55 // 22 Jul 99 Initial version
58 #ifndef BOOST_CONFIG_HPP
59 #define BOOST_CONFIG_HPP
61 #define BOOST_VERSION 102200
63 // BOOST_VERSION % 100 is the sub-minor version
64 // BOOST_VERSION / 100 % 1000 is the minor version
65 // BOOST_VERSION / 100000 is the major version
68 // Conformance Flag Macros -------------------------------------------------//
70 // Conformance flag macros should identify the absence of C++ Standard
71 // conformance rather than its presence. This ensures that standard conforming
72 // compilers do not require a lot of configuration flag macros. It places the
73 // burden where it should be, on non-conforming compilers. In the future,
74 // hopefully, less rather than more conformance flags will have to be defined.
76 // BOOST_NO_CV_SPECIALIZATIONS: if template specialisations for cv-qualified types
77 // conflict with a specialistaion for unqualififed type.
79 // BOOST_NO_CV_VOID_SPECIALIZATIONS: if template specialisations for cv-void types
80 // conflict with a specialistaion for void.
82 // BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP: Compiler does not implement
83 // argument-dependent lookup (also named Koenig lookup); see std::3.4.2
84 // [basic.koenig.lookup]
86 // BOOST_NO_DEPENDENT_TYPES_IN_TEMPLATE_VALUE_PARAMETERS: Template value
87 // parameters cannot have a dependent type, for example
88 // "template<class T, typename T::type value> class X { ... };"
90 // BOOST_NO_INCLASS_MEMBER_INITIALIZATION: Compiler violates std::9.4.2/4.
92 // BOOST_NO_INT64_T: <boost/cstdint.hpp> does not support 64-bit integer
93 // types. (Set by <boost/cstdint.hpp> rather than <boost/config.hpp>).
95 // BOOST_NO_INTEGRAL_INT64_T: int64_t as defined by <boost/cstdint.hpp> is
96 // not an integral type.
98 // BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS: constants such as
99 // numeric_limits<T>::is_signed are not available for use at compile-time.
101 // BOOST_NO_MEMBER_TEMPLATES: Member template functions not fully supported.
102 // Also see BOOST_MSVC6_MEMBER_TEMPLATES in the Compiler Control section below.
104 // BOOST_NO_MEMBER_TEMPLATE_FRIENDS: Member template friend syntax
105 // ("template<class P> friend class frd;") described in the C++ Standard,
106 // 14.5.3, not supported.
108 // BOOST_NO_OPERATORS_IN_NAMESPACE: Compiler requires inherited operator
109 // friend functions to be defined at namespace scope, then using'ed to boost.
110 // Probably GCC specific. See boost/operators.hpp for example.
112 // BOOST_NO_POINTER_TO_MEMBER_CONST: The compiler does not correctly handle
113 // pointers to const member functions, preventing use of these in overloaded
114 // function templates. See boost/functional.hpp for example.
116 // BOOST_NO_PRIVATE_IN_AGGREGATE: The compiler misreads 8.5.1, treating classes
117 // as non-aggregate if they contain private or protected member functions.
119 // BOOST_NO_STD_ITERATOR: The C++ implementation fails to provide the
120 // std::iterator class.
122 // BOOST_NO_STD_ITERATOR_TRAITS: The compiler does not provide a standard
123 // compliant implementation of std::iterator_traits. Note that
124 // the compiler may still have a non-standard implementation.
126 // BOOST_NO_STDC_NAMESPACE: The contents of C++ standard headers for C library
127 // functions (the <c...> headers) have not been placed in namespace std.
128 // Because the use of std::size_t is so common, a specific workaround for
129 // <cstddef> (and thus std::size_t) is provided in this header (see below).
130 // For other <c...> headers, a workaround must be provided in the boost header:
132 // #include <cstdlib> // for abs
133 // #ifdef BOOST_NO_STDC_NAMESPACE
134 // namespace std { using ::abs; }
137 // BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION. Class template partial
138 // specialization (14.5.4 [temp.class.spec]) not supported.
140 // BOOST_NO_USING_TEMPLATE: The compiler will not accept a using declaration
141 // that imports a template from the global namespace into a named namespace.
142 // Probably Borland specific.
144 // BOOST_NO_AUTO_PTR: If the compiler / library supplies non-standard or broken
147 // Compiler Control or Information Macros ----------------------------------//
149 // Compilers often supply features outside of the C++ Standard which need to be
150 // controlled or detected. As usual, reasonable default behavior should occur
151 // if any of these macros are not defined.
153 // BOOST_DECL: Certain compilers for Microsoft operating systems require
154 // non-standard class and function decoration if dynamic load library linking
155 // is desired. BOOST_DECL supplies that decoration. Boost does not require
156 // use of BOOST_DECL - it is non-standard and to be avoided if practical to do
157 // so. Even compilers requiring it for DLL's only require it in certain cases.
159 // BOOST_DECL_EXPORTS: User defined, usually via command line or IDE,
160 // it causes BOOST_DECL to be defined as __declspec(dllexport).
162 // BOOST_DECL_IMPORTS: User defined, usually via command line or IDE,
163 // it causes BOOST_DECL to be defined as __declspec(dllimport).
165 // If neither BOOST_DECL_EXPORTS nor BOOST_DECL_IMPORTS is defined, or if
166 // the compiler does not require __declspec() decoration, BOOST_DECL is
167 // defined as a null string.
169 // BOOST_MSVC6_MEMBER_TEMPLATES: Microsoft Visual C++ 6.0 has enough member
170 // template idiosyncrasies (being polite) that BOOST_NO_MEMBER_TEMPLATES is
171 // defined for this compiler. BOOST_MSVC6_MEMBER_TEMPLATES is defined to allow
172 // compiler specific workarounds.
174 // BOOST_MSVC: defined as _MSC_VER for the Microsoft compiler only. In general,
175 // boost headers should test for a specific conformance flag macro (for
176 // example, BOOST_NO_MEMBER_TEMPLATE_FRIENDS) rather than a specific compiler.
177 // VC++ is a special case, however, since many libraries try to support it yet
178 // it has so many conformance issues that sometimes it is just easier to test
179 // for it directly. On the other hand, the obvious way to do this doesn't work,
180 // as many non-Microsoft compilers define _MSC_VER. Thus BOOST_MSVC.
182 // BOOST_MSVC_STD_ITERATOR: Microsoft's broken version of std::iterator
185 // BOOST_SYSTEM_HAS_STDINT_H: There are no 1998 C++ Standard headers <stdint.h>
186 // or <cstdint>, although the 1999 C Standard does include <stdint.h>.
187 // If <stdint.h> is present, <boost/stdint.h> can make good use of it,
188 // so a flag is supplied (signalling presence; thus the default is not
189 // present, conforming to the current C++ standard).
191 // BOOST_NO_SLIST: The C++ implementation does not provide the slist class.
193 // BOOST_NO_STRINGSTREAM: The C++ implementation does not provide the <sstream> header.
195 // BOOST_NO_HASH: The C++ implementation does not provide the hash_set
196 // or hash_map classes.
198 // BOOST_STD_EXTENSION_NAMESPACE: The name of the namespace in which the slist,
199 // hash_set and/or hash_map templates are defined in this implementation (if any).
201 // BOOST_NO_TEMPLATED_ITERATOR_CONSTRUCTORS: The standard library does not provide
202 // templated iterator constructors for its containers.
204 // BOOST_NO_LIMITS: The C++ implementation does not provide the <limits> header.
206 // BOOST_NO_INTRINSIC_WCHAR_T: The C++ implementation does not provide wchar_t,
207 // or it is really a synonym for another integral type. Use this symbol to
208 // decide whether it is appropriate to explicitly specialize a template on
209 // wchar_t if there is already a specialization for other integer types.
211 // BOOST_NO_STD_ALLOCATOR: The C++ standard library does not provide
212 // a standards conforming std::allocator.
214 // BOOST_NO_STD_MIN_MAX: The C++ standard library does not provide
215 // the min() and max() template functions that should be in <algorithm>.
