From db39cc76982b8d5e4732c25e46774f988d3df377 Mon Sep 17 00:00:00 2001 From: Naushir Patuck Date: Mon, 18 Oct 2021 10:29:42 +0100 Subject: build: Preserve upstream git versioning using meson dist When distributions build and package libcamera libraries, they may not necessarily run the build in the upstream source tree. In these cases, the git SHA1 versioning information will be lost. This change addresses that problem by requiring package managers to run 'meson dist' to create a tarball of the source files and build from there. On runing 'meson dist', the utils/run-dist.sh script will create a .tarball-version file in the release tarball with the version string generated from the existing utils/gen-version.sh script. The utils/gen-version.sh script has been updated to check for the presence of this .tarball-version file and read the version string from it instead of creating one.
