6 /// \brief Library configuration file
7 /// \details <tt>config_dll.h</tt> provides defines for shared objects and
8 /// dynamic libraries. Generally speaking the macros are used to export
9 /// classes and template classes from the Win32 dynamic link library.
10 /// When not building the Win32 dynamic link library they are mostly an extern
11 /// template declaration.
12 /// \details In practice they are a furball coughed up by a cat and then peed
13 /// on by a dog. They are awful to get just right because of inconsistent
14 /// compiler support for extern templates, manual instantiation and the FIPS DLL.
15 /// \details <tt>config.h</tt> was split into components in May 2019 to better
16 /// integrate with Autoconf and its feature tests. The splitting occurred so
17 /// users could continue to include <tt>config.h</tt> while allowing Autoconf
18 /// to write new <tt>config_asm.h</tt> and new <tt>config_cxx.h</tt> using
19 /// its feature tests.
20 /// \note You should include <tt>config.h</tt> rather than <tt>config_dll.h</tt>
21 /// directly.
