[LLVMdev] Build problem, in com.h

[Reid Spencer]

Hi James,

You might find this document of help:
http://llvm.org/docs/CFEBuildInstrs.html 

gccas is part of llvm, not llvm-gcc. It needs to exist and be in your
path before building llvm-gcc.  As the CFEBuildInstrs.html indicate, you
need to

1. build llvm with "tools-only"
2. make sure $LLVM_OBJ_ROOT/Debug/bin is in your PATH
3. build llvm-gcc
4. build llvm with "install-bytecode"

Reid.
