First, I hope I've directed this question to the correct
mailing list: I'm not sure if it's pertinent to this list
or to the cygwin list.
I frequently use cygwin-xfree to log onto external
host machines, usually Solaris or SGI-based.
This environment worked quite well for me
until recently, when I updated my Cygwin
installation. Ever since then, it appears, that none
of the openGL applications running on the host
machine have been able to access openGL in the
cygwin-xfree server. For example, here is the
error message I get from an application based on
TCL/TK scripting, which interfaces with openGL
using the togl package:
Togl: couldn't get visual while executing
"togl $dw -width $wwidth -height $wheight -rgba true -double true
-depth true -ident Box2 -overlay true"
Apparently, the TCL/TK application can't locate the openGL
facility, anywhere. Another application, the CFD visualization
software FIELDVIEW, does not work when openGL graphics
are specified specified, but works fine when X-based graphics are
Has anyone experienced anything like this recently, and/or
can they assist in finding this problem? I've attached the
cygcheck output, and I've tried re-installing the openGL
libary, with no success. I'm contemplating simply
reinstalling all of cygwin-xfree, if worse comes to worse.
Thanx in advance for any help. The cygcheck output is
