ofxFenster : not compiling on osX

advanced
#1

Hi,
I’m giving some help to adapt ofxFenster to osx.
Has someone something about errors on (from the example)

  • NSObjCRuntime.h
  • Unknown type name ‘NSString’
  • Unknown type name ‘Protocol’

Help appreciated
Cheers

I usually see errors like this when I have a .cpp file that contains objective c / objective c++ code and I haven’t told xcode to compile it as objective-c++. files that mix objective c and c++ need to be compiled as objective c++, even if they are called .cpp. you can force a file like that via the sidebar in xcode, where for a specific file you can set the type

hope that helps!

Hi Zach that works,

Now I get a BAD ACCES error on the first line in main.

#4

Let’s see more details in this github thread

#5

I haven’t tried to compile it, so I’m just trying to debug on a napkin here, but it looks like maybe somewhere there needs to be a call to glfwInit () before you start calling glfw functions.

#6

hi, don’t know. I have it some times…
all’s almost clear, now

#7

I managed to get the example project working under of0.8 with xcode5 - ofZach was right, needed to set the following files to objective c instead of c++

ofxFensterManager.cpp and
ofxFenseter.cpp

I’m not seeing the"BAD ACCESS" @new_dudley is - I’ve created a PR but it seems @underdog is a bit snowed under (there are 2 other PR’s that have been waiting months) you can access it here for now - https://github.com/sheridanis/ofxFenster
