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.
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).
Specifies the directory containing ICU data. Defaults to /usr/share/icu/57.1/. 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.
