Sounds promising, but here: [root <at> maple clang]# make -j3 Makefile:4: ../../Makefile.common: No such file or directory make: *** No rule to make target `../../Makefile.common'. Stop.
You need to run get LLVM and run configure first. Here's a "quick start guide" which should work. First steps: get LLVM and build it. You don't need llvm-gcc, and you don't need to do make install. I'd strongly suggest building it with objdir=srcdir. $ svn co http://llvm.org/svn/llvm-project/llvm/trunk llvm $ cd llvm $ ./configure $ make This will build LLVM in debug mode. I suggest adding llvm/Debug/bin to your path, which will give you utilities like llvm-as, llc, lli, etc. All of these have --help options, and all the LLVM utilities have pages here: http://llvm.org/docs/CommandGuide/ . Once you have this, check out the clang front-end. Continuing the above: $ cd tools $ svn co http://llvm.org/svn/llvm-project/cfe/trunk clang $ cd clang $ make the make command will build the llvm/Debug/bin/clang tool, which is the front-end. Once you have the clang tool, there are a bunch of different options for different things (see clang --help): you can parse and pretty print C code, run the preprocessor, etc. There are a variety of GCC compatible options. One main feature of the front-end is that we produce excellent diagnostics, particularly for type checking errors etc. This work is still somewhat early on. In particular, our C++ support is very minimal at this point. That said, we have a great foundation, architecture, and a commitment to seeing it through.
