# TOML config for NurOS package builder

# Self-build flags (apgbuild, apger) are hardcoded in Meson.build:

# This file only configures [build.packages] — flags for distro packages.

# ── Cross-compilation profiles ────────────────────────────────────────────────

# cc/cxx = "default" → clang/clang++ (best for cross-compilation)

#   - clang: --target=<triple> added to CFLAGS/CXXFLAGS/LDFLAGS

# Per-recipe override example (in recipe .toml):
#   [build.override]
#   cc = "clang"
#   opt_level = "O3"

[logging]
# verbose = true reduces log filtering during builds.

# true  = show more: configure checks, make internals, cmake status, notes
