MSYS2 unable to compile QT 5.15.2
-
Dear QT users,
I have setup an MSYS2 environment exactly like this tutorial here http://www.logikalsolutions.com/wordpress/information-technology/compiling-qt-5-14-under-msys2/.
I would like to build a static QT version that works on Windows.
However, when running the configure command exactly as described in that tutorial, I receive the following error:
.D:/msys64/home/Hamzan/Src/qtbase/qmake/main.cpp: In function ‘int installFileOrDirectory(const QString&, const QString&, bool)’: D:/msys64/home/Hamzan/Src/qtbase/qmake/main.cpp:331:15: error: ‘::symlink’ has not been declared 331 | if (::symlink(linkTarget.toLocal8Bit().constData(), target.toLocal8Bit().constData()) < 0) { | ^~~~~~~ make: *** [Makefile:258: main.o] Error 1I do not understand? Nothing comes up on Google.
-
Why do you think you need msys for this? Simply install the MinGW compiler (e.g. via the Qt online installer) and compile Qt on a plain windows command line.
-
Because compiling on windows always gives me errors.

When you would post the error message we can maybe help.

It's not an issue I dropped it and after 30+ times of recompiling QT, recompiling it on windows without the -j parameter worked.
