mac 下安装caffe(一）

1.brew install --build-from-source -vd boost boost-python

这一步出错：libtool: unrecognized option `-static'

编译过程中调用了"libtool" -static -o "xx.a" "xxx.o" 命令进行静态链接。

MERRICKMEI-MB0:/ merrickmei$ brew unlink libtool
Unlinking /usr/local/Cellar/libtool/2.4.6_1...  symlinks removed
MERRICKMEI-MB0:/ merrickmei$ which libtool
/usr/local/bin/libtool
MERRICKMEI-MB0:/ merrickmei$ whereis libtool
/usr/bin/libtool

MERRICKMEI-MB0:/ merrickmei$ /usr/local/bin/libtool   -static -o
libtool: unrecognized option `-static'
libtool: Try `libtool --help' for more information.

 MERRICKMEI-MB0:/ merrickmei$ /usr/bin/libtool   -static -o
error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: missing argument to: -o option
Usage: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool -static [-] file [...] [-filelist listfile[,dirname]] [-arch_only arch] [-sacLT] [-no_warning_for_no_symbols]

MERRICKMEI-MB0:/ merrickmei$ ls -l /usr/local/bin/libtool
-rwxrwxrwx   root  admin      : /usr/local/bin/libtool

可见，/usr/local/bin/libtool不支持-static,而/usr/bin/libtool支持-static选项。

MERRICKMEI-MB0:/ merrickmei$  /usr/local/bin/libtool  --version
ltmain.sh (GNU libtool) 2.2.6b
Written by Gordon Matzigkeit <gord@gnu.ai.mit.edu>, 

/usr/local/bin/libtool 是之前自己make install手动编译安装的。
而/usr/bin/libtool 是xcode自带的。

同样make uninstall libtool:
cd libtool-2.2.6b
./configure --prefix=/usr/local
make
sudo make uninstall

虽然有错误，但是/usr/local/bin/libtool 已经不见了。which libtool，whereis libtool都只显示/usr/bin/libtool

再次执行brew install --build-from-source -vd boost boost-python 就发现ok了，continue...

2.Python接口,进入caffe/python目录

for req in $(cat requirements.txt); do pip install $req; done

3.make

Makefile.config中去掉CPU_ONLY := 1的注释

cp Makefile.config.example Makefile.config
make all
make test
make runtest

make runtest出现绿色RUN OK

4.pycaffe

 MERRICKMEI-MB0:caffe merrickmei$ make pycaffe
CXX/LD -o python/caffe/_caffe.so python/caffe/_caffe.cpp
python/caffe/_caffe.cpp::: fatal error: 'numpy/arrayobject.h' file not found
#include <numpy/arrayobject.h>

解决：将numpy/arrayobject.h所在的路径/usr/local/lib/python2.7/site-packages/numpy/core/include 添加到

Makefile.config中的PYTHON_INCLUDE

PYTHON_INCLUDE := /usr/include/python2.7 \
/usr/lib/python2.7/dist-packages/numpy/core/include\
/usr/local/lib/python2.7/site-packages/numpy/core/include

再次 make clean,make pycaffe,成功编译。。

添加caffe到PYTHONPATH

export PYTHONPATH=$PYTHONPATH:/Users/work/gitclone/caffe/python

numpy解决后再import caffe 有碰到错误：

ImportError: No module named skimage.io

因为使用的系统的python，而不是Anaconda Python，决定还是用Anaconda Python
