[Vis5d-users] Re: vis5d 2 vrml

Hi,

The vis5D  is runnig!! with small changes in the Makefile:

linux-mesa:
   "CFLAGS =3D -c  -DLITTLE -DUNDERSCORE  -DOPENGL -DSINGLE_TASK=20
-DNCAR_DATA -I../Mesa/include" \
#    "CFLAGS =3D -c -O2 -w  -DLITTLE -DUNDERSCORE  -DOPENGL -DSINGLE_TASK=
=20
-DNCAR_DATA -I../Mesa/include" \


but the "save scene" option is disable

when I compiled with the -DNCAR_SCENE flag set...  I obtained:

       graphics.ogl.c: In function `save_3d_window':
       graphics.ogl.c:1397: structure has no member named `StereoOn'
       graphics.ogl.c: In function `save_3d_right_window':
       graphics.ogl.c:1404: structure has no member named `StereoOn'

and  compiling with -DNCAR_SCENE and -DNCAR_STEREO flags set, I obtained:

       main.o: In function `input_float':
       main.o(.text+0x13e5): the `gets' function is dangerous and should=20
not be used.
       api.o: In function `vis5d_save_scene':
       api.o(.text+0x1d974): undefined reference to `save_3d_scene'
       graphics.ogl.o: In function `make_big_window':
       graphics.ogl.o(.text+0x326): undefined reference to=20
`GfxStereoEnabled'
       graphics.ogl.o: In function `make_3d_window':
       graphics.ogl.o(.text+0x84b): undefined reference to=20
`GfxStereoEnabled'
       graphics.ogl.o: In function `save_3d_window_from_oglbuf':
       graphics.ogl.o(.text+0x2b94): undefined reference to `SGI_Dump'

then I changed the  display_context struct definition in the=20
src/globals.h file, in this fashion:

   int        StereoOn;        /* Actually display stereo    */
#ifdef    NCAR_STEREO
  int        StereoEnabled;        /* Stereo mode enabled        */
  /*int        StereoOn;        /* Actually display stereo    */
  int        OldGfxProjection;       /* 0 =3D parallel, 1 =3D perspective=
 */
#endif    /* NCAR_STEREO */

...and  I compiled with -DNCAR_SCENE flag set. the errors were :

       main.o: In function `input_float':
       main.o(.text+0x13e5): the `gets' function is dangerous and should=20
not be used.
       api.o: In function `vis5d_save_scene':
       api.o(.text+0x1d974): undefined reference to `save_3d_scene'
       graphics.ogl.o: In function `save_3d_window_from_oglbuf':
       graphics.ogl.o(.text+0x26a4): undefined reference to `SGI_Dump'

Is there possible to solve the  SGI_Dump non-portable issues?

Thanks,
