cmkr VS meson

Been using https://cmkr.build/ for a while now, its great and also declarative.

I would like to counter with a project I’ve been working on: https://cmkr.build. Unfortunately writing good CMake is extremely repetitive and there is definitely room for a generator that has sane defaults.

You are trying to use it the wrong way it seems, the point of CMakeLists.txt is that you only maintain that and nothing else. If you have changes in there then it will re-generate the project for you when it starts building. Adding files via IDE is not supported and is not really the point, there used to be a time where I primarily worked with VS solutions but the more I dove into the open source space the more it became clear that its the worst way of doing it. You just have to get used to a different workflow, the benefit is that your project can be in theory now compiled on all sorts of systems and not just with VS. If CMake is too much to handle perhaps give https://cmkr.build/ a try, it hides a lot of the CMake madness behind its toml specification, been using it for a while now, its great.

https://cmkr.build/ its pretty straight forward and been using it for some time now, can only highly recommend it.

Currently working on https://github.com/build-cpp/cmkr

I started working on https://github.com/build-cpp/cmkr to remedy this, but other similar solutions exist.

I invite you to take a look at https://github.com/build-cpp/cmkr, it makes this even easier ^

I’ve been working on cmkr, a modern build system based on CMake and TOML.

Definitely! I would recommend using cmake because it’s easy to generate a compile_commands.json. I’ve been working on https://build-cpp.github.io/cmkr to make the transition as smooth as possible.

As it happens, I recently landed a PR in meson to add a clang-like Weverything mode that includes all of that, so you can get a minimal list of more or less all GCC warnings, organized by version, from the meson source here: https://github.com/mesonbuild/meson/blob/710a753c78077220b13a9f7e999dcdb61339efb1/mesonbuild/compilers/mixins/gnu.py

Came here to post the same. The answer for How to build software? is Meson[1] for C and C++ and also other languages. Works well on Windows and Mac, too.

I’ve written a small Makefile to learn the basic and backgrounds. Make is fine. But the next high-level would have been Autotools, which is an intimidating and weird set of tools. Most new stuff written in C/C++ use now Meson and it feels sane.

If you are very fortunate, you'll be able to choose something else. I like meson myself: it looks a bit like python, it's popular, small, simple, well-documented, easy to install and update, and it works well everywhere.

I suggest changing the build tool. Meson improved C and C++ a lot:

The dependency declaration and auto-detection is nice. But the hidden extra is WrapDB, built-in package management (if wanted):

> C's only REAL problem (in my opinion) which is the lack of dependency management. Most everything else can be done with a makefile and a half decent editor.

Care to hear about our lord and saviour Meson?

Both of your quoted problems are mutually incompatible: dependency management isn't the job of the compiler, it's a job for the build or host system. If you want to keep writing makefiles, be prepared to write your own `wget` and `git` invocations to download subprojects.

Meanwhile, Meson solves the dependency management problem in a way that makes both developers and system integrators/distributions happy. It forces you to make a project that doesn't have broken inter-file or header dependency chains and cleans up all the clutter and cruft of a makefile written for any non-trivial project, while making it trivial to integrate other meson projects into your build, let other people integrate your project into theirs, and provides all of the toggles and environment variables distribution developers need to package your library properly. You can really have your cake and eat it too.

Other people going down this route seem to end up writing cmake replacements instead. I'm thinking of something like meson here except that meson never intended to transpile to cmake.

I thought I would share my custom installer script for the latest GitHub versions of CMake, Ninja, and Meson.
