llvm dev - Jul 2010 - [LLVMdev] Building LLVM 2.7 on OpenSolaris

I'm interested in using LLVM for compiling to x86_64 native code  
(ELF64), so I selected 'x86_64' as the architecture. I added
'host'
just-in-case...

The '--with-built-clang' selection is for building the Clang LLVM C  
compiler instead of using a gcc front end. I placed the Clang  
distribution in './tools/clang'.

You shouldn't need to do either of them.

You checked out clang into that directory or did something else?

-eric

I obtained the release as 'clang-2.7.tgz' from the official download  
site. I think the README says to move the compiler to the './tools/ 
clang' directory.

I'll remove '--enable-targets=host,x86_64' from configure and
attempt
a fresh build.
