Hello Marco 

Thank for infomation.
I would like to use Qt terminal on Cygwin. 
Unofficial workround exists for Qt.
Anyway I will use wxterminal instead for the moment.

The default C++ standard targeted by gcc-11 is gnu++17.

Given how old Qt5 is and that the upstream packages were compiled w/
gcc-7 mostly, I'd guess you should either add -std=gnu++11 or
-std=gnu++14 to the CXXFLAGS.

I tried both  CXXFLAGS="-std=gnu++11" and CXXFLAGS="-std=gnu++14" to the configure but the results are the same.

It turns out this is a latent bug in Qt5 sources.  It was relying on an
implicit include chain that is no longer present in gcc-11 header files.

cygport compile command fails

[Tatsuro MATSUOKA]

Hello

In order attach patch to QT tried to use the cygport.
Download qt5-base-5.9.4-2.src
and go to directory qt5-base-5.9.4-2.src

$ cygport qt5-base.cygport compile
>>> Compiling qt5-base-5.9.4-2.x86_64
/usr/share/cygport/lib/syntax.cygpart: line 156: /usr/src/qt5-base-5.9.4-2.src/qt5-base-5.9.4-2.x86_64/log/qt5-base-5.9.4-2-compile.log: No such file or directory

What is wrong?

the sequence is:

cygport qt5-base.cygport prep compile install package check

or

cygport qt5-base.cygport all check
