GENCCODE(8) ICU 78.3 Manual GENCCODE(8)

# [NAME](#NAME)

**genccode** - generate C or platform specific assembly code from an ICU data file.

# [SYNOPSIS](#SYNOPSIS)

**genccode** \[ **-h, -?, --help** **]** **\[** **-a, --assembly **name**** **]** **\[** **-d, --destdir **destination**** **]** **\[** **-n, --name **name**** **]** **\[** **-e, --entrypoint **name**** **]** **\[** **-f, --filename **name**** **]** **\[** *filename* ... ]

# [DESCRIPTION](#DESCRIPTION)

**genccode** reads each of the supplied *filename* and writes out a C file containing a compilable definition of the data in the data file. The C file name is made by taking the base name of the data *filename*, replacing dots by underscores, and adding a *.c* file extension.

If the **-a** option is used, platform specific assembly code is generated instead of C code. Most C compilers will accept both C and assembly files. Instead of writing a filename with a *.c* file extension, a filename with a *.s* will be written instead.

If **genccode** is called with no *filename* it terminates gracefully.

# [OPTIONS](#OPTIONS)

[**-h, -?, --help**](#h)

Print help about usage and exit.

[**-a, --assembly **name****](#a)

Output assembly code instead of C code. Use **-h** to see the list of available types of assembly to generate and to specify for this option.

[**-d, --destdir **destination****](#d)

Set the destination directory to *destination*. The default destination directory is the current directory.

[**-n, --name **name****](#n)

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).

[**-f, --filename **name****](#f)

Normally, an ICU data file such as mydata.icu will be turned into mydata\_icu.c and mydata\_icu.o. However, if this parameter was set to "somedata", the output files will be somedata.o and somedata.c, respectively.

[**-e, --entrypoint **name****](#e)

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).**
