本文，试图中一个干净的ubuntu14.04机器上安装caffe的cpu版本。
http://blog.csdn.net/sinat_35188997/article/details/73530434
http://caffe.berkeleyvision.org/installation.html
http://blog.csdn.net/zly_kemgine/article/details/78749764
首先卸载掉一些包：
卸载所有cuda有关的包：
apt-get remove --purge cuda-*
卸载掉所有nvidia有关的包：
apt-get remove --purge nvidia-*
卸载掉所有cudnn包：
apt-get remove --purge libcudnn*
卸载掉所有caffe包：
apt-get remove --purge caffe-*
卸载掉conda：
直接删除conda安装目录，然后在环境变量配置文件中删除旧路径即可http://blog.csdn.net/qq_22474567/article/details/54984257
然后使用dpkg -l|grep 或 dpkg -S 软件名 或 find 查看是否卸载干净
因为我是用的是什么都没有的干净的ubuntu系统，所以免去上面的步骤。
然后安装conda：
上官网下载.sh文件，运行，运行过程中配置一下安装目录，确认一下是否要加入环境变量即可，安装完成后重启terminal即可使用
对于caffe的依赖包有哪些，请参考Prerequisites：http://caffe.berkeleyvision.org/installation.html
然后安装openblas：
源码：https://github.com/xianyi/OpenBLAS
安装教程：http://www.tuicool.com/articles/vimi6v
下载openblas源码，解压，进入目录，
make
make完成后，根据输出中的提示，修改Makefile.rule文件中的prefix字段，设置安装目录，然后执行，
make install
（或者也可以直接执行 make PREFIX=安装路径 install 命令）
然后安装protobuf：
注意，caffe暂不支持protobuf3，我们一般选择安装protobuf 2.5.0
源码：https://github.com/google/protobuf
安装教程：http://blog.csdn.net/10km/article/details/53023527
http://blog.csdn.net/nyist327/article/details/49908891
http://blog.csdn.net/missdaddio/article/details/67631777
官方教程上说，直接
$ ./configure --prefix=安装路径
$ make -j16
$make check -j16
$ make install
但是，解压后发现没有configure文件，上网搜索后发现，需要先运行autogen.sh生成configure文件
运行autogen.sh，发现程序试图从一个被墙的网站上下载gtest-1.5.0.tar.bz2，因为机器不能FQ，所以无法下载。
查看autogen.sh的代码，发现下面这段代码：
于是手动下载googletest-release-1.5.0.zip,解压缩后，改名为gtest放在protobuf-2.5.0目录下
再次运行autogen.sh，再次出错
/autogen.sh: 40: autoreconf: not found
搜了一下，发现是因为缺包
解决办法： sudo apt-get install autoconf automake libtool
再次运行autogen.sh，成功生成configure，然后
$ ./configure --prefix=安装路径
$ make -j16
$make check -j16
$ make install
最后运行protoc命令，查看是否安装成功
然后，安装到anaconda中
export PATH=/HOME_ANACONDA_PATH/bin:PATH
#cd ./python
#python setup.py build
#python setup.py test
#python setup.py install
正确安装如图：
然后安装boost：
源码：http://www.boost.org/users/history/version_1_66_0.html（这里注意，不要用github上下载的zip，github上下载下来的zip不全，会报can't cd into ...错误）
教程：
./bootstrap.sh --prefix=/usr --with-python=/opt/anaconda2/bin/ --with-python-root=/opt/anaconda2/
./b2
./b2 install
然后安装glog
源码：https://github.com/google/glog/tree/v0.3.3
教程：
tar zxvf glog-0.3.3.tar.gz
cd glog-0.3.3
./configure ¨C-prefix=/usr
make && make install
然后安装gflags
源码：https://github.com/gflags/gflags
教程：
要先安装cmake：apt-get update & apt-get install cmake
cd gflags-master
mkdir build
cd build
export CXXFLAGS="-fPIC"
cmake -D CMAKE_INSTALL_PREFIX=/usr .. （这里注意最后的两个点，别漏了）
make VERBOSE=1
make
make install
然后安装hdf5
源码：https://support.hdfgroup.org/HDF5/release/obtainsrc518.html
教程：
tar -zxvf hdf5-1.8.3.tar.gz
$ ./configure --prefix=/usr
make
make check # run test suite.
make install
make check-install # verify installation.
然后安装snappy
源码：http://google.github.io/snappy/
教程：https://github.com/google/snappy/blob/master/README.md
cd google-snappy-4f7bd2d
mkdir build
cd build
（export CXXFLAGS='-fPIC'）——这句后来被证明应该加上，以便在编译时产生share文件夹
cmake -D CMAKE_INSTALL_PREFIX=/usr ..
make
make install
然后安装opencv（这里注意一下，尽量编译安装opencv3。我尝试过直接用conda install opencv而不使用编译安装，结果在安装caffe时存在一些问题）
源码：https://github.com/opencv/opencv/tree/3.0.0
教程：https://www.cnblogs.com/kanuore/p/7587434.html（这个是给python3安装opencv的，2同理）
下载源码，解压，进入目录，发现是cmake的项目，故创建build文件夹并在其中cmake。
mkdir build
cd build
执行cmake命令，如下图：
发现报错，如下图，一开始进入CMakeError.log文件中查看，发现有错误提示提到ffmpeg等。以为是缺包，因此安装缺少的包：http://blog.csdn.net/zhang_shuai12/article/details/52289825
sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev
再次执行camke命令，还是报一样的错。
然后仔细阅读了错误提示中的内容，发现程序试图从一个被墙的网站下载ippicv_linux_20141027.tgz，下载不下来因此报错！
一定要仔细阅读错误提示！如果错误提示看不出什么的话再去看CMakeError.log文件。
根据上面的错误提示，查看3rdparty/ippicv/downloader.cmake文件，或者根据网上搜到的结果，发现需要手动下载ippicv_linux_20141027.tgz并放到指定位置（如下图）
于是从github上下载ippicv_linux_20141027.tgz，https://github.com/pkpp1233/ippicv，下载后解压得到所需压缩包，拷贝到指定文件夹中。
再次执行cmake命令，cmake通过，然后make，makeinstall，都成功了。
但是，因为我在cmake命令中指定了将opencv安装到anaconda中的python中，因此想要在python中看一下opencv是否安装成功
import cv2
结果import失败。这个包并没有被安装上。
回过头来思考，可能是cmake命令的选项出错了，因此仔细阅读了cmakelist，发现cmake命令中的的选项都在CMakeLists.txt中有解释，之前的cmake命令中好多选项写错了：
1、用ctrl查找，发现cublas是cuda的配置，应该不需要，去掉
2、查找之前输入的选项，发现有几个选项查找不出来，则说明是选项名字错了，比如PYTHON_EXECUTEABLE应该为PYTHON2_EXECUTEABLE，PYTHON_LIBRARY应为PYTHON2_LIBRARIES……逐个选项修复
错误的cmake命令：
得到正确的cmake命令：
删掉生成的/opt/opencv，删掉编译目录build，重新mkdir build，cd build，执行正确的cmake命令，make，make install。都通过了。
然后测试import cv2，成功。
总结：
cmake命令安装的时候一定要仔细阅读cmakelist.txt文件
然后安装lmdb
源码：https://github.com/LMDB/lmdb
教程：
git clone https://github.com/LMDB/lmdb
cd lmdb/libraries/liblmdb
打开makefile文件，修改prefix字段
make && make install
（或使用make install DESTDIR=/root/_install_caffe_cpu/lmdb命令）
然后安装leveldb
源码：https://github.com/google/leveldb/tree/v1.10
教程：
解压，进入文件夹
make
make命令发现报错：
在github上发现了关于相似问题的讨论，只不过我们是snappy库报的错，它是gflags库报的错：https://github.com/BVLC/caffe/issues/2171
原来是当时安装snappy的时候应该先执行一句export CXXFLAGS='-fPIC'，这样编译后才会生成share文件夹。
所以重新安装snappy：删除build文件夹，mkdir build，cd build，export CXXFLAGS='-fPIC'，cmake -D CMAKE_INSTALL_PREFIX=/usr ..，make，make install
make install，发现报错，原来leveldb的工具包不支持make install（查看makefile文件，可以发现找不到install命令的定义）
所以需要手动将make出的.a和.so文件拷贝到/usr/lib下，将include文件夹拷贝到/usr/include下
最后，安装caffe：
解压，进入caffe-master，官方推荐使用make方式编译caffe，也可以使用cmake，这里我用make
复制一份Makefile.config.example，改名为Makefile.config
根据自己的需要，修改makefile.config，以下是我的配置：
## Refer to http://caffe.berkeleyvision.org/installation.html

$(ANACONDA_HOME)/include/python2.7

Q ?= @
修改完成后，
make all
make pycaffe
make test
然后将caffe源码目录中的python文件夹配置到PYTHONPATH这个环境变量里面去（如下图）←注意别漏了这一步
make方式编译的caffe不需要install，直接使用解压的这个文件夹里的东西
测试一下caffe：
测试一下pycaffe：
成功！
