similar to: [LLVMdev] LLVM-gcc for ARM

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.

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. Does that work for you? On Mon, Jan 18, 2010 at 2:52 PM, Viktor Kutuzov <vkutuzov at accesssoftek.com>wrote: > Hello Corina, > > I used a two-stage sequence to build the llvm and llvm-gcc

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.

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:

You need to configure with --enable-llvm. (It would still be nice if V1DI_pointer_node was defined; I'll take a look at that.)

Thanks for your tips. But I'm still getting errors. .../llvm-gcc4.2-2.6.source/configure --prefix=`pwd`/../install --program-prefix=llvm- --enable-llvm=/home/LLVM/llvm-2.6/ --enable-languages=c,c++  --with-gnu-ld=/home/arm/bin/arm-elf-ld --with-gnu-as=/home/arm/bin/arm-elf-as  --with-cpu=cortex-a8  --target=arm-elf Errors: >> checking for g++ that supports -ffunction-sections

Moreover,  ../llvm-gcc4.2-2.6.source/configure --prefix=`pwd`/../install --program-prefix=llvm- --enable-llvm=/home/LLVM/llvm-2.6/ --enable-languages=c,c++  --with-gnu-ld=/home/arm/bin/arm-elf-ld --with-gnu-as=/home/arm/bin/arm-elf-as  --with-arch=armv7  --target=arm-elf and then make target=arm-elf gives the following error: Unknown arch used in --with-arch=armv7 Thanks. --- On Sun,

> exec: 2: -meabi=4: not found > > Any ideas? Yes. As it can be deduced from the name of the package, it's for arm-none-linux-gnueabi, not for arm-eabi. Also, note that the mentioned package is too old for anything useful. -- With best regards, Anton Korobeynikov Faculty of Mathematics and Mechanics, Saint Petersburg State University

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

I recompiled the LLVM-gcc with these options: .../llvm-gcc4.2-2.6.source/configure --prefix=`pwd`/../install --program-prefix=llvm- --enable-llvm=/home/LLVM/llvm-2.6/ --enable-languages=c  --disable-libssp  --with-gnu-ld --with-gnu-as  --with-arch=armv7-a  --target=arm-elf It compiles successfuly. make install. But when compiling a file : llvm-gcc a.c Assembler messages: Fatal error: Invalid

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:

Hello, Well, I recompiled the LLVM-gcc .../llvm-gcc4.2-2.6.source/configure --prefix=`pwd`/../install --program-prefix=llvm- --enable-llvm=/home/LLVM/llvm-2.6/ --enable-languages=c  --disable-libssp  --with-gnu-ld=/home/LLVM/llvm-gcc4.2-2.6.source/arm-elf-ld --with-gnu-as=/home/LLVM/llvm-gcc4.2-2.6.source/arm-elf-as  --with-cpu=cortex-a8  --target=arm-elf Everything is OK, but when trying

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 *)

Can you be more specific? Where can I found it(arm-eabi)? please provide me with some basic steps.
