The test file does #include <goldenfloat/gf16.hpp> but the cpp/include directory was not in the include path, causing a build failure. Closes #36
- Fix root Cargo.toml malformed cfg: cfg(unix(all(not(...)))) -> cfg(unix) - Add #include "gf16.h" to Go cgo preamble (was missing, all C names unresolved) - Add zig-out/bin to Python library search paths for CI compatibility
Closes #28 — replace goto-bus/setup-zig with mlugg/setup-zig in both test-bindings.yml and release.yml. Closes #35 — add #![allow(non_camel_case_types)] to goldenfloat-sys lib.rs for FFI-style type names. Closes #38 — GF16.fromF32 now maps NaN to exp=0x3F,mant=1 (not inf). GF16.toF32 returns std.math.nan when exp=0x3F and mant!=0. Closes #36 — add cpp/include to CMakeLists include_directories so <goldenfloat/gf16.hpp> resolves. Closes #37 — remove import "C" from gf16_test.go (Go forbids cgo in test files). Rewrite tests as exported Test* functions using the Go wrapper API from gf16.go.
…path - Rust ffi_example.rs: use .0 for UpperHex, inline bit extraction instead of missing GF16_SIGN/EXP/MANT macros - Go gf16.go: add #include "gf16.h", fix C type conversions (C.float/float32, C.bool/bool, C.uint16_t/Gf16) - C++: remove committed cpp/build/ from git, add to .gitignore, CI now rm -rf build before cmake - Python: add GOLDENFLOAT_LIB_DIR env var support - CI: set GOLDENFLOAT_LIB_DIR and LD_LIBRARY_PATH after zig build shared
The 'shared' named step depended on c_abi_lib.step (compile) instead of the install step returned by installArtifact(). This meant 'zig build shared' compiled the library but never copied it to zig-out/lib/, so all bindings failed to find it at link/runtime.
Implements IGLA-GF16 Module 1 from #3: - PHI, PHI_SQ, PHI_INV, PHI_INV_SQ, TRINITY constants - ALPHA_PHI = PHI - 1.5 = 0.118034 (matches alpha_s coupling) - Fibonacci sequence array (16 terms up to 987) - IGLA-GF16 architecture constants (d_model=144, n_heads=8, d_ffn=233) - Trinity weight init stds (gauge/higgs/lepton/cosmology sectors) - φ-LR schedule with warmup (Module 5) - 6 tests including Trinity Identity and architecture verification Part of #3
