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.

This switch turns off all file access in the common library where file access is only used for data loading. ICU data must then be provided in the form of a data DLL (or with an equivalent way to link to the data residing in an executable, as in building a combined library with both the common library's code and the data), or via udata_setCommonData(). Application data must be provided via udata_setAppData() or by using "open" functions that take pointers to data, for example ucol_openBinary(). File access is not used at all in the i18n library. File access cannot be turned off for the icuio library or for the ICU test suites and ICU tools.

This switch turns off normalization. It implies turning off several other services as well, for example collation and IDNA.

This switch turns off regular expressions.

This switch turns off service registration.

This switch turns off transliteration.

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.
