- One toplevel Tupfile that makes it more clear what happens.
- Add config flags for -Werror, -fsanitize, and separate debug/optimize flags.
- Automatically integrate with libs built by CMake (build folder, rpath, libs folder).
- Disabling modules actually works, only the stuff that's needed is built.
It's still a rough draft and likely only works on my machine, but can be
improved over time.
Rough explanation:
- tup.config contains high-level build configuration defaults.
- Tuprules.tup contains mostly compiler flags (generated from the
tup.config) and declares some macros used to compile code.
- Tupfile takes all generated object files and links them into the
lovr executable.
- src/Tupdefault defines the default build steps for src and all
subdirectories, which is to compile all .c files to .o files and put
them in the <objects> bucket for linking by the toplevel Tupfile.
It's possible to have multiple configs active at once for different
platforms, projects, etc. To do this, create a folder for each build
variant you want, and place a tup.config in each folder (it can be a
symlink, which is helpful). Then, invoking `tup` will build all your
variants, or you can build a specific one by doing `tup <foldername>`.
