GENCCODE(8)                 ICU 76.0.1 Manual                 GENCCODE(8)

NAME top

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

SYNOPSIS top

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

DESCRIPTION top

       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 top

       -h, -?, --help
              Print help about usage and exit.

       -a, --assembly name
              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
              Set the destination directory to destination.  The default
              destination directory is the current directory.

       -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).

       -f, --filename name
              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
              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).
