include "test_library.h"
#include "boost/thread.hpp"


void Test_library::Loop()
{

  qDebug() << "Starting loop";
  while(true)
  {
    qDebug() << "Looping";
    boost::this_thread::interruption_point();
    boost::this_thread::sleep_for(boost::chrono::milliseconds(500));
  }

  qDebug() << "Looping finished";
}

test_library.h

#pragma once
#include "test_library_global.h"
#include <QtCore>

class TEST_LIBRARYSHARED_EXPORT Test_library
{
public:
  void Loop();
};

TestProject.pro（QMake文件）

DESTDIR = ../TestProjectDeploy/

SOURCES += \
    test.cpp


LIBS += -L$$DESTDIR -ltest_library


include(../BoostIncludes.pri)

DESTDIR = ../TestProjectDeploy/

QT       -= gui

TARGET = test_library
TEMPLATE = lib

DEFINES += TEST_LIBRARY_LIBRARY

SOURCES += test_library.cpp

HEADERS += test_library.h

TestLibrary.pro

include(../BoostIncludes.pri)

DESTDIR = ../TestProjectDeploy/

QT       -= gui

TARGET = test_library
TEMPLATE = lib

DEFINES += TEST_LIBRARY_LIBRARY

SOURCES += test_library.cpp

HEADERS += test_library.h\
        test_library_global.h

unix {
    target.path = /usr/lib
    INSTALLS += target
}

BoostIncludes.pri

win32:INCLUDEPATH += "C:/Libraries/boost_1_60_0/" 

LIBS = "-LC:/Libraries/boost_1_60_0/stage/lib/"  \
"C:/Libraries/boost_1_60_0/stage/lib/libboost_thread-vc120-mt-gd-1_60.lib" \
"C:/Libraries/boost_1_60_0/stage/lib/libboost_system-vc120-mt-gd-1_60.lib" \
"C:/Libraries/boost_1_60_0/stage/lib/libboost_chrono-vc120-mt-gd-1_60.lib" \
"C:/Libraries/boost_1_60_0/stage/lib/libboost_timer-vc120-mt-gd-1_60.lib" \

节目输出：

Hello
Starting thread
Starting loop
Looping
Looping
Looping
Looping
Looping
Looping
interrupt thread
Looping
Joining thread
Looping
Looping
Looping

此问题是由于未动态链接到boost线程dll。所有项目中都需要预处理器宏

DEFINES += BOOST_THREAD_USE_DLL


################### WINDOWS ###################
WINDOWS_BOOST_DEBUG_DLL = "-LC:/Libraries/boost_1_60_0/stage/lib/"  \
-l"boost_system-vc120-mt-gd-1_60"\
-l"boost_chrono-vc120-mt-gd-1_60"\
-l"boost_thread-vc120-mt-gd-1_60"\
-l"boost_timer-vc120-mt-gd-1_60"\

跨越DLL边界时，Boost线程中断不起作用
