Using make on OS X (and failing)

advanced
#1

Hello all,
I’m working on an app for ARM linux/NVidia Jeston, but prefer to develop on OS X.
I’d like to use make, like I do on linux and avoid XCode anything.

I’m getting these iphone simulator warnings on OS X from a project that works on Linux and Linux Arm; as well as the ofGstVideoUtils and some midi related errors:

make: *** [Release] Error 2

An ideas why?

#2

check midiIn example you have to extend the ofApp class like this

class ofApp : public ofBaseApp, public ofxMidiListener {
#3

I’m already doing that…

#4

maybe there are still some artefacts from previous builds.

  • make clean
  • or maybe delete the .obj directory, and those within the addons

To use this in OSX you have to use this addon

and install the GStreamer too.

this is only a warning but already fixed on nightly builds / git

#6

I think the make clean may have solved my midi related errors.

The gstreamer issue did not goin away with installing the ofxGStreamer addon; seems that @arturo 's addon may be a bit old, or maybe the failing build reported but github there is an issue?

I just #ifdef 'ed the linux specific parts that needed the gstreamer setup and I can now build…

#7

Does it build with xcode? That addon is a bit old but still works perfectly for me.

#8

Just to be sure, did you install Gstreamer on macOs? different from linux you have to install. There is a script inside ofxGStreamer addon with the install, but you can choose newer versions too (not sure if they are compatible with the addon)

#9

Yes; definitely have gstreamer (installed with homebrew) and can use it in the terminal.

#10

are you using ofGstVideoUtils directly?
if yes how are you including the file in your project? which file has the include?
