21 | ## This target generates an include file that contains the git version | |
22 | ## string of the current branch, it must be continuously updated when | |
23 | ## we build in the git repo and shipped in dist tarballs to reflect the | |
24 | ## status of the tree when it was generated. If the tree is clean and | |
25 | ## the current commit is tag a starting with "v", consider this a | |
26 | ## release version and set an empty git version. | |
27 | ## | |
28 | ## Here is what the inline script does: | |
29 | ## | |
30 | ## First, delete any stale "version.i.tmp" file. | |
31 | ## | |
32 | ## If "bootstrap" and ".git" exists in the top source directory and the git | |
33 | ## executable is available, get the current git version string in the form: | |
34 | ## | |
35 | ## "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty) | |
36 | ## | |
37 | ## And store it in "version.i.tmp", if the current commit is tagged, the tag | |
38 | ## starts with "v" and the tree is clean, consider this a release version and | |
39 | ## overwrite the git version with an empty string in "version.i.tmp". | |
40 | ## | |
41 | ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty | |
42 | ## string as a failover. | |
43 | ## | |
44 | ## If we don't have a "version.i" or we have both files and they are different, | |
45 | ## copy "version.i.tmp" over "version.i". This way the dependent targets are | |
46 | ## only rebuilt when the version string changes. | |
