[LLVMdev] Generatin code for an ARM-LINUX machine

[Juan Carlos Martinez Santos]

Hello Misha,

I used the snapshots for the latest stable version (70786), and I followed
the instructions inside of README file (very clear!!!)

However, when I ran the hello program, I get an unrecognized option message.
Bellow are the details.

============================================
jcmartin78 at jcmartin78-laptop:~/LLVM/my-test$ llvmc hello.c
as: unrecognized option '-meabi=4'

This is my PATH:
*****************************************
PATH=$PATH:/home/jcmartin78/local/llvm-project/x86_64-unknown-linux-gnu/arm-none-linux-gnueabi/llvm/bin:/home/jcmartin78/local/llvm-project/x86_64-unknown-linux-gnu/arm-none-linux-gnueabi/llvm-gcc-4.2/bin
*****************************************

Any idea what could be wrong?

Thanks in advance,

Juan Carlos
