Linker-Error

[bennigraf]

Hi again :-)!

I'm trying to run example-all and it finally builds, but throws an error when linking (see below). Does this have anything to do with ofxKinect? I don't know where to look for _write_register etc. at all.

I'm working on the most recent of master from github, just as all additional libs are cloned from there.

Thanks, Benni.

yes it seems an error linking ofxKinect, are you using the latest PG the one in 0.8.1? Also perhaps it's easier to start with video-audio example, and see if that works.

[bennigraf]

The video-audio-example is giving me "libusb-1.0/libusb.h file not found" in ofxKinect/libs/libfreenect/src/keep_alive.c. There is libusb-1.0/ in ofxKinect/libs though.

Sorry I have to ask, but what do you mean by PG?

[arturoc]

:) the project generator, you should regenerate the projects, the ones in the repo if there are some, are probably outdated

[bennigraf]

Thanks :-). Do you mean create a new project including all the necessary addons and add the source files of the examples manually? Doing so I get "agent.h: 'glib-object.h' file not found", even though I added the GStreamer-Framework (also manually) to the project.

[sethismyfriend]

Even though I set everything in my project to 32 bit only I am still getting this error: Undefined symbols for architecture i386:
"_write_register", referenced from:
_freenect_stop_depth in cameras.o
_freenect_stop_video in cameras.o
ld: symbol(s) not found for architecture i386
clang: error: linker command failed with exit code 1 (use -v to see invocation)

I'm pretty sure its something to do with the build settings of the project - I'll try updating the project generator but I think it's weird that I'm getting this error when we had the same settings in previous projects.

I have the same problem, glib-object.h "not found" (using latest PG and 0.8.1). By the way, the link to the nightly builds seems broken (http://openframeworks.cc/versions/nightly/of_latest_osx_nightly.zip)

[arturoc]

i think the paths to frameworks have changed with xcode 5 but i tested it some days ago and it was working for me without problem, i'll take a look on osx

[sethismyfriend]

Hey - Alvaro, awesome to see you are using the libraries. We are working on
a version where all the dependencies are linked as static libs and then the
current version for development to make it easy to setup and to keep up
with changes in the IDE. I have it working in XCode 5 on my Mac - one thing
to check is to make sure you have installed all the required dependencies
on your system in the /Library/Frameworks/GStreamer.framework/

Arturo, Seth!

Thanks for your answers! The libraries look amaaazing, but I could not
compile them yet.
I have been using ofxHTTP for some "teleprescence" project outside the lab
(I am trying to organize a dance event at a distance - actually Tango, I
mean real Tango, not the project Tango, haha - with some additional
minimalistic features to connect people), but XMPP seems very interesting
because of the metadata and the overlayed network (no static IP needed).

I'll keep trying, but any help is appreciated!
Hope everything is great,
Alvaro
