glut message loop

[zhwang]

Hello everyone,
I am using now GLUT for window rendering on OS windows (32 bits) based
on "int main()", and it's easy to use GLUT for some simple message (for
example, keyboard, mouse, etc):
  ---glutmainloop(), and
  ---some registered function.

However, I would integrate a 3D mouse library into my existing programme.
I want to keep the existing code structure, "int main(int argc, char**
argv)",  and also to make it possible receive message defined in 3D
mouse library.

I have searched in google, but I did not find useful infos excepting the
idea of "hacking glutMainLoop()". After I tried it, I failed.

Is there anyone who works on this aspect ?

I really appreciate it for some clues.

Thank you all!

Gentlemen,

        I would like to start trying again for a new release of
"freeglut".  The first step is, are there any issues
outstanding?  From the e-mail traffic there appear to be
several.  Can we get them out of the way?  When I am able to devote
some serious energy to this I will start helping again.  Let's hope
nobody dies on me this time.

                - John

I have a few minor issues
1) In src/freeglut_cursor.c we find the line:
#if _MSC_VER <= 1200

For mingw64 builds to succeed, that needs to be changed to:
#if !defined(__MINGW64__) && _MSC_VER <= 1200

For mingw32 and MS compilers that are <= 1200, my revised rendition
evaluates as true (as it does with the original rendition) - and that seems
to be right.
For both mingw64 and MS compilers that are > 1200 it needs to evaluate as
false ... which it does.

2) With a './configure disable-static --enable-shared' build (using mingw in
the msys shell) the make process insists on locating and verifying
libopengl32.dll, libgdi32.dll and libwinmm.dll, which it can't do because
the filenames don't have the 'lib' prefix. Hence we always get a static
build. Haven't yet investigated a fix for this (other than to create copies
of opengl32.dll, gdi32.dll and winmm.dll with the 'lib' prefix in their
filename).

3) With a './configure disable-shared --enable-static' build we also have to
additionally specify CFLAGS=-DFREEGLUT_STATIC. That's ok, but I'm wondering
if the '--enable-static' should automatically define FREEGLUT_STATIC for us.
(Haven't looked at how this might be achieved. I note that '--enable-shared'
automatically defines FREEGLUT_EXPORTS for us.)

Do you require bug reports for any/all of the above ?

Cheers,
Rob

Rob,

         Many thanks for your inputs.  I don't need bug reports, but
changes to the source or configuration files would be very
welcome.  I don't pretend to be a Linux guru and I don't have a lot
of spare time these days.  I've implemented the fix to
"freeglut_cursor.c" and put that into SVN.

                 - John
