成功运行配置脚本（参见Building Qt 5.8 from source - configure: Unknown command line option '-c++11'）后，我开始构建：
mingw32-make.exe -j 4
但过了一段时间后我遇到了以下错误：
In file included from C:/msys64/home/asp/qt5/qtbase/src/xml/dom/qdom.cpp:55:0:
../../../include/QtXml/5.8.1/QtXml/private/qxml_p.h:1:85: fatal error: ../../../../../../../../../../../home/asp/qt5/qtbase/src/xml/sax/qxml_p.h: No such file or directory
#include "../../../../../../../../../../../home/asp/qt5/qtbase/src/xml/sax/qxml_p.h"
我搜索了该文件，它应该在哪里：
ls ~/qt5/qtbase/src/xml/sax/
qxml.cpp qxml.h qxml_p.h sax.pri
这是Qt 5.8.1的问题还是我忘了设置一些选项？我会尝试5.7，但我不希望有更好的结果。
使用5.7时，configure脚本不会显示成功消息：
Creating qmake...
...........................................................................................Done.
Info: creating stash file C:\msys64\home\asp\qt-build\.qmake.stash
Info: creating super cache file C:\msys64\home\asp\qt-build\.qmake.super
在Qt 5.8中有一条消息：
Qt is now configured for building. Just run 'make'.
Once everything is built, you must run 'make install'.
Qt will be installed into 'C:\msys64\opt\qt'
但也许这是正常的，所以我开始构建：
mingw32-make.exe -j 4

所以5.7是别无选择。
我尝试了Qt Downloads的其他版本：
所有版本都失败，因为无法找到unicode子文件夹中的某些ICU标头。但我发现了一件奇怪的事情：如果我在相应的文件夹中手动启动失败的命令，则生成的输出没有错误！然后我可以再次开始制作并再次重复此过程几个文件。但我无法以这种方式完成整个构建......
