BulletのDemoの使えなさがハンパない

デモプログラムの癖に、移動させるとコンパイルできなくなるってどうよ？

MacOSXにBulletを入れたわけだよ、もちろん正常にframeworkがインストールできたわけね、だからDemoのソースコードたちだけコピーしてとっておいて他のを削除したわけだよ、、、、

普通さ、サンプルプログラムってそのプログラム単体でコンパイルできるでしょ？Bulletはちがうんだよなんか。。。
Demo/BasicDemoをコンパイルするのにDemo/OpenGLが必要なんだよ！

というわけで、オプションすべてつけたはずなのに以下のようなエラーが出るは注目！

コンパイルには、Demo/OpenGLを同梱する必要があります。つまりBasicDemo.cppをコンパイルするときのMakefileはこう

CC = g++ -O2 -Wall

libGL = -framework OpenGL -framework GLUT -framework Foundation
incOpenGL = -I../OpenGL
libBULLET =  -framework BulletCollision -framework BulletDynamics -framework BulletSoftBody -framework LinearMath

SUPPORTFILES = ../OpenGL/*.cpp

LIBS = $(libGL) $(libBULLET)

all:
	$(CC)  BasicDemo.cpp main.cpp $(SUPPORTFILES) $(LIBS) $(incOpenGL) -o AppBasicDemo

気をつけようね！（主に俺w）
