Hi Mark,
there is still an issue compiling a QT5 program
using 5.15.18 with a simplified qscintilla2.cygport
(not QT4 and no Python) the build stops at linking phase
g++ -shared -Wl,--out-implib,libqscintilla2_qt5.dll.a -o
cygqscintilla2_qt5-13.dll qsciscintilla.o ....
.. moc_ScintillaQt.o -lpthread /usr/lib/cygQt5PrintSupport.dll /usr/
lib/cygQt5Widgets.dll /usr/lib/cygQt5Gui.dll /usr/lib/cygQt5Core.dll -lGL
/usr/lib/gcc/x86_64-pc-cygwin/13/../../../../x86_64-pc-cygwin/bin/ld:
cannot find /usr/lib/cygQt5PrintSupport.dll: No such file or directory
/usr/lib/gcc/x86_64-pc-cygwin/13/../../../../x86_64-pc-cygwin/bin/ld:
cannot find /usr/lib/cygQt5Widgets.dll: No such file or directory
/usr/lib/gcc/x86_64-pc-cygwin/13/../../../../x86_64-pc-cygwin/bin/ld:

/usr/lib/gcc/x86_64-pc-cygwin/13/../../../../x86_64-pc-cygwin/bin/ld:

with 5.9.4-x the build is without problems.
Attached scintilla2.cygport and the logs for both cases.
Thanks for the report and all the logs. "Something" is causing the link
step to look for DLLs in /usr/lib instead of /usr/bin. What's in
/usr/lib are static libraries (but their names look like libQt5*.dll.a).
I've been running into this while building the Qt5 libraries too, and
I've been working around it in src_compile() by symlinking the needed
DLLs into /usr/lib and deleting them afterwards. Ugly but effective.
If I apply that workaround to your qscintilla2.cygport, that gets past
these errors you reported. Bad news is, the compile continues and needs
Qt5Designer, which I had not yet updated to 5.15.18. I'm doing that
now. We'll see if that's enough...
Cheers,
..mark
