我正在尝试从项目中编译示例，以下代码是makefile：
CC = g++
ifeq ($(shell sw_vers 2>/dev/null | grep Mac | awk '{ print $$2}'),Mac)
CFLAGS = -g -DGL_GLEXT_PROTOTYPES -I./include/ -I/usr/X11/include -DOSX
LDFLAGS = -framework GLUT -framework OpenGL -L./lib/mac/ \
-L"/System/Library/Frameworks/OpenGL.framework/Libraries" \
-lGL -lGLU -lm -lstdc++ -lGLEW -lfreeimage
else
CFLAGS = -g -DGL_GLEXT_PROTOTYPES -I./include/ -I/usr/X11R6/include -I/sw/include \
-I/usr/sww/include -I/usr/sww/pkg/Mesa/include
LDFLAGS = -L./lib/nix -L/usr/X11R6/lib -L/sw/lib -L/usr/sww/lib \
-L/usr/sww/bin -L/usr/sww/pkg/Mesa/lib -lglut -lGLU -lGL -lX11 -lGLEW -lfreeimage
endif
RM = /bin/rm -f
all: mytest3
mytest3: mytest3.o shaders.o shaders.h geometry3.h
$(CC) $(CFLAGS) -o mytest3 shaders.o mytest3.o $(INCFLAGS) $(LDFLAGS)
mytest3.o: mytest3.cpp shaders.h geometry3.h
$(CC) $(CFLAGS) $(INCFLAGS) -c mytest3.cpp
shaders.o: shaders.cpp
$(CC) $(CFLAGS) $(INCFLAGS) -c shaders.cpp
clean:
$(RM) *.o mytest3 *.png
所以我尝试了：“make”，我得到了：
$ make
g++ -g -DGL_GLEXT_PROTOTYPES -I./include/ -I/usr/X11R6/include -I/sw/include -I/usr/sww/include -I/usr/sww/pkg/Mesa/include -o mytest3 shaders.o mytest3.o -L./lib/nix -L/usr/X11R6/lib -L/sw/lib -L/usr/sww/lib -L/usr/sww/bin -L/usr/sww/pkg/Mesa/lib -lglut -lGLU -lGL -lX11 -lGLEW -lfreeimage

我安装了过剩：
$ find /usr -name glut.h
/usr/local/cuda-5.0/extras/CUPTI/include/GL/glut.h
/usr/local/cuda-5.0/samples/common/inc/GL/glut.h
/usr/include/GL/glut.h
$ locate libglut
/usr/lib/libglut.so
/usr/lib/gcc/x86_64-linux-gnu/4.4/libglut.so
/usr/lib/x86_64-linux-gnu/libglut.a
/usr/lib/x86_64-linux-gnu/libglut.so
/usr/lib/x86_64-linux-gnu/libglut.so.3
/usr/lib/x86_64-linux-gnu/libglut.so.3.9.0
所以我不知道为什么编译器正在搜索“gcc”路径，它应该可以正常工作......
我也试过：
sudo ln -s /usr/lib/x86_64-linux-gnu/libglut.so /usr/lib/gcc/x86_64-linux-gnu/4.4.7/libglut.so
但仍然无法正常工作。
我在 ubuntu 12.10 上，我首先安装了：
sudo apt-get install freeglut3-dev glew-utils libglew1.6-dev libfreeimage-dev
sudo apt-get install build-essential
怎么了？
