2168_vision_example's Issues

a few things

For some reason the program doesn't recognize the following commands:
cout
endl
setw
imshow

And it has a error with vcap.open(videoStreamAddress) saying:

Invalid arguments '
Candidates are:
bool open(const ? &)
bool open(int, int, int, double)
'


Sorry if I'm missing something obvious

Clarification of X11 instructions

Awesome repository!
We (3618 - Petoskey Paladins) have been able to follow all the instructions and can run the vision example on the roboRio.

Our stumbling block is X11 forwarding, as described on http://controls.team2168.org/
We've added the line
src/gz angstrom-base http://feeds.angstrom-distribution.org/feeds/next/ipk/eglibc/armv7a/base/
to the new /etc/opkg/angstrom-base-feed.conf file, ran opkg update, but when we invoked opkg install xauth we're told "Unknown package 'xauth'."

opkg search yields no 'auth' packages of any kind.

Any pointers on what might have been overlooked?

We're just trying to get a view into the processing to see the intermediate processing.

Thanks

Conflict with #include wpilib.h?

Hello and awesome vision example.
I'm able to compile ftp and run your code on the roborio fine.
Now I'm looking at taking the example Arcade Drive and adding in the include/lib references and am having a issue.
First, I am able to build and run the Arcade Drive example,
I've added to it:
#include <opencv2/opencv.hpp>
using namespace cv;
I added _Includes\OpenCV\2.4.10 to the includes under paths and symbols in c++ general
I also added _Libraries\softFP\lib_OpenCV and lib_cpp to the library paths and
I also added the opencv_highgui,opencv_core,opencv_imgproc to the libraries list

When I compile, it appears there is a conflict between wpilib.h and opencv.hpp I get tons of redeclaration errors... Here is a sample:
Note there are lots of these, I've only added 4...Below them is the full code, Its not long.
Thanks for any help!
Eric
