[FFmpeg-devel] Linking failure with --disable-optimizations
Tue Apr 15 04:50:24 CEST 2008
On x86_64, ffmpeg fails to compile when configured with
--disable-optimizations due to one minor issue. This was previously
reported at least once:
The problem is in cabac.h, decode_significance_8x8_x86(). This function
uses a table, last_coeff_flag_offset_8x8, via MANGLE. This table is
only defined (static) in h264.c.
Linking fails because that symbol is undefined in other translation units
which include cabac.h
This isn't a problem when compiled with optimization enabled because the
function using that table is never called except from h264.c;
optimization removes the function in other translation units.
What is preferred way to fix this?
Follow the comment above decode_significance_x86() and move these to
something under i386 which is only included from h264.c? (and is that ok
given the death-threat part of the comment :)?
Move the table into the header?
extern the table?
Or should these functions be disabled entirely with
