专家好：
以前用ccs3.8.1在6455上开发的工程中用到了ti dsp lib中的函数DSP_fft32x32，现用ccs5在6678l的开发板上跑一个小程序还想用DSP_fft32x32函数，但built总是不成功，提示如下：
<Linking>
warning: library "../src/dsplib64plus.lib" contains TI-COFF object files which
are incompatible with the ELF output file. Ensure you are using the proper
library.

library.

--------- ----------------
DSP_fft32x32 ./obj/platforms_utils_test.obj

好像说什么TI-COFF 和ELF output file不匹配，是不是ccs3.3和ccs5的问题？如果是那么ccs5中有没有对应能用的DSP_fft32x32函数？
请教一下！
