AES example in SDK version 17.0.0 does not compile out of the box

Question

Hello. 
 Trying to compile the AES CBC MAC example out of the box, we get the ferror below. 
 Your help would be appreciated. 
 Many thanks, 
 Andrew 
 
 Building ‘nrf_crypto_aes_cbc_mac_pca10040’ from solution ‘nrf_crypto_aes_cbc_mac_pca10040’ in configuration ‘Release’ 
 .... 
 Linking nrf_crypto_aes_cbc_mac_pca10040.elf cannot find ../../../../../../../../external/micro-ecc/nrf52hf_armgcc/armgcc/micro_ecc_lib_nrf52.a: No such file or directory Build failed

Thanks Hakon. 
 The problem with mico-ecc went a way after a clean install. I'll just have to assume I had introduced the error during setup. Mea culpa. 
 The remaining problem with the uart aes_mac examples has also been tracked down to a missing declaration in nrf_log_backend_rtt.c in the 17.0.0 distribution as follows: 
 const nrf_log_backend_api_t nrf_log_backend_rtt_api; 
 Only the .h f ile reference to the strcuture was found in the distribution: 
 extern const nrf_log_backend_api_t nrf_log_backend_rtt_api. 
 Naturally the linker was complaining, and assoon as we added the declaration to the the .c file, we got a clean compile. 
 Regards, 
 Andrew
