[LLVMdev] How to Cross compile llvm to ARM ?

[李柏舉]

Hi all

        I want to cross compile llvm for arm architecture on Devkit8000.

       ARM toolchain: arm-2011.03
       LLVM: llvm-2.9
       binutils: binutils-2.21

       The following is my approach:

            1. install binutils- 2.21
                put binutils to llvm src directory
                ./configure    --target=arm-linux
                                   --prefix=/path/llvm-src/arm
                                   --disable-optimized
                                   --enable-bindings=none
                                   --disable-multilib --disable-bootstrap
                                   --with-sysroot=/path/llvm/arms/sys-root

 --with-binutils-include=/path/llvm/binutils-2.21/include
                                   --with-llvmgccdir=/path/llvm/llvm-gcc-4.2

                make
                make install

             2.install LLVM
                ../llvm-2.9/configure --target=arm-none-linux-gnueabi
                                             --host=arm-none-linux-gnueabi
                                             --prefix=/path/llvm/install
                                             --disable-optimized
                                             --enable-bindings=none
                                             --disable-multilib
                                             --disable-bootstrap

 --with-sysroot=/path/llvm/arms/sys-root

 --with-binutils-include=/path/llvm/binutils-2.21/include

 --with-llvmgccdir=/path/llvm/llvm-gcc/llvm-gcc-4.2-2.9-i686-linux
                                             CFLAGS = '-static'

               make
               make install

               done !
