Compile Issues

[bringsz]

I'm seeing a lot of people having various problems compiling the sources.

I've already followed several tutorials to resolve 'io_service' errors.

I'm using this server.

After adding the /utf-8 command in C/C++ because it was giving a Unicode error, it's now giving this error.

Edit:
Windows 10 - Visual Studio 2019

I've already tried doing that and nothing works.

change all fmt::format("{}", action) to fmt::format("{}", static_cast<int>(action))

and all fmt::format("{}", state) to fmt::format("{}", static_cast<int>(state))

If this not works change fmt version maybe.



You can also make new file src/fmt_extensions.h

#pragma once
#include <fmt/format.h>
#include "iomarket.h" // albo gdzie masz MarketAction_t / MarketOfferState_t

template <>
struct fmt::formatter<MarketAction_t> : fmt::formatter<string_view> {
    auto format(MarketAction_t action, fmt::format_context& ctx) {
        string_view name = "UNKNOWN";

        switch(action) {
            case MARKETACTION_BUY:  name = "BUY"; break;
            case MARKETACTION_SELL: name = "SELL"; break;
        }

        return fmt::formatter<string_view>::format(name, ctx);
    }
};

template <>
struct fmt::formatter<MarketOfferState_t> : fmt::formatter<string_view> {
    auto format(MarketOfferState_t state, fmt::format_context& ctx) {
        string_view name = "UNKNOWN";

        switch(state) {
            case OFFERSTATE_ACTIVE:    name = "ACTIVE"; break;
            case OFFERSTATE_CANCELLED: name = "CANCELLED"; break;
            case OFFERSTATE_EXPIRED:   name = "EXPIRED"; break;
        }

        return fmt::formatter<string_view>::format(name, ctx);
    }
};

Then open: iomarket.cpp and add #include "fmt_extensions.h"
