Re: [libdv-dev] Re: libdv for AMD64

[Dean K. <kol...@qw...>]

I can't reproduce the linking problem. dv_peek_vlc is an inlined function 
in vlc.h, so it should be compiled into each .o that calls it, and not need 
to be linked. Something must be preventing the compiler from inlining 
dv_peek_vlc into dovlc.o, but I don't see how that can happen. I don't 
think it's related to the x86-64 code.

I double-checked that I can download libdv-0.104.tar.gz, apply 
libdv_reloc_fixes.tar.bz2, and do the build.

I fixed the assembler warnings in vlc_x86_64.S late last night, but that's 
just cosmetic.
