在上两篇文章中已经简单介绍了用scons编译库文件，可执行程序的方法，本篇中将主要介绍scons的其他一些常用参数以及变量。
scons不带参数执行的时候会执行编译动作，对于内容改变过的源文件它会自动重新编译，scons对文件状态的改变靠的是内容的md5而不是时间戳，这是scons和makefile不同的一点。它对文件信息和状态的记录保存在当前目录下的.sconsign.dblite文件中。
scons最常用的参数有两个，-c和-Q。
scons -c可]]>https://blog.youkuaiyun.com/Falcon2000/article/details/6363293https://blog.youkuaiyun.com/Falcon2000/article/details/6363293Falcon2000Tue, 26 Apr 2011 09:31:00 +0800
本篇文章接着上一篇进一步介绍scons的使用方法，主要介绍静态库和动态库的编译
在scons里编译库文件和编译可执行程序非常类似，只是采用的指令有所不同。
对于静态库，采用如下指令
Library(”libdemo”,["a.c","b.c"])或者StaticLibrary(”libdemo”,["a.c","b.c"])
对于动态库，采用如下指令
SharedLibrary(”libdemo”,["a.c","b.c"])
