ctime issues in VS10 #4

Closed j3ffgray closed 11 years ago

j3ffgray commented 11 years ago

Trying to port over an Xcode project to VS10 using this library, and I'm running into a bunch of ctime errors. It also appears to be happening when I try running the examples as well. A dump of the errors is below, any ideas?

Hey grayfuse,

I've run into this error, too. Unfortunately not in front of a PC right now, but can check tomorrow. In the meantime, can you check the additional include directories?

There was an error in the older projects where I was including every directory in ofxLibwebsockets. The one of note is ......\addons\ofxLibwebsockets\libs\libwebsockets\include\win32port. Make sure that there aren't any subdirectories there (e.g. ......\addons\ofxLibwebsockets\libs\libwebsockets\include\win32port\win32helpers, ......\addons\ofxLibwebsockets\libs\libwebsockets\include\win32port\win32helpers\sys)

Let me know if that works! Again, will double check tomorrow AM.

Well, that helped with the ctime issues. Getting a bunch of unresolved external symbols now. I'll keep digging around, but let me know if you've ever run into this.

yes, it looks like the libwebsockets libs aren't being linked in correctly. First, you need to add the ofxLibwebsockets paths to the "Additional Library Directories":

Apologies if the example projects are messed up! I'm using ofxLws in a Windows-based install right now, so I'll be updating everything to work much better ASAP!

j3ffgray commented 11 years ago

That did the trick, thanks! The documentation for manually setting linker settings and includes in Visual C++ for openFrameworks is very stark (especially since they are moving towards having people just use the projectGenerator), so this is very helpful in general since I'm usually strictly in Xcode. Thanks a bunch, and thats for a great WebSocket wrapper addon! :)
