-Compiling FreeType 2 with PureC compiler

-========================================

-

-[See below for a German version.]

-

-To compile FreeType 2 as a library the following changes must be applied:

-

-- All *.c files must start with an uppercase letter.

-  (In case GEMSCRIPT is available:

-  Simply drag the whole FreeType 2 directory to the file `FNames.SIC'.)

-

-- You have to change the INCLUDE directory in PureC's compiler options

-  to contain both the `INCLUDE' and `freetype2\include' directory.

-  Example:

-

-    INCLUDE;E:\freetype2\include

-

-- The file `freetype2/include/Ft2build.h' must be patched as follows to

-  include ATARI.H:

-

-    #ifndef __FT2_BUILD_GENERIC_H__

-    #define __FT2_BUILD_GENERIC_H__

-

-    #include "ATARI.H"

-

-

-

-Compilieren von FreeType 2 mit PureC

-====================================

-

-Um FreeType 2 als eine Bibliothek (library) zu compilieren, muss folgendes

-ge„ndert werden:

-

-- Alle *.c-files m�ssen mit einem GROSSBUCHSTABEN beginnen.

-  (Falls GEMSCRIPT zur Verf�gung steht:

-  Den kompletten Ordner freetype2 auf die Datei `FNames.SIC' draggen.)

-

-- In den Compiler-Optionen von PureC muss das INCLUDE directory auf INCLUDE

-  und freetype2\include verweisen. Z.B.:

-

-    INCLUDE;E:\freetype2\include

-

-- In der Datei freetype2/include/Ft2build.h muss zu Beginn

-  ein #include "ATARI.H" wie folgt eingef�gt werden:

-

-    #ifndef __FT2_BUILD_GENERIC_H__

-    #define __FT2_BUILD_GENERIC_H__

-

-    #include "ATARI.H"
