[Bug-gnubg] Compile errors and problems with board3d on Mac OS X

[Olivier Baur]

Here are some errors/problems I've met building/using gnubg 
--with-board3d (in CVS main branch)


(1) malloc.h problem:

mylist.c:24: header file 'malloc.h' not found

I've put #if HAVE_MALLOC_H / #endif around (my malloc() is in stdlib.h)
[change not commited yet]


(2) Texture problems:

At gnubg startup, I get the following error message:
Error: Texture file (textures.txt) not found

In the source code (misc3d.c:279), it seems that gnubg looks for this 
file in the $HOME directory -- is this the desired behavior?

So I copied the textures.txt to my home directory, and got rid of the 
error message.

Later on, when gnubg tried to load some textures, I got messages like:
Failed to open texture: textures//board3.bmp
(note the double-slash)

I've changed the TEXTURE_PATH to "textures/" (instead of "textures//") 
in board3d/inc3d.h, and now I get the following messages:
Failed to load texture: textures/base3.png
Failed to load texture: textures/board3.bmp

When I trace the probem back, I get down to functions LoadPNGTexture 
and LoadDIBTexture (in texture3d.c); I'm having a look at the problem 
now.

BTW, which libpng should I be using/compiling with?
My ./configure prints the following:
checking for png_create_info_struct in -lpng... no
and HAVE_LIBPNG is #undefined in my config.h


(3) Animation

Animation seems to make gnubg freeze (whether it's chequer movement or 
dice rolling). I'll have a look at it too.


(4) Image quirks

Color has come back -- I just needed to set them up in the Appearance 
settings :-)

But I still have these "lines" that strech from the chequers and the 
cube towards the lower-right corner of the board (as can be seen in the 
picture I joined in my previous post).
And when I'm dragging a chequer around, it's a whole black strip that 
stretches from the chequer towards the lower-right corner of the board, 
masking what lies under its level, and at some point plunging through 
the board and reappearing further on.
And when I turn the "Round board egdes" option on, some little white 
dotes appear at some places on the board frame.
I've included a picture of me dragging a checker about my 5-point 
(small size here on the list, I can provide more detailled screenshots 
if needed):

Also, in the Appearance settings window, the preview of the 3d board is 
just colorful psychedelic pixel crap :-)


(5) 3D color previews

3D color previews (both in the Appearance tabs and in the "3D Color 
selection" dialogs) are totally black.
