Subject: Add a --with-consumerd-only configure option
X-Git-Tag: v2.0-pre15~56
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=55bed2138489dd1bfc43726e0ce71f7d5ee6d62c;p=lttng-tools.git

Add a --with-consumerd-only configure option

This will only build the consumer daemon (and its liblttng-consumer
library), and skip the lttng and lttng-sessiond binaries.

This will be useful when a user wants to support both 32-bit and
64-bit applications on the same system. Only one sessiond is
needed, but we need a consumer for each architecture.
