|
|
* \brief Switches for excluding parts of ICU library code modules.
|
|
*
|
|
* Allows to build partial, smaller libraries for special purposes.
|
|
* By default, all modules are built.
|
|
* The switches are fairly coarse, controlling large modules.
|
|
* Basic services cannot be turned off.
|
|
*
|
|
* Building with any of these options does not guarantee that the
|
|
* ICU build process will completely work. It is recommended that
|
|
* the ICU libraries and data be built using the normal build.
|
|
* At that time you should remove the data used by those services.
|
|
* After building the ICU data library, you should rebuild the ICU
|
|
* libraries with these switches customized to your needs.
|
|
*
|

* @stable ICU 2.4

/**
|
|
* \def UCONFIG_ONLY_COLLATION
|
|
* This switch turns off modules that are not needed for collation.
|
|
*
|
|
* It does not turn off legacy conversion because that is necessary
|
|
* for ICU to work on EBCDIC platforms (for the default converter).
|
|
* If you want "only collation" and do not build for EBCDIC,
|
|
* then you can define UCONFIG_NO_LEGACY_CONVERSION 1 as well.
