How to resolve this error ..\..\..\..\..\..\..\components\libraries\ecc\ecc.c(56): error: #5: cannot open source input file "uECC.h": No such file or directory

Hi,

We are using nrf51422 in our project and SDK we are using is 12.3 and soft device is S130. In our project we need Bluetooth device should be connected to upto 3 devices so, we are tring the example program  ble_app_multirole so when i compiled this program i got this error "..\..\..\..\..\..\..\components\libraries\ecc\ecc.c(56): error:  #5: cannot open source input file "uECC.h": No such file or directory".

I also read the link to attach the micro ecc library file https://infocenter.nordicsemi.com/index.jsp?topic=%2Fstruct_sdk%2Fstruct%2Fsdk_nrf5_latest.html&cp=5_0file:///C:/Users/Admin/AppData/Local/Temp/Rar$EXa5692.47559/nrf5/getting_started_precompiled.html

so what i have done is i copied the uecc.h  file and attached into the specific folder

• InstallFolder\external\micro-ecc\nrf52_keil\armgcc

After attaching header also still i am getting this error

plz tell me how to resolve this problem.

So have you checked that the file does actually exist at all ?

If it does exist, is it in a location where the tools are configured to find it?

You haven't said what tools you're using, or what platform they're running on. If you're on Linux, remember that it is case-sensitive...

I have tried your method

Note that "my (sic) method" just mentioned the Include Path - which, as the name suggests, relates to files referenced via #include

but still i am getting error as like this

No, that's a different error:

chandanaraju said:

micro_ecc_lib_nrf51.lib: No such file or directory

That's a .lib file - a library - not a header file!

There is a separate Path setting to tell the Linker where to find libraries.

Again, this is standard project setup - nothing specifically to do with Nordic - so look in the Keil documentation

Thanks for replying.

can you plz tell me how to include library file

[awneil]

Again, the standard Keil documentation will tell you that - it's not a special Nordic thing.

I think that you can just add it to the Project, then uVision will know what to do with it, and where it is ...
