GENCMN(8)                   ICU 76.0.1 Manual                   GENCMN(8)

NAME         top

       gencmn - generate an ICU memory-mappable data file

SYNOPSIS         top

       gencmn [ -h, -?, --help ] [ -v, --verbose ] [ -c, --copyright |
       -C, --comment comment ] [ -d, --destdir destination ] [ -n, --name
       name ] [ -t, --type fileext ] [ -S, --source ] [ -e, --entrypoint
       name ] maxsize [ listfilename ]

DESCRIPTION         top

       gencmn takes a set of files and packages them as an ICU memory-
       mappable data file. The resulting data file can then be used
       directly by ICU.

       gencmn reads a list of files to be packaged from either the
       supplied listfilename file, or from its standard output. It
       packages all the files from the list that are not bigger than
       maxsize bytes, except if maxsize is 0, which indicates that there
       is no size limit on files.

OPTIONS         top

       -h, -?, --help
              Print help about usage and exit.

       -v, --verbose
              Display extra informative messages during execution.

       -c,--copyright
              Include the ICU copyright notice in the resulting data.

       -C, --comment comment
              Include the specified comment in the resulting data instead
              of the ICU copyright notice.

       -d, --destdir destination
              Set the destination directory to destination.  The default
              destination directory is specified by the environment
              variable ICU_DATA.

       -n, --name name
              Set the data name to name instead of the default. This name
              is also used as the base name of the output. The default
              name is made of the icudt prefix, followed by a two-digit
              version number corresponding to the current version of the
              ICU release, and a single letter indicating the endianness
              of the data (the letter b indicated big endian data, and
              the letter l indicates little endian ones).

       -t, --type type
              Use type as the type of the data. This type is also used as
              the extension of the generated data file. The default type
              ie dat.

       -S, --source
              Write a C source file with the table of contents of the
              data.

       -e, --entrypoint name
              Set the data entry point (used for linking against the data
              in a shared library form) to name.  The default entry point
              name is made of the data (set by the -n, --name option)
              followed by an underscore and the type of the data (set by
              the -t, --type option).

ENVIRONMENT         top

       ICU_DATA
              Specifies the directory containing ICU data. Defaults to
              ${prefix}/share/icu/76.0.1/.  Some tools in ICU depend on
              the presence of the trailing slash. It is thus important to
              make sure that it is present if ICU_DATA is set.
