#-fpic acts on the compile phase, telling the compiler to generate location-independent code
The #-D macro definition, equivalent to the global # define in C, can be used to control the compilation of the source program through macro definitions, for example:
# #ifdef _fileline
# printf ("Hello Yu Qiang, How is you?\n");
# #else
# printf ("Sorry to Lost. \ n ");
# #endif
# program Final call output is: Hello Yu Qiang, how is it?
