Thanks very much for doing these two tests (with and without Ada). I
agree these results are the best Cygwin results (outside your DISPLAY
issues where I think I have found a solution below) we have ever seen.
For example, because you are now using lua-5.2, you are getting a
clean Lua run-time result, e.g.,
lua
Missing examples :
Differing graphical output :
Missing stdout :
Differing stdout :
And you similarly have clean results for c++, f95, python, and tcl. To see all
of these
voluminous diff results for every configuration, I suggest you try
grep -B1 -A3 "Missing examples" */output_tree/*.out |less
If you run that command, you will notice that Python and Lua results are
missing for
the static case, but that is by design; those bindings only work
for the shared library case.
With regard to the on-going Ada problems, thanks to your first report
I have now tracked the issue down to an incomplete link command for
the Ada library, i.e., my CMake Ada language support is incomplete on
Cygwin. I am going to take a quick look at that now, but if it looks
like the fix is going to be complicated, I will likely put off working
on it until after this forthcoming release has been made.
I also am just in the process of revising Tcl/Tk linking to eliminate
redundant linking of libtclmatrix, libplplottcltk, and libplplot when
ENABLE_DYNDRIVERS=OFF. (For that case all the libtclmatrix and
libplplottcltk code is already in libplplot so the first two libraries should
not even be built, and all links should be made solely to libplplot
rather than those first two libraries.) I think this change is going
to sort out some memory management issues we have historically had
with interactive testing of Tcl/Tk on both Cygwin and Linux in the
past for the ENABLE_DYNDRIVERS=OFF case. We worked around those issues
by dropping such testing, but I am also going to reinstate that testing
to make sure this elimination of redundant linking cures all these
problems.
Meanwhile, so that you can start interactive testing again
you have to sort out the DISPLAY issues that are
currently prohibiting your interactive tests of Tcl and Tk. For
example, in the present results for cmake.out you have the following
error/warning set of messages:
-- TK_WISH = /bin/wish
Application initialization failed: no display name and no $DISPLAY environment
variable
Error in startup script: couldn't load file "/usr/bin/tk85.dll": No such file
or directory
while executing
"load /usr/bin/tk85.dll Tk"

-- Looking for Tk version with wish - not found
-- WARNING: setting ENABLE_tk to OFF
I did a google search for the terms
<cygwin "Application initialization failed: no display name">
and came up with
<http://stackoverflow.com/questions/9393462/cannot-launch-git-gui-using-cygwin-on-windows>
The most popular answer implies that since 2012 or so Cygwin made an
important Tcl/Tk and X change so a different procedure must be used to
get X working properly. That answer and its discussion gives the
exact details about what has to be done. I hope those instructions
work for you (and also Phil who is also having trouble getting X to
work on modern Cygwin). If those instructions work for you could you
please put them on our Wiki so all our Cygwin users can get access to
X?
