[Pkg-directfb-devel] Bug#480933: directfb: long term mass bug filing for cross build support

[Neil Williams]

Package: directfb
Version: 1.0.1-8
Severity: wishlist
Tags: patch
User: codehelp at debian.org
Usertags: crossbuilt

In line with the other cross-building support bugs:
http://lists.debian.org/debian-devel/2007/11/msg00116.html

This patch is necessary to allow directfb to cross-build in Debian.

The added LD variable prevents a build error at the very end of the
build:

(cd .libs/libdirectfb_fbdev.a.tmp && arm-linux-gnu-ar x
../../.libs/libdirectfb_fbdev.a)
ld -o libdirectfb_fbdev.o -r .libs/libdirectfb_fbdev.a.tmp/*.o
ld: .libs/libdirectfb_fbdev.a.tmp/agp.o: Relocations in generic ELF (EM:
40)
.libs/libdirectfb_fbdev.a.tmp/agp.o: could not read symbols: File in
wrong format
make[4]: *** [libdirectfb_fbdev.o] Error 1

I've tested this patch for Emdebian and in a normal Debian build without
problems (CROSS is empty if not cross building).
