[iOS] EXC_BAD_ACCESS client.Call("ident.login")

[aogilvie]

Sample code:

mage::RPC client("game", "localhost:2000");

    //
    // MAGE works with JSON-RPC: so
    // we create variables for the request's
    // parameters as well as for the response
    //
    Json::Value auth;
    Json::Value user;

    //
    // When logging in, you will need to submit:
    //
    // 1. An engine name, provided to you by the server-side developer
    // 2. A username
    // 3. A password
    //
    auth["engineName"] = "cms";
    auth["credentials"]["username"] = "username";
    auth["credentials"]["password"] = "password";

    //
    // Login will return you a user and a session. We take the
    // session and set it as our own.
    //
    // Note: It is possible that you need to call a different login
    // method. If it is the case, you should still expect to receive
    // the same data structure as with the standard ident module.
    //
    try {
        user = client.Call("ident.login", auth);

    } catch (mage::MageRPCError e) {
        cerr << "Could not login, an RPC error has occurred: "  << e.what() << " (code " << e.code() << ")" << endl;
// CRASH HERE EXC_BAD_ACCESS ********
        return;
    } catch (mage::MageErrorMessage e) {
        cerr << "Login failed: "  << e.code() << endl;
        return;
    }

I see the correct error log Could not login, an RPC error has occurred: MAGE RPC error: Client connector error: : Could not connect to http://localhost:2000/game/jsonrpc (code -32003) the straight after app crashes with EXC_BAD_ACCESS.

Is this in a main function? If yes, then its likely missing return values; if not, I assume the return statements could be causing this perhaps?

Could you put your full code in a gist? This codes run if I wrap it in a main function and give return values:

You might also want to have a look at the updated https://github.com/mage/mage-sdk-cpp-cocos2dx example, it contains some information about what you need to make it work (the example uses callback, but you should still be able to get what you are trying to do here done anyway)

I'm not running in main.
I'm now running just the top line mage::RPC client("game", "localhost:2000"); nothing else, and getting EXC_BAD_ACCESS.
It was working a couple of weeks ago, since I pulled the latest develop branch it dies. I'll look though the commit history later.

You do need to add some linker option. Please have a look at the cocos2dx integration notes mentioned above to start with. The commit history there might be more helpful than the ones here as well

Could you put whatever code sample you have somewhere? How about we create you a mage/mage-sdk-cpp-ios repo?

@aogilvie Could you make your sample code available somewhere so that we may have a look?
