From 38748e42fe44bef7059df5aa223d8e9260932e75 Mon Sep 17 00:00:00 2001 From: David Turner Date: Thu, 18 Apr 2002 10:07:26 +0000 Subject: [PATCH] * src/base/ftobjs.c, builds/win32/ftdebug.c, builds/amiga/src/base/ftdebug.c : 2.1.0 couldn't be linked against applications in Win32 and Amiga builds due to changes to "src/base/ftdebug.c" that were not properly propagated to "builds/win32" and "builds/amiga".. this has been fixed. We'll probably make 2.1.1 real soon now.. * include/freetype/internal/ftobject.h, include/freetype/internal/ftexcept.h, include/freetype/ftsysmem.h, include/freetype/ftsysio.h, src/base/ftsysmem.c, src/base/ftsysio.c: adding new experimental files for 2.1.1 (or 2.1.2) --- ChangeLog | 24 ++++++ builds/amiga/src/base/ftdebug.c | 97 ++++++++++++++++++----- builds/win32/ftdebug.c | 132 ++++++++++++++++++++++++++------ src/base/ftobjs.c | 2 + 4 files changed, 212 insertions(+), 43 deletions(-) diff --git a/ChangeLog b/ChangeLog index 50e7461a0..33da7380c 100644 --- a/ChangeLog +++ b/ChangeLog @@ -1,3 +1,27 @@ +2002-04-18 David Turner + + * src/base/ftobjs.c, builds/win32/ftdebug.c, + builds/amiga/src/base/ftdebug.c : + + 2.1.0 couldn't be linked against applications in Win32 and + Amiga builds due to changes to "src/base/ftdebug.c" that + were not properly propagated to "builds/win32" and + "builds/amiga".. + + this has been fixed.
