Subject: Fix: Make version.h generation work with dash
X-Git-Tag: v2.9.7~11
X-Git-Url: https://git.lttng.org./?a=commitdiff_plain;h=caee9faac16a11c9415d8fab99cef17da18e9cc7;p=lttng-tools.git

Fix: Make version.h generation work with dash

version.h generation failed when using dash as shell:
Generating version.h... /bin/sh: 24: Syntax error: Missing '))'

dash does not handle the following construct:
git_describe="$((cd /path/to/lttng-tools/.; git describe) 2>/dev/null)"

Use backquotes instead.

The fix has been tested with dash and bash.
