[vorbis-dev] porting Ogg Vorbis to Symbian OS

[Alfred E. Heggestad]

Hi

I am in the process of porting the Ogg Vorbis libraries
and player(s) to Symbian OS (EPOC32) which runs on
Psion machines and Nokia 9210 to name some machines.
They are all using an ARM core.

I managed to successfully recompile libogg, libvorbis
and libvorbisfile with only minor modifications.
They include:

* removal of static data, which is not supported by
EPOC DLLs. All lookup tables are now 'const static'
* minor OS dependant changes (#ifdefs)

After the libraries were successfull compiled, I started
porting the ogg123 console app but gave up since it depends
on various things I dont have like libcurl and libpthreads.
So I took vorbisfile_example.c and wrote a simple player
with that. It runs on a Psion netBook but what I can hear
is not music - just some random repeated noise. I have tried
to experiment with word size (1 or 2), signed or unsigned
and endianess, but it does not make a difference. 

The compiler I use is gcc cross compiling for ARM,

[alfredh at dingo er5cpp]$ arm-pe-gcc -v
gcc driver version cygnus-2.7.2-960323 (Psion GCC tools v113 05/03/1997)
executing gcc version cygnus-2.7.2-960323

I am going to try a more recent version later.

But I am not giving up yet, I have only spent two days on
this so far. The changes in the libraries are possible
to compile for Linux and I have tested ogg123 (on Linux)
with the modified libraries which works fine.

If someone could give me a hint to e.g. some extra compiler
flags or compile switches I could use, misconfiguration etc.
I would be happy to hear from you. The base version is
1.0rc3.

thanks
