Hello,

        When I tried to build the project of DSP_fft16x16_66_BE_COFF on the ccs v9, I have encountered some problems. It is shown as the following:

     

**** Build of configuration Debug for project DSP_fft16x16_66_BE_COFF ****

"C:\\ti\\ccs920\\ccs\\utils\\bin\\gmake" -k all

Building target: "DSP_fft16x16_66_BE_COFF.out"
Invoking: C6000 Linker

gmake: *** [DSP_fft16x16_66_BE_COFF.out] Error 1
gmake: Target 'all' not remade because of errors.

**** Build Finished ****

And what I have installed includes the dsplib_c66x_3_4_0_4,   fftlib_k2hx_2_0_0_2,  mathlib_rts_c66x_3_1_2_1, processor_sdk_rtos_k2e_6_01_00_08, and some other softwares.

So what's the solution to this problem... Hope for the reply. Do need the help.

Yours,

Suafie

    Suafie,

    Did you modify the DSP_fft16x16 example included with the SDK? I ask because I see a LE/ELF version as an example but not a BE/COFF version.

    suafie said:
    error #10008-D: cannot find file "../../../../../lib/dsplib.lib"
    error #10008-D: cannot find file "../../../../../lib/dsplib_cn.lib"

    The reason for this error is that the linker is not able to find these libraries. Make sure you add the paths to these libraries to the project's Linker->File Search Path option.
