Preface

Put the project in hand into pf_ring, organize a Makefile template, and make a template for the later test project of pf_ring.

Think of the Makefile content previously posted on the blog, copy and paste it to the local Makefile, and then r\n appears at the end, causing Makefile to not run.
There are two simple ways to solve this problem:
* Install dos2unix and use dos2unix -n make_file_path_name make_file_path_name_new to replace r n with R.
When you encounter a complex Makefile, dos2unix recognizes binary characters (actually, there is no binary character, it is a bug in dos2unix), which makes it impossible to convert.

centos : yum install dos2unix unix2dos

ubuntu : aptitude install tofrodos
unix2dos Corresponding todos   dos2unix Corresponding fromdos

• Use Source Insight 4.0 to paste the Makefile and save it as a unix return file. This method is very simple.
