在Petalinux创建的应用程序模板，只支持编译一个C文件。

使用下面的文件，可以编译目录下的所有C、C++文件。

APP = qdma-ep-rw

# 
# CC=$(CROSS_COMPILE)gcc
# CXX=$(CROSS_COMPILE)g++

# Common options
CFLAGS= -g -O3 
LIBS = 

# Options for extra libraries
#CFLAGS_OPENCV = `pkg-config opencv --cflags`
#LIBS_OPENCV = `pkg-config opencv --libs`

# Find all C files and create object file list
C_SRC = $(wildcard *.c)
C_OBJ = $(patsubst %c, %o, $(C_SRC))

# Find all Cpp files and create object file list
CPP_SRC = $(wildcard *.cpp)
CPP_OBJ = $(patsubst %cpp, %o, $(CPP_SRC))


# Include directory
INC_PATH=-I. -I./include -I../include

all: build 

build: $(APP)

# Compile C files
.c.o:
	$(CXX) -c $(CFLAGS) $(INC_PATH) -o $@ $< $(LIBS) 

# Compile Cpp files
.cpp.o:
	$(CXX) -c $(CFLAGS) $(INC_PATH) -o $@ $< $(LIBS)


$(APP): $(C_OBJ) $(CPP_OBJ) 
	$(CXX) -o $@ $(C_OBJ) $(CPP_OBJ) $(LDFLAGS) $(LDLIBS)
clean:
	rm -f $(APP) *.o

当使用(CC)，也就是(CROSS_COMPILE)gcc，编译C文件时，petalinux报告下列错误。当改为

Command '['aarch64-xilinx-linux-objcopy', '--only-keep-debug', '/proj/hankf/vck190/v212/dapd-0211-xsa-peta/build/tmp/work/cortexa72-cortexa53-xilinx-linux/qdma-ep-rw/1.0-r0/package/usr/bin/qdma-ep-rw', '/proj/hankf/vck190/v212/dapd-0211-xsa-peta/build/tmp/work/cortexa72-cortexa53-xilinx-linux/qdma-ep-rw/1.0-r0/package/usr/bin/.debug/qdma-ep-rw']' returned non-zero exit status 1.
