GStreamer ARM cross compilation

Fri May 17 09:33:35 PDT 2013

Hi Deepak,

Thats what we pass

$ ./configure \
	--build=x86_64-unknown-linux-gnu \
	--host=armv7l-unknown-linux-gnueabihf \
	--prefix=/usr \
	--with-sysroot=/home/build/rootfs/sysroot \
	CPPFLAGS=--sysroot /home/build/rootfs/sysroot \
	CFLAGS=--sysroot /home/build/rootfs/sysroot \
	LDFLAGS=--sysroot /home/build/rootfs/sysroot \
	ac_cv_func_register_printf_specifier=no \
	ac_cv_func_register_printf_function=no

But in general I would suggest to use a cross build system such as 
buildroot [1] or yocto [2]. Accept you just do it for fun and learning.

[1] http://buildroot.uclibc.org/
[2] https://www.yoctoproject.org/
