Hi,

Can you show how you define BinaryType? Because the error
you are receiving is related to serialization/deserialization process.

Best Regards,
Igor

Hi Igniters,

finally, I've compiled my code and run my test. But after I call my closure I got this errors: "Operation cannot be performed in raw mode.", and unfortunally I've no idea what it does mean.

This is the code of call:

IgniteConfiguration cfg;
std::string home = getenv("IGNITE_HOME");
fs::path cfg_path = fs::path(home) / "platforms" / "cpp" / "client_config.xml";
cfg.springCfgPath = cfg_path.string();

ignite = Ignition::Start(cfg);

IgniteBinding binding = ignite.GetBinding();
binding.RegisterComputeFunc<Calculation>();

Compute compute = ignite.GetCompute();

[...]

Calculation functor(name, args, false);
auto fut = compute.CallAsync<std::string>(functor);

[...]

And Calculation is:

class CalculationEngineIgniteServer: public ignite::compute::ComputeFunc<std::string>
{
friend struct ignite::binary::BinaryType<CalculationEngineIgniteServer>;
public:
CalculationEngineIgniteServer(
) = default;
CalculationEngineIgniteServer(
const std::string &name,
const std::vector<std::string> &input,
bool localLog
);

virtual std::string Call();

private:
std::string name_;
bool local_log_;

std::vector<std::string> input_;
};

Then I defined BinaryType for Calculation and for std::vector<std::string>. I don't understand where I miss.

Thanks,
F.D.
