Seg Faults after removing EasyCam

[bakercp]

I am thinking that ofEasyCam may be failing because we do not have ofEvents working correctly yet (to respond to mouse / keyboard input). I am working on this now over in another issue and hope to have it all working in the next few hours.

[danzeeeman]

also I think ofSetVerticalSync(true); might be causing a bunch of issues. I'm starting to comment it out of the examples I'm testing.

fyi (just added to piratepad (http://piratepad.net/jFNE528ols) but we may want to put this somewhere in a readme)

Debugging If your app is crashing (segmentation fault, etc) you can get better error messages/stack traces by using gdb

example (raspberrypi_helloWorldApp is your compiled app):

$ make Debug
$ cd bin
$ gdb raspberrypi_helloWorldApp

(type "r" to run)

Nice tip @jvcleave I'll make sure it is included when I move the pirate pad stuff over to this wiki.

[danzeeeman]

so I got this when trying to compile with make Debug

g++: error: ../../../libs/openFrameworksCompiled/lib/linuxarmv6l/libopenFrameworksDebug.a: No such file or directory make: *\ [bin/raspberrypi_debug] Error 1

forgot to mention you have to make debug OF as well

Right now, the make only makes release libs. Did you explictly do a 'make Debug' for the core libs?

[danzeeeman]

I didn't run a make debug on the openFrameworksCompiled/project

We're all on the same page :)

with gdb enabled:

this looks like its fun

[danzeeeman]

looks like the culprit is: mesh.draw()

[danzeeeman]

so in ofMesh the draw() function we grab the renderer from ofGraphics and call draw but I'm not sure if we are returning the correct renderer for the rpi.

[bakercp]

Can you check the getType() string? It should be ofGLRenderer (we aren't using the GLES type). IF it's null that's also a problem.

[bakercp]

hey dan, could you give a little more info on how you got this example running.

i rebuilt my core libs, and removed the GLUT specific stuff from the example main.cpp then ran make, but got this:

terminate called after throwing an instance of 'Poco::SystemException' what(): System exception Aborted

Did you may any other modifications besides uncommenting the bcm_host line in ofConstants?

[danzeeeman]

I'll push the whole project. I'll make an ofxRaspberryPi examples folder in examples/addons and push updated examples there. On Nov 21, 2012 8:52 AM, "Christopher Baker" notifications@github.com wrote:

I pushed the examples but I screwed up and checked in updates to the raspberrypi devApps that I changed. grrrrrr command line git errors.

Perfect.
