注意：动态库与静态库的混合链接

Linux默认的链接是动态库，找不到动态库的情况下才会选择静态库；

使用方式为：gcc test.cpp -L. -ltestlib

如果当前目录有两个库libtestlib.so libtestlib.a 则肯定是连接libtestlib.so。如果要指定为连接静态库；
使用方式为：gcc test.cpp -L. -static -ltestlib

当对动态库与静态库混合连接的时候，使用-static会导致所有的库都使用静态连接的方式。这时需要作用-Wl的方式：
gcc test.cpp -L. -Wl,-Bstatic -ltestlib  -Wl,-Bdynamic -ltestlib

另外还要注意系统的运行库使用动态连接的方式，所以当动态库在静态库前面连接时，必须在命令行最后使用动态连接的命令才能正常连接，如：
gcc test.cpp -L. -Wl,-Bdynamic -ltestlib -Wl,-Bstatic -ltestlib  -Wl,-Bdynamic
