Format not a string literal and no format arguments

From: http://ticktick.blog.51cto.com/823160/311614

I recently encountered the following problems during ortp source code compilation in Linux, but I did not find a good solution on the Internet. However, after some attempts, the problem was finally solved, take a note here ~~~

Compilation error: Error: format not a string literal and no format arguments

Environment where the error is generated:

Key point: the compiled file contains the following code:
Char * pteststr = "this is a test! ";
 
Printf (pteststr );

In addition, compilation errors often occur when the above Code is compiled in Ubuntu.

Solution:

Change the printf (pteststr) statement:

Printf ("% s", pteststr );

My system is Ubuntu 9.10 and GCC is 4.4.1, which may be caused by strict code check.
