Introduce EXTRA_VERSION_NAME and EXTRA_VERSION_DESCRIPTION
[lttng-tools.git] / include / Makefile.am
1 ##
2 ## This target generates an include file that contains the git version
3 ## string of the current branch, it must be continuously updated when
4 ## we build in the git repo and shipped in dist tarballs to reflect the
5 ## status of the tree when it was generated. If the tree is clean and
6 ## the current commit is tag a starting with "v", consider this a
7 ## release version and set an empty git version.
8 ##
9 ## Here is what the inline script does:
10 ##
11 ## First, delete any stale "version.i.tmp" file.
12 ##
13 ## If "bootstrap" and ".git" exists in the top source directory and the git
14 ## executable is available, get the current git version string in the form:
15 ##
16 ## "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty)
17 ##
18 ## And store it in "version.i.tmp", if the current commit is tagged, the tag
19 ## starts with "v" and the tree is clean, consider this a release version and
20 ## overwrite the git version with an empty string in "version.i.tmp".
21 ##
22 ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty
23 ## string as a failover. If a "version.i" is present, for example when building
24 ## from a distribution tarball, get the git_version using grep.
25 ##
26 ## Fetch the EXTRA_VERSION_NAME define from "version/extra_version_name" and output it
27 ## to "version.i.tmp".
28 ##
29 ## Fetch the EXTRA_VERSION_DESCRIPTION define from "version/extra_version_description",
30 ## sanitize and format it with a sed script to replace all non-alpha-numeric values
31 ## with "-" and join all lines by replacing "\n" with litteral string c-style "\n\t" and
32 ## output it to "version.i.tmp".
33 ##
34 ## If we don't have a "version.i" or we have both files (version.i, version.i.tmp)
35 ## and they are different, copy "version.i.tmp" over "version.i".
36 ## This way the dependent targets are only rebuilt when the git version
37 ## string or either one of extra version string change.
