# Configure the source for building.
#
# Avahi uses and, in fact, requires pkg-config to set-up LDFLAGS and
# CFLAGS for LIBDAEMON even though these are explicitly provided on
# the configure command line above as prescribed in the "how to
# configure WITHOUT pkg-config" instructions.
#
# Unfortunately, some site Linux systems are quite old and have a
# version of pkg-config that avahi refuses to work with.
# Consequently, we place $(HostBinDir) first in the path to ensure
# that the project-local version of pkg-config is detected and used
# rather than a host- or site-local version.

# Stage the build to a temporary installation area.
#
# We have to unset MAKEFLAGS since they confuse the package build otherwise.
#
# We explictly remove 'libavahi-core.la' and 'libavahi-common.la'
# because some packages that depend on these libraries use libtool. If
# libtool finds a '*.la' file for a library, it uses the value of
# 'libdir=<dir>' it finds. In our case, since '--prefix=/usr' this
# value is '/usr/lib'. It then resolves '-lavahi-core' or
# '-lavahi-common' to '/usr/lib/libavahi-core.so' and
# '/usr/lib/libavahi-common.so', respectively. In a cross-compilation
# environment, this is likely to be neither the right architecture nor
# the right version to link against. In short, we lose.
#
# We could also handle this by removing DESTDIR and setting the prefix
# to $(ResultDirectory); however, that results in libtool hard-coding
# $(ResultDirectory) as the RPATH in the linked executables which is
# NOT what we want either. We lose again.
#
# By removing the '*.la' file, we win by ensuring neither a misdirected
# link nor an RPATH.
