CentOS 6.5安装caffe注意事项 应该可以解决大部分报错问题

本文安装基本环境参考这篇博客，先往下看。

在我这里坑主要出现在安装glog一直报错（其实问题是gflag安装的问题），安装gflags的时候按照我这里的来

一句话：自己手动安装的包，一定要确保有且只有安装了这一个包(别重复安装)！

比如gflags:

首先先保证把老版本卸载：
1、如果之前用make install安装的，用make unistall卸载。
2、之后查看rpm包
rpm -qa | grep gflags
（我这里有两个 一个gflags和一个gflags-devel，卸载命令：sudo yum remove gflags）

wget https://github.com/schuhschuh/gflags/archive/master.zip 
unzip master.zip
cd gflags-master
mkdir build && cd build
export CXXFLAGS="-fPIC"
cmake .. -DGFLAGS_NAMESPACE=google
make
sudo make install

错误1：

如果提示缺少XXXX.so文件。

加入一个环境变量：

export LD_LIBRARY_PATH=/usr/local/lib

如果还提示缺少文件，把对应文件copy放进去。

错误2

caffe:/usr/bin/ld: cannot find -lcblas

sudo yum install atlas-devel

在Makefile.config中加入：

BLAS_INCLUDE := /usr/include
BLAS_LIB := /usr/lib64/atlas

足足搞了一整天，把可能忽略的地方写出来，希望可以对您有所帮助。

我的是CPU-ONLY的，caffe的配置如下：

## 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

# CPU-only switch (uncomment to build without GPU support).
CPU_ONLY := 1

# 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++

# CUDA directory contains bin/ and lib/ directories that we need.
#CUDA_DIR := /usr/local/cuda
# 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_50,code=sm_50 \
#       -gencode arch=compute_50,code=compute_50

# BLAS choice:
# atlas for ATLAS (default)
# mkl for MKL
# open for OpenBlas
BLAS := atlas
# Custom (MKL/ATLAS/OpenBLAS) include and lib directories.
# Leave commented to accept the defaults for your choice of BLAS
# (which should work)!

最后来一个运行成功截图嘚瑟下。
