The x86 directory contains gcc-style inline assembly for several of
the more time-critical functions. The x86_vc folder contains a similar
set of function implementations in MSVC inline assembly syntax. To
compile under VC6, you'll want to include the files in the x86_vc
directory, but not the ones in the x86 directory.
The code should work without either, using pure-C implementations of
the same functions, but will of course be slower. You also need to
define the OC_X86_ASM preprocessor symbol (macro) for libtheora to use
the assembly functions.
I believe that's the only extra define you might need to use. The
VS2008 project files also define WIN32, _CRT_SECURE_NO_DEPRECATE and
_CRT_NONSTDC_NO_DEPRECATE, but I don't think those are necessary on
Hope that's enough to get you compiling. Thanks for your interest in Theora.
