Yes, that's pretty much right.
As part of the way the the Win32 build of OpenGL caters for both MinGW and
Visual Studio (and also caters for various EU::MM failings),
$OpenGL::Config->{LIBS} is empty. Instead, the relevant linking information
is in $OpenGL::Config->{LDFROM}:
'LDFROM' => '$(OBJECT) -lopengl32 -lglu32 -LFreeGLUT -lfreeglut',
(though I'm not too sure about the relevance of the '-LFreeGLUT' bit after
OpenGL has been built).
In the OpenGLQ/Makefile.PL we can do, eg, either:
${$hash{LIBS}}[0] .= ' -lopengl32 -lglu32' if $^O eq 'MSWin32'; # Is
portable ?
or
$hash{LDFROM} .= ' '. $OpenGL::Config->{LDFROM} if $^O eq 'MSWin32';
Both get around the problem, and OpenGLQ and POGL then build fine.
Prior to building PDL, I had moved the freeglut import library and headers
from the OpenGL-0.58_005 source to a location where they would be found by
default. (I expect this is a necessary step, but I haven't checked.)
The t/opengl.t tests fail with:
t/opengl.t .................. 1/4 Your vendor has not defined OpenGL macro
StructureNotifyMask, used at
C:\temp\temp\pdl\blib\lib/PDL/Graphics/OpenGL/Perl/OpenGL.pm line 154.
I guess this is expected.
Apart from the test failure, it's all looking good :-)
Cheers,
Rob
