Serenity: Tracking: CMake Build

[bgianfo]

I wanted to start a discussion for what's left in terms of work for your experimental CMake port of the build system.
I'm willing to help out / improve the state of affairs, as I'm a bit frustrated with the current state of things.

[awesomekling]

The cmake_experiment branch is as far as I got. It's pretty old at this point but nothing has really changed other than files and directories being added in various places.

The last issue I remember struggling with was getting it to build crt0.o in LibC before everything else since nothing can build without it.

Someone who is comfortable with CMake could probably pick up the branch and make it work. I'm sure it can be greatly simplified as well.

I'm going to (attempt) to work on this. I've already got LibC/crt0 stuff sorted out.

I've now successfully built a bunch of libraries and an executable (the Shell):

[ 48%] Linking CXX static library libc.a
[ 48%] Built target LibC
[ 49%] Built target LibM
[ 51%] Built target LibPthread
[ 72%] Built target LibCore
[ 87%] Built target LibGfx
[ 89%] Built target LibThread
[ 95%] Built target LibMarkdown
[ 96%] Built target LibPCIDB
[ 98%] Built target LibLine
[ 99%] Linking CXX executable Shell
[100%] Built target Shell

Getting the Shell to build meant figuring out the right way to make CMake actually pick up LibC/LibM and so on, but it works now.

Clean your source tree of the files produced by the old buildsystem. Like maybe checkout a version with the old buildsystem, run make clean, then go back to the new version.

Sorry for not responding sooner @bugaevc, It builds fine on OpenBSD with cmake 3.16.2 and ports gcc with a small patch.
