35 # Generate Gromacs development build version information.
37 # This script generates version information for a build from a development
38 # source tree based on git repository information.
39 # It is assumed that by default the script is run in cmake script mode.
40 # If *not* called in script mode but used in generating cache variables,
41 # GEN_VERSION_INFO_INTERNAL has to be set ON.
43 # The following variables have to be previously defined:
44 # GIT_EXECUTABLE - path to git binary (must be >=1.5.3)
45 # PROJECT_VERSION - hard-coded version string (generated info is appended)
46 # PROJECT_SOURCE_DIR - top level source directory (which has to be in git)
47 # VERSION_CMAKEIN - path to an input template file
48 # VERSION_OUT - path to the output file
51 # VERSION_OUT is configured from the input VERSION_CMAKEIN
52 # using the variables listed below.
54 # GMX_VERSION_STRING_FULL - version string
55 # GMX_VERSION_FULL_HASH - git hash of current local HEAD
56 # GMX_VERSION_CENTRAL_BASE_HASH - git hash of the first ancestor commit from the
57 # main Gromacs repository
59 # Szilard Pall (pszilard@cbr.su.se)
60 # Teemu Murtola (teemu.murtola@gmail.com)
62 # Check input variables.
