35 # Generate GROMACS release build version information, as well as build
36 # directory integrity checking.
38 # This script generates version information for a build from a release tarball
39 # source tree based on the release information in the released tarball.
40 # It is assumed that by default the script is run in cmake script mode.
41 # If *not* called in script mode but used in generating cache variables,
42 # GEN_VERSION_INFO_INTERNAL has to be set ON.
44 # The following variables have to be previously defined:
45 # PROJECT_VERSION - hard-coded version string (generated info is appended)
46 # PROJECT_SOURCE_DIR - top level source directory
47 # DIRECTORIES_TO_CHECKSUM - List of directories to hash
48 # VERSION_CMAKEIN - path to an input template file
49 # VERSION_OUT - path to the output file
51 # The following a possible additional definitions
52 # PYTHON_EXECUTABLE - Needed to run checking stage of current tree
53 # VERSION_STRING_OF_FORK - Possibly defined custom version string to override
54 # process of checking source file hashes.
56 # VERSION_OUT is configured from the input VERSION_CMAKEIN
57 # using the variables listed below.
59 # GMX_VERSION_STRING_FULL - version string
60 # GMX_RELEASE_SOURCE_FILE_CHECKSUM - Sha256 hash of source tree files at release
61 # GMX_CURRENT_SOURCE_FILE_CHECKSUM - Sha256 hash of current source tree files
