ofxNetwork error in console (codeblocks windows)

mingw (windows)
#1

The udpReceiver and udpSender examples build and run fine, I can see the drawing between both apps.

On the receiver app, I get this console message every frame:

OF_ERROR: 298 unknown error: 0 see errno.h for description of the error

I searched for errno.h on my computer and it was here:
C:\Program Files\CodeBlocks\MinGW\include

but there is no 298.

Any idea what this error is?

(Windows XP, Codeblocks)

Thanks

#2

actually the errno is 0 not 298, 298 is the line in the file, but it shouldn’t be showing any message cause 0 is no error.

i’ve just fixed it in master

Hey Arturo

Will this version of the addon work with 0062?

https://github.com/openframeworks/openFrameworks/tree/master/addons/ofxNetwork/src

Or 007 only?

I don’t want to break my 0062 code. Perhaps you could tell me where you fixed the errno 0 in the code so I can just do to existing addon if not?

Thanks

To answer my own question, the version of ofxNetwork off github doesn’t work with 0062, I get these errors

If I comment out the switch case within ofxNetworkCheckErrno i then get these errors…

ah forget me, the version for 007 works. my github version was a few days old. just changing ofThread to ofxThread works.

Hi, arturo and chrisoshea

I got a similar error with OF 0.9.0, windows10.

[ error ] ofxNetwork: ..¥..¥..¥addons¥ofxNetwork¥src¥ofxUDPManager.cpp: 336 unknown error: 10035 see errno.h for description of the error

This error appears only on release mode, when it received no data.

Any idea what this error is?

Thanks

#7

there’s a couple of bugs in ofxNetwork in 0.9. they are fixed already in the nightly builds, can you try if that works for you?

#8

I’ve tried latest verson of ofxNetwork from GitHub, and it works!!

Thanks!

#9

I’m having a similar issue. Could you confirm if the Nightly build v20151109 is the one with the fix?
