qt - 使用 MSYS2/MinGW 64 从源构建 Qt 5.x - 缺少 ICU unicode header

Question

成功运行配置脚本后(参见 Building Qt 5.8 from source - configure: Unknown command line option '-c++11')我开始构建:

mingw32-make.exe -j 4

但一段时间后我得到以下错误:

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"

我搜索了这个文件，它在它应该在的地方:

ls ~/qt5/qtbase/src/xml/sax/
qxml.cpp  qxml.h  qxml_p.h  sax.pri

这是 Qt 5.8.1 的问题还是我忘记设置某些选项？我会尝试 5.7，但我不希望有更好的结果。

对于 5.7，配置脚本不显示成功消息:

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

对于 Qt 5.8 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 是别无选择的。

我尝试了来自 Qt Downloads 的其他版本:

• qt-everywhere-opensource-src-4.8.7.ta​​r.gz
• qt-everywhere-opensource-src-5.6.0.7z
• qt-everywhere-opensource-src-5.6.2.7z
• qt-everywhere-opensource-src-5.7.0.7z
• qt-everywhere-opensource-src-5.7.1.7z
• qt-everywhere-opensource-src-5.8.0.7z

所有版本均失败，因为无法找到 unicode 子文件夹中的某些 ICU header 。但是我观察到一件奇怪的事情: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!然后我可以重新开始制作，稍后再重复这个过程几个文件。但我不能那样做整个构建......
