centos安装dlib

小心这个错误

c++: 编译器内部错误：已杀死(程序 cc1plus)     ＃ 内存不足，可解决的

复制如下命令：

yum install cmake python-devel numpy gcc gcc-c++ gtk2-devel libdc1394-devel libv4l-devel ffmpeg-devel gstreamer-plugins-base-devel libpng-devel libjpeg-turbo-devel jasper-devel openexr-devel libtiff-devel libwebp-devel opencv opencv-python opencv-devel

然后：

pip install dlib

ps：ffmpeg-devel 可能安装失败

1.可能不需要这步

配置Yum源为阿里源

备份：

mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup

配置：

cd /etc/yum.repos.d/

sudo  wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo

sudo yum makecache

删除/etc/yum.repos.d下的devtools-2.repo就恢复了

sudo mv devtools-2.repo devtools-2.repo.bat

2.

yum -y install epel-release

# Install the nux repository

rpm -Uvh http://li.nux.ro/download/nux/dextop/el7/x86_64/nux-dextop-release-0-5.el7.nux.noarch.rpm

yum install ffmpeg ffmpeg-devel -y
