/** \file compiler.h
|
|
* A set of defines to encapsulate compiler and platform differences.
|
|
* Please refer to the source code for full documentation on this file.
|
|
*
|
|
* Here is a summary of what this file does.
|
|
*
|
|
* (1) Defines macros for some STL includes which may be affected
|
|
* by file name length limitations.
|
|
*
|
|
* (2) Defines macros for some features not supported by all C++ compilers.
|
|
*
|
|
* (3) Defines 'explicit' as a null macro if the compiler doesn't support
|
|
* the explicit keyword.
|
|
*
|
|
* (4) Defines 'typename' as a null macro if the compiler doesn't support
|
|
* the typename keyword.
|
|
*
|
|
* (5) Defines bool, true and false if the compiler doesn't do so.
|
|
*
|
|
* (6) Defines SG_EXPLICIT_FUNCTION_TMPL_ARGS if the compiler
|
|
* supports calling a function template by providing its template
|
|
* arguments explicitly.
|
|
*
|
|
* (7) Defines SG_NEED_AUTO_PTR if STL doesn't provide auto_ptr<>.
|
|
*
|
|
* (8) Defines SG_NO_ARROW_OPERATOR if the compiler is unable
|
|
* to support operator->() for iterators.
|
|
*
|
|
* (9) Defines SG_USE_EXCEPTIONS if the compiler supports exceptions.
|
|
* Note: no FlightGear code uses exceptions.
|
|
*
|
|
* (10) Define SG_NAMESPACES if the compiler supports namespaces.
|
|
*
|
|
* (11) SG_MATH_FN_IN_NAMESPACE_STD -- not used??
|
|
*
|
|
* (12) Define SG_HAVE_STD if std namespace is supported.
|
|
*
|
|
* (13) Defines SG_CLASS_PARTIAL_SPECIALIZATION if the compiler
|
|
* supports partial specialization of class templates.
|
|
*
|
|
* (14) Defines SG_HAVE_STD_INCLUDES to use ISO C++ Standard headers.
|
|
*
|
|
* (15) Defines SG_HAVE_STREAMBUF if <streambuf> of <streambuf.h> are present.
|
|
*
|
|
* (16) Define SG_MATH_EXCEPTION_CLASH if math.h defines an exception class
|
|
* that clashes with the one defined in <stdexcept>.
