在android 上面 运行纯C helloworld

由于要测系统的CPU属性，需要独立编译应用程序，便试了下编译纯C 程序，测试通过。
CC         := $(NDK_BASE)/toolchain/arm-eabi/bin/arm-eabi-gcc
AR         := $(NDK_BASE)/toolchain/arm-eabi/bin/arm-eabi-ar
INC        := -I$(NDK_BASE)/include/bionic/arch-arm/include \
 -I$(NDK_BASE)/include/bionic/include \
 -I$(NDK_BASE)/include/kernel/include \
 -I$(NDK_BASE)/include/libm/include \
 -I$(NDK_BASE)/include/libm/include/arm \
 -I$(NDK_BASE)/include/libstdc++/include
LINK       := -nostdlib -Bdynamic \
     -Wl,-T,$(NDK_BASE)/config/armelf.x \
     -Wl,-dynamic-linker,/system/bin/linker \
     -Wl,-z,nocopyreloc \
     -L$(NDK_BASE)/lib \
     -Wl,-rpath-link=$(NDK_BASE)/lib \
    $(NDK_BASE)/lib/crtbegin_dynamic.o
POSTLINK := $(NDK_BASE)/lib/crtend_android.o
%.o: %.cpp
 $(CC) $(CFLAGS) -fno-exceptions -fno-rtti $(INC) -o $@ -c $<
 
%.o: %.c
 $(CC) $(CFLAGS) $(INC) -o $@ -c $<
 include ./config.mk
EXECUTABLE := TEST
SOURCES    := main.c
OBJECTS    := $(SOURCES:.c=.o)
LIBS       := -lc -lm
all: $(EXECUTABLE)
# need $(LINK) before all objects and $(POSTLINK) after all objects for
# android runtime setup.
TEST: $(OBJECTS)
 $(CC) $(LINK) -o $@ $(OBJECTS) $(LIBS) $(POSTLINK)
clean:
 rm -rf *.o
 rm EXECUTABLE
测试程序 就是 printf("Hello world")
另外注意下，一般上传到手机data目录，并chmod下
