# These are the variables that are used in Makefile, pcap-config, and
# libpcap.pc.
#
# CFLAGS: inherited from the environment, not modified by us except
# for flags required for the platform for which we're building (and
# except temporarily during tests that involve compilation). Used only
# when compiling C source.
#
# LDFLAGS: inherited from the environment, not modified by us.
#
# LIBS: inherited from the environment; we add libraries required by
# libpcap. Libraries that the core libpcap code requires are added
# first; libraries required by additional pcap modules are first
# added to ADDITIONAL_LIBS, and only added to LIBS at the end, after
# we're finished doing configuration tests for the modules.
#
# LIBS_STATIC: libraries with which a program using the libpcap *static*
# library needs to be linked. This is a superset of LIBS, used in
# pcap-config, so that "pcap-config --libs --static" will report them.
# Initialized to LIBS.
#
# REQUIRES_PRIVATE: pkg-config package names for additional libraries
# with which a program using the libpcap *static* library needs to be
# linked and for which a .pc file exists. This is used in libpcap.pc,
# so that "pkg-config --libs --static" will report them, and so that
# those libraries will be determined using the library's .pc file, not
# from our .pc file. Initialized to an empty string.
#
# V_CCOPT: additional compiler flags other than -I and -D flags
# needed when compiling libpcap. Used in Makefile for both C and
# C++ source.
#
# V_DEFS: additional -D compiler flags needed when compiling
# libpcap. Used in Makefile for both C and C++ source.
#
# V_INCLS: additional -I compiler flags needed when compiling
# libpcap. Used in Makefile for both C and C++ source.
#
# ADDITIONAL_LIBS: additional libraries with which the libpcap dynamic
# library needs to be linked. Used in Makefile; not used in pcap-config
# or libpcap.pc, as, in all platforms on which we run, if a dynamic
# library is linked with other dynamic libraries, a program using
# that dynamic library doesn't have to link with those libraries -
# they will be automatically loaded at run time. Initialized to an
# empty string.
#
# ADDITIONAL_LIBS_STATIC: additional libraries with which a program
# using the libpcap *static* library needs to be linked. This is used
# in pcap-config, so that "pcap-config --libs --static" will report
# them. Initialized to an empty string.
#
# REQUIRES_PRIVATE: pkg-config package names for additional libraries
# with which a program using the libpcap *static* library needs to be
# linked and for which a .pc file exists. This is used in libpcap.pc,
# so that "pkg-config --libs --static" will report them, and so that

#
# LIBS_PRIVATE: pkg-config package names for additional libraries with

# and for which a .pc file does not exist. This is used in libpcap.pc,
# so that "pkg-config --libs --static" will report them (those libraries
# cannot be determined using the library's .pc file, as there is no such
# file, so it has to come from our .pc file. Initialized to an empty
# string.

# in which the libpcap shared library is installed, and the install
# prefix /usr (meaning we're not installing a system library), provide
# the rpath option.
#
# (We must check $prefix, as $libdir isn't necessarily /usr/lib in this
# case - for example, Linux distributions for 64-bit platforms that
# also provide support for binaries for a 32-bit version of the
# platform may put the 64-bit libraries, the 32-bit libraries, or both
# in directories other than /usr/lib.)
#
# In AIX, do we have to do this?
#
# In Darwin-based OSes, the full paths of the shared libraries with
# which the program was linked are stored in the executable, so we don't
# need to provide an rpath option.
#
# With the HP-UX linker, directories specified with -L are, by default,
# added to the run-time search path, so we don't need to supply them.
#
# For Tru64 UNIX, "-rpath" works with DEC's^WCompaq's^WHP's C compiler
# for Alpha, but isn't documented as working with GCC, and no GCC-
# compatible option is documented as working with the DEC compiler.
# If anybody needs this on Tru64/Alpha, they're welcome to figure out a
# way to make it work.

# a GCC-compatible compiler and a vendor compiler, we need to work with
# both.
