IAR linker Error[Li005]

[jj]

I'm having compilation error, and got a couple of errors similar to the examples below:

Error[Li005]: no definition for "sha256_desc" [referenced from C:\Users\........\_build\main.o] 

and

Error[Li005]: no definition for "hash_memory" [referenced from C:\Users\..........\_build\hmac_init.o] 

I've already included the necessary includes in the main.c file where function is. But the hmac_init has no header file, so no include on it. I tried adding hmac_init.c at the left side of the IDE by right clicking on the folder Application -> Add -> Add Files... then add hmac_init.c file. However, it did not appear under the application folder even after doing so.

The supposedly 'missing' definition of eg "hash_memory" is indeed declared in the hmac_init file. I don't know how to proceed, please help.

Hi,

Right click on the project under "Files", and click on "Options..."

Under Category, selected C/C++ Compiler. In the Preprocessor tab, add the path to where the file hmac_init.c is located. Do the same in the Assembler tab afterwards.

After that, try to add the file to the "Application" folder again.

Hi there, I already add the path previously under C/C++ Compiler before posting this question. Then, I just tried to do the same to Assembler tab as per you said. However, adding the 'hmac_init.c' file to Application folder still does not appear.

Make sure that the file is not added in one of the other folders in the project. If the file you are trying to add, is already included in e.g. the "Board Support" folder, it will not show up in the "Application" folder.

I removed the files from other folder, and added it to "Application folder". This indeed make the c files appear under "Application" folder, but still the same compilation errors appeared.

Is sha256_desc and hash_memory functions ?

You could try to create a hmac_init.h where you declare them, and then include this header file.

If you are still stuck, you can zip the project and sent it to me, and I can take a closer look at this.
