Speex dev - Oct 2006 - To symbian and speex developers! Building instructions

Hello to everyone!

During building speex library for Symbian OS I encountered some problems. All
thess problems can be solved by modifying the speex sources. I don't have
access to SVN repository of speex, so I will just describe the changes to be
done:

1) mmp file in symbian derictory misses windows.c sources. You need to add this
string into speex.mmp:

SOURCES windows.c

2) Symbian OS doesn't support static writable data, so you have to modify
filters.c sources file. You need to make all global definitions of shift_filt
constant. Like this:

const spx_word16_t shift_filt[3][7] = ... (just add 'const')

Also it will be excellent if somebody can make symbian readme more informative.
I think readme file should remind to symbian developer to include speex.lib as
STATICLIBRARY reference. Otherwise symbian developer will waste a lot of time
trying to find the reasons for linking problems,

Thanks,
Payu Sergey

if it works ok then it would be nice if Jean-Marc could apply it to svn.

not sure what you mean by "just add const" - could you please send a
working
patch to the mailing-list so I could test it ?

I think this mail was intended for the group.

jean, please change that one line in filters.c (I too confirm this change 
in my symbian build). the mmp file should also be updated by including the 
windows.c.

I also recommend taking out mfd.c from the mmp file as the ARM cpu is too 
slow to support echo cancellation and preprocessing that require floats.

thanks payu, for the input. i remeber fixing this but i promptly forgot 
which filter was not const.

I already fixed filters.c in svn and will apply Alfred's patch soon.

Actually mdf.c can be compiled for fixed-point.
