Re: [SoX-users] Large file support not working

[Chris B. <ch...@cn...>]

I'm kinda at a dead end on how to help fix the Slackware 11 fseeko() 
problems.

I can only tell this much... SoX is detecting that you have an fseeko() 
that can be linked into the program.  It is also then correctly defining 
_FILE_OFFSET_BITS to 64 to get large file support.

I see during your compiles that fseeko is not showing up in stdio.h like 
it should.  Therefore the _FILE_OFFSET_BITS variable is being ignored 
and so libc is probably running in 32 bit mode and confused why a 64bit 
fseeko() is being invoked.

sox.c:752: warning: implicit declaration of function `fseeko'

The header files being included on your system do not seem to match up 
with your libc.  Probably some issue with kernel header files (I don't 
know how slackware distributes that stuff).

Unfortunetly, I can't find a way to force autoconf to require finding a 
symbol *and* requiring its prototype to be found in a header file... If 
someone knows how to do that then we can add that check into SoX's 
configure and disable big file support when these header file problems 
are detected.
