Cannot build CLion project with .asm file

Question

running CLion on Linux, I've been trying to get .asm files to work. This is how my test project looks like (it worked 100% on Windows/Mac, only had to add .intel_syntax in the .asm file).

Installed the NASM Assembly Support plugin.

main.c:

#include <stdio.h>

extern long tes(long);

int main() {
    printf("%ld", tes(5));
    printf("Hello, World!\n");
    return 0;
}

tes.asm:

.text:

.global tes

tes:
    mov rax, edi
    ret

CMakeLists.txt:

cmake_minimum_required(VERSION 3.15)
project(Testt C)
enable_language(C ASM)

set(CMAKE_C_STANDARD 99)

set ( SOURCES 
        main.c 
        tes.asm)

add_executable(program  ${SOURCES} )

How do I configure CLion so as to use tes as a method in C? I'm expecting tes(x) = x, but somehow, my project doesn't compile:

 ====================[ Build | program | Debug ]=================================
/snap/clion/99/bin/cmake/linux/bin/cmake --build /home/user/CLionProjects/Testt/cmake-build-debug --target program -- -j 4
make: *** No rule to make target 'program'.  Stop.

Any help is appreciated!

I know you didn't ask this, and didn't get that far yet, but for future reference: your code won't assemble with `nasm` for multiple reasons. — Jester, Dec 30 '19 at 00:28
Thank you for letting me know, I'm puzzled as it worked perfectly on Windows & Mac today. Why isn't it working? And how do you recommand to integrate .asm files instead? — melian, Dec 30 '19 at 00:48
I can't help you with the cmake stuff, unfortunately. But `.global` is not nasm syntax (delete the leading dot) and `mov rax, edi` is invalid due to different sized registers. Also `.text:` is a label, you probably meant `section .text` (but that is the default anyway). — Jester, Dec 30 '19 at 00:57

You need to use

enable_language(ASM_NASM)

Not sure if the CMake rules will recognize the .asm extension, in that case you might have to add

set_source_files_properties(${ASM_SOURCES} PROPERTIES LANGUAGE ASM_NASM)

Just created these files and they work using MKSYS MSYS with gcc 9 and nasm 2.14:

main.c

#include <stdio.h>

extern long test(long);

int main()
{
    printf("%ld", test(5));
    printf("Hello, World!\n");
    return 0;
}

test.asm

section text

global test

test:
    mov rax, 0
    ret

CMakeLists.txt

cmake_minimum_required(VERSION 3.15)
project(Test)
enable_language(ASM_NASM)

set(CMAKE_C_STANDARD 99)

set(ASM_SOURCES
     test.asm
)

set (SOURCES
     main.c 
     ${ASM_SOURCES}
)

set_source_files_properties(${ASM_SOURCES} PROPERTIES LANGUAGE ASM_NASM)

add_executable(program  ${SOURCES})

Thanks! The first command didn't change anything, the second command throws an error message asking for a CMake NASM compiler. That might be the problem. It's asking for those files: CMakeDetermineNASMCompiler.cmake CMakeNASMCompiler.cmake and the variables CMAKE_NASM_COMPILER_ENV_VAR CMAKE_NASM_COMPILER Where is this NASM compiler? – melian Jan 01 '20 at 01:23
You can look into your cmake installation folder. There should be a modules directory which contains all the compilers known to CMake. Check if there is some file with NASM in the name. i.E. I have CMake 3.15 installed and there is "CMakeASM_NASMInformation.cmake" which means the language name is "ASM_NASM" in this case. I think that files should be installed along with CMake. Did you use "ASM_NASM" with the underscore? If cmake complains about CMakeDetermineNASM... it means that you used "NASM" as the language, as cmake was looking for that. – Devolus Jan 01 '20 at 13:01
