Building Tk for Cygwin

[Arjen Markus]

I am encountering odd problems when I try to build Tk for Cygwin. For some reason the tclStubPtr is undefined (with a number of related messages) but I also see most of the object files in the win subdirectory, while I definitely build from the unix subdirectory.

I used the following command to configure the build:

./configure --with-tcl=/usr/lib

so pretty basic.

What should I instead?

I'm using Msys and the Visual Studio compiler, but I would expect the
same to work in cygwin/gcc:

I start in the 'win' subdirectory, calling ./configure from there.
My own Makefile-windows (not the one in tk subdirectory) has:

tk: tcl
cd $(TKDIR)/win \
&& sh ./configure $(THREADS) $(DEBUG) $(PREFIX) \
&& make \
&& make install-binaries install-libraries install-private-headers

with
TKDIR = tk source tree top directory
THREADS = -disable-threads (don't ask)
DEBUG = -disable-symbols
PREFIX = .../installation-path

Works for tcl 8.5.19 and 8.6.8.

Maybe worth a try to start in 'win' instead of 'unix'.

The reason I am trying to do this is that Cygwin acts as a UNIX/Linux system - so the mousewheel events are reported as button presses 4 and 5 (using the X Server that comes with Cygwin). TIP 474 suggests to map these events to mousewheel events as under Windows and OSX. And that is what I am trying to achieve ;).

The build scripts seem to be less clear about what Cygwin actually is in terms of build environment.

Jan Nijtmans has made a speech about cygwin builds on Windows:

http://www.eurotcl.eu/presentations/EuroTcl2012-Nijtmans-Cygwin.pdf

I just find it confusing. But since that, I know to test for windows is:
file libext eq ".dll"...

Hope this helps,

Ah, thanks - building Tcl on Cygwin is not a problem, but with Tk I ran into the problems I reported.

BTW, I discovered I can also use another platform to test my changes, so the need to build on Cygwin is less pressing.
