[LLVMdev] Problems compiling llvm-gcc4 frontend on x86_64

Thu May 24 22:34:59 PDT 2007

Hi all,

I've run into problems compiling the llvm-gcc frontend on x86_64.  Is this
not supported, or am I making an error somewhere?

The procedure I followed was:

1. Download LLVM 2.0 source as a tarball (from a few days ago, during
the testing phase).
2. Download the llvm-gcc4 source today, as a tarball.
3. Extract both. 

4. Configure LLVM as: ../src/configure --prefix=`pwd`../install
--enable-optimized --enable-jit --enable-targets=host-only
(There is no llvm-gcc in the path)
5. make ENABLE_OPTIMIZED=1

6. Configure the frontend as:
../llvm-gcc4-2.0.source/configure --prefix=`pwd`../install
--program-prefix=llvm- --enable-llvm=/home/warren/llvm/obj/
--enable-languages=c,c++ --disable-shared

7. make LLVM_VERSION_INFO=2.0

This produced errors from the assembler.  I reran the failing command
with -v, and got the output below.
I then changed the command to use -S instead of -c, the resulting
assembler is attached.

Any advice gratefully received.

Cheers,
Warren
