Missing library file?

[pmguy]

I am trying to build the AES crypto example in the SDK <install_dir>\nrf5sdk\v16\nRF5SDK160098a08e2\examples\crypto\nrf_crypto\aes\aes_all_cli (nrf_crypto_aes.eww).

Compilation and assembly appears to proceed fine but I receive this errorduring the attempt to link:

1> Generating linker script ‘nrf_crypto_aes_pca10040.ld’
1> Linking nrf_crypto_aes_pca10040.elf
1> C:/Program Files/SEGGER/SEGGER Embedded Studio for ARM 5.50/gcc/arm-none-eabi/bin/ld: cannot find ../../../../../../../../external/micro-ecc/nrf52hf_armgcc/armgcc/micro_ecc_lib_nrf52.a: No such file or directory
Build failed

Looking in the referenced location I can indeed see that file 'micro_ecc_lib_nrf52.a' is not present (nor can I find it anywhere else). Please can you help/advise?

Hello,

Could you confirm for me that you have completed the micro-ecc backend installation and configuration?
Did this complete without errors?

Best regards,
Karl

No, of course not!  My first step was to compile/link/download/run a project from the examples crypto directory and there was no mention there of having to carry out any library building or configuration before attempting to build the project.

Might I suggest that the documentation for these examples be updated?  I am sure that I am not the only person who would go directly to the source examples and pick one and hit "build"!

Thanks for the reply though; I will take a look at what is involved

I agree that this should be emphasized, so I've created an internal ticket to have this reviewed, thanks for bringing this up!
