How should a very simple Makefile look like for Cuda compiling under linux

I want to compile a very basic hello 开发者_如何学Cworld level Cuda program under Linux. I have three files:

• the kernel: helloWorld.cu
• main method: helloWorld.cpp
• common header: helloWorld.h

Could you write me a simple Makefile to compile this with nvcc and g++?

Thanks,

Gabor

I've never heard of Cuda before, but from the online documentation it looks as if X.cu is supposed to be compiled into X.o, so having helloWorld.cu and helloWorld.cpp is not a good idea. With your permission I'll rename the "kernel" helloKernel.cu, then this should work:

NVCC = nvcc

helloWorld.o: helloWorld.cpp helloWorld.h
    $(NVCC) -c %< -o $@

helloKernel.o: helloKernel.cu
    $(NVCC) -c %< -o $@

helloWorld: helloWorld.o helloKernel.o
    $(NVCC) %^ -o $@

(Note that those leading spaces are tabs.)

If that works, try a slicker version:

NVCC = nvcc

helloWorld.o: %.o : %.cpp %.h
helloKernel.o: %.o : %.cu

%.o:
    $(NVCC) -c %< -o $@

helloWorld: helloWorld.o helloKernel.o
    $(NVCC) %^ -o $@

Just in case, here's my variant. I use it to compile CUDA projects on Mac, but I think it will suit Linux too. It requires CUDA SDK.

BINDIR = ./ # places compiled binary in current directory
EXECUTABLE := helloWorld

CCFILES := helloWorld.cpp
CUFILES := helloWorld.cu

# an ugly part - setting rootdir for CUDA SDK makefile
# look for common.mk - I don't know where SDK installs it on Linux -
# and change ROOTDIR accordingly 
ROOTDIR := /Developer/GPU\ Computing/C/common

include $(ROOTDIR)/../common/common.mk

My version, verbose but transparent:

myapp: myapp.o
    g++ -fPIC -o $@ $< -L /usr/local/cuda/lib -lcudart

myapp.o: myapp.cu
    /usr/local/cuda/bin/nvcc --compiler-options -fno-strict-aliasing \
    -I/usr/local/cuda/include \
    -DUNIX -O2 -o $@ -c $<

matrixMul: matrixMul.o
    g++ -fPIC -o $@ $< -L /usr/local/cuda/lib -lcudart

# It MUST be named .cu or nvcc compiles as regular C !!! (no __global__)
matrixMul.o: matrixMul.cu
    /usr/local/cuda/bin/nvcc --compiler-options -fno-strict-aliasing \
    -I/usr/local/cuda/include \
    -DUNIX -O2 -o $@ -c $<

Here is an example what my current project looks like. As you can see there is a few OpenGL libraries

ce : cudaExample.c cudaExample.h
    cp cudaExample.c cudaExample.cu
    /usr/local/cuda/bin/nvcc -arch=sm_20 -o ce -lglut -lGL -lGLU -lXext -lXmu -lX11 -lm  cudaExample.cu

then run make ce and ./ce
