# @synopsis:
|
|
#
|
|
# The 'cc-shared' module provides support for shared libraries and shared objects.
|
|
# It defines the following variables:
|
|
#
|
|
## SH_CFLAGS Flags to use compiling sources destined for a shared library
|
|
## SH_LDFLAGS Flags to use linking (creating) a shared library
|
|
## SH_SOPREFIX Prefix to use to set the soname when creating a shared library
|
|
## SH_SOFULLPATH Set to 1 if the shared library soname should include the full install path
|
|
## SH_SOEXT Extension for shared libs
|
|
## SH_SOEXTVER Format for versioned shared libs - %s = version
|
|
## SHOBJ_CFLAGS Flags to use compiling sources destined for a shared object
|
|
## SHOBJ_LDFLAGS Flags to use linking a shared object, undefined symbols allowed
|
|
## SHOBJ_LDFLAGS_R - as above, but all symbols must be resolved
|
|
## SH_LINKRPATH Format for setting the rpath when linking an executable, %s = path
|
|
## SH_LINKFLAGS Flags to use linking an executable which will load shared objects
|
|
## LD_LIBRARY_PATH Environment variable which specifies path to shared libraries
|
|
## STRIPLIBFLAGS Arguments to strip a dynamic library
|
