I've been poking around the X source code for cygwin, trying
to figure out how the X libraries support the externing of Xt
widget class variables.
I really want to figure out how to create my own shared X library
DLL's for the Khoros library, because one of the main features
of our visual programming language depends on the ability of
using dlopen to load new widget subclasses at run time.
Anyway, I came to the realization today, that no libXt.dll or
libXmu.dll file exist in the cygwin-xfree-4_0-cygwin-v-1_tar.bz2
X11 cygwin distribution. This wasn't true in earlier X11
releases, so is this a problem that needs to be fixed? If this
was on purpose, is it because it's impossible to export the
class variables for widgets?
Also, while looking at the source code and imake rules in the
xc-*.tar files, I found the X code is using image-base in dllwrap
to provide a default address to load each library. Does this
effect how the externing of global variables (so you don't to
use that __declspec(__dllexport) and __declspec(__dllimport))
Any help is appreciated.
