OSX Build Failing #14

Job Failure Summary

See failing job: https://github.com/GordonSmith/component-model-cpp/actions/runs/18194501364/job/51797087211 (ref: 72f9cda)

1. WASI SDK/Clang Dynamic Library Not Found

dyld: Library not loaded: @rpath/libclang-cpp.dylib
Referenced from: .../build/vcpkg_installed/arm64-osx/wasi-sdk/bin/clang-19
Reason: tried: .../lib/libclang-cpp.dylib (no such file)

• Solution: Ensure libclang-cpp.dylib is present in wasi-sdk/lib/. Reinstall WASI SDK or set DYLD_LIBRARY_PATH appropriately.

2. No Matching Constructor for cmcpp::InstanceContext

error: no matching constructor for initialization of 'cmcpp::InstanceContext'
candidate constructor ... not viable: requires 1 argument, but 3 were provided

• Solution: Add a constructor to InstanceContext matching the arguments provided, or fix instantiation to use correct arguments.

3. Constexpr Initialization Errors in traits.hpp

constexpr variable 'flat_types' must be initialized by a constant expression
static constexpr std::array<WasmValType, flat_types_len> flat_types = []() constexpr { ... }

• Solution: Refactor initialization so all expressions are compatible with C++17/20 constexpr rules. Avoid lambdas in constexpr context.

4. Template Deduction Failure for flatten

no matching function for call to 'flatten'
candidate template ignored: failed template argument deduction

• Solution: Explicitly specify template arguments, and ensure calls match the function signature in func.hpp.
