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
