> 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,
