CROSS COMPILING LLVM

I was able to use your scripts to build llvm and llvm-gcc successfully. But when i try to link to llvm libraries i get the following :



/arm-2007q3/bin/…/lib/gcc/arm-none-linux-gnueabi/4.2.1/…/…/…/…/arm-none-linux-gnueabi/bin/ld: /arm-llvm/llvm-project/i686-pc-linux-gnu/arm-none-linux-gnueabi/llvm/lib/LLVMXCore.o: Relocations in generic ELF (EM: 3)
/arm-llvm/llvm-project/i686-pc-linux-gnu/arm-none-linux-gnueabi/llvm/lib/LLVMXCore.o: could not read symbols: File in wrong format

Thanks

What are you trying to do, exactly? If you’re trying to create an ARM executable which uses LLVM libraries, note that you’d have to also cross-compile LLVM first, using your new cross-compiler. Otherwise, you’re trying to link ARM object files with x86_64 LLVM libraries, which aren’t compatible.

Note that I’m just guessing – it’s really hard to tell what’s wrong without complete information, e.g. exact command lines, your host machine, your target machine, etc.
