## SPDX-License-Identifier: GPL-2.0-only ## ## This target generates an include file that contains the git version ## string of the current branch, it must be continuously updated when ## we build in the git repo and shipped in dist tarballs to reflect the ## status of the tree when it was generated. If the tree is clean and ## the current commit is tag a starting with "v", consider this a ## release version and set an empty git version. ## ## Here is what the inline script does: ## ## First, delete any stale "version.i.tmp" file. ## ## If "bootstrap" and ".git" exists in the top source directory and the git ## executable is available, get the current git version string in the form: ## ## "latest_tag"(-"number_of_commits_on_top")(-g"latest_commit_hash")(-dirty) ## ## And store it in "version.i.tmp", if the current commit is tagged, the tag ## starts with "v" and the tree is clean, consider this a release version and ## overwrite the git version with an empty string in "version.i.tmp". ## ## If we don't have a "version.i.tmp" nor a "version.i", generate an empty ## string as a failover. If a "version.i" is present, for example when building ## from a distribution tarball, get the git_version using grep. ## ## Fetch the EXTRA_VERSION_NAME define from "version/extra_version_name" and output it ## to "version.i.tmp". ## ## Fetch the EXTRA_VERSION_DESCRIPTION define from "version/extra_version_description", ## sanitize and format it with a sed script to replace all non-alpha-numeric values ## with "-" and join all lines by replacing "\n" with litteral string c-style "\n\t" and ## output it to "version.i.tmp". ## ## Repeat the same logic for the "version/extra_patches" directory. ## Data fetched from "version/extra_patches" must be sanitized and ## formatted. ## The data is fetched using "ls" with an ignore pattern for the README file. ## The sanitize step uses sed with a script to replace all ## non-alpha-numeric values, except " " (space), to "-". ## The formatting step uses sed with a script to join all lines ## by replacing "\n" with litteral string c-style "\n\t". ## ## If we don't have a "version.i" or we have both files (version.i, version.i.tmp) ## and they are different, copy "version.i.tmp" over "version.i". ## This way the dependent targets are only rebuilt when the git version ## string or either one of extra version string change. ## version_verbose = $(version_verbose_@AM_V@) version_verbose_ = $(version_verbose_@AM_DEFAULT_V@) version_verbose_0 = @echo " GEN " $@; version.i: $(version_verbose)rm -f version.i.tmp; \ if (test !
