makefile中CFLAGS+=-DPOSGP730-DUSE_PHONE-D__GNU_C__-DFS_EXT3-Wall$(INCPATH)

ifeq($(strip$(pl)),posa)x09x09如果返回为空,posa

else

#CROSS_COMPILE=arm-unknown-linux-gnu-

CROSS_COMPILE=arm-linux-

CC=$(CROSS_COMPILE)gcc

LD=$(CROSS_COMPILE)ld

RM=rmx09x09//删除

CP=cpx09x09//拷贝

endif

CFLAGS+=-DPOSGP730-DUSE_PHONE-D__GNU_C__-DFS_EXT3-Wall$(INCPATH)-DNDEBUG$(CROSS_CFLAGS)-O2-Wl,-rpath,./

龚晓峰回答:
  -D*表示:#define*   如:-DPOSGP730等价于#definePOSGP730   -Wall表示打开所有编译告警信息   -O2表示优化级别.   -Wl,-rpath,./为传递给连接器的选项,表示程序执行时的库加载路径   另:怀疑该处有误:$(INCPATH)应为-I$(INCPATH)
