Thanks Rob and Chris.
My present status is a fairly working 2.47 pdl install on Vista 32bit - I just
wish I had history capability for the shell. I dropped 5.10 wiped my perl
directories and did a fresh install of everything. Ppm is nice in that you can
take a listing of your modules that were installed in to your site\lib and then
script it for auto install on the next release. So I installed pretty much
everything using ppm - except Devel::REPL which had issues - itemized in 3).
1) OpenGL - I followed Chris's advice and found a couple of freeglut.dll that
were not of the same version. I deleted them all and I compliled the latest
freeglut using VisualStudioExpress and although it is a lot larger (752KB) than
the previous versions (~200KB), it works nicely through all of the 3d demos. I
believe I created the dynamically linked version - not the statically linked,
then again I am not a programmer so I may be wrong...
Updated - I removed my compiled freeglut.dll from the system32 directory and
then reinstalled OpenGL - works fine. If you need to use your own compiled
freeglut.dll & .lib, then one needs to download OpenGL using cpan, replace the
.dll and .lib with your versions, then complete the make and make install from
cpan. Either way works.
2) I have been using the latest version (well I actually updated to the latest
with the install on this new computer) of GrWnd for the last several releases
and it works fine on my machine. I believe that I downloaded the Prebuilt
binary for MinGW (I have it installed). Yes, the error you described about the
second window opening causing the error is the fault that I am experiencing. I
have tried to download the toolkit > 10 times now and it simply times out
before completing, so I have not tried to build my own version of the
GrWnd.dll. This doesn't impede my use that much since I only have one window
open.
3) pdl2 kind of works on my machine. I had to force install Devel::REPL from
cpan as the version in the ppm browser was too old and I thought that I saw
that it was 1.03.0111 but after the install from ppm it seemed to go back to an
earlier version. So I thought that it was installed, but it apparently failed
quietly. I went in to cpan and tried to install, but it would fail on
Sys::SigAction but said it may work if forced. Once I completed the force
install, pdl2 would launch. Once able to launch pdl2 I get the following
errors:
C:\Users\eclisob>pdl2
Unable to find PDL/pdldoc.db in C:/Perl/site/lib:C:/Perl/lib:.
And upon exit:
pdl> Use of uninitialized value $lines in substitution (s///) at C:/Perl/site/li
b/PDL/Perldl2/Plugin/PDLCommands.pm line 29.
Freeing FFT space
warning: unable to WriteHistory to C:/Users/eclisob/.perldl_hist
I was not able to use command history either - probably due to the error I am
guessing. I don't know why the error exists, I even opened up the security on
Vista to allow everyone to read/write/execute/modify the file to no avail. I am
using the Term::ReadLine::Perl module for the readline capability. The cpan
shell does have command history.
By the way, previously when Devel::REPL was not installed (properly) it did not
drop down to perldl properly. It was in some weird state where the prompt said
pdl> but the commands were DOS commands - I tried help and it listed the DOS
commands...
If you can think of any reason why the history is not working I would
appreciate any help.

Apparently, on MS Windows, we can't open a second grwnd.exe window, even if the
first instance has been closed. (This is the doing of the PGPLOT module, and
might even go back to the pgplot.dll.)
There is, however, a way of getting a second window to open. Try this
script:
##########################
use PDL::Demos::Screen;
use PDL::Demos::PGPLOT_OO_demo;
PDL::Demos::PGPLOT_OO_demo::run();
###########################
To run the pgplot demo in the cmd.exe shell (ie not in the pdl shell), run this
script:
###########################
use PDL::Demos::Screen;
use PDL::Demos::PGPLOT_demo;
PDL::Demos::PGPLOT_demo::run();
###########################
The transform demo has a couple of problems. Firstly there's 3 occurrences of a
hardcoded '/xw' that need to be replaced with '/GW' for MS Windows - I've now
fixed that in the git version of Demos/Transform_demo.pm.
Secondly, there's the problem mentioned above - that an (inevitably
unsuccessful) attempt is made to open a second grwnd instance. I haven't yet
done anything about that - the demo still goes apeshit when the attempt to open
the second window is made. (As I mentioned above, see Demos/PGPLOT_OO_demo.pm
for a method of getting 2 windows.)
I used this script to run the transform demo in the cmd.exe shell:
#############################
use PDL::Demos::Screen;
use PDL::Demos::Transform_demo;
PDL::Demos::Transform_demo::run();
#############################
And for bad2:
#############################
use PDL::Demos::Screen;
use PDL::Demos::BAD2_demo;
PDL::Demos::BAD2_demo::run();
#############################

I gave that GrWnd.exe a try, but pgplot.dll croaks with an error that it failed
to open grwnd - even though the GrWnd.exe window opens up fine.
Maybe we need to use that GrWnd.exe with the static library that ships with it.
I haven't summonsed the energy to try that static library out - looks to me
that it doesn't have any drivers other than grwnd (which dampens my enthusiasm
somewhat).
Cheers,
Rob
