- switch to macro driven module build for multiple kernel versions

[packages/lttng-modules.git] / lttng-modules.spec

#
# Conditional build:
%bcond_without	dist_kernel	# allow non-distribution kernel
%bcond_without	allprobes	# all probes build (some probes, e.g. fs, need full kernel source)
%bcond_with	verbose		# verbose build (V=1)

# The goal here is to have main, userspace, package built once with
# simple release number, and only rebuild kernel packages with kernel
# version as part of release number, without the need to bump release
# with every kernel change.
