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

We have had a script for a while that does this for you in http://llvm.org/svn/llvm-project/llvm/trunk/utils/crosstool/ARM/ . It also uses the CodeSourcery toolchain so it saves you some effort.

Hello Corina, I used a two-stage sequence to build the llvm and llvm-gcc with the codesourcery toolchain and my custom built arm toolchain. There is some scripted chunks for each step. I have attached them as a single file to this email. May be it will help you somehow.

Dear Anton, Thanks for your help! I had a look to llvm (2.6) configure options but I couldn't find any way to specify cpu type, fpu ecc..Could you please give me any indication and/or example?

Hello, Pazzo > I had a look to llvm (2.6) configure options but I couldn't find any > way to specify cpu type, fpu ecc.. These are not llvm configure options, but gcc's one. Basically, you should configure llvm-gcc in the same way you do for gcc for your platform. > Could you please give me any > indication and/or example? I want to try llvm with Atmel's > AT91SAM7X256

OK, I put in my classpath the binaries from this package arm-2005q3-1-arm-none-linux-gnueabi-i686-pc-linux-gnu futrhermore in the configure options I specified --with-gnu-ld and  --with-gnu-as but I am getting the same error. exec: 2: -meabi=4: not found Any ideas? --- On Sat, 1/16/10, corina s <corina_fff at yahoo.com> wrote: From: corina s <corina_fff at yahoo.com> Subject:

Hello > exec: 2: -meabi=4: not found > make[4]: *** [crtbegin.o] Error 1 It seems you don't have cross-binutils for arm-eabi installed. Note that ARM binutils are known to be buggy - you should use the fresh CVS snapshot. PS: Please use "Reply All" button - this way the copy will be sent to llvm-dev ML and others will be able to comment / use the information as well. --

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 *)

hi, So... I followed the following steps in order to compile the llvm-gcc frontend. The single problem is that mentioned in the previous message: 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 1. I have compiled the binutils for the arm-none-eabi target. Options:
