CentOS编译安装emacs 25.3 错误 make: *** No targets specified and no makefile found. Stop.

今天在一台很久没有动过的vps上编译安装emacs 25.3时，遇到 make: *** No targets specified and no makefile found. Stop.错误

其实解决起来很简单，就是需要先 yum update 一下。整个过程如下：

yum update
cd /usr/loca/src
wget http://mirrors.ustc.edu.cn/gnu/emacs/emacs-25.3.tar.gz 
tar -xvf ~/emacs-25.3.tar.gz 

安装依赖库

yum install gcc* glib* gtk* ncurses* libXpm* giflib* libjpeg* libtiff* libpng* -y

mkdir emacs_build      
cd emacs_build/
sudo../emacs-25.1/configure
sudo make && sudo make install

默认会安装在 /usr/local/bin 下, 如果它没有添加在你的环境变量中，需要修改 /etc/profile 文件，在文件末尾加上如下两行代码 

PATH=$PATH:/usr/local/bin 
export PATH

然后运行 

source /etc/profile

emacs --version

就可以看到如下信息：

[ emacs_build]# emacs --version
