Raspberry Pi Fails on ofSystem (openFrameworks Core) error.

[bakercp]

OfSketch compiles on RPI and serves static content but WebSocket is closed prematurely. This may be due to an older version of poco, but more investigation is required.

[bakercp]

Will attempt to fix this with newer version of Poco.

This seems to be related to ofxHTTP. Funny thing is that the ofxHTTP and ofxJSONRPC examples run on RPI ...

[bakercp]

So, basically the situation is that everything compiles, but something is broken in the websocket communication. Perhaps the WebSocket frames are too big or something -- I'm not sure yet. I did just get this exception on the raspberry pi side, which is strange ....

[ error ] ServerWebSocketRouteHandler::handleRequest: exception: std::bad_alloc
[ error ] App::onWebSocketErrorEvent: Stop: 50

So, maybe that is a clue ...

I don't have access to an RPi at the moment, but can we confirm that the browsers on the Pi fully support websockets?

[bakercp]

Yeah, it works under other circumstances. I'm going to start injecting
logging info tonight to see if I can get it to reveal its mysteries ...

I have seen this error quite a few times in Chrome:

Uncaught TypeError: Cannot read property 'isTemplate' of undefined

I'm assuming that is a piece of javascript ... that perhaps is not being downloaded from the server or something?

[bakercp]

Alright I figured it out.

It all boils down to an error with ofSystem on Raspberry Pi. This is called during the connection routine when ofGetTargetPlatform() is called. This needs to be addressed in openFrameworks as an issue. For the moment I am going to try to create a hack so we can keep moving. You'll be happy to know as soon as I made my initial hack raspberry Pi worked splendidly (slow of course, but splendidly :)).

This should be fixed as of 73cf43d. !
