## NOTES: on how syslog-ng is linked
#
# There are two major linking modes currently:
# 1) dynamic: all libraries are linked dynamically, and assumed to be available as dynamic libraries
#
# 2) mixed: typical system provided libraries are linked dynamicaly, the
# rest is linked statically (Glib etc). Please note that _only_ the
# main syslog-ng executable is linked this way so that it can be
# started early during startup, tools and unit tests are linked
# dynamically the same way.
#
# The following variables are introduced and AC_SUBSTed to be used in Makefiles:
#
# SYSLOGNG_DEPS_LIBS:
# includes all dependendent libraries used by binary that can be linked in mixed mode (e.g. only the syslog-ng binary).
#
# TOOL_DEPS_LIBS:
# executables (e.g. tools & unit test programs) that link against
# libsyslog-ng.so should be linked with this set of libraries. other
# tools that do not use libsyslog-ng.so can use the _LIBS variables
# directly.
#
# CORE_DEPS_LIBS:
# libsyslog-ng.so is linked with this set of libraries.
#
# MODULE_DEPS_LIBS:
# The set of libraries that modules should be linked against. Only to
# satisfy their "core" dependency, any other libs that the core doesn't
# depend on must be linked explicitly.
#
# MODULE_LDFLAGS:
# The LDFLAGS to be passed when linking modules (may not contain
# library references -l and such, only linker flags)
#
# Modules should be linked against libsyslog-ng.la and libraries that are
# _NOT_ linked into libsyslog-ng.la no need to define a LIBS variable for
# that.

MODULE_LDFLAGS="-avoid-version -module -no-undefined"
