Click FreeImage.2017.sln solution

Dynamic Library compilation Click to generate Engineering FreeImage

Note: the precompiler adds the precompiled definition FREEIMAGE_EXPORTS to export the function.

Static library compilation Click to generate Engineering FreeImageLib

Note: pre-compiled definition FREEIMAGE_LIB is added to the precompiler + precompiler.

The output file is saved in Dist/x32

The macro definition compilation details of the header file are as follows:

# if defined (FREEIMAGE_LIB)

# define DLL_API

# define DLL_CALLCONV

# else

# if defined (_ WIN32) | | defined (_ _ WIN32__)

# define DLL_CALLCONV _ _ stdcall

/ / The following ifdef block is the standard way of creating macros which make exporting

/ / from a DLL simpler. All files within this DLL are compiled with the FREEIMAGE_EXPORTS

/ / symbol defined on the command line. This symbol should not be defined on any project

/ / that uses this DLL. This way any other project whose source files include this file see

/ / DLL_API functions as being imported from a DLL, wheras this DLL sees symbols

/ / defined with this macro as being exported.

# ifdef FREEIMAGE_EXPORTS

# define DLL_API _ _ declspec (dllexport)

# else

# define DLL_API _ _ declspec (dllimport)

# endif / / FREEIMAGE_EXPORTS

# else

/ / try the gcc visibility support (see http://gcc.gnu.org/wiki/Visibility)

# if defined (_ _ GNUC__) & & ((_ _ GNUC__ > = 4) | | (_ _ GNUC__ = = 3 & & _ _ GNUC_MINOR__ > = 4))

# ifndef GCC_HASCLASSVISIBILITY

# define GCC_HASCLASSVISIBILITY

# endif

# endif / / _ _ GNUC__

# define DLL_CALLCONV

# if defined (GCC_HASCLASSVISIBILITY)

# define DLL_API _ attribute__ ((visibility ("default")

# else
