ask for help：I want to compile a dynamic library file, such as libpsqlodbc w.so

[张进涛]

hello!
    I compile code on linux and find that when I compile it, it is a static 
library file by default, 
but I want to compile a dynamic library file, such as libpsqlodbcw.so. How 
should I set the compilation options，or what should i do?
