   6 # The 'cc-shared' module provides support for shared libraries and shared objects.
   7 # It defines the following variables:
   8 #
   9 ## SH_CFLAGS         Flags to use compiling sources destined for a shared library
  10 ## SH_LDFLAGS        Flags to use linking a shared library
  11 ## SHOBJ_CFLAGS      Flags to use compiling sources destined for a shared object
  12 ## SHOBJ_LDFLAGS     Flags to use linking a shared object
  13 ## SH_LINKFLAGS      Flags to use linking an executable which will load shared objects
  14 ## LD_LIBRARY_PATH   Environment variable which specifies path to shared libraries
