dvsk DMAI,makefile 无语的问题，

见笑了，我搞错了

CE_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/codec-engine_2_25_02_11

CMEM_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/linuxutils_2_25_02_08

FC_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/framework-components_2_25_01_05

XDAIS_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/xdais_6_25_02_11

CODEC_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/codecs-dm365_03_10_00_06

LINUXLIBS_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/linux-devkit/arm-none-linux-gnueabi/usr

LINUXKERNEL_INSTALL_DIR_dm368_al = \

   $(DVSDK_INSTALL_DIR)/psp/linux-kernel-source

CROSS_COMPILE_dm368_al = \

   /library/cs/arm-2009q1/bin/arm-none-linux-gnueabi-

USER_XDC_PATH_dm368_al = \

   $(CE_INSTALL_DIR_dm368_al)/examples

XDC_INSTALL_DIR_dm368_al = \

   $(DVSDK_4_00_INSTALL_DIR_o3530_al)/xdctools_3_16_03_36

EXEC_DIR_dm368_al = \

   $(HOME)/workdir/filesys/opt/dvsdk/$(PLATFORM)

DVSDK_3_10_INSTALL_DIR=${HOME}/dvsdk_3_10_00_16/dvsdk_3_10_00_16

----------------------------

EXEC_DIR_dm368_al = \

   $(HOME)/workdir/filesys/opt/dvsdk/$(PLATFORM)

只有这个 没有转化，但是 EXEC_DIR_dm368_al 在工程里，好像没有第2个；就是错了，也不影响

但是 问题 错在

PLATFORM_OS = $(strip $(PLATFORM_OS_$(PLATFORM)))

PLATFORM_DEVICE = $(strip $(PLATFORM_DEVICE_$(PLATFORM)))

PLATFORM_PERIPHERALS = $(strip $(PLATFORM_PERIPHERALS_$(PLATFORM)))

PLATFORM_XDC_TARGET = $(strip $(PLATFORM_XDC_TARGET_$(PLATFORM)))

PLATFORM_XDC = $(strip $(PLATFORM_XDC_$(PLATFORM)))

我编译的是：368，PLATFORM这个变量将是 o3530_al

怎么解释

请参考dvsdk的编译说明,不要扎到里面去编译.
