我正在尝试编译 Qt-Library osgQt，因为它没有在预编译包中提供(至少不支持 Windows 7(x64) 和 MSVS 11 - x64)。因此，我遵循这些说明:

Note: This library is part of OSG sources, but it is not part of prebuilt binaries. It is necessary to download whole OSG project to build osgQt library.

I. Download osg 3.0.1 sources.

II. Generate Visual Studio solution with CMake.

To do this you can run prepared batch file. - It creates VS solution without any osg dependencies. (hopefully sufficient) - It is necessary to set variables in the file header. - After running it, there should be build folder with OpenSceneGraph.sln file and src/osgQt directory.

我不能使用这个批处理文件，因为它不可用和其他软件条件(MSVS 2008，Qt 4.7.4)，因此我必须自己用 CMake 构建它。

III. Open OpenSceneGraph.sln in Visual studio

IV. Choose debug win32 (or other configuration you want)

V. Select osgQt project

VI. From menu select Build, Build osgQt

Result: osgQt lib and dll files ...copy them beside prebuilt osg libraries.

但是我在第二步遇到了麻烦:

使用 CMake 2.8.11.2 时，我收到以下错误:

CMake Error at D:/Programme/QT/5.1.0/msvc2012_64_opengl/lib/cmake/Qt5Gui/Qt5GuiConfigExtras.cmake:14 (message):
Failed to find "glu32" in "".

CMakeLists.txt:570 (FIND_PACKAGE)

因为很多其他人在我按照这个说明之前遇到了这个问题 ( http://qt-project.org/forums/viewthread/30006/ ):

So it worked for me(at least the CMake coniguration, didnt try to actually use it in compilation yet). Steps to reproduce:

1. I used precompiled version of Qt 5.1(the one with OpenGL x64 for VS2012). To use it should be fine for you, as Qt 5.1 should support OpenGL3.2+ profiles out of the box, i dont think you need to use Glew anymore, just look at http://qt-project.org/doc/qt->5.1/qtgui/qabstractopenglfunctions.html hierarchy
2. Installed Win SDK 8.0. But i think 7.0 could be fine.
3. added set (CMAKE_PREFIX_PATH “C:\Program Files (x86)\Windows Kits\8.0\Lib\win8\um\x64”) line to my cmake file. That’s where glu32.lib and similar files are located.
4. Run cmake-gui configure&generate, using VS 11 win64 as generator.

它尝试了两者(不是在同一个构建过程中):

set(CMAKE_PREFIX_PATH “D:\Programme\Microsoft SDKs\Windows\v7.0\Lib\x64”)
set(CMAKE_PREFIX_PATH “C:\Program Files (x86)\Windows Kits\8.0\Lib\win8\um\x64”)

我收到上面发布的错误和以下警告:

我认为这些警告不像大多数其他警告那样无害，并且表明 CMake 根本无法找到正确的目录。

有没有人知道如何解决这个问题，或者如果不是的话，有没有在 Windows7(x64) 上使用 osg 3.2.0 和 MSVS2012 为 Qt 5.1 预编译的 osgQt 版本？

最佳答案

在CMake中，\是转义字符。要将实际的 \ 添加到字符串，您需要将其转义，即使其成为 \\。

所以你需要做:

set(CMAKE_PREFIX_PATH "D:\\Programme\\Microsoft SDKs\\Windows\\v7.0\\Lib\\x64")

或者，您可以将路径分隔符更改为 /，即使对于 Windows:

set(CMAKE_PREFIX_PATH "D:/Programme/Microsoft SDKs/Windows/v7.0/Lib/x64")
