OpenGL and GGI

[teunis]

Heya.
Is it possible to do an accelerated 2D driver under OpenGL?

Should be, I can't see why not.

Any driver to look for ideas?

It'd be cool to have an accelerated X that runs under OpenGL...
... As an answer to some of the X versus FB stuff

G'day, eh? :)

ggiResources

[Christoph Egger]

Hi all!

I have some questions regarding this functions in the ggi/ggi.h:

/* Resource functions
 */
#define ggiResourceAcquire(res, actype) \
(((res) == NULL) ? 0 : ggiResourceFastAcquire((res), (actype)))
#define ggiResourceRelease(res) \
(((res) == NULL) ? 0 : ggiResourceFastRelease((res)))
#define ggiResourceMustAcquire(res) ((res) != NULL)
int ggiResourceFastAcquire(ggi_resource_t res, uint32 actype);
int ggiResourceFastRelease(ggi_resource_t res);


There's _no_ manuals available, and I know really _nothing_ about this
functions.

I want to know:

1. What do they do?
2. Which resources are they regarding to?
3. How should they handled?

Is anyone here, who can help me?

Huh? There's a manpage complete with an example showing how to use
them with DirectBuffers.

 I want to know:
 
 1. What do they do?

User-wise; acquire and release various resources.
Implementation-wise; just about anything, check the source.

 2. Which resources are they regarding to?

Anything, but currently they are only used for DirectBuffers.

 3. How should they handled?

See the ggiResourceAcquire man-page.

  Is there a way to have it determine the correct extension, or add a

 Sure. It is already prepared in the configure.in script. The DLLEXT variable
 has to be set according to the OS detected.
 
 This can be done like this:
 
 if test "$ac_cv_header_windows_h" != "yes"; then
   DLLEXT=dll
 fi

Not really nice, I'd like to be able to have whatever headers I want
on my system without things breaking. Better to do:

case "${target}" in
  *-*-mingw* | *-*-cygwin*)
DLLEXT="dll"

I've written a GGI_DLLEXT macro which does just this, please verify
that it works correctly when compiling with mingw32/cygwin.

genkgi.so

[Cesar Crusius]

I have a question on compiling/installing. I didn't install kgi because my
chipset is not supported (chipstech 65xxx), and I didn't know how to
compile it for my hardware.

As a result, every ggi application exits with a "genkgi.so library not
found" error (the app runs ok, but the error is there). As a result, I can't
use ggi apps in the mailcap for netscape: it will get the error, pop up a
window and will not execute the application...

What should I do?

Ah... yes! Sorry, It was my fault. Because of a typo-error I made, the
man-command didn't found the ggiResourceAcquire man-page. :-(

 
  I want to know:
  
  1. What do they do?
 
 User-wise; acquire and release various resources.
 Implementation-wise; just about anything, check the source.
 
  2. Which resources are they regarding to?
 
 Anything, but currently they are only used for DirectBuffers.

Could they used for z-buffer, alpha-buffer, etc ?

If no, are there another ways to use the z-buffers, alpha-buffer, etc ?

 
  3. How should they handled?
 
 See the ggiResourceAcquire man-page.

Done. That point is now clear for me. TNX.

Right you are. I should have stressed the "can" more ... :-).
