The (very old) Insight Tcl (4) didn't need X, this one does.
tcl-tk-devel 8.5.18-1 had all those dependencies, but 8.6.6-1 and 8.6.8-1 dropped those, [possibly because the view of the target for tcl-tk-devel shifted from low level X11 development to high level tcl development, or possibly because ongoing replacement of X by EGL-based alternatives like Android and Wayland eliminate the X requirement] so the new setup does not require them, and may uninstall them on upgrade from the old release, so they would need to be reinstalled manually if you use them: setup... -P 'cygwin-devel libX11-devel libXext-devel libXft-devel libXrender-devel libXss-devel libbz2-devel libexpat-devel libfontconfig-devel libfreetype-devel libpng16-devel tcl-tk-devel'. Perhaps you should be using the Xming development package sources rather than Cygwin/X devel packages, which may not be at the same release as Xming? > (aside: I'm using XMing for all local X display stuff on Cygwin and the > Windows Linux Subsystem, so the X stuff I install under Cygwin is minimal. > Anyone else doing this?) Nope - preferred Cygwin/X as better integrated and more standard. -- Take care.
