llvm dev - Jan 2010 - [LLVMdev] LLVM-gcc for ARM

OK, thank you.

Are there some pre-built X86 binaries for LLVM-gcc for ARM? It yes, where can I
download from?

Thank you,
Corina

This is provided by libc. Do you have an ARM libc? You should
configure llvm-gcc with --with-sysroot pointing to the libc install
directory. If you are building from scratch, you have to

*) Build binutils
*) Build llvm-gcc
*) Use that to build a libc (newlib, glibc,  etc)
*) Build a new llvm-gcc that can use that libc

Hello,

I recompiled binutils, llvm-gcc, libc, and again llvm-gcc and now it gives me
the following error:

llvm-gcc --v
Using built-in specs.
Target: arm-elf
Configured with:

......./ (reconfigured) ../llvm-gcc4.2-2.6.source/configure --target=arm-elf
--enable-llvm=/home/LLVM/llvm-2.6/ --with-arch=armv7-a --enable-languages=c
--prefix=/home/LLVM/install --enable-multilib --with-newlib --without-headers
--disable-shared --with-gnu-as --with-gnu-ld --program-prefix=llvm-
--disable-libssp --with-sysroot=/home/LLVM/build/arm-elf/newlib/

llvm-gcc HelloWorld.c 
/home/LLVM/install/lib/gcc/arm-elf/4.2.1/../../../../arm-elf/bin/ld: this linker
was not configured to use sysroots
collect2: ld returned 1 exit status

I would appreciate some help from you.

You have to pass --with-sysroot when building binutils too.
