Makefile

# The following variables will likely need to be modified, depending on where
# and how you built LLVM & Clang. They can be overridden in a command-line
# invocation of make, like:
#
#   make LLVM_SRC_PATH=<path> LLVM_BUILD_PATH=<path> ...
#

# LLVM_SRC_PATH is the path to the root of the checked out source code. This
# directory should contain the configure script, the include/ and lib/
# directories of LLVM, Clang in tools/clang/, etc.
# Alternatively, if you're building vs. a binary download of LLVM, then
# LLVM_SRC_PATH can point to the main untarred directory.
LLVM_SRC_PATH ?= $$HOME/llvm/llvm_svn_rw

# LLVM_BUILD_PATH is the directory in which you built LLVM - where you ran
# configure or cmake.
# For linking vs. a binary build of LLVM, point to the main untarred directory.
# LLVM_BIN_PATH is the directory where binaries are placed by the LLVM build
# process. It should contain the tools like opt, llc and clang. The default
# reflects a debug build with autotools (configure & make).
LLVM_BUILD_PATH ?= $$HOME/llvm/build/svn-make-debug
