Undefined C++ API symbols

[ashtonmeuser]

Describe the bug

Wasmer static lib does not seem to contain C++ symbols.

#include "wasm.hh"

inf main() {
  auto engine = wasm::Engine::make();
}

g++ -o src/mylib.os -c -std=c++17 -arch x86_64 -g -O3 -fPIC -I. -Iwasmer/include src/mylib.cpp
g++ -o mylib.dylib -arch x86_64 -framework Security -dynamiclib src/mylib.os wasmer/lib/libwasmer.a

Produces the following error.

Undefined symbols for architecture x86_64:
  "wasm::Config::make()", referenced from:
      ... in mylib.os
  "wasm::Config::~Config()", referenced from:
      ... in mylib.os
  "wasm::Config::operator delete(void*)", referenced from:
      ... in mylib.os
  "wasm::Engine::make(std::__1::unique_ptr<wasm::Config, std::__1::default_delete<wasm::Config> >&&)", referenced from:
      ... in mylib.os
  "wasm::Engine::~Engine()", referenced from:
      ... in mylib.os
  "wasm::Engine::operator delete(void*)", referenced from:
      ... in mylib.os
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

Steps to reproduce

1. Use Wasm C++ API e.g. wasm::Engine::make()
2. Compile
3. Link Wasmer lib

Expected behavior

Wasm C++ API is usable and symbols are defined in libwasmer.a.

Actual behavior

Wasm C++ symbols are undefined in libwasmer.a.

Thanks for letting us know about this @ashtonmeuser! This seems like a regression in what goes into our libwasmer.a. For the meantime, you should be able to use the C API.

I'd love this fixed too.

Alternatively, any chance someone could give me the gist of how these symbols should be produced? I'm happy to attempt a fix.
