How do you debug your code PQCgenKAT_kem.c I am getting below error.

cc -o PQCgenKAT_kem -g2 /Users/kursatc/kyber/ref/PQCgenKAT_kem.c

It is fine when you compile it. I am trying to debug code step by step in CLion. Did you try it ? Here are the steps which I follow:

1-) Download algorithm from the page : https://csrc.nist.gov/Projects/post-quantum-cryptography/selected-algorithms-2022
2-) Open Folder in CLion.
3-) Select Algorithm Implementation Type
4-) Go kyber512 or kyber1024
5-) Open PQCgenKAT_kem.c in CLion IDE.
6-) Open Terminal in CLion.
7-) Run "make" command in kyber512 directory
6-) Click Run ico next to the main function at line 26. Then select debug.

I am getting same error when I try to Build (ctrl +f9) or Debug my project.

How did you debug your project in your development cycle?

Sorry for missing some details.

If you want to debug your project. You need below steps:

1-) Create CMakeList.txt
2-) Include it into your project folder.
3-) Open your project folder with CLion.
4-) Select CMake project in "Open or Import Project" window
5-) Make sure related configurations are generated in "Open Project Wizard" window.
Related configurations means that Build Type, Toolchain, Generator, CMake Options etc.
6-) CLion will generate debug options.

Dear @cryptojedi , Could you please share me how do you debug your project in your development cycle? Do you want to add specific cases for above steps?

My CMakeList.txt:

cmake_minimum_required(VERSION 3.12)
project(PQCgenKAT_kem C)

set(CMAKE_C_STANDARD 11)

# Set the source files and headers
set(SOURCES
        cbd.c
        fips202.c
        indcpa.c
        kem.c
        ntt.c
        poly.c
        polyvec.c
        PQCgenKAT_kem.c
        reduce.c
        rng.c
        verify.c
        symmetric-shake.c
        )

set(HEADERS
        api.h

        rng.h
        verify.h
        symmetric.h
        )

# Add the executable target
add_executable(PQCgenKAT_kem ${SOURCES} ${HEADERS})

# Set compiler flags
target_compile_options(PQCgenKAT_kem PRIVATE -O3 -march=native -fomit-frame-pointer)

# Link the necessary libraries
target_link_libraries(PQCgenKAT_kem crypto)

I'm using a combination of printf-debugging and gdb. I have never used CLion and I'm afraid I cannot offer help here.

Thank you.

Wish you enjoy work.
