# If DEB_BUILD_OPTIONS has "debug" in it, we want to pass
# --enable-debug to configure.
#
# We also want to build in a separate build directory:
# debian/build-tree, because it's just so much easier to ignore files
# in there.
#
# By the way, if one wants to pass extra flags to configure, that can
# be done with EXTRA_CONFIGURE_OPTS, we don't override it, only append
# to it.

# dh_makeshlibs wants to be clever and treat plugins as shared libs.
# Slap it in the face, and tell it not to. We also do not need any
# script modifications, as our single shared lib is in a private

# anything that build-depends on syslog-ng-dev, so lets make a correct
# shlibs file for that, shall we?

# Since syslog-ng depends on all the modules, and syslog-ng-core

# of syslog-ng come out, lets make our life easy, and provide a custom
# sng:Modules substvar, which has all the module packages listed. We
# also provide sng:CoreModules, which lists core modules that were
# part of syslog-ng (or it depended on them) previously, in 3.3.
