VBCC, CLion and CMake sample project

[iliak]

Hi

I'm looking for a (simple) CMake project using VBCC and (ideally with) CLion. I'm stuck at moving from gcc to vbcc in my CMakeFile.

I have to tricks CLion with a nice "set(CMAKE_C_COMPILER_WORKS TRUE)" in the CMakeLists.txt, but I have the nice following error :

Compiler exited with error code 1: /opt/vbcc/bin/vc -xc +aos68k ~/dev/kernel_amiga/rom/libraries/exec/io/CreateIORequest.c -I~/dev/kernel_amiga/rom/includes -fpch-preprocess -v -dD -E

Thanks !

I have neither experience with CMake nor with CLion, but did you try to execute the command in a shell to find out why it fails? It will certainly give you a helpful error message.

From a quick look at the command line given I would say that -xc and -fpch-preprocess are no valid vbcc options.

Hi Phx,

The problem is that thoses parameters are automagically added by CLion not by me...

My idea is to adapt a working project to CLion

I created a project here https://github.com/skeetor/amiga-utils where I integrated gcc and vasm into a cmake compiler. The relevant files can be found here: https://github.com/skeetor/amiga-uti...utilslib/CMake
I had to create a new "compiler" to make it work. The advantage is that the projectfiles are then rather small: Here is a sample how my CMake project file looks: https://github.com/skeetor/amiga-uti...CMakeLists.txt

Don't know if that will work easily with CLion, as I also didn't get it to work with my setup.

I'll have a look, thx

If you create your own cmake compiler you don't need that enable language part, as C/CPP files are known anyway. You still have to create an appropriate VBCC compiler though, which tells cmake what options it needs to set.
If you get CLion to work, I would be interested in it, as I currently use Notepad++, but CLion is much nicer to use.

There is also some support for cmake with cross compiling https://gitlab.kitware.com/cmake/com...CrossCompiling so maybe this is also some help.

CLion works for me with gcc.

As an example see https://github.com/alexalkis/a68k/bl...CMakeLists.txt

My current project uses m68k GCC-6.4 too, but I can't compile the following code :

long toto(register long a __asm("d1")) { return a; }

I can't /don't know how to make gcc puts function parameters in registers...

That's why I want to use vbcc

The gcc prototype would be:

long toto(long a __asm("d1"));

That's how I've mixed C and assembly in my project.

If you don't care about the specific registers and just want to avoid passing on the stack, I think the -mregparm option is meant to do that.

Are you running CLion in Linux? I would assume that it might work there. On Windows I would liketo know how to set it up with MKSYS2 and the amigaos toolchain from bebbo.

I have done some work with CMake as well: https://github.com/AmigaPorts/AmigaC...ossToolchains/

I haven't added VBCC, but VASM support, because I needed it in a project.

This toolchain is used in the amigadev/crosstools:m68k-amigaos docker image. (source: https://github.com/AmigaPorts/docker-amiga-gcc/)

This contains all the compiler modules needed to enable VASM:

Sparhawk: I'll gladly work together with you to make this the ultimate Amiga CMake package, if you'd like.

That would be cool. My toolchain works for me, but I wouldn't be surprised if there is a more elegant approach. My goal was to ideally have only a minimum of setup steps in a cmake project, which means that I want only use find_package() and everything else is automatically properly configured.

My goal is to have an as much ready to go prebuilt environment for people to use with whichever Amiga flavor they want. Hence the docker.

My improvements are on all ends in the case of Docker:
* Environment variables set for CC, CXX, AR, LD, RANLIB etc,
* Aliases for m68k-amigaos-gcc to just gcc etc (so it's like how it would be when compiling directly on Amiga with a Makefile)
* using cmake, the m68k-amigaos.cmake toolchain file is preloaded and has all the required variables, so all you need to do is: mkdir build && cd build && cmake .. && make
* CMake modules for VASM is preinstalled in the proper directory so enable_language(ASM-VASM) works without extra tinkering

What could be improved is how the ASM-VASM files are setup, and adding VBCC as a C/C++ compiler variant.

I've sent an invite to be part of AmigaDev/AmigaPorts and granted you access to the AmigaCMakeToolchains repository.

Indeed this is on linux.

It works on beboo's gcc-6.5

Looking at the Docker files, this seems to only run on Linux though right?

I am currently converting a Sublime Text project into a CLion one (Sublime is nice but lacks the smarts of CLion) so I think I am going to give the latter (VBCC setup) a try.
At the moment I am building (on macOS) via a simple

build.sh

script but that is obviously not be scalable in the long run.

I am not a big CMake fan (to be polite ) but that will be better than nothing.

I would be interestd in a CLion project too
