Makefile

# Makefile for a Linux/GCC build of CNTK
#
# The Linux and Windows versions are not different branches, but rather build off the same
# source files, using different makefiles. This current makefile has the purpose of enabling
# work to make all sources compile with GCC, and also to check for GCC-compat regressions due to
# modifications which are currently done under Windows.
#
# This makefile will be extended/completed as we go.
#
# To use this Makefile, create a directory to build in and make a Config.make in the directory
# that provides
# ACML_PATH= path to ACML library installation
#   only needed if MATHLIB=acml
# MKL_PATH= path to MKL library installation
#   only needed if MATHLIB=mkl
# GDK_PATH= path to cuda gdk installation, so $(GDK_PATH)/include/nvidia/gdk/nvml.h exists
#   defaults to /usr
# BUILDTYPE= One of release or debug
#   defaults to release
# MATHLIB= One of acml or mkl
#   defaults to acml
# CUDA_PATH= Path to CUDA
#   If not specified, GPU will not be enabled
# CUB_PATH= path to NVIDIA CUB installation, so $(CUB_PATH)/cub/cub.cuh exists
#   defaults to /usr/local/cub-1.4.1
# CUDNN_PATH= path to NVIDIA cuDNN installation so $(CUDNN_PATH)/cuda/include/cudnn.h exists
#   If not specified, CNTK will be be built without cuDNN.
# KALDI_PATH= Path to Kaldi
#   If not specified, Kaldi plugins will not be built
# OPENCV_PATH= path to OpenCV 3.0.0 installation, so $(OPENCV_PATH) exists
#   defaults to /usr/local/opencv-3.0.0
