[Plib-users] The Necessity of DLL's

[Matt J. <mat...@fa...>]

Hi, I'm new to PLIB and am just looking into whether it is suitable for
my project.

The application will be on win32 (with a later view to porting across
platforms) and I expect to use either GLUT or freeglut.

Does this mean I will have to provide the glut32.dll with my project? 
Despite the possibility of statically linking with libraries like
glut32.lib it still seems all GLUT apps require this DLL too, and
ideally I want to minimise dependencies...

So maybe freeglut is better for this (ie. it may allow static linking
without using any DLL's at runtime)?  Indeed I would much prefer to use
freeglut for a variety of reasons.
Hoping this question is not misplaced: what do I need to do to build an
application with freeglut (and remove dependencies on GLUT)?  I know in
readme.GLUT it says it does not depend on glut, but without the DLL
there anything I try still gives the same 'unable to locate glut32.dll'.

Any help greatly appreciated!
Cheers,

Matt

If you utterly want to minimise depenencies and your windowing needs are
very basic (ie opening one window and rendering OpenGL into it) - then
you may be able to manage with PLIB's own 'PW' windowing library.  For
simple single window applications, it's a lot like GLUT...but it's a part
of PLIB so there are no extra dependencies.

Both GLUT and freeglut will work as either statically or dynamically linked
libraries.   I'm not a Windows user - but I think it's your choice.

Not much - freeglut is intended as a plug-compatible library - if you are
compiled and running with GLUT.DLL, you can just replace that with the
freeglut DLL and it should still work - you don't even need to recompile.

It sounds like you are still linking against it...look at your
compile commands.

if you put glut32.dll in your project folder it will still work as you
thinking about plib never used it but as i worked on glut and
glui.glui is small but interesting for menus instead of using right
mouse better to use GUI.

Yes, this seems like the crux of it!  As a relative newbie I still
haven't sorted this dynamic/static stuff out yet.

Sounds interesting, I'll look into it.  cross-platform too, I hope?
Anyway, huge thanks for all the help :)

Yes - of course!

I was thinking about your linking problems - have you tried copying
(and modifying) the MSVC project files that come with the PLIB examples
files?   Some of those use GLUT and some use PW.
