PROCESSOR-SDK-RTOS-J784S4: Build error including FFTlib in Vision Apps

Part Number: PROCESSOR-SDK-RTOS-J784S4
Other Parts Discussed in Thread: FFTLIB

Hi.

I'm developing an application within Vision Apps that uses the FFTLIB library.
I'm using the ti-processor-sdk-rtos-j784s4-evm-11_00_00_06 SDK.
I added the FFTLIB to Vision Apps by inserting the following lines into vision_apps/platform/j784s4/rtos/concerto_c7x_inc.mak:
ADDITIONAL_STATIC_LIBS += FFTLIB_C7120.lib
ADDITIONAL_STATIC_LIBS += FFTLIB_common_C7120.lib

When I build VisionApps I get the following error:

I performed similar operations on the J721E board with the SDK sdk-rtos-j721e-evm-10_00_00_05 and don't recall encountering these errors.
What am I doing wrong?

    Hi Andrea,

    I am looking into this, I will try this from my end and get back to you.

    Hi Andrea,

    The issue is because some of the c7x common configurations are defined in both fftlib repo and mmalib repo. Symbols defined in FFTLIB_common_C7120.lib is also defined in common_C7120.lib as reported by the logs.

    Can you not link the FFTLIB_common_C7120.lib in the vision_apps. This will solve the build issue but I am not sure is there any difference in the symbol definition. 

    Do proceed with this and let me know if there are any issues. I will raise a bug internally to address this issue.

    Regards,
    Gokul
