How to get the reference of the SoC library API?

[Hamza]

Hello,

We are currently migrating (or trying to...) from IAR Arm Embedded to Eclipse/GCC.

I'm trying to compile our project using gcc and eclipse. I followed this tutorial : devzone.nordicsemi.com/.../

I managed to build my Makefile and link most files (with some difficulties but seems to be ok now). I am still not able to compile as some function/reference are undefined (and not found in c/h files).

See log:

C:/Users/Teeptrak/Documents/GitHub/BLE-module/library/nrf51_sdk_v810/components/drivers_nrf/pstorage/pstorage.c:597: undefined reference to 'sd_flash_write'

C:/Users/Teeptrak/Documents/GitHub/BLE-module/library/nrf51_sdk_v810/components/drivers_nrf/pstorage/pstorage.c:608: undefined reference to 'sd_flash_page_erase'

C:/Users/Teeptrak/Documents/GitHub/BLE-module/library/nrf51_sdk_v810/components/drivers_nrf/pstorage/pstorage.c:638: undefined reference to 'sd_flash_write'

c:/program files (x86)/gnu tools arm embedded/bin/../lib/gcc/arm-none-eabi/6.3.1/../../../../arm-none-eabi/lib/thumb/v6-m\libc_nano.a(lib_a-sbrkr.o): In function '_sbrk_r': sbrkr.c:(.text._sbrk_r+0xc): undefined reference to `_sbrk' collect2.exe: error: ld returned 1 exit status

These functions/references are, following documentatrion, in SoC library API. I can't find them anywhere else (in c or h files)...

Setup SDK 8.1 GCC 6.3 Eclipse 4.7.0

How can I make my code compile :-). Maybe we are missing something obvious...

Thanks.

It looks like your are compiling with GCC 6.3. Do you have it install in your system ? Check you PATH settings. It could be the root of the cause. GCC 5.4 works fine.

[Torsten Robitzki]

How should a not installed compiler emit error messages?

[Hamza]

It's indeed gcc 6.3 (I edited the question), but the path is set.

Do you think the version of gcc could change something ?

[endnode]

It seems to be missing some references to SoftDevice API, are you sure you are using the same version of SDK and SD header files as you used in IAR? Also that all the paths in your Makefile are present so sd_flash_xxx calls from pstorage module could be resolved?

[Hamza]

Yes, I'm using the same sdk, and all the paths are set in the Makefile. Acctually I got undefined references from functions of the sdk, I included the ones I needed in the Makefile source variable, the errors have gone, there is only this one. It couldn't found the sd_flash_xxx functions defintion.
