CUDA compilation errors on Mac

Question

I\'m using the following Makefile to compile a CUDA C program. This follows pretty much the same pattern that I use in most of my C projects.

TARGET = bfs

GCC =         


        

Answer 1

This seemed to work for me:

TARGET = bfs

SRCDIR = src
OBJDIR = obj
BINDIR = bin
INClDIR = includes

CUDA_INSTALL_PATH := /usr/local/cuda
GCC := $(CUDA_INSTALL_PATH)/bin/nvcc
LIBS := -I. -I$(SRCDIR) -I$(CUDA_INSTALL_PATH)/include -I$(INClDIR)
CUDA_LIBS := -L$(CUDA_INSTALL_PATH)/lib64 -lcudart

SOURCES := $(wildcard $(SRCDIR)/*.cu)
INCLUDES := $(wildcard $(INClDIR)/*.h)
OBJECTS := $(SOURCES:$(SRCDIR)/%.cu=$(OBJDIR)/%.o)
rm = rm -f

$(BINDIR)/$(TARGET) : $(OBJECTS)
        mkdir -p $(BINDIR)
        $(GCC) -o $@  $(OBJECTS)
        @echo "Linking complete!"

$(OBJECTS): $(OBJDIR)/%.o : $(SRCDIR)/%.cu
        @$(GCC) $(LIBS) -c $(SRCDIR)/*.cu -odir $(OBJDIR)
        @echo "Compiled "$<" successfully!"

.PHONEY: clean
clean:
        @$(rm)   $(OBJECTS)
        @echo "Cleanup complete!"
remove: clean
        @$(rm) $(BINDIR)/$(TARGET)
        @echo "Executable removed!"

I tested on linux. You will need to change CUDA_INSTALL_PATH back to wherever it is on your machine.

Note that your use of *.cu on the compile step results in a single invocation of nvcc to compile all the source files. There's nothing wrong with this per se, but it will only generate a single "Compiled ... successfully!" message, as there is only one invocation of nvcc to create all the objects.
