error: L6002U could not open file

Hi Nordic team

I compile the example ble_app_interactive  in keil ver.5.24.

And the below error message occur.

.\_build\nrf52832_xxaa_s132.axf: error: L6002U: Could not open file ..\..\..\..\..\..\..\external\nrf_oberon\lib\nrf52\oberon_short_wchar_2.0.4.lib: No such file or directory
Finished: 0 information, 0 warning, 0 error and 1 fatal error messages.
".\_build\nrf52832_xxaa_s132.axf" - 1 Error(s), 0 Warning(s).
Target not created.

 I have compiled other examples and it works fine. (except: pca10040 and pca10056 in ble_app_interactive )

What is exactly happened ?

By the way, I didn`t plug in my J link while compiling.

I am not able to reproduce this on SDK 15.0.0. Which SDK version are you using? Have you checked that the path to oberon_short_wchar_2.0.4.lib is correct relative to your Keil project file?

Hi sir

Update my problem first.

I move my whole nRF5_SDK_15.0.0_a53641a under C file.

And above problem disappear, but comes up the below error message.

.\_build\nrf52832_xxaa_s132.axf: error: L6002U: Could not open file ..\..\..\..\..\..\..\external\micro-ecc\nrf52hf_keil\armgcc\micro_ecc_lib_nrf52.lib: No such file or directory

I know micro_ecc_lib_nrf52.lib have to compile by gcc.

But I tried some many way on this page, the make command still not work. (new gay in gcc, sor....

 It is possible to ignore this library to compile this project?

many Thx

Hi,

I'm glad to see you got the nrf_oberon issue sorted out.

You can fix the mico-ecc issue by downloading and building the micro-ecc library. This is easily done by navigating to <SDK>\external\micro-ecc\ and running the build_all.bat file (alternatively build_all.sh if you are on Linux or Mac). You can also remove the micro-ecc library file (micro_ecc_lib_nrf52.lib) from the project if you don't use it and have disabled in in sdk_config.h.

Hi sir

My OS is Win7X64 and I have do the instruction you say, running the batch file.

After the consol pop out, is there any new item will be made or install?

Because the error message still the same ....

Hi sir

Glad to share this moment!! I fix it!!

The reason why I can`t through the gcc is the new version Mingw change the make.exe to Mingw-32-make.exe.

After change the file and path, everything works functional.

But I still can`t understand the meaning of disable the crypto in sdk_config.h....

It means to remove the <e> NRF_CRYPTO_ENABLED - nrf_crypto - Cryptography library ?
