# Compiling and linking against in tree libraries.
|
|
#
|
|
# In order to compile and link against an in-tree library various
|
|
# cpp/compiler/linker options are required.
|
|
#
|
|
# For example consider a library "libfoo" which itself uses two other
|
|
# libraries:
|
|
# libbar - whose use is entirely internal to libfoo and not exposed
|
|
# to users of libfoo at all.
|
|
# libbaz - whose use is entirely internal to libfoo but libfoo's
|
|
# public headers include one or more of libbaz's
|
|
# public headers. Users of libfoo are therefore transitively
|
|
# using libbaz's header but not linking against libbaz.
|
|
#
|
|
# SHDEPS_libfoo: Flags for linking recursive dependencies of
|
|
# libfoo. Must contain SHLIB for every library which
|
|
# libfoo links against. So must contain both
|
|
# $(SHLIB_libbar) and $(SHLIB_libbaz).
|
|
#
|
|
# SHLIB_libfoo: Flags for recursively linking against libfoo. Must
|
|
# contains SHDEPS_libfoo and:
|
|
# -Wl,-rpath-link=<directory containing libfoo.so>
|
|
#
|
|
# CFLAGS_libfoo: Flags for compiling against libfoo. Must add the
|
|
# directories containing libfoo's headers to the
|
|
# include path. Must recursively include
|
|
# $(CFLAGS_libbaz), to satisfy the transitive inclusion
|
|
# of the headers but not $(CFLAGS_libbar) since none of
|
|
# libbar's headers are required to build against
|
|
# libfoo.
|
|
#
|
|
# LDLIBS_libfoo: Flags for linking against libfoo. Must contain
|
|
# $(SHDEPS_libfoo) and the path to libfoo.so
|
|
#
|
|
# Consumers of libfoo should include $(CFLAGS_libfoo) and
|
|
# $(LDLIBS_libfoo) in their appropriate directories. They should not
|
|
# include any CFLAGS or LDLIBS relating to libbar or libbaz unless
|
|
# they use those libraries directly (not via libfoo) too.
|
|
#
|
|
# Consumers of libfoo should not directly use $(SHDEPS_libfoo) or
|
|
# $(SHLIB_libfoo)
