error adding physicssprite3d in a scene
i want to add a physicssprite3d in a scene. but it shows a weird error. (i think i did the physics3d setup wrong.)

(threed is the name of my class)

#include "physics3d/ccphysics3d.h"

// the following code is in the threed::createscene() function

auto scene = threed::createwithphysics();

scene->ge…
did you call initwithphysics() in your scene init() method?

there is a working demo in cpp-tests, so check that out and see what the differences are between that test code and yours.
you have to have freon added by a shop, i tried adding freon and it didnt work for me it has to be done by a special machine hi,

i can compile your code without error.

could you help to double check your makefile and environment?

environment is set by jetpack2.3.1

#include "nvx/nvx\_opencv\_interop.hpp"

#include <opencv2/imgproc/imgproc.hpp>

std::vector<cv::mat> tovisi… [@jbcousins92](/u/jbcousins92) i took a look at your repository and it looks like the course is expecting you to add the image in the \_includes/02-image.md file instead of the index.md file. can you try adding the same image there and letting the bot check it out? May be the function is executed before the document is ready.
Try to use document.ready function like this:



```
$( document ).ready(function() {
    $('#machines').change(function() {
        var $selected = $(this).find(':selected');
        $('#description').html($selected.data('description'));
    }).trigger('change');
});

``` hey [@aravindhrs](/u/aravindhrs) 
after checking the project-structure x-times i found my mistake. 
the processes.xml was created but not in the “meta-inf”-folder. after the correction of this the forms works perfectly. 
lessions learned: the problem sit 80cm in front of monitor. :wink: [image] cid\_cat:

error: c++11 is required and is missing or failed to compile.

i can’t help with most of that, but for c++11, see:

<https://gcc.gnu.org/projects/cxx-status.html#cxx11>

you probably must explicitly pass argument “-std=c++11” (or in some cases, perhaps “-std=gnu++11”).

if you l… if i get this right you are trying to sweep1 circle and have the sweeps come to a point.

if that be the case, you either need to have the sweep paths cross and go far enough past each other to come to a point (at right) or you can place the cross section on the inside of the sweep path rather than … > if( !@include( $path ) ) {
> 
> 


That part of the syntax is totally wrong. I don't think that an include is not meant to be in an if statement. Also replace the include with the require function which does the same thing but with error reporting. Also I would advice removing those @ symbols. So the above quote should be the following:



```
if(file_exists($path)) {
require( $path );
} else {
``` Hi Scott,

As you have mentioned that you have licensed an image accidentally, I have added an image credit to your account so that you can license a different image instead.

Hope that helps!

Feel free to reach out to us for any other issue.

Twarita I have the same problem and added this to the DbContext:



```
private void PrintStackTrace()
{
  var st = new StackTrace();
  foreach (var sf in st.GetFrames())
    Console.WriteLine($"{sf.GetMethod().DeclaringType.Assembly.GetName().Name} {sf.GetMethod().DeclaringType.Name} {sf.GetMethod().Name}");
}

```

and call this function in the contructor and Dispose of the DbContext.


It seems to be a problem, if the DbContext is added with scoped lifetime to the dependency injection. I filed an issue for that.
