Tutorial Part 2. error: no matching constructor for initalization of 'eosio::action'

[ajose01]

First off, as others have said... the tutorial is A++. Thanks 🙏 . I've tried to debug this on my own w/o much luck. I may just be overlooking something obvious, since I don't see others running into this issue. When trying to generate the ABI I hit this:

Marketplace.hpp:

#include <eosiolib/eosio.hpp>
#include <eosiolib/print.hpp>
#include <string>

Marketplace.cpp:

#include "Marketplace.hpp"
#include <eosiolib/asset.hpp>

namespace Oasis {
  void Marketplace::buy(account_name buyer, uint64_t productId) {
    productIndex products(_self, _self);

    auto iterator = products.find(productId);
    eosio_assert(iterator != products.end(), "The product was not found");

    auto product = products.get(productId);
    eosio_assert(product.quantity > 0, "The product is out of stock");

    asset productPrice = asset(product.price, string_to_symbol(4, "OAS"));

    action(vector<permission_level>(), N(anorak), N(transfer), make_tuple(buyer, _self, productPrice, string(""))).send();

    action(vector<permission_level>(), N(anorak), N(additem), make_tuple(buyer,
      product.product_id,
      product.name,
      product.power,
      product.health,
      product.ability,
      product.level_up 
    )).send();

    update(buyer, product.product_id, -1);
  };

Thanks for any clues.

Hi ajose01! Do you have the eosiolib inside the contracts folder? action.hpp is placed there.

[ajose01]

Thanks for the reply. I do have it in there, and can confirm that action.hpp is in there as well. It might be an EOS version thing?

For example... I get the same error even when trying to process an ABI from a gitclone of this repo.

I cloned the repo and I was able to generate the Marketplace.abi. Which version of EOSIO you're using? Can you try to rebuild the EOSIO with clean installation?
