在Windows 7下编译Qt3D

Question

我试图通过以下指导来编译和安装Qt3D：

http://qt-project.org/wiki/Qt3D-Installation

我使用的是Windows MinGW方法，并使用Qt MinGW终端。

我第一次做这个过程时，它抱怨说缺少Perl。这似乎与教程背道而驰。所以我安装了草莓Perl。我在Windows上找不到这些构建脚本所期望的Perl风格的推荐。

当我说：

qmake qt3d.pro

它执行的速度令人怀疑。

当我说：

mingw32-make -j 3 install 

我收到这个错误：

:\qt3d>mingw32-make -j 3 install
d src/ && ( test -e Makefile || C:/Qt/5.1.1/mingw48_32/bin/qmake.exe C:/qt3d/src/src.pro -o Makefile ) && mingw32-make -f Makefile install
ingw32-make[1]: Entering directory 'c:/qt3d/src'
d threed/ && ( test -e Makefile || c:/Qt/5.1.1/mingw48_32/bin/qmake.exe C:/qt3d/src/threed/threed.pro -o Makefile ) && c:/Qt/Tools/mingw48_32/bin/mingw32-make
f Makefile install
usr/bin/sh: c:/Qt/Tools/mingw48_32/bin/mingw32-make: Invalid argument
akefile:64: recipe for target 'sub-threed-install_subtargets-ordered' failed
ingw32-make[1]: *** [sub-threed-install_subtargets-ordered] Error 126
ingw32-make[1]: Leaving directory 'c:/qt3d/src'
akefile:55: recipe for target 'sub-src-install_subtargets' failed
ingw32-make: *** [sub-src-install_subtargets] Error 2

坦白地说，我不知道该如何处理这个错误。

我可能做错什么了？

以上误差是Qt5.1产生的。

这里是一个类似的错误，我是通过完全相同的过程产生的Qt5.3。

C:\qt3d>

类似的错误。我在这里做错什么了？

Answer 1

把我的评论变成一个恰当的答案：

问:它的执行速度令人怀疑。

您希望在递归构建系统结构(如Qt3D )中递归地运行qmake。这意味着您需要将-r选项传递给qmake，如果使用QtCreator，默认情况下会传递qmake。手动运行qmake时，需要在命令行上显式显示。

另外，请注意，“旧”(当前的主) Qt3D代码库没有得到维护，因此即将发布的Qt版本可能会出现问题，尽管它得到了一些补丁，以便更好地处理Qt 5。如果您由于新的Qt版本而出现问题，您可以创建并希望发送补丁，或者只是降级您的主要Qt版本。

Answer 2

我遇到了与Qt5.3相同的问题，即在Windows7上用Qt5.2.1构建Qt3D，通过在qglpainter.cpp中的第2348行通过glReadPixels ()更改context->functions()->glReadPixels()来解决这个问题。

正是由于终端中的这个错误：

painting/qglpainter.cpp: In member function 'int QGLPainter::pickObject(int, int) const':
painting/qglpainter.cpp:2348:29: error: 'class QOpenGLFunctions' has no member named 'glReadPixels'
     context()->functions()->glReadPixels(x, y, 1, 1, GL_RGBA, GL_UNSIGNED_BYTE, data);

现在安装了Qt3D。

Answer 3

在您的计算机上安装perl之后，在编译过程中仍然有问题的每个人都可以查看qt3d文件夹的路径。里面不应该有空位。
