GTK 3D implementation discussion

shash:
Good to see Mario is working for you. I did not spy the matrix * vertex function in the matrix.c code otherwise I would have used it.

snkmad and evilynux:
There maybe a slight problem with the gtk-glade port on non X Window platforms (it builds and runs 3D fine for me on Linux).
The gtk-glade code uses the HAVE_LIBGDKGLEXT_X11_1_0 macro to conditionally include 3D stuff. If you are using autotools (autoconf, automake, ./autogen.sh and ./configure) then this will only get defined on systems with X Window (Linux, BSDs and OSX?) since it is a check against the X Window target version of the gtkGLext library. There is now a macro, GTKGLEXT_AVAILABLE, which should be defined on all platforms with the gtkGLext library installed (assuming pkg-config is configured and working).

If you are building under Dev-Cpp/Visual C++ or similar then make sure that you define HAVE_LIBGDKGLEXT_X11_1_0 and GTKGLEXT_AVAILABLE as part of the C preprocessor arguments.

That sounds right... perhaps all HAVE_LIBGDKGLEXT_X11_1_0 should be renamed to GTKGLEXT_AVAILABLE ...
Damdoum did most of the MS Windows work/testing... it'd be nice if this could be sorted out.

Ok i added GLU32.dll and the glu errors are gone.
Now only these 2 to fix:
obj/main.o(.text+0x9ce):main.c: undefined reference to `init_opengl_gdk_3Demu'
obj/main.o(.data+0x4):main.c: undefined reference to `gpu3D_opengl_collector'

Note: im only trying to compile gtk glade on windows, because damdum asked if someone could help him test the win port.

Your help is appreciated.
Are opengl_collector_3Demu.h and opengl_collector_3Demu.c included?

You have to undergo some changes to take into account OSX. Headers on osx for open gl are in OpenGL/ not in GL/... There is also an issue with the fact that on Mac os x, we can't set GDK_GL_MODE_ALPHA as it is run under X11, disabling it make it runs well.

If you want me to commit some mac os x compliancy to the cvs, you can add me on sourceforge (deufeufeu).

The best would be to use "defines" so we can remain multi-platform/os. Can we easily detect that we're running on MacOSX, does gcc define a variable?

I welcome patches.

Thanks for testing!

gtk-glade/main.c includes gdk_3Demu.h and gdk_3Demu.h includes opengl_collector_3Demu.h...
so i don't know what else to suggest...

snkmad · 2007-04-23 11:51:47

Can someone post here a list of all necessary files needed to be into the project?

evilynux · 2007-04-23 12:20:07

Based on Makefile.am:
globals.h glade-xml.c \
callbacks.c callbacks.h callbacks_IO.c callbacks_IO.h desmume.c desmume.h \
keyval_names.c main.c printscreen.c gdk_gl.c gdk_gl.h \
dTools/callbacks_1_ioregs.c dTools/callbacks_2_memview.c \
dTools/callbacks_3_palview.c dTools/callbacks_4_tileview.c \
dTools/callbacks_dtools.h \
dTools/dTools_display.h \
gdk_3Demu.c gdk_3Demu.h \
../sndsdl.h ../sndsdl.c ../ctrlssdl.h ../ctrlssdl.c

Then, looking at the dev-cpp file it seems you also need to add all other used files.
Basically, everything else in src/ .

snkmad · 2007-04-23 12:32:41

Well that doesnt help, i have all files from gtk glade, and src folder into the project. It must be something else.
Sorry i cant help with this one.

same error here

masscat · 2007-04-23 13:28:15

The contents of opengl_collector_3Demu.c will only be compiled is the preprocessor macros HAVE_GL_GL_H and HAVE_GL_GLU_H are defined. Similarly to the HAVE_LIBGDKGLEXT_X11_1_0 and GTKGLEXT_AVAILABLE macros, you should define these as part of the build parameters. If they are defined then during the compile something like -DHAVE_GL_GL_H=1 will be present.

As a test, you could edit opengl_collector_3Demu.c, gdk_3Demu.c and main.c (maybe others) and define the macros (e.g. #define HAVE_GL_GL_H 1) before the first #ifdef test. This way you will know that the code is being included and compiled and if the problem persists then it is a linker problem.

deufeufeu:
I was under the impression that GDK_GL_MODE_ALPHA was needed to include a alpha channel for the off-screen render target but this does not appear to be the case (works fine without it under Linux for me). Could you post a patch for the other OSX changes on the SourceForge page?

snkmad · 2007-04-23 14:32:04

Nice tip masscat.
Ill try to do it, but dont expect much w/out help, i can only code some a + b = c operations
Im not familiar with the #ifdef...

masscat · 2007-04-23 14:44:45

At the start of the files gtk-glade/main.c, gtk-glade/gdk_3Demu.c and opengl_collector_3Demu.c put the following:

#define HAVE_GL_GL_H 1
#define HAVE_GL_GLU_H 1
#define HAVE_LIBGDKGLEXT_X11_1_0 1
#define GTKGLEXT_AVAILABLE 1

snkmad · 2007-04-23 14:51:54

Ok do i need to add
-DHAVE_GL_GL_H=1
-DHAVE_GL_GLU_H=1
to parameters?

EDIT: After doing what you said i now get the following errors:
../opengl_collector_3Demu.c: In function `SetupTexture':
../opengl_collector_3Demu.c:732: error: `GL_MIRRORED_REPEAT' undeclared (first use in this function)
../opengl_collector_3Demu.c:732: error: (Each undeclared identifier is reported only once
../opengl_collector_3Demu.c:732: error: for each function it appears in.)
../opengl_collector_3Demu.c: In function `get_line_3Dgl_collect':

gcc.exe: unrecognized option `-rdynamic'
make.exe: *** [obj/opengl_collector_3Demu.o] Error 1

Maybe i need another opengl lib where GL_MIRRORED_REPEAT and GL_BGRA are defined?

masscat · 2007-04-23 15:48:13

Just had a look on a Windows machine:

GL_BGRA maybe defined in glext.h and GL_MIRRORED_REPEAT maybe called GL_MIRRORED_REPEAT_ARB.
So change the following in opengl_collector_3Demu.c:

#include <GL/gl.h>
#include <GL/glu.h>

to:

#include <GL/gl.h>
#include <GL/glext.h>
#include <GL/glu.h>

#ifndef GL_MIRRORED_REPEAT
#define GL_MIRRORED_REPEAT GL_MIRRORED_REPEAT_ARB
#endif

Anybody know a good way to make the code portable across platforms (see also the OSX problem posted earlier)?

snkmad · 2007-04-23 16:55:03

Finally it compiles!
Thx guys, this one was hard to get working.

EDIT: Well i just had time now to take a closer look. The compiler gives some errors, but it does compile:

Warning: resolving _gluErrorString by linking to _gluErrorString@4
Use --enable-stdcall-fixup to disable these warnings
Use --disable-stdcall-fixup to disable these fixups
Warning: resolving _WinMain@16 by linking to _WinMain
Execution terminated

But as i tried Mario 64, its like all 3d core/code isnt included.

I followed all the tips here, and also i had to include GLU32.LIB.

EDi2: Heres the reason:

Thx to cyborg_

snkmad · 2007-04-24 14:02:25

Can you help me with this last problem?

masscat · 2007-04-24 16:02:33

Try the follow edit of gdk_3Demu.c (about line 160):

change:

glconfig = gdk_gl_config_new_by_mode (GDK_GL_MODE_RGBA   |
                                        GDK_GL_MODE_ALPHA  |
                                        GDK_GL_MODE_DEPTH  |
                                        GDK_GL_MODE_SINGLE);

to

glconfig = gdk_gl_config_new_by_mode (GDK_GL_MODE_RGBA   |
                                        GDK_GL_MODE_DEPTH  |
                                        GDK_GL_MODE_SINGLE);

The GDK_GL_MODE_ALPHA flag is not necessary and also causes problems under OSX.

EDIT: Removed the GDK_GL_MODE_ALPHA flag from gtk and gtk-glade gdk_3Demu.c files in CVS.

Hum still same error.

(DeSmuME-glade-24-04.exe:2840): GdkGLExt-WARNING **: cannot create GdkGLPixmap

snkmad · 2007-04-26 11:50:13

Well shash said it wouldnt be hard to fix that.
Why its not being able to set the pixel format?
Maybe the opengl has to be initialized in a diferent way for windows?

shash · 2007-04-26 12:05:51

I said I THINK it should be hard as long as it's only related to the pixelformat selection failing.

snkmad · 2007-04-26 12:35:39

Well thats the problem right now.
Maybe its the only one, maybe others will arise if you guys fix it...

If you have autotools / gcc toolchain then those are setup when you ./configure
if you use something like devcpp ... then that would be in the compiler options window ( pass -Ddefines to the compiler )
I would not know how to do it in other dev. environment but you get the idea. Those defines being in the headers are
*hackish* so I would not recommend it.

Good job :-)
I can't help right now, sorry, i dont have a computer outside work (i.e. abroad in internship)
