[LLVMdev] LLVM for ARM target

[akramul azim]

Hi,
    I am planning to follow the steps to install LLVM for the ARM-target (Processor: Xscale, Architecture: armv5te):
 
1. Install binutils-2.21 (downloaded from gnu.org)
 
Steps: 
 
$ ./configure --target=arm-unknown-linux-gnueabi --program-prefix=arm- --prefix
=/llvm/arm --with-sysroot=/llvm/arms/sys-root
 
$ make
 
$ make install
 

2. Install LLVM
 
Steps
 
$ ../llvm-src/configure --target=arm-linux --prefix=/llvm/arm --disable-optimiz
ed --enable-bindings=none --disable-multilib --disable-bootstrap --with-sysroot
=/llvm/arms/sys-root --with-binutils-include=/llvm/binutils-2.21/include --with
-llvmgccdir=/llvm/llvm-gcc-4.2
 
$ make
 
$ make install
 
3. Install LLVM-GCC
 
Steps:
 
$ ../llvm-gcc/configure --target=arm-linux --program-prefix=arm- --prefix=$PWD/
../install --disable-optimized --enable-bindings=none --enable-llvm=$PWD/../llv
m-2.8 --enable-languages=c,c++ --disable-multilib --disable-bootstrap

$ make
 
$ make install
 
 
However, when I try to build LLVM source (second step) by make, I get the following error:

Can anyone please tell me is there any problem on my plan to build LLVM for the ARM target (for armv5te) and why I get the errors when building LLVM (make)?
 
 
Thanks,

You don't have cross ARM binutils installed.
