56 // 22 Jul 99 Initial version
59 #ifndef BOOST_CONFIG_HPP
60 #define BOOST_CONFIG_HPP
62 #define BOOST_VERSION 102200
64 // BOOST_VERSION % 100 is the sub-minor version
65 // BOOST_VERSION / 100 % 1000 is the minor version
66 // BOOST_VERSION / 100000 is the major version
69 // Conformance Flag Macros -------------------------------------------------//
71 // Conformance flag macros should identify the absence of C++ Standard
72 // conformance rather than its presence. This ensures that standard conforming
73 // compilers do not require a lot of configuration flag macros. It places the
74 // burden where it should be, on non-conforming compilers. In the future,
75 // hopefully, less rather than more conformance flags will have to be defined.
77 // BOOST_NO_CV_SPECIALIZATIONS: if template specialisations for cv-qualified types
78 // conflict with a specialistaion for unqualififed type.
80 // BOOST_NO_CV_VOID_SPECIALIZATIONS: if template specialisations for cv-void types
81 // conflict with a specialistaion for void.
83 // BOOST_NO_ARGUMENT_DEPENDENT_LOOKUP: Compiler does not implement
84 // argument-dependent lookup (also named Koenig lookup); see std::3.4.2
85 // [basic.koenig.lookup]
87 // BOOST_NO_DEPENDENT_TYPES_IN_TEMPLATE_VALUE_PARAMETERS: Template value
88 // parameters cannot have a dependent type, for example
89 // "template<class T, typename T::type value> class X { ... };"
91 // BOOST_NO_EXPLICIT_FUNCTION_TEMPLATE_ARGUMENTS: Can only use deduced
92 // template arguments when calling function template instantiations.
94 // BOOST_NO_INCLASS_MEMBER_INITIALIZATION: Compiler violates std::9.4.2/4.
96 // BOOST_NO_INT64_T: <boost/cstdint.hpp> does not support 64-bit integer
97 // types. (Set by <boost/cstdint.hpp> rather than <boost/config.hpp>).
99 // BOOST_NO_INTEGRAL_INT64_T: int64_t as defined by <boost/cstdint.hpp> is
100 // not an integral type.
102 // BOOST_NO_LIMITS_COMPILE_TIME_CONSTANTS: constants such as
103 // numeric_limits<T>::is_signed are not available for use at compile-time.
105 // BOOST_NO_MEMBER_TEMPLATES: Member template functions not fully supported.
106 // Also see BOOST_MSVC6_MEMBER_TEMPLATES in the Compiler Control section below.
108 // BOOST_NO_MEMBER_TEMPLATE_FRIENDS: Member template friend syntax
109 // ("template<class P> friend class frd;") described in the C++ Standard,
110 // 14.5.3, not supported.
112 // BOOST_NO_OPERATORS_IN_NAMESPACE: Compiler requires inherited operator
113 // friend functions to be defined at namespace scope, then using'ed to boost.
114 // Probably GCC specific. See boost/operators.hpp for example.
116 // BOOST_NO_POINTER_TO_MEMBER_CONST: The compiler does not correctly handle
117 // pointers to const member functions, preventing use of these in overloaded
118 // function templates. See boost/functional.hpp for example.
120 // BOOST_NO_PRIVATE_IN_AGGREGATE: The compiler misreads 8.5.1, treating classes
121 // as non-aggregate if they contain private or protected member functions.
123 // BOOST_NO_STD_ITERATOR: The C++ implementation fails to provide the
124 // std::iterator class.
126 // BOOST_NO_STD_ITERATOR_TRAITS: The compiler does not provide a standard
127 // compliant implementation of std::iterator_traits. Note that
128 // the compiler may still have a non-standard implementation.
130 // BOOST_NO_STDC_NAMESPACE: The contents of C++ standard headers for C library
131 // functions (the <c...> headers) have not been placed in namespace std.
132 // Because the use of std::size_t is so common, a specific workaround for
133 // <cstddef> (and thus std::size_t) is provided in this header (see below).
134 // For other <c...> headers, a workaround must be provided in the boost header:
136 // #include <cstdlib> // for abs
137 // #ifdef BOOST_NO_STDC_NAMESPACE
138 // namespace std { using ::abs; }
141 // BOOST_NO_TEMPLATE_PARTIAL_SPECIALIZATION. Class template partial
142 // specialization (14.5.4 [temp.class.spec]) not supported.
144 // BOOST_NO_USING_TEMPLATE: The compiler will not accept a using declaration
145 // that imports a template from the global namespace into a named namespace.
146 // Probably Borland specific.
148 // BOOST_NO_AUTO_PTR: If the compiler / library supplies non-standard or broken
151 // Compiler Control or Information Macros ----------------------------------//
153 // Compilers often supply features outside of the C++ Standard which need to be
154 // controlled or detected. As usual, reasonable default behavior should occur
155 // if any of these macros are not defined.
157 // BOOST_DECL: Certain compilers for Microsoft operating systems require
158 // non-standard class and function decoration if dynamic load library linking
159 // is desired. BOOST_DECL supplies that decoration. Boost does not require
160 // use of BOOST_DECL - it is non-standard and to be avoided if practical to do
161 // so. Even compilers requiring it for DLL's only require it in certain cases.
163 // BOOST_DECL_EXPORTS: User defined, usually via command line or IDE,
164 // it causes BOOST_DECL to be defined as __declspec(dllexport).
166 // BOOST_DECL_IMPORTS: User defined, usually via command line or IDE,
167 // it causes BOOST_DECL to be defined as __declspec(dllimport).
169 // If neither BOOST_DECL_EXPORTS nor BOOST_DECL_IMPORTS is defined, or if
170 // the compiler does not require __declspec() decoration, BOOST_DECL is
171 // defined as a null string.
173 // BOOST_MSVC6_MEMBER_TEMPLATES: Microsoft Visual C++ 6.0 has enough member
174 // template idiosyncrasies (being polite) that BOOST_NO_MEMBER_TEMPLATES is
175 // defined for this compiler. BOOST_MSVC6_MEMBER_TEMPLATES is defined to allow
176 // compiler specific workarounds.
178 // BOOST_MSVC: defined as _MSC_VER for the Microsoft compiler only. In general,
179 // boost headers should test for a specific conformance flag macro (for
180 // example, BOOST_NO_MEMBER_TEMPLATE_FRIENDS) rather than a specific compiler.
181 // VC++ is a special case, however, since many libraries try to support it yet
182 // it has so many conformance issues that sometimes it is just easier to test
183 // for it directly. On the other hand, the obvious way to do this doesn't work,
184 // as many non-Microsoft compilers define _MSC_VER. Thus BOOST_MSVC.
186 // BOOST_MSVC_STD_ITERATOR: Microsoft's broken version of std::iterator
189 // BOOST_SYSTEM_HAS_STDINT_H: There are no 1998 C++ Standard headers <stdint.h>
190 // or <cstdint>, although the 1999 C Standard does include <stdint.h>.
191 // If <stdint.h> is present, <boost/stdint.h> can make good use of it,
192 // so a flag is supplied (signalling presence; thus the default is not
193 // present, conforming to the current C++ standard).
195 // BOOST_NO_SLIST: The C++ implementation does not provide the slist class.
197 // BOOST_NO_STRINGSTREAM: The C++ implementation does not provide the <sstream> header.
199 // BOOST_NO_HASH: The C++ implementation does not provide the hash_set
200 // or hash_map classes.
202 // BOOST_STD_EXTENSION_NAMESPACE: The name of the namespace in which the slist,
203 // hash_set and/or hash_map templates are defined in this implementation (if any).
205 // BOOST_NO_TEMPLATED_ITERATOR_CONSTRUCTORS: The standard library does not provide
206 // templated iterator constructors for its containers.
208 // BOOST_NO_LIMITS: The C++ implementation does not provide the <limits> header.
210 // BOOST_NO_INTRINSIC_WCHAR_T: The C++ implementation does not provide wchar_t,
211 // or it is really a synonym for another integral type. Use this symbol to
212 // decide whether it is appropriate to explicitly specialize a template on
213 // wchar_t if there is already a specialization for other integer types.
215 // BOOST_NO_STD_ALLOCATOR: The C++ standard library does not provide
216 // a standards conforming std::allocator.
218 // BOOST_NO_STD_MIN_MAX: The C++ standard library does not provide
219 // the min() and max() template functions that should be in <algorithm>.
