## Refer to http://caffe.berkeleyvision.org/installation.html# Contributions simplifying and improving our build system are welcome!# cuDNN acceleration switch (uncomment to build with cuDNN).# USE_CUDNN := 1"CuDNN是NVIDIA专门针对Deep Learning框架设计的一套GPU计算加速库，用于实现高性能的并行计算,在有GPU并且安装CuDNN的情况下可以打开即将注释去掉。"# CPU-only switch (uncomment to build without GPU support).#CPU_ONLY := 1"表示是否用GPU,如果只有CPU这里要打开"# uncomment to disable IO dependencies and corresponding data layersUSE_OPENCV := 1"因为要用到OpenCV库所以要打开，下面这两个选项表示是选择Caffe的数据管理第三方库，两者都不打开 Caffe默认用的是LMDB，这两者均是嵌入式数据库管理系统编程库。"# USE_LEVELDB := 0# USE_LMDB := 0# uncomment to allow MDB_NOLOCK when reading LMDB files (only if necessary)# You should not set this flag if you will be reading LMDBs with any# possibility of simultaneous read and write# ALLOW_LMDB_NOLOCK := 1"当需要读取LMDB文件时可以取消注释，默认不打开。"# Uncomment if you're using OpenCV 3OPENCV_VERSION := 2.4.10"用pkg-config --modversion opencv命令查看opencv版本"# To customize your choice of compiler, uncomment and set the following.# N.B. the default for Linux is g++ and the default for OSX is clang++# CUSTOM_CXX := g++"linux系统默认使用g++编译器，OSX则是clang++。"# CUDA directory contains bin/ and lib/ directories that we need.CUDA_DIR := /usr/local/cuda"CUDA的安装目录"# On Ubuntu 14.04, if cuda tools are installed via# "sudo apt-get install nvidia-cuda-toolkit" then use this instead:# CUDA_DIR := /usr# CUDA architecture setting: going with all of them.# For CUDA < 6.0, comment the *_50 lines for compatibility.CUDA_ARCH := -gencode arch=compute_20,code=sm_20 \        -gencode arch=compute_20,code=sm_21 \        -gencode arch=compute_30,code=sm_30 \        -gencode arch=compute_35,code=sm_35 \        -gencode arch=compute_50,code=sm_50 \        -gencode arch=compute_50,code=compute_50"这些参数需要根据GPU的计算能力(http://blog.csdn.net/jiajunlee/article/details/52067962)来进行设置，6.0以下的版本不支持×_50的计算能力。"# BLAS choice:# atlas for ATLAS (default)# mkl for MKL# open for OpenBlasBLAS := open"如果用的是ATLAS计算库则赋值atlas，MKL计算库则用mkl赋值，OpenBlas则赋值open。"# Custom (MKL/ATLAS/OpenBLAS) include and lib directories.# Leave commented to accept the defaults for your choice of BLAS# (which should work)!BLAS_INCLUDE := /usr/local/OpenBlas/includeBLAS_LIB := /usr/local/OpenBlas/lib"blas库安装目录"# Homebrew puts openblas in a directory that is not on the standard search path# BLAS_INCLUDE := $(shell brew --prefix openblas)/include# BLAS_LIB := $(shell brew --prefix openblas)/lib"如果不是安装在标准路径则要指明"# This is required only if you will compile the matlab interface.# MATLAB directory should contain the mex binary in /bin.# MATLAB_DIR := /usr/local# MATLAB_DIR := /Applications/MATLAB_R2012b.app"matlab安装库的目录"# NOTE: this is required only if you will compile the python interface.# We need to be able to find Python.h and numpy/arrayobject.h.PYTHON_INCLUDE := /usr/include/python2.7 \        /usr/lib/python2.7/dist-packages/numpy/core/include"python安装目录"# Anaconda Python distribution is quite popular.
