Question

我正在大学写一个包含OpenGL和CUDA代码的程序，我可以用Ubuntu Linux运行它。该程序有很多依赖项，所以我使用makefile，当我在Linux大学时我没有问题。昨天我试着在家里的MacBook上运行它并没有运行。我正确地设置了库路径，但是当我尝试使用makefile进行编译时，我得到以下几行：

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$

这是makefile：

我没有修改用于Linux的makefile，除了两行（以下是旧行）：

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

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

你能帮我吗？

非常感谢!!

您不必使用nvcc链接最终程序。事实上，我强烈反对。 nvcc应仅用于编译.cu文件，其余文件留给gcc / g ++ / clang。

一般来说，迫使nvcc使用特定的编译器是个坏主意。只是让它选择它的默认值。我没有在你发布的Makefile中看到（可能在findcuda.mk中）变量NVCC的定义，我怀疑是否配置了--ccbin标志。

此外，在MacOS X中，OpenGL框架涵盖了OpenGL。库libGL / libGLU用于通过X11服务器（可在MacOS X中使用）运行的支持程序，但MacOS X的X11 / GLX / OpenGL支持是兼容层，不支持CUDA。

因此我建议你改变如下：

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))
