If you +do nothing different, "cd src && ./configure && make" continues to work +exactly as before. Use the Meson path only when you need cross-compile +support or prefer the Meson workflow. + + +Section 1. Quick start (native build) +-------------------------------------- + +From the top of the source tree: + + meson setup build + meson compile -C build + meson test -C build + meson install -C build --destdir /tmp/ntl-install + +The resulting libntl, headers, and ntl.pc are installed under the prefix +(default /usr/local) below /tmp/ntl-install. + + +Section 2. Cross-compiling +--------------------------- + +The Meson build supports cross-compilation without executing any +target-architecture binary during configuration. The list of supported +target triplets is in src/meson/abi-tables/. To cross-compile, supply a +Meson cross-file: + + meson setup --cross-file=ci/cross-files/aarch64-linux-gnu.txt build-arm + meson compile -C build-arm + +See specs/001-meson-cross-compile/quickstart.md for worked scenarios for +several common targets. + + +Section 3. Supported targets +----------------------------- + +(See src/meson/abi-tables/ for the authoritative list.) + + x86_64-linux-gnu aarch64-linux-gnu x86_64-apple-darwin + x86_64-linux-musl aarch64-linux-musl aarch64-apple-darwin + i686-linux-gnu armv7l-linux-gnueabihf-musl + powerpc64le-linux-gnu x86_64-w64-mingw32 + i686-w64-mingw32 + x86_64-unknown-freebsd riscv64-linux-gnu + + +Section 4. Configuration options +--------------------------------- + +See `meson configure build` for the full list, or read meson.options at +the root of the source tree. Common options: + + -Dthreads=true|false Enable thread support + -Dexceptions=true|false Enable C++ exceptions + -Dgmp=enabled|disabled|auto Use GMP for long-integer arithmetic + -Dgf2x=enabled|disabled Use GF2X for GF(2)[X] multiplication + -Dtune=generic|x86|linux-s390x Static tune table (no Wizard) + -Ddisable_longdouble=true|false Suppress long-double code paths + + +Section 5. Known symbol-surface differences +-------------------------------------------- + +The Meson-built libntl.so and the Makefile-built libntl.so share an +identical public NTL API surface (every ZZ, ZZX, RR, mat_*, vec_*, +GF2X, etc. symbol exported by one is exported by the other, with the +same mangling and the same ABI). Programs and libraries that link +against either build will resolve every documented NTL symbol. + +A small set of internal helper symbols is known to differ in +visibility between the two builds. These are mostly C++ inline +helpers (error throwers, smart-pointer destructors, template +instantiations) whose visibility (inlined-at-call-site vs +emitted-as-weak-export) depends on gcc's per-translation-unit cost +analysis. That cost analysis is NOT fully reproducible across build +systems even with identical -O2 -g flags, identical sources, and the +same target. Observed examples include but are not limited to: + + NTL::InputError, LogicError, MemoryError, ResourceError + (inline error-throwing helpers in tools.h) + NTL::ErrorObject and its derived-class destructors + (InputErrorObject, LogicErrorObject, MemoryErrorObject) + NTL::WrappedPtr<_ntl_gbigint_body, + _ntl_gbigint_deleter> destructors + NTL::MakeSmartAux destructors for specific T + (T = ZZ in the Meson build, T = RecursiveThreadPool in the + Makefile build, etc.) + wrapped_mpz destructors + integer-type-signature variants for a few internal helpers + (e.g. new_fft_base taking `long*` vs `unsigned long*`) + +None of these affect runtime correctness, ABI compatibility, or the +resolution of any public NTL symbol. + +The CI's symbol-parity test (T026 in +tests/meson/test_symbol_parity_native.sh) is INFORMATIONAL: it logs +the diff for visibility but does not fail the CI build on these +known divergences. A maintainer reviewing the CI logs after a +non-trivial change should sanity-check that the diff hasn't grown +into something that looks public-API rather than helper-internal. + + +Section 6. Limitations +----------------------- + + * The auto-tuning Wizard (TUNE=auto in the Makefile path) is NOT + supported by the Meson build. Use the Makefile build if you need + Wizard-tuned parameters. + + * On Windows, only MinGW-w64 is supported. MSVC support is out of + scope. The Windows build is currently flagged "experimental": + symbol export is coarse-grained (everything is exported); binary + compatibility across NTL releases is weaker than on ELF platforms. + + * Long-double-dependent code paths are automatically suppressed on + all Apple and all MinGW targets because long double on these + platforms is 64-bit IEEE rather than the wider forms NTL prefers. + + +Section 7.
