So I thought that it woöuld be good to update Qt5 before it becomes Qt6… unfortunately the version in Cygwin is 5.9.4 while 5.15.2 is current, so there is quite a bit of changes to wade through. It doesn't help that that the Cygwin patches never got upstreamed or accepted (the net result is the same). I think I've got the whole thing cleaned up so that it should work, but there is one change that stumps me: In 5.9.4 the QT5 libraries were linked via -L/mnt/share/packages/qt5-base-5.9.4-2.src/qt5-base.x86_64/build/lib -lQt5Core while in 5.15.2 that has changed to /mnt/share/packages/qt5-base/qt5-base.x86_64/build/lib/cygQt5Core.dll
what is curious is that it is not what you would expect by the name $ file *Qt5Core* cygQt5Core.dll: current ar archive cygQt5Core.la: libtool library file, ASCII text cygQt5Core-5.dll: PE32+ executable (DLL) (console) x86-64, for MS Windows libQt5Core.dll.a: current ar archive libQt5Core.prl: ASCII text, with very long lines $ md5sum *Qt5Core* cc96f43516bb8dfb2777119304d70cfc *cygQt5Core.dll a6a615ba27c7615d1c0414e434e9df2f *cygQt5Core.la ab6831713192ecffae52b600e4243675 *cygQt5Core-5.dll cc96f43516bb8dfb2777119304d70cfc *libQt5Core.dll.a 3cb42dafcdb46d3b9b68295064b758d5 *libQt5Core.prl and it is more or less the same for all the libs $ md5sum *Qt5Xml* 59aea92b768462b4bce6faf737152ff4 *cygQt5Xml.dll c1ad01e05508c0955cb142fc5348ea6f *cygQt5Xml.la d4db308fad54659e89baec12a1fb74e8 *cygQt5Xml-5.dll 59aea92b768462b4bce6faf737152ff4 *libQt5Xml.dll.a 2314a2fda6f78bee8d09ed4587968dc0 *libQt5Xml.prl
This nixes the fixup that was supposed to get the correct name there (which I had to disable anyway because it now mucks up the target name for the .prl stuff). I have no good idea where to fix that up, I think I'd want the link library (.dll.a) there if I need to keep the absolute path. For now I've done a monkey patch around that with a hardlink, but there must be a better way of doing it… The compile now goes through, I later get an error because it tries to use some tools that I haven't yet installed. Regards, Achim.
it crashes for me for some resource issues, but after re-kicking the build it is now running through all the examples
