error: '__STATIC_FORCEINLINE' does not name a type; did you mean '__STATIC_INLINE'?

[ardit93]

I'm creating a nn project on a nrf52 using a makefile on MacOS. At first I'm trying to reimplement the cifar example. I'm using CMSIS 5.6. I attached the makefile. I have already added all the needed source files in the makefile as well as the include folders. When I try to build the project, the following errors occur /CMSIS_5-5.6.0/CMSIS/NN/Include/arm_nnsupportfunctions.h:210:1: error: 'STATIC_FORCEINLINE' does not name a type; did you mean '__STATIC_INLINE'? STATIC_FORCEINLINE q31_t arm_nn_sat_doubling_high_mult(const q31_t m1, const q31_t m2) ^~~~~~~~ STATIC_INLINE /CMSIS_5-5.6.0/CMSIS/NN/Include/arm_nnsupportfunctions.h:242:1: error: '__STATIC_FORCEINLINE' does not name a type; did you mean 'STATIC_INLINE'? STATIC_FORCEINLINE q31_t arm_nn_divide_by_power_of_two(const q31_t dividend, const q31_t exponent) ^~~~~~~~ STATIC_INLINE

I tested the same configuration with CMSIS 5.4.0 and it compiled and linked successfully. The compiler, I'm using is gcc-arm 7.3.1. Makefile.txt

Hi @ardit93,

it looks like your include folders are not set correctly. Quickly glancing over your Makefile.txt:

  $(CMSIS_DIR)/CMSIS/Core/Include \
  $(CMSIS_DIR)/CMSIS/DSP/Include \
  $(CMSIS_DIR)/CMSIS/NN/Include \
  $(CMSIS_DIR)/CMSIS/Core_A/Include \
  $(CMSIS_DIR)/CMSIS/Driver/Include \

You must not add Core/Include and Core_A/Include at the same time. Both folders contain header files with the same name, hence you are causing ambiguities. If your target it Cortex-M then you only need Core/Include.

I'd recommend to check the ARM.CMSIS.pdsc file to see which files and folders are required for your configuration. The define __STATIC_FORCEINLINE is in Core/Include/cmsis_gcc.h. Please be sure this header file is picked up, properly. You could for instance run the compiler with preserving the preprocessed source code (intermediate files) by adding -save-temps command line argument.

Cheers, Jonatan

Hello Jonatan,

thanks for pointing that out. Although I removed the Core_A, the same error is coming up again.

Hi @ardit93,

please check in which compilation unit this error does occur, i.e. which .c file. Add -save-temps to the Compiler command line and attach the preprocessed intermediate file of this compilation unit. We need to check the actual preprocessing result and include chain. The should be a path ending up including cmsis_gcc.h file.

Cheers, Jonatan

I saw that the makefile was including the cmsis_gcc.h included in the nordic sdk. Correcting the path resulted in another error(See the following errors). I could compile it by using the files provided by nordic but the copy_table variables are unknown to me. Coul you please explain to me what these variables are or direct me to the documentation resorces?

Thank you and cheers. Ardit

Hi @ardit93,

it looks like you are mixing up certain parts. If you are using the C startup routine from CMSIS you need to use the linker script and stuff as provided by CMSIS.

The copy_table and zero_table symbols belong to the startup code required on bare metal targets. These linker generated tables specify which RAM areas needs to be initialized with static data or with zeros. I cannot give you much help about your specific application.

Please try to get a minimal example (i.e. empty main) running, first. If you are able to compile and run to main you are good to add more elaborated stuff.

Cheers, Jonatan
