GENCMN(8)			ICU 76.1 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 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
       -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  des-
	      tination	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  op-
	      tion).

ENVIRONMENT
       ICU_DATA	 Specifies  the	 directory  containing	ICU  data. Defaults to
		 ${prefix}/share/icu/76.1/.  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.

VERSION
       76.1
