Compiler Option: -pic

Generate position-independent code (non-x86 Unix shared libs)

Syntax
   -pic

Description
   The -pic compiler option tells the compiler to generate 
   position-independent code. This is needed for creating shared libraries 
   on x86_64 or ARM Linux/BSD platforms except Win64 (and also not on 32bit 
   x86). This option should not be used when creating executables (as 
   opposed to shared libraries) though.

   By default, -pic is enabled when using -dll or -dylib, and disabled for 
   all other compilation modes. Usually you only have to specify -pic if 
   you are using -c or -lib and want to link them into shared libraries 
   later.

   -pic is implemented by passing -fPIC to gcc (when using the -gen gcc 
   backend). The -gen gas backend does not support position-independent 
   code since it only supports 32bit x86 and there is no special 
   position-independent code needed for shared libraries on 32bit x86.
