16 * DESCRIPTION: regex extended config setup.
19 #ifndef BOOST_REGEX_CONFIG_HPP
20 #define BOOST_REGEX_CONFIG_HPP
22 * Borland C++ Fix/error check
23 * this has to go *before* we include any std lib headers:
25 #if defined(__BORLANDC__)
26 # include <boost/regex/config/borland.hpp>
29 /*****************************************************************************
31 * Include all the headers we need here:

37 # ifndef BOOST_REGEX_USER_CONFIG
38 # define BOOST_REGEX_USER_CONFIG <boost/regex/user.hpp>
41 # include BOOST_REGEX_USER_CONFIG
43 # include <boost/config.hpp>
48 * don't include <boost/config.hpp> because that may
49 * do C++ specific things in future...
54 # define BOOST_MSVC _MSC_VER
58 /*****************************************************************************

64 /* Obsolete macro, use BOOST_VERSION instead: */
65 #define BOOST_RE_VERSION 320
68 #if defined(_UNICODE) && !defined(UNICODE)
73 * Fix for gcc prior to 3.4: std::ctype<wchar_t> doesn't allow
74 * masks to be combined, for example:
75 * std::use_facet<std::ctype<wchar_t> >.is(std::ctype_base::lower|std::ctype_base::upper, L'a');
79 # define BOOST_REGEX_BUGGY_CTYPE_FACET
83 * Intel C++ before 8.0 ends up with unresolved externals unless we turn off
84 * extern template support:
86 #if defined(BOOST_INTEL) && defined(__cplusplus) && (BOOST_INTEL <= 800)
87 # define BOOST_REGEX_NO_EXTERNAL_TEMPLATES
90 * Visual C++ doesn't support external templates with C++ extensions turned off:
92 #if defined(_MSC_VER) && !defined(_MSC_EXTENSIONS)
93 # define BOOST_REGEX_NO_EXTERNAL_TEMPLATES
96 * Shared regex lib will crash without this, frankly it looks a lot like a gcc bug:
98 #if defined(__MINGW32__)
99 # define BOOST_REGEX_NO_EXTERNAL_TEMPLATES
103 * If there isn't good enough wide character support then there will
104 * be no wide character regular expressions:
106 #if (defined(BOOST_NO_CWCHAR) || defined(BOOST_NO_CWCTYPE) || defined(BOOST_NO_STD_WSTRING))
107 # if !defined(BOOST_NO_WREGEX)
108 # define BOOST_NO_WREGEX
111 # if defined(__sgi) && (defined(__SGI_STL_PORT) || defined(_STLPORT_VERSION))
112 /* STLPort on IRIX is misconfigured: <cwctype> does not compile
113 * as a temporary fix include <wctype.h> instead and prevent inclusion
114 * of STLPort version of <cwctype> */
116 # define __STLPORT_CWCTYPE
117 # define _STLP_CWCTYPE
121 # include <boost/regex/config/cwchar.hpp>
127 * If Win32 support has been disabled for boost in general, then
128 * it is for regex in particular:
130 #if defined(BOOST_DISABLE_WIN32) && !defined(BOOST_REGEX_NO_W32)
131 # define BOOST_REGEX_NO_W32
134 /* disable our own file-iterators and mapfiles if we can't
136 #if !defined(BOOST_HAS_DIRENT_H) && !(defined(_WIN32) && !defined(BOOST_REGEX_NO_W32))
137 # define BOOST_REGEX_NO_FILEITER
140 /* backwards compatibitity: */
141 #if defined(BOOST_RE_NO_LIB)
142 # define BOOST_REGEX_NO_LIB
145 #if defined(__GNUC__) && (defined(_WIN32) || defined(__CYGWIN__))
146 /* gcc on win32 has problems if you include <windows.h>
147 (sporadically generates bad code). */

161 * define BOOST_REGEX_HAS_OTHER_WCHAR_T when wchar_t is a native type, but the users
162 * code may be built with wchar_t as unsigned short: basically when we're building
163 * with MSVC and the /Zc:wchar_t option we place some extra unsigned short versions
164 * of the non-inline functions in the library, so that users can still link to the lib,
165 * irrespective of whether their own code is built with /Zc:wchar_t.
166 * Note that this does NOT WORK with VC10 when the C++ locale is in effect as
167 * the locale's <unsigned short> facets simply do not compile in that case.
