问题描述
我已阅读几乎所有关于CUDA,C ++& makefile在这里,但仍然不能解决我的问题。
I've read almost all questions about CUDA, C++ & makefiles here, but still can't figure solution to my problem.
我有一些 .cpp
文件& ;一些 .cu
文件在我的项目的 src /
目录中( .h
&
.cuh
),我想用makefile创建我的应用程序。
I have a some .cpp
files & some .cu
files inside src/
directory of my project (along with .h
& .cuh
), and I'd like to build my application with a makefile.
我尝试这样做:
SRC_DIR = src
OBJ_DIR = obj
CPP_FILES = $(wildcard $(SRC_DIR)/*.cpp)
CU_FILES = $(wildcard $(SRC_DIR)/*.cu)
H_FILES = $(wildcard $(SRC_DIR)/*.h)
CUH_FILES = $(wildcard $(SRC_DIR)/*.cuh)
OBJ_FILES = $(addprefix $(OBJ_DIR)/,$(notdir $(CPP_FILES:.cpp=.o)))
CUO_FILES = $(addprefix $(OBJ_DIR)/,$(notdir $(CU_FILES:.cu=.cu.o)))
$(TARGET) : $(OBJ_FILES) $(CUO_FILES)
$(LD) $(LDFLAGS) $(LIB_CUDA) -o $@ $?
$(CUO_FILES) : $(CU_FILES) $(CUH_FILES)
$(NVCC) $(NVCCFLAGS) $(INCLUDES) -c -o $@ $<
$(OBJ_DIR)/%.o : $(SRC_DIR)/%.cpp $(H_FILES)
$(NVCC) $(NVCCFLAGS) $(INCLUDES) -c -o $@ $<
这是正常的,直到我有一个.cu文件。
然后我尝试:
And it was OK until I've got a second .cu file.And then I tried:
<... previous part stays the same ...>
OBJS = $(patsubst %.cpp,$(OBJ_DIR)/%.o,$(notdir $(CPP_FILES)))
OBJS += $(patsubst %.cu,$(OBJ_DIR)/%.cu.o,$(notdir $(CU_FILES)))
$(TARGET) : $(OBJS)
$(LD) $(LDFLAGS) $(LIB_CUDA) -o $@ $?
$(OBJ_DIR)/%.cu.o : $(SRC_DIR)/%.cu $(CUH_FILES)
$(NVCC) $(NVCCFLAGS) $(INCLUDES) -c -o $@ $<
$(OBJ_DIR)/%.o : $(SRC_DIR)/%.cpp $(H_FILES)
$(NVCC) $(NVCCFLAGS) $(INCLUDES) -c -o $@ $<
但 make 无法弄清楚如何制作 .cuoo
文件。
我应该如何修改这个东西来构建我的应用程序?
But make can't figure out how to make any of the .cu.o
files now.How should I modify this thing to build my application?
提前感谢!
strong>更新 - 使用第二个makefile输出make:
Upd - output of make with second makefile:
/usr/local/cuda/bin/nvcc -I/usr/local/cuda/include -c -o obj/main.o src/main.cpp
/usr/local/cuda/bin/nvcc -I/usr/local/cuda/include -c -o obj/util.o src/util.cpp
make: *** No rule to make target `obj/thrust.cu.o', needed by `DCG'. Stop.

推荐答案
或者你有一个语法错误在你没有显示的地方,的项目不是你所描述的。如果我使用你的Makefile的这个模型:
Either you have a syntax error in your Makefile somewhere you are not showing, or the layout of your project isn't as you have described. If I take this model of your Makefile:
TARGET = nothing
SRC_DIR = src
OBJ_DIR = obj
CPP_FILES = $(wildcard $(SRC_DIR)/*.cpp)
CU_FILES = $(wildcard $(SRC_DIR)/*.cu)
H_FILES = $(wildcard $(SRC_DIR)/*.h)
CUH_FILES = $(wildcard $(SRC_DIR)/*.cuh)
OBJ_FILES = $(addprefix $(OBJ_DIR)/,$(notdir $(CPP_FILES:.cpp=.o)))
CUO_FILES = $(addprefix $(OBJ_DIR)/,$(notdir $(CU_FILES:.cu=.
OBJS = $(patsubst %.cpp,$(OBJ_DIR)/%.o,$(notdir $(CPP_FILES)))
OBJS += $(patsubst %.cu,$(OBJ_DIR)/%.cu.o,$(notdir $(CU_FILES)))
$(TARGET) : $(OBJS)
echo "linking rule : " -o $@ $?
$(OBJ_DIR)/%.cu.o : $(SRC_DIR)/%.cu $(CUH_FILES)
echo ".cu.o rule : " $@ $<
touch $@
$(OBJ_DIR)/%.o : $(SRC_DIR)/%.cpp $(H_FILES)
echo ".o rule : " $@ $<
touch $@
然后我创建一个你所描述的模型:
and then I make a model of what you have described:
$ mkdir src
$ mkdir obj
$ touch src/main.cpp
$ touch src/cuda-utils.cuh
$ touch src/thrust.cu
$ touch src/cuda-utils.cu
$ touch src/util.cpp
$ touch src/main.cpp
$ ls
Makefile obj src
$ ls src
cuda-utils.cu cuda-utils.cuh main.cpp thrust.cu util.cpp
$ ls obj
然后我运行make:
$ make
echo ".o rule : " obj/main.o src/main.cpp
.o rule : obj/main.o src/main.cpp
touch obj/main.o
echo ".o rule : " obj/util.o src/util.cpp
.o rule : obj/util.o src/util.cpp
touch obj/util.o
echo ".cu.o rule : " obj/cuda-utils.cu.o src/cuda-utils.cu
.cu.o rule : obj/cuda-utils.cu.o src/cuda-utils.cu
touch obj/cuda-utils.cu.o
echo ".cu.o rule : " obj/thrust.cu.o src/thrust.cu
.cu.o rule : obj/thrust.cu.o src/thrust.cu
touch obj/thrust.cu.o
echo "linking rule : " -o nothing obj/main.o obj/util.o obj/cuda-utils.cu.o obj/thrust.cu.o
linking rule : -o nothing obj/main.o obj/util.o obj/cuda-utils.cu.o obj/thrust.cu.o
$ ls obj
cuda-utils.cu.o main.o thrust.cu.o util.o
我得到的是正确的。所以如果你有一个问题,它不是从你发布的问题(在原来的版本中的几个拼写错误修复后)。
I get exactly what is expected. So if you are having a problem, it is not coming from what you have posted in your question (after the several "typos" in the original version were fixed).
这篇关于makefile for C ++ / CUDA项目的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!
