Build issues w/ VS2010

[gazoakley]

Hi,

I'm having problems building any of the examples or any projects created from the Project Generator that use ofxLibwebsockets. I'm always getting the following error:

openFrameworks itself builds without any errors

After further investigation, I found an empty time.h file in ofxLibwebsockets\libs\libwebsockets\include\win32port\win32helpers\sys. Deleting it and excluding it from the project seems to allow the .cpp files to build successfully, although there are then a bunch of linker errors:

Any ideas?

[robotconscience]

Can you check out the repo now and try again? Just merged in the dev branch, where I rebuilt the VS projects + the libwebsockets lib on windows. Should be good-to-go!

Let me know if you still have issues after using the new branch.

[robotconscience]

P.S. I moved away from the auto-gen projects in the end, as they don't do any of the library linking for you (why you are seeing the build errors).

Hi Brett - thanks for the quick reply! 👍

I can't see any updates to the *.vcxproj files since the original commits in:

https://github.com/labatrockwell/ofxLibwebsockets/blob/dev/example-server-echo/example-server-echo.sln

Looking for the changes in dev here:

https://github.com/labatrockwell/ofxLibwebsockets/tree/dev/example-server-echo

Am I looking in the wrong place?

[robotconscience]

Shoot, you're right, I must not have committed the projects. Give me just a little bit, will push them up shortly. Sorry about that!

[robotconscience]

OK! pull now, should be fixed... I don't have my Windows machine with me, so I just fixed them in a text editor. Fingers crossed I caught the problems!

Hi Brett,

Looking much better now - thanks! 👍

[robotconscience]

Great! Closing this issue for now, please re-open if you have more problems!
