# the main python version (single)
PYVER=$(shell py3versions -vd)
# extra python versions to build if any (plural)
# To enable multiple pyversions:
#   Build-Depends: python3-all-dev vs python3-dev in d/control.
#PYVERS=$(filter-out ${PYVER},$(shell py3versions -vs))
# This does not (yet) work for different python versions, b/c each next install
# rule below overrides python module files installed by the previous install,
# so we end up with just the last module.  Also, the upstream build system has
# bugs building pyldns in a subdir.
# We can do a loop over $PYVERS in build target and run make _ldns.la in turn,
# with all python-related definitions taken directly from python$vers-config,
# removing ldns_wrapper.*o before each step, and saving resulting _ldns.la
# under a version-specific name.  But this is too ugly already. Upstream should
# grow up a real module description file like setup.py and whole thing will be
# built automatically from there instead of using all the wrong custom
# commands, and it will automatically build things for multiple versions too,
# so we'll no need to override many targets in there.
# For now, build only for a single pyversion is supported.
