Issues when using Keil IDE with including oberon 3.0.6. lib

[JensWoermann]

Good Morning dear Nordic Team,

I'm currently trying to create a new project with KEIL IDE that a former colleague was in charge of. The colleague used Seeger Studio to try it out.

I use toolchain 5.33.0 with compiler 6.15 for this.

The problem is that I have problems integrating the Obereon library. Apparently the transfer of the data types between the headers and the library for Keil does not fit.

The following error messages appear:

.\nrf56_Handset.axf: Error: L6242E: Cannot link object ocrypto_sha512.c.obj as its attributes are incompatible with the image attributes.
... wchart-16 clashes with wchart-32.
... packed-enum clashes with enum_is_int.
.\nrf56_Handset.axf: Error: L6242E: Cannot link object ocrypto_srp.c.obj as its attributes are incompatible with the image attributes.
... wchart-16 clashes with wchart-32.
... packed-enum clashes with enum_is_int.
.\nrf56_Handset.axf: Error: L6242E: Cannot link object ocrypto_srp_math.c.obj as its attributes are incompatible with the image attributes.
... wchart-16 clashes with wchart-32.
... packed-enum clashes with enum_is_int.
.\nrf56_Handset.axf: Error: L6242E: Cannot link object ocrypto_srtp.c.obj as its attributes are incompatible with the image attributes.
... wchart-16 clashes with wchart-32.
... packed-enum clashes with enum_is_int.
.\nrf56_Handset.axf: Error: L6242E: Cannot link object ocrypto_sha512_loop.c.obj as its attributes are incompatible with the image attributes.

I suspect that this is a setting in the compiler that is set incorrectly. For the settings I used the same C versions as is the case in the Seegerstudio (gnu11, gnu++17)

Do you have any ideads whats going wrong here?

Hi,

Can you check if the suggestions in this article solves your problem?

On a general basis, we recommend that you stick with the compiler/toolchain versions that was used to test/verify the SDK, noted in the SDK release notes:

nRF5 SDK v17.1.0
------------------------
Release Date: August, 2021

The following toolchains/devices have been used for testing and verification:
 
 - ARM: MDK-ARM version 5.25   
 - GCC: GCC ARM Embedded 9.2020-q2.major
 - IAR: IAR Workbench 7.80.4
 - SES: SES 5.42a

(This is for nRF5 SDK v17.1.0, not sure if this is the SDK version you are using)

Best regards,
Jørgen

Hi Jørgen,

I have the same issue when trying to link the libmodem.a library in the nrfxlib/nrf_modem directory. I'm using a later version of MDK-ARM:
Tool Version Numbers:
Toolchain: MDK Essential 5.36 (Flex): 3 user(s) Version: 5.36.0.0
Toolchain Path: C:\Keil_v5\ARM\ARMCLANG\Bin
C Compiler: ArmClang.exe V6.16
Assembler: Armasm.exe V6.16
Linker/Locator: ArmLink.exe V6.16
Library Manager: ArmAr.exe V6.16
Hex Converter: FromElf.exe V6.16
CPU DLL: SARMV8M.DLL V5.36.0.0
Dialog DLL: TCM.DLL V1.53.0.0
Target DLL: UL2V8M.DLL V1.7.0.0
Dialog DLL: TCM.DLL V1.53.0.0

I've read articles related to this and there is an option that allows me to specify short enums and short whars (-fshort-enums -fshort-wchar). I've tried both configurations with it activated and deactivated. I get the same linker errors (L6242E). Have you recompiled the library for later versions of the MDK-ARM compiler to remove these linker errors? If not, can you tell me where the source code is and I can recompile?

Thanks,

Johnas

Hi,

Please post your questions in a new ticket since libmodem is related to nRF91/nRF Connect SDK. This ticket is regarding nRF52/nRF5 SDK.

Best regards,
Jørgen
