FreeType

[Rayven]

I am compiling an application using the FreeType libraries that are included with Qt. I am using VisualStudios 2005 and 2003 with Qt4.1.0. Both environments give the same error when compiling:

1>.\src\BitmapFace.cpp(33) : error C2061: syntax error : identifier 'FT_New_Memory_Face'

I have all the include and library paths for FreeType correct and no other error messages are given. This same source code compiles just fine under Solaris and Linux.

const FT_Long DEFAULT_FACE_INDEX = 0;
   ftFace = new FT_Face;
 
   err = new FT_New_Memory_Face( *BitmapLibrary::Instance( ).GetLibrary( ),
                                 (FT_Byte *)pBufferBytes,
                                 bufferSizeInBytes,
                                 DEFAULT_FACE_INDEX,
                                 ftFace );

const FT_Long DEFAULT_FACE_INDEX = 0;
   ftFace = new FT_Face;

   err = new FT_New_Memory_Face( *BitmapLibrary::Instance( ).GetLibrary( ),
                                 (FT_Byte *)pBufferBytes,
                                 bufferSizeInBytes,
                                 DEFAULT_FACE_INDEX,
                                 ftFace );

Could you look where FT_New_MemoRy_Face is implemented? Maybe it is conditionally defined...And you need to add that preprocessor definition.

Or on Win, you have to include something that on Linux gets included automatically. These things often hapen.

Disregard my last post

I believe this is the solution ( it's from the freetype2 tutorial ):

Include the main FreeType 2 API header file.
You should do that using the macro FT_FREETYPE_H, like in the following example:

#include <ft2build.h>
#include FT_FREETYPE_H

FT_FREETYPE_H is a special macro defined in the file ftheader.h. It contains some installation-specific macros to name other public header files of the FreeType 2 API.

FT_New_Memory_Face is defined in freetype.h as:

FT_EXPORT( FT_Error )
  FT_New_Memory_Face( FT_Library      library,
                      const FT_Byte*  file_base,
                      FT_Long         file_size,
                      FT_Long         face_index,
                      FT_Face        *aface );

FT_EXPORT( FT_Error )
  FT_New_Memory_Face( FT_Library      library,
                      const FT_Byte*  file_base,
                      FT_Long         file_size,
                      FT_Long         face_index,
                      FT_Face        *aface );

My source file has defined:

#include <ft2build.h>
#include FT_FREETYPE_H

#include <ft2build.h>
#include FT_FREETYPE_H

To copy to clipboard, switch view to plain text mode 

which the freetype.h file says needs to be included. I am really unsure what else would need to be included under windows since all the documentation only says to include these two things.

You made a mistake in your code:

You said:

err = new FT_New_Memory_Face( ... ).


FT_New_Memory_Face is not an object, therefore you can't instantiate it with new.
Please correct this and see if it works.

This is an example from the tutorial:

FT_Library  library;   /* handle to library     */   
FT_Face     face;      /* handle to face object */     
error = FT_Init_FreeType( &library );

FT_Library  library;   /* handle to library     */   
FT_Face     face;      /* handle to face object */     
error = FT_Init_FreeType( &library );

BTW: how did this worked on linux?

Holy carp!! That was it...Thanks OH so much Marcel!!

You're welcome.
