RM48L952: CMSIS DSP library compile warning

Tool/software:

Hello,

I am trying to build the CMSIS DSP library with the CCS ti-cgt-arm_20.2.7.LTS.

I have encounter several problems which i am looking for your support:

When building the library, there is a compiler warning about the redefinition of the macro _packed. I have found another thread which talks about the same problème: https://e2e.ti.com/support/microcontrollers/arm-based-microcontrollers-group/arm-based-microcontrollers/f/arm-based-microcontrollers-forum/678357/ccs-tms570ls1224-compiler-warning-is-redefinition-of-macro-__packed-when-using-cmsis-dsp-library

For the moment, i have applied the same solution which comment the ligne in type_defs.h.

Just to be sure, Is this still the only solution ?

During the compile of the library, the warning "#2104-D: attribute "__packed__" does not apply here" have appeared several times on the lignes in the file arm_math.h (for example, ligne 4632).
For the moment, I have suppressed the warning but is there a cleaner way to eliminate the warning?

Thank you for your support.

I think this is the only solution. And i too don't find any other solution except this.

For this issue also i find the same solution of warning suppression. Please take a look on below thread:

(7) Compiler predefined symbol __TI_GNU_ATTRIBUTE_SUPPORT__ - Code Composer Studio forum - Code Composer Studio︎ - TI E2E support forums

Thanks & regards,

Hello,

Thank you for your reply.

I was thinking the same thing. Thank you for your confirmation.

Yes, I have seen the thread but the difference is that I did not use --strict_ansi option (i use -c99). Furthermore, it talks about the Flash F021 library (which I will need as well but not compiled yet for the moment...).

Since the thread seems to talk in a context different from mine, I was convinced that the thread is not really applicable to my problem.

If you confirme that is the only solution, then i will apply the solution. However, as said in the other thread, this is not a "safe" solution.

Thank you again.

Agreed but we don't have any other solution.
