[LLVMdev] llvm-gcc cross compiling for ARM

[James Molloy]

Hi Yuvi,

crt{i,n,begin,end,0,1}.o are runtime objects that are OS-dependent. Are you compiling for baremetal or arm-linux?

If baremetal, you'd need to put your core startup code  in crt1.o, and create stub objects for the rest so the linker doesn't complain (touch test.c; clang -march=armv7 -c -o test.o test.c; cp test.o crt{i,n,begin,end}.o).

Cheers,

James

Hi

I am trying to cross compile llvm-gcc front for ARM target

Followed below steps


#../llvm-gcc-4.2-2.9.source/configure --program-prefix=llvm- --enable-llvm=/home/yuvraj/llvm/llvm-2.9 --enable-languages=c,c++ --target=arm-none-linux-gnueabi

# make

I am getting some kind of linker errors

/opt/arm-2010.09/bin/arm-none-linux-gnueabi-ld: cannot find crtn.o: No such file or directory



@ final stage.

I copied  crtn.o to current working directory. But getting same issue

How do i resolve this issue?


Thanks

Yuvi R
