[LLVMdev] llvm-gcc cross compiling for ARM

[D S Khudia]

Here is how I do it on x86-64 machine running Ubuntu-11.04:

1. install flex and bison
2. download arm-2011.03 from www.codesourcery.com and add to path (setenv
PATH ${PATH}:/home/dskhudia/projects/arm-2011.03/bin)
3. mkdir llvm-gcc-obj; cd llvm-gcc-obj
4. ../llvm-gcc-4.2-2.9.source/configure   --target=arm-none-linux-gnueabi
--program-prefix=llvm-
--enable-llvm=/home/dskhudia/projects/llvm-2.9/obj-arm
--prefix=/home/dskhudia/projects/llvm-install-arm
--with-sysroot=/home/dskhudia/projects/arm-2011.03/arm-none-linux-gnueabi/libc
--with-gnu-ld=/home/dskhudia/projects/arm-2011.03/bin/arm-none-linux-gnueabi-ld
--with-gnu-as=/home/dskhudia/projects/arm-2011.03/bin/arm-none-linux-gnueabi-as
--with-gnu-ar=/home/dskhudia/projects/arm-2011.03/bin/arm-none-linux-gnueabi-ar
--disable-bootstrap -disable-optimized --disable-multilib --enable-checking
--disable-shared --enable-languages=c,c++

Hope that helps.
