GENCMN(8) ICU 76.0.1 Manual GENCMN(8)
gencmn - generate an ICU memory-mappable data file
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 ]
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.
-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).
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.
