[Bug-gnubg] Mac Builds and Sound on OS/X 10.6+ w/64Bit

[Michael Petch]

Howdy All,

While I was looking into other issues last night I decided to finally 
finish install Snow Leopard on my Mac. This is the first time I have had 
a chance in a year and a half to spend time on this platform.

-----------
Sound
-----------

A couple weeks ago I spent some time (without having Snow Leopard 
installed) trying to help people on the list try to build a 64 Bit 
variant of GNUBG on this platform. The fix effectively disabled 
QuickTime sound on the 64 Bit build. I didn't eliminate the sound code, 
just didn't compile QuickTime code in.

After doing a MacPorts based build (I ran into a few bumps outlined 
below) and ran GNUBG I discovered that one can still specify an external 
application to play sounds with. This feature can be set via the 
"Settings" menu / "Options" / "Sound" tab and "Sound command". The sound 
command is the full path and name to a program that can play a sound by 
specifying a single argument (the argument is the name of the file).

I originally tries canberra's canberra-gtk-play, and for some reason 
canberra sound on my Mac environment makes the player run out of memory 
when attempting to play anything. I decided to build a program from the 
Apple examples called PlayFile.cpp available here 
http://developer.apple.com/library/mac/#samplecode/PlayFile/Introduction/Intro.html 
.

I simply modified the sample code by commenting out the printf's that 
produce console output while playing the file (This keeps it from 
appearing in the GNUBG console). The resulting binary can be downloaded 
and extracted from my site: www.capp-sysware.com/downloads/PlayFile.tar .

Extract the tar file into a bin directory ( /opt/local/bin or /opt/bin 
etc ) . This archive only contains PlayFile . Now in GnuBG specify the 
full path (and file name) to PlayFile . Exit GnuBG and reload. In theory 
you should hear sound now.

Has anyone had any success with libcanberra on their systems? I tried to 
build 64-Bit GNUBG with canberra support, it compiles but sound doesn't 
work (Yes GTK_MODULES is set correctly, and an X session display is 
set). Even the supplied program canberra-gtk-play doesn't work properly. 
I haven't gone back and tried a 32 bit version yet. if canberra would 
work consistently on this platform we could consider removing Apple 
specific sound systems.

I will be looking at integrating PlayFile's code into GnuBG. The main 
issue is that PlayFile is an Apple Open License and also relies on a 
number of .cpp classes and headers (part of the Apple SDK) with the same 
license. It doesn't seem the license is entirely compatible with GPL so 
I'll attempt to rewrite an equivalent in C and have no reliance on Apple 
headers and class files. (.h AND .cpp).

For the moment the external player method may allow people to have 64bit 
GNUBG with sound.

Mac Ports Build
-----------------------

If people are using macPorts and find that changing languages doesn't 
seem to be anything but English - I had noticed that libintl.h was not 
being found during the ./configure process (I didn't investigate the 
reason fully but appears to be pkg-config related). My MacPorts build 
process is:

Pull file's from CVS
./autogen.sh
CPPFLAGS="-I/opt/local/include" ./configure --enable-threads --prefix=/opt
make
sudo make install

---------------
Autgen.sh
---------------

While I was at it, I put away a new autogen.sh to utilize glibtoolize 
instead of libtoolize *IF* building on the Apple(Darwin) platforms. This 
naming difference has been around for all the years I have been building 
GNUBG on OS/X through all variants of OS/X .
