无法在Mac OS X上编译CUDA + OpenGL程序El Capitan

Question

我正在编写一个包含OpenGL和CUDA代码的程序，我可以在Ubuntu Linux上运行它。该程序有很多依赖关系，所以我使用makefile，当我在Linux大学时，我没有任何问题。昨天我试着在家里的MacBook上运行它，但没有运行。我设置库的路径正确，但是当我尝试使用生成文件我得到以下行来编译：

MBP-di-Nicolo:MATRIX_TEST Nico$ make 
/Developer/NVIDIA/CUDA-7.5/bin/nvcc -ccbin g++ -m64 -Xcompiler -g -Xcompiler -arch -Xcompiler x86_64 -g -G -Xlinker -rpath -Xlinker /Developer/NVIDIA/CUDA-7.5/lib -Xlinker -framework -Xlinker GLUT -o Matrix_test my_utils2.o Matrix_test.o Matrix.o -L/System/Library -L/System/Library/Frameworks/OpenGL.framework/Libraries -lGL -lGLU ../../common/lib/darwin/libGLEW.a -L. -lrt 
nvlink fatal : Could not find fatbin in 'my_utils2.o' 
nvlink fatal : elfLink internal error 
make: *** [Matrix_test] Error 1 
MBP-di-Nicolo:MATRIX_TEST Nico$ 

这里的生成文件：

我没有修改用于Linux的makefile文件，除了两条线（以下是旧的）：

# Location of the CUDA Toolkit 
CUDA_PATH ?= "/usr/local/cuda-7.5" 

# Common includes and paths for CUDA 
EXT_LIB = /usr/local/lib 

你能帮助我吗？

非常感谢！

您不必使用nvcc链接最终的程序。实际上，我强烈建议不要这样做。 nvcc应该只用于编译.cu文件，其余部分留给gcc/g ++/clang。

通常，强制nvcc使用特定的编译器是一个坏主意。让它选择它的默认值。我没有在您发布的Makefile中找到（很可能在findcuda.mk）变量NVCC的定义，我怀疑是否配置了--ccbin标志。

此外，在MacOS X中，OpenGL由OpenGL框架覆盖。库libGL/libGLU用于支持通过X11服务器运行的程序（MacOS X中提供），但MacOS X的X11/GLX/OpenGL支持是兼容层，不支持CUDA。

因此，我建议你更改如下：

LIBRARIES += ../../common/lib/darwin/libGLEW.a 
LDFLAGS += -framework GLUT -framework OpenGL 

all: build install 

$(PROGNAME): my_utils2.o Matrix_test.o Matrix.o 
    $(LD) $(LDFLAGS) -o $@ $+ $(LIBRARIES) -L. 

install: $(PROGNAME) 
    mkdir -p ./bin/$(OS_ARCH)/$(OSLOWER)/$(TARGET)$(if $(abi),/$(abi)) 
    cp $@ ./bin/$(OS_ARCH)/$(OSLOWER)/$(TARGET)$(if $(abi),/$(abi))
