Binding to a class throws an exception about quickjspp HOT 6 CLOSED

Are you using JS_NewContext2? It might be that js class "Object" isn't registered. Try to add JS_AddIntrinsicBaseObjects(ctx); and see if the error persists

from quickjspp.

Shot in the dark, but perhaps its because you arent registering a constructor for that class? Try:

module.class_<Coord>("Coord")
  .constructor<your, types, here>();

Thanks for the responses. Appreciated.

Ftk, I am not using any of the JS_ methods directly - just calling the quickjspp wrapper code. Where would I call JS_AddIntrinsicBaseObjects?

Sam, my original code had a constructor appended but is throwing the exception before even getting to that :) I removed it for clarity.

Could it be how I have compiled quickjs? I am compiling for x64 on windows, so have used a fork of quickjs for msvc. Are there specific flags I should be compiling with. I just tried this simple example:

qjs::Runtime* runtime = new qjs::Runtime();
qjs::Context* context = new qjs::Context( *runtime );
context->eval( "let a = 127; a--;" );

Which throws the following JS exception (quickjs.c, JS_ThrowError) eval is not supported

from quickjspp.

I have no idea what is happening. All the arguments I am passing in to the quickjs code are being mangled and have different values inside the JS_ methods themselves. It has to be something related to how quickjs.lib was compiled, or how it is linked into my app. Example:

JSRuntime* rtx = JS_NewRuntime();
JSContext* ctx = JS_NewContext( rtx );

string code = "let a = 123; a--;";
JS_Eval( ctx, code.c_str(), code.length(), "<eval>", 0 );

Inside JS_Eval, the last argument, 0, has come through as a huge value (changes every time). In fact the values of all 5 arguments are different every time I run/debug.

Are you using quickjs.h from the forked quickjs? Also, depending on compile options sizeof(JSValue) can have different size which results in this strange behavior.

ftk, you were right on the money.
I was compiling quickjs with the following flags: JS_STRICT_NAN_BOXING, CONFIG_BIGNUM, CONFIG_JSX, CONFIG_STORAGE
However, I was not defining these same flags in my application before including quickjspp.h.
I have changed it to the following, and now it is working fine:

#define JS_STRICT_NAN_BOXING
#define CONFIG_BIGNUM
#define CONFIG_JSX
#define CONFIG_STORAGE
#include "quickjspp.hpp"

Thanks so much for your help!
