make Error

[hayoonko]

hi, thanks you for your source code.

i try to make it, but /usr/bin/ld: cannot find -l64 error.

what is -l64? please help me !

[derzu]

Hi, I'm not sure, are you compiling on a Linux, is it 64 bits?

Send me the full make output.

Best regards,

Derzu.

[hayoonko]

yes, my os is both of ubuntu 16.04 and 14.04.

so i have trouble in ubuntu 16.04, but i change my os on ubuntu 14.04.

and another problem is
image@image:~/xtion2/BodySkeletonTracker/Bin/x64-Release$ ./BodySkeletonTracker
main::Compiled with Depth
Couldn't open device
DeviceOpen using default: no devices found

Compiled with Depth

thanks you for your reply.

The depth camera was not detected.

Are you testing with a depth device like Orbbec Astra, or Asus Xtion, or Primesense? Did you installed the OpenNI2 driver?

[hayoonko]

yes,

i used Asus Xtion2. i installed OpenNI2 driver and then test SImpleViewer.
not problem....

[derzu]

Did you run the source command?
$ source ~/Downloads/OpenNI-Linux-x64-2.3/OpenNIDevEnvironment (set your path appropriately)

[hayoonko]

of course.

i don't understand why occur this error...

[derzu]

At the main.ccp file try to change:
deviceURI = openni::ANY_DEVICE;
to
deviceURI = "/dev/yourdevice"

You need to discovery the /dev/ file of your device.

[hayoonko]

thanks you!

it work for me ! :)

but i try run
./BodySkeletonTracker
image@image:~/xtion2/BodySkeletonTracker/Bin/x64-Release$ ./BodySkeletonTracker
main::Compiled with Depth
Video Camera at /dev/video1 Detected
Depth Camera at /dev/video0 Detected

and then nothing happened ... (ex . any GUI)

[derzu]

Do you have any traditional webcam attached? If you are running at a notebook probably it will have a webcam. And webcam can be the /dev/video0. You said the SimpleViewer works for you, you can try to print the device string at it's code and verify if it is really the /dev/vide0 that is being used.

[hayoonko]

I am sorry that the answer is late. Currently my main.cpp is like this:
#include "SampleViewer.h"

int main(int argc, char** argv)
{
#ifdef DEPTH
int rc = openni::STATUS_OK;
const char* deviceURI = "/dev/ASUS-depth" ;
#else
int rc = 1;
const char* deviceURI = NULL;
#endif

#ifdef DEPTH
printf("main::Compiled with Depth\n");
#else
printf("main::Compiled witout Depth\n");
#endif

/*if (argc > 1)
{
	deviceURI = argv[1];
}*/
SampleViewer sampleViewer("Body Skeleton Tracker", "/dev/ASUS-depth");
rc = sampleViewer.init();

#ifdef DEPTH
if (rc != openni::STATUS_OK)
#else
if (rc != 0)
#endif
{
return 1;
}
sampleViewer.run();
}

I am using an xtion2 camera and the output of $ ls / dev / video * is like this:
image@image:~$ ls /dev/video*
/dev/video0 /dev/video1

Here is the output of $ ls / dev / *.

Video Camera at /dev/video1 Detected
Depth Camera at /dev/video0 Detected

No video frame will appear on the output screen.
I don't know why this problem occured.

[derzu]

I don't know what is the problem, maybe some driver issue, you can try to reinstall the OpenNI2 driver.

I think the best set for the deviceURI is:
const char* deviceURI = openni::ANY_DEVICE;

Because of this way the initOpenNI() method try to find the correct device.
