[MPlayer-users] loader/ldt_keeper.c assumes Linux/x86

[Michael G Schwern]

Hello again.  While building MPlayer, both 0.90b5 and the 20020717 snapshot
on Debian/PowerPC, they both fall over in loader/ldt_keeper.c.

There's two problems here.  One is that asm/ldt.h is only in the i386 Linux
kernel headers.  It's not available for PowerPC, and I'm not sure what it is
(AMD's Lightning Data Transfer bus?)  ldt_loader.c assumes that if
__linux__ is defined, you have asm/ldt.h.

    #ifdef __linux__
    #include <asm/unistd.h>
    #include <asm/ldt.h>
    #else

So I tried changing all the "#ifdef __linux__" to "#if 0" and take the
defaults.  Unfortunately, there is x86 assembly code in ldt_keeper.c and
that just isn't going to fly on PowerPC.
