Detailed Description

Library configuration file.

config_dll.h provides defines for shared objects and dynamic libraries. Generally speaking the macros are used to export classes and template classes from the Win32 dynamic link library. When not building the Win32 dynamic link library they are mostly an extern template declaration.

In practice they are a furball coughed up by a cat and then peed on by a dog. They are awful to get just right because of inconsistent compiler support for extern templates, manual instantiation and the FIPS DLL.

config.h was split into components in May 2019 to better integrate with Autoconf and its feature tests. The splitting occurred so users could continue to include config.h while allowing Autoconf to write new config_asm.h and new config_cxx.h using its feature tests.

Note

You should include config.h rather than config_dll.h directly.
