Electron 32 support

[Prinzhorn]

It's still in beta but I just happened to try to compile better-sqlite3. We're also not alone, e.g. xmppo/node-expat#230

> electron-rebuild --build-from-source -f -w better-sqlite3

[neoxpert]

Looks like AccessorGetterCallback has finally been removed from the api after having been marked as deprecated for some years now.

You can give it a try and change the c++ Standard from c++17 to c++ 20.

Also change the macro NODE_GETTER within macros.lzz from

#define NODE_GETTER(name) static void name(v8::Local<v8::String> _, const v8::PropertyCallbackInfo<v8::Value>& info)

to

#define NODE_GETTER(name) static void name(v8::Local<v8::Name> _, const v8::PropertyCallbackInfo<v8::Value>& info)

Also within macros.lzz replace AccessorGetterCallback with AccessorNameGetterCallback (2 occurrences).

[Prinzhorn]

With all your changes what's left is

/src/util/macros.lzz:169:28: error: ‘class v8::ObjectTemplate’ has no member named ‘SetAccessor’

[neoxpert]

Oh, yes. You might also replace SetAccessor with SetNativeDataProperty within macros.lzz.

[Prinzhorn]

It does indeed compile, thanks! Will you provide a PR in the future?

[neoxpert]

I actually already created a branch in my fork repo. But there are issues with setting c++20 option within the Ubuntu container, as it is not known by the used GCC / G++ version but named c++2a instead. Need to figure out how to adjust the build.yml and / or the bindings.gyp.

[Prinzhorn]

Fun fact I'm on Ubuntu (23.10), so I assume it's because the container is just outdated?

$ gcc --version
gcc (Ubuntu 13.2.0-4ubuntu3) 13.2.0

[neoxpert]

That seems to be the case. The runner-image documentation states that gcc 9.3.0 is preinstalled, which does not yet support the c++20 option. But newer versions already replaced the c++2a version with c++20, so using c++2a would cause issues :-/.

[neoxpert]

Well, the GCC and G++ where available within the Ubuntu 20 repo. I opened up a pull request.

[mceachen]

Thanks for the PR, @neoxpert ! #1226 just got merged.
