The x11 specific support in TriD is deprecated and
unsupported but I believe it still works with PDL-2.4.10.
The catch is that ongoing TriD and OpenGL development
might not continue to work with that option. Our work
going forwards is based on platform-neutral implementations.
Also, it would help me (the current TriD/OpenGL developer
if you could help debug the issue for your 64bit platform.
Cheers,

TriD to build by setting the POGL_WINDOW_TYPE

Hi again Chris,
I traced the problem to
~/perl5/x86_64-linux-thread-multi/PDL/Graphics/OpenGL/Perl/OpenGL.pm
From Googling for the error:
gdriver: window_type => 'glut' so not actually setting the rasterfont
This is not the problem. The is just an info
message printed out because you requested debugging
information be printed for TriD using $PDL::debug_trid.
I collected the log for a win32 PDL-2.4.10 and a cygwin
PDL-2.4.10 for the line3d.pl code with the uncommented
diagnostic lines using a line like this:
perl line3d.pl >line3d_log.txt 2>&1
where you would need to use -Mblib if you are trying
a new build of PDL using 'glut' windows rather than
forcing 'x11'.
For both runs, I get the same stuff as you but where
you stop having output at the end, I continue with the
following messages as the window contents are rendered:
display: transforming viewport!

This code is in GL.pm after line 918. It looks like
you make it past or to the $vp->do_perspective() call
but you'll need to step through in the debugger to
isolate where things stop. A neat trick is to add a line
$DB::single = 1;
where you want to start stepping through in the GL.pm
file. Then when you run line3d.pl under the debugger
and just run, the debugger will stop at that line and
let you single step from there.

It seems you fixed this before, but it still dosn't work on
my standard linux version.
In sub new()
sub new {
.....
....
# $window_type ||= 'x11';
# Use GLUT windows and event handling as the TriD default
$window_type ||= $PDL::Config{POGL_WINDOW_TYPE};
#$window_type ||= 'x11'; # use X11 default until glut code is ready
print "$window_type\n";

If set window type in there to 'x11', everything works. My linux
version does not like the 'glut' window type.
Maybe there could be a switch in there, like
if( $OS eq 'linux') { $window_type = 'x11'}
Thanks for looking at this again.
0m,
Joe
