configure.ac enforces C17 and Linux/x86_64, refuses in-tree configure; Makefile.am builds libc.a plus crt0.o; the driver Makefile dispatches out-of-tree builds into bin/release (-O2) and bin/debug (-O0 -g).

# Driver Makefile — nulsl-libc

|
# This is the HAND-WRITTEN top-level makefile (committed to git). It never
|
|
# runs the autotools machinery in-tree; instead it drives two out-of-tree
|
|
# builds, one per bin/ directory, exactly as the Null Linux guidelines want:
|
|
#
|
|
# make release -> ./configure CFLAGS='-O2' into bin/release/
|
|
# make debug -> ./configure CFLAGS='-O0 -g' into bin/debug/
|
|
#
|
|
# Run `./autogen.sh` once after cloning (or just run `make release` — it
|
|
# regenerates the configure script itself when needed).
|
|
#
|
|
# Never run `./configure` at the repository root: configure.ac refuses it.
