Tk::Zinc on cygwin

tevlin has asked for the wisdom of the Perl Monks concerning the following question:

Hi

  I have problems getting Tk::Zinc installed on my cygwin perl install
+ation.

  Via cygwin-setup, I have installed:
  - Perl 5.10.0-5
  - perl-Tk 804.028-1
  - opengl 1.1.0-10
  - libGL-devel, libGL1, libGLU-devel, libGLU1 7.2-2
  - libX11-devel, libX11_6 1.1.5-2
  - libXext-devel, libXext6 1.0.4-1
  - xinit 1.1.1-2
  - xorg-server 1.5.3-8
  
  
  I couldn't find a zinc package, so tried to manually install the win
+ (msi) package
  from tkzinc.org.
  As expected I got "cannot load dll file"
  
  nm zinc.dll | grep ' T _' | sed 's/.* T _//' >> zinc.def
  returns 'No symbols in zinc.dll'

  So, I downloaded http://www.tkzinc.org/Packages/zinc-tk_3.3.4.tar.gz
  After some trial and error, finally compiled and linked using -DATC 
+only (not -DGL)
  Don't know why - thought I had installed all relevant open GL librar
+ies (not opengl32.dll)
  
  Then the fun starts:
  perl demos/zinc-demos
  
  I get lots of
  - "Use of uninitialized value $id in delete at /usr/lib/perl5/vendor
+_perl/5.10/i686-cygwin/Tk/After.pm line 87."
  - "Use of uninitialized value $id in hash element at /usr/lib/perl5/
+vendor_perl/5.10/i686-cygwin/Tk/After.pm line 39."
  
  Most examples seem to work, but don't look very good (I assume missi
+ng openGL)
  
  Then I tried a program which works on (solaris & activeState)
  But I get:
 Tk::Error: Can't set -height to `undef' for Tk::Frame=HASH(0x107f3a60
+): bad screen distance "" at /usr/lib/perl5/vendor_perl/5.10/i686-cyg

  Firstly, I would like to get Tk::Zinc working with OpenGL
  Has anyone managed this on cygwin?
  
Any help appreciated.
Thanks

I don't know much about cygwin, but I'm not surprised you encounter a problem.... cygwin is already another layer of hacking complexity, ontop of win32..... apparently the dll you got has no compatible symbols to the win32 system you are using. Zinc has a win32 port on their website, that runs,(but I think they have minimum win32 level.... but I did get it to work on Win98 once ;-) In other words...trying to get a fully functional bug-free zinc, by compiling under cygwin....is probably futile. In fact, under cygwin, I believe you would try to install the linux zinc version......what a nightmare that would be...on win32 The best place to ask this the Zinc maillist.... but don't expect to get help on any Zinc version on win32, except for their approved win32 binary download.

I finally got things work fairly ok: I edited Makefile.PL with: my %DEF_FLAGS = ('GL' => 0, 'SHAPE' => 1, 'GL_DAMAGE' => 1, 'ATC' => 1 ); ie using GL_DAMAGE instead of GL Then: make clean perl Makefile.PL make make install rebaseall perl demos/zinc-demos I still get "Use of uninitialized value" errors but this seems to be a "common" Tk issue. Most of the remaining issues are X-Server related eg "GLX not available..." runtime warnings I still have 1 annoying issue: The following works: my $zinc = $mw->Zinc(-width => 500, -height => 500)->pack(); The following doesn't work: my $zinc = $mw->Scrolled("Zinc", -width => 500, -height => 500, -scrollbars => 'oe')->pack(); I get: GLX not available (need at least a 24 bits buffer with stencil) Use of uninitialized value $id in delete at /usr/lib/perl5/vendor_perl/5.10/i686-cygwin/Tk/After.pm line 87 (#1) Tk::Error: Can't set -height to `undef' for Tk::Frame=HASH(0x1ed4da8): bad screen distance "" at /usr/lib/perl5/vendor_perl/5.10/i686-cygwin/Tk/Configure.pm line 46. at /usr/lib/perl5/vendor_perl/5.10/i686-cygwin/Tk/Derived.pm line 294 Tk callback for .
