* This module contains \#defines and symbols for exporting function

|
* calls, and providing version information and compiled-in features.
|
|
*
|
|
* If you are compiling for Windows (with Visual Studio or MinGW for
|
|
* example) and will link to the static library (libFLAC++.lib) you
|
|
* should define FLAC__NO_DLL in your project to make sure the symbols
|
|
* are exported properly.

/** This \#define is used internally in libFLAC and its headers to make
|
|
* sure the correct symbols are exported when working with shared
|
|
* libraries. On Windows, this \#define is set to __declspec(dllexport)
|
|
* when compiling libFLAC into a library and to __declspec(dllimport)
|
|
* when the headers are used to link to that DLL. On non-Windows systems
|
|
* it is used to set symbol visibility.
|
|
*
|
|
* Because of this, the define FLAC__NO_DLL must be defined when linking
|
|
* to libFLAC statically or linking will fail.
|
|
*/
|
|
/* This has grown quite complicated. FLAC__NO_DLL is used by MSVC sln
|
|
* files and CMake, which build either static or shared. autotools can
|
|
* build static, shared or **both**. Therefore, DLL_EXPORT, which is set
|
|
* by libtool, must override FLAC__NO_DLL on building shared components
