之前在ubuntu14下实现了Caffe编译(参见去年写的博客 《 Ubuntu14:cmake生成Makefile编译caffe过程(OpenBLAS/CPU only)》)。
最近将系统升级到ubuntu16,新电脑显示也支持CUDA了，重新编译Caffe时发现还依赖库还是有点不同，在这里记下来。

硬件配置

神舟Z7M-SL7D2笔记本
cpu Core i7-6700HQ(含集成显卡)
芯片组 Intel Hm170
独立显卡 NVIDIA GTX965M

软件环境

ubuntu 16.04
NVIDIA driver 378
CUDA8.0
cudnn 5.1

编译环境准备

安装编译Caffe所需的依赖库

#!/bin/bash
sudo apt-get install cmake
sudo apt-get install libprotobuf-dev protobuf-compiler libleveldb-dev libsnappy-dev libopencv-dev libhdf5-serial-dev 
sudo apt-get install libboost-all-dev   // 安装boost库
#sudo apt-get install libatlas-base-dev //BLAS如使用OpenBLAS，可不安装
sudo apt-get install libopenblas-dev    //BLAS如使用atlas，可不安装
sudo apt-get install libgflags-dev libgoogle-glog-dev liblmdb-dev
sudo apt-get install python-numpy  // 安装numpy
#sudo apt-get install doxygen // doxygen用于文档生成 可不安装

编译caffe

以下是编译caffe的脚本(解压，生成Makefile，编译，安装全过程)
build_caffe.sh

#!/bin/bash
caffe_folder=caffe-master
if [ -d $caffe_folder ]
then 
    rm -fr $caffe_folder
fi
# 从 https://github.com/BVLC/caffe 下载Caffe源码 caffe-master.zip解压缩
unzip $caffe_folder.zip 
pushd $caffe_folder
# 创建编译输出文件夹
mkdir build && cd build
# 执行cmake生成Makefile
#编译cpu版本
#cmake -Dcpu_ONLY=ON -DBLAS=Open ..
#编译GPU版本
cmake -DBLAS=Open -DCUDA_NVCC_FLAGS=--Wno-deprecated-gpu-targets .. 
# 开始编译并安装到build/install文件夹下 并发8线程
make install -j 8
cd ..
popd

消除NVCC警告

在这里 -DCUDA_NVCC_FLAGS=--Wno-deprecated-gpu-targets用于指定CUDA编译器(nvcc)的编译选项，如果不指定--Wno-deprecated-gpu-targets选项则在编译Caffe时会产生如下编译警告

nvcc warning : The ‘compute_20’,‘sm_20’,and ‘sm_21’ architectures are deprecated,and may be removed in a future release (Use -Wno-deprecated-gpu-targets to suppress warning).

当然也可以在cmake-gui中，如下图搜索NVCC，在CUDA_NVCC_FLAGS中添加--Wno-deprecated-gpu-targets

执行cmake -DBLAS=Open -DCUDA_NVCC_FLAGS=--Wno-deprecated-gpu-targets ..输出如下
