GENCMN(8)                                  ICU 74.2 Manual                                 GENCMN(8)

NAME
       gencmn - generate an ICU memory-mappable data file

SYNOPSIS
       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
       gencmn takes a set of files and packages them as an ICU memory-mappable data  file.  The  re‐
       sulting 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
       -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 no‐
              tice.

       -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  gen‐
              erated 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  op‐
              tion)  followed  by  an underscore and the type of the data (set by the -t, --type op‐
              tion).

ENVIRONMENT
       ICU_DATA  Specifies the directory containing ICU data. Defaults to ${prefix}/share/icu/74.2/.
                 Some tools in ICU depend on the presence of the trailing slash. It is  thus  impor‐
                 tant to make sure that it is present if ICU_DATA is set.

VERSION
       74.2
