From 66bbf336c6af7353ef0aeed58002c46543b30635 Mon Sep 17 00:00:00 2001 From: rubidium Date: Tue, 2 Jan 2007 19:19:48 +0000 Subject: (svn r7759) -Merge: makefile rewrite. This merge features: - A proper ./configure, so everything needs to be configured only once, not for every make. - Usage of makedepend when available. This greatly reduces the time needed for generating the dependencies. - A generator for all project files. There is a single file with sources, which is used to generate Makefiles and the project files for MSVC. - Proper support for OSX universal binaries. - Object files for non-MSVC compiles are also placed in separate directories, making is faster to switch between debug and release compiles and it does not touch the directory with the source files. - Functionality to make a bundle of all needed files for for example a nightly or distribution of a binary with all needed GRFs and language files. Note: as this merge moves almost all files, it is recommended to make a backup of your working copy before updating your working copy. --- music/qtmidi.c | 371 --------------------------------------------------------- 1 file changed, 371 deletions(-) delete mode 100644 music/qtmidi.c (limited to 'music/qtmidi.c') diff --git a/music/qtmidi.c b/music/qtmidi.c deleted file mode 100644 index 6f0a215d0..000000000 --- a/music/qtmidi.c +++ /dev/null @@ -1,371 +0,0 @@ -/* $Id$ */ - -/** - * @file qtmidi.c - * @brief MIDI music player for MacOS X using QuickTime. - * - * This music player should work in all MacOS X releases starting from 10.0, - * as QuickTime is an integral part of the system since the old days of the - * Motorola 68k-based Macintoshes.
