21 * \brief User-configurable settings
23 * Miscellaneous switches:
25 * A number of macros affect a variety of minor aspects of ICU.
26 * Most of them used to be defined elsewhere (e.g., in utypes.h or platform.h)
27 * and moved here to make them easier to find.
29 * Switches for excluding parts of ICU library code modules:
31 * Changing these macros allows building partial, smaller libraries for special purposes.
32 * By default, all modules are built.
33 * The switches are fairly coarse, controlling large modules.
34 * Basic services cannot be turned off.
36 * Building with any of these options does not guarantee that the
37 * ICU build process will completely work. It is recommended that
38 * the ICU libraries and data be built using the normal build.
39 * At that time you should remove the data used by those services.
40 * After building the ICU data library, you should rebuild the ICU
41 * libraries with these switches customized to your needs.
47 * If this switch is defined, ICU will attempt to load a header file named "uconfig_local.h"
48 * prior to determining default settings for uconfig variables.
52 #if defined(UCONFIG_USE_LOCAL)
53 #include "uconfig_local.h"
58 * Determines whether to include debugging code.
59 * Automatically set on Windows, but most compilers do not have
60 * related predefined macros.
64 /* Use the predefined value. */
67 * _DEBUG is defined by Visual Studio debug compilation.
68 * Do *not* test for its NDEBUG macro: It is an orthogonal macro
69 * which disables assert().
77 * Determines wheter to enable auto cleanup of libraries.
80 #ifndef UCLN_NO_AUTO_CLEANUP
81 #define UCLN_NO_AUTO_CLEANUP 1
85 * \def U_DISABLE_RENAMING
86 * Determines whether to disable renaming or not.
89 #ifndef U_DISABLE_RENAMING
90 #define U_DISABLE_RENAMING 0
94 * \def U_NO_DEFAULT_INCLUDE_UTF_HEADERS
95 * Determines whether utypes.h includes utf.h, utf8.h, utf16.h and utf_old.h.
96 * utypes.h includes those headers if this macro is defined to 0.
97 * Otherwise, each those headers must be included explicitly when using one of their macros.
98 * Defaults to 0 for backward compatibility, except inside ICU.

112 * \def U_OVERRIDE_CXX_ALLOCATION
113 * Determines whether to override new and delete.
114 * ICU is normally built such that all of its C++ classes, via their UMemory base,
115 * override operators new and delete to use its internal, customizable,
116 * non-exception-throwing memory allocation functions. (Default value 1 for this macro.)
118 * This is especially important when the application and its libraries use multiple heaps.
119 * For example, on Windows, this allows the ICU DLL to be used by
120 * applications that statically link the C Runtime library.

200 * for ICU to work on EBCDIC platforms (for the default converter).

231 * equivalent way to link to the data residing in an executable,
232 * as in building a combined library with both the common library's code and
233 * the data), or via udata_setCommonData().
234 * Application data must be provided via udata_setAppData() or by using
235 * "open" functions that take pointers to data, for example ucol_openBinary().
237 * File access is not used at all in the i18n library.
