A POC to test out a simple Hello World script, primarily focusing on SpiderMonkey ESR 115.

Prepping SpiderMonkey

The repo includes existing builds of SpiderMonkey (spidermonkey/include and spidermonkey/lib) against ESR 115.

If you do wish to build it yourself, then follow these steps:

• Do the prep work for Building Firefox
  • Don't worry about whether you use HG or Git
  • When bootstrapping, indicate you're looking to do a Spidermonkey build
  • Stop when you get to the build stage
• Follow the instructions for Building SpiderMonkey
  • Switch to the esr115 branch via hg up -C esr115
  • Look in spidermonkey/configs for debug and release configs that were/are used
  • When you're doing a build, use export MOZBUILD=/wherever/my/config/is

You should be good to go at this point.

Building with Visual Studio

To successfully build without altering any of the headers or anything, you will need to configure your Visual Studio to use the Platform clang-cl instead of v14x.

This requires the clang-cl Visual Studio installation option to be installed.

Open the solution and build as is - VS 2022 Community was used for setup.

Issues using v14x toolsets

Compile issues

enum JSProtoKey {
#define PROTOKEY_AND_INITIALIZER(name, clasp) JSProto_##name,
  JS_FOR_EACH_PROTOTYPE(PROTOKEY_AND_INITIALIZER)
#undef PROTOKEY_AND_INITIALIZER
      JSProto_LIMIT
};

The JSProto_LIMIT requires a , before it.

  ~LinkedList() {
#  ifdef DEBUG
    if (!isEmpty()) {
      MOZ_CRASH_UNSAFE_PRINTF(
          "%s has a buggy user: "
          "it should have removed all this list's elements before "
          "the list's destruction",
          __PRETTY_FUNCTION__);
    }
#  endif
  }

The __PRETTY_FUNCTION__ needs to be replaced (e.g. __FUNCSIG__)
