In the age of AI tools like this are pointless. Especially new ones, given existence of make, cmake, premake and a bunch of others.

C++ build system, at the core, boils down to calling gcc foo.c -o foo.obj / link foo.obj foo.exe (please forgive if I got they syntax wrong).

Sure, you have more .c files, and you pass some flags but that's the core.

I've recently started a new C++ program from scratch.

What build system did I write?

I didn't. I told Claude:

"Write a bun typescript script build.ts that compiles the .cpp files with cl and creates foo.exe. Create release and debug builds, trigger release build with -release cmd-line flag".

And it did it in minutes and it worked. And I can expand it with similar instructions. I can ask for release build with all the sanitize flags and claude will add it.

The particulars don't matter. I could have asked for a makefile, or cmake file or ninja or a script written in python or in ruby or in Go or in rust. I just like using bun for scripting.

The point is that in the past I tried to learn cmake and good lord, it's days spent learning something that I'll spent 1 hr using.

It just doesn't make sense to learn any of those tools given that claude can give me working any build system in minutes.

It makes even less sense to create new build tools. Even if you create the most amazing tool, I would still choose spending a minute asking claude than spending days learning arbitrary syntax of a new tool.
