current status: writing a build system in cmake

cmake with classes
-
to be clear i'm not doing this because i love writing cmake syntax that would drive mere mortals mad. i do it because i'm replacing a "simple Makefile" that has perhaps once fit that bill, but eventually turned into a 1200-line (not including *.inc files) monstrosity with a load-bearing rot13 call inside of a manual reimplementation of half of
git submodule(this particular monstrosity has since been removed but the overall genre has not changed)
@whitequark ah, the fingerprints of an engineer who is very capable, but doesn’t bother to read the docs or think about alternatives…
I’ve reimplemented a git LFS client without knowing that’s what I was doing. -
@whitequark I mean very minimal. Like it fetched the bits I needed. “God, why are these binary files just a sha hash? Oh, and there are files over here with those hashes as names, fine, let’s do this.”

@whitequark self-awareness is not always online

current status: writing a build system in cmake
not "something that builds a project and is also implemented in implemented in cmake"
no, it is "something that is implemented in cmake and can be used to implement a build system that is in turn used as a part of a build system (also in cmake)"
@whitequark I have described the Linux kernel's build system as "a build system implemented in GNU make," so, seems normal.
-
@pikhq @whitequark there are a lot of people for whom build systems are just not on their radar. I don’t understand them in the least, but I have definitely observed them in action.

@whitequark someone wrote a raytracer and PNG encoder in CMake sooo

The world of buildsystems is weird and fascinating.
My opinion on cmake is that (for certain domains) it's the best there is, and that's sad.
@asmw @whitequark to some extent, cmake is a natural consequence of the fact that every platform is almost actively hostile to the idea that 3rd party developers also target other platforms
-
i'm making it sound more complicated than it is, the actual thing boils down to "cmake's dependency resolution algorithm doesn't work for a particular edge case i'm having, so i'm implementing a different one, in cmake script"
but also "dependency resolution algorithm" is basically what a build system is, so,
@whitequark
Having called out to tsort from a GNUmakefile to order library builds, I'm taking emotional damage from this thread. -
What happens if we remove all the abstractions? That will make everything simpler!
