I am trying to compile this code:

#include <cstdio>

#include "requirements/jsapi.h"
#include "requirements/js/CompilationAndEvaluation.h"
#include "requirements/js/SourceText.h"

#include "requirements/boilerplate.h"

static bool ExecuteCodePrintResult(JSContext* cx, const char* code) {
  JS::CompileOptions options(cx);
  options.setFileAndLine("noname", 1);

  JS::SourceText<mozilla::Utf8Unit> source;
  if (!source.init(cx, code, strlen(code), JS::SourceOwnership::Borrowed)) {
    return false;
  }

  JS::RootedValue rval(cx);
  if (!JS::Evaluate(cx, options, source, &rval)) return false;

  // There are many ways to display an arbitrary value as a result. In this
  // case, we know that the value is an ASCII string because of the expression
  // that we executed, so we can just print the string directly.
  printf("%sn", JS_EncodeStringToASCII(cx, rval.toString()).get());
  return true;
}

static bool HelloExample(JSContext* cx) {
  JS::RootedObject global(cx, boilerplate::CreateGlobal(cx));
  if (!global) {
    return false;
  }

  JSAutoRealm ar(cx, global);

  // The 'js' delimiter is meaningless, but it's useful for marking C++ raw
  // strings semantically.
  return ExecuteCodePrintResult(cx, R"js(
    `hello world, it is ${new Date()}`
  )js");
}

int main(int argc, const char* argv[]) {
  if (!boilerplate::RunExample(HelloExample)) {
    return 1;
  }
  return 0;
}

Files compiled from “requirements/” are the same as the ones that the install puts in /usr/local. My goal is to get an executable, but instead I get the following in the command line:

The command I use is g++ test.cpp -o test -Wall -DDEBUG=1 and it gives some warnings (see above), and I should be getting an executable called test.

The problem isn’t obvious to me, and most of the resources online tell me nothing for my situation. The code I got is directly from “spidermonkey-embedding-examples” except I didn’t want to use the library in /usr/local, for a variety of stupid reasons I have to work with on my team.
