[_GENCNVAL_(1)](https://www.chedong.com/phpMan.php/man/GENCNVAL/1/markdown)                                ICU 74.2 Manual                               [_GENCNVAL_(1)](https://www.chedong.com/phpMan.php/man/GENCNVAL/1/markdown)

## NAME
       **gencnval **- compile the converters aliases file

## SYNOPSIS
       **gencnval  **[ **-h**, **-?**, **--help **] [ **-v**, **--verbose **] [ **-c**, **--copyright **] [ **-s**, **--sourcedir _**source_ ]
       [ **-d**, **--destdir _**destination_ ] [ _converterfile_ ]

## DESCRIPTION
       **gencnval **converts the ICU aliases file _converterfile_ into the binary file **cnvalias.icu**.  This
       binary file can then be read directly by ICU, or used by [**pkgdata**(1)](https://www.chedong.com/phpMan.php/man/pkgdata/1/markdown) for incorporation into  a
       larger archive or library.

       If _converterfile_ is not provided, the default ICU **convrtrs.txt **file is used.

## OPTIONS
### -h -? --help
              Print help about usage and exit.

### -v --verbose
              Display  verbose  output.  This  information can include information about conflicting
              aliases and the converters the aliases resolve to.

### -c --copyright
              Include a copyright notice in the binary data.

### -s --sourcedir _
              Set the source directory to _source_.  The default source directory is specified by  the
              environment variable **ICU_DATA**.

### -d --destdir _
              Set  the  destination  directory to _destination_.  The default destination directory is
              specified by the environment variable **ICU_DATA**.

## ENVIRONMENT
       **ICU_DATA  **Specifies the directory containing ICU data. Defaults to **${prefix}/share/icu/74.2/**.
                 Some tools in ICU depend on the presence of the trailing slash. It is  thus  impor‐
                 tant to make sure that it is present if **ICU_DATA **is set.

## FILES
       **icu/source/data/mappings/convrtrs.txt   **Description  of  ICU's  converters and their aliases.
                                               This data file is not normally installed, and  it  is
                                               available as a part of ICU source code.
