   5 #
   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 (creating) a shared library
  11 ## SH_SOPREFIX       Prefix to use to set the soname when creating a shared library
  12 ## SH_SOFULLPATH     Set to 1 if the shared library soname should include the full install path
  13 ## SH_SOEXT          Extension for shared libs
  14 ## SH_SOEXTVER       Format for versioned shared libs - %s = version
  15 ## SHOBJ_CFLAGS      Flags to use compiling sources destined for a shared object
  16 ## SHOBJ_LDFLAGS     Flags to use linking a shared object, undefined symbols allowed
  17 ## SHOBJ_LDFLAGS_R   - as above, but all symbols must be resolved
  18 ## SH_LINKRPATH      Format for setting the rpath when linking an executable, %s = path
  19 ## SH_LINKFLAGS      Flags to use linking an executable which will load shared objects
  20 ## LD_LIBRARY_PATH   Environment variable which specifies path to shared libraries
  21 ## STRIPLIBFLAGS     Arguments to strip a dynamic library
