<div class="textblock"><p>User-configurable settings. </p>
<p>Miscellaneous switches:</p>
<p>A number of macros affect a variety of minor aspects of ICU. Most of them used to be defined elsewhere (e.g., in <a class="el" href="utypes_8h.html" title="Basic definitions for ICU, for both C and C++ APIs. ">utypes.h</a> or <a class="el" href="platform_8h.html" title="Basic types for the platform. ">platform.h</a>) and moved here to make them easier to find.</p>
<p>Switches for excluding parts of ICU library code modules:</p>
<p>Changing these macros allows building 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.</p>
<p>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.</p>
