Question

我正在使用QWidget开发一个小型应用程序并静态链接Qt 5.6。我现在正在使用VS12。

#include <QMainWindow>
#include <QApplication>

int main(int argc, char *argv[])
{
  QApplication a(argc, argv);
  QMainWindow w;
  w.show();

  return a.exec();
}

它编译得很好，但我收到链接器错误。

我已经包含以下库：

winmm.lib
imm32.lib
Ws2_32.lib
opengl32.lib
Qt5Guid.lib
Qt5Widgetsd.lib
qtpcred.lib
qtharfbuzzngd.lib
Qt5PlatformSupportd.lib
qwindowsd.lib
libEGLd.lib
libGLESv2d.lib
qtfreetyped.lib
Qt5Cored.lib

有趣的是，如果使用QtCreator它编译，链接和运行就好了。我看到的是QtCreator添加了以下编译标志：

-DQT_WIDGETS_LIB -DQT_GUI_LIB -DQT_CORE_LIB -DQT_OPENGL_ES_2 -DQT_OPENGL_ES_2_ANGLE -DQT_OPENGL_ES_2_ANGLE_STATIC -DGL_APICALL= -DEGLAPI=

我在我的项目中尝试了它们，但它没有改变任何东西。我错过了什么？我需要做什么才能使程序链接？

Answer 1

我找到了。这是使其工作所需的库列表：

winmm.lib
imm32.lib
Ws2_32.lib
Qt5Guid.lib
Qt5Widgetsd.lib
qtpcred.lib
qtharfbuzzngd.lib
Qt5PlatformSupportd.lib
qwindowsd.lib
libEGLd.lib
libGLESv2d.lib
qtfreetyped.lib
Qt5Cored.lib
+ preprocessord.lib
+ translatord.lib
+ d3d9.lib
+ dxguid.lib

不需要opengl32.lib。我仍然不知道为什么QtCreator知道需要哪些库以及为什么VS2013不需要。谢谢你的帮助。

Answer 2

据我所知，链接器正在抱怨this line of code。查看what that file is including似乎表明依赖于libANGLE。

经过大量谷歌搜索，我发现了CreateTLS() seems to be defined in libANGLE common，可以找到here。

我不确定这些定义最终会在哪个特定的Lib或DLL中查找，但是查看构建脚本肯定会显示它（抱歉，我没时间做那个atm）< / em>的。但原始问题中的符号肯定是由libANGLE提供的一个Lib。

this page表示您需要做的就是将libEGLd.lib和libGLESv2.lib添加到链接器行，已经是这种情况，但您应该检查是否也有DLL 。注意第3点，quoted from the linked page，下面：



将libEGL.dll和libGLESv2.dll从构建输出目录（请参阅构建ANGLE）复制到应用程序文件夹中。


如果您将DLL添加到解决方案中，您可以automate copying them to the destination directory.。
