[xorg-server] cross compile (arm-linux) error. help~

[oxoooooooo]

Dears:


Who can tell me how to cross compile xorg-server 1.5.1 (from X11R7.4 release
version)?
My Env:  arm-linux 2.6.21 gcc-4.3.1, support framebuffer

I can successfully compile all  following items in build-from-tarballs.sh:
	build util util-macros
	build_doc
	build_proto
	build_lib
	build data xbitmaps
	build_app
but,when compiling xorg-server 1.5.1,i got errors. 

I think maybe is my configure fault, my params & error:
"--host=arm-linux --target=arm\
 --disable-composite \
 --enable-tslib \
 --enable-kdrive \
 --disable-xorg \
 --disable-xorgcfg \

 --disable-xdm-auth-1 \
 --disable-dri \
 --disable-xnest \
 --disable-xvfb \
 --disable-xprint \
 --disable-dmx \
 --disable-xephyr \
