PPA samples not working on ubuntu

[nvoelzow]

after installing the sdk through the PPA as mentioned in the docs on a fresh ubuntu 18.04.3, all of the "get_" and "camera_" samples will crash except get_device_info and get_imu_params:

Hi, Please uninstall SDK complied with source code before install PPA.

[nvoelzow]

just tried starting with a fresh 18.04.3 install and then following the guide, the problem remains the same:

$ sudo add-apt-repository ppa:slightech/mynt-eye-s-sdk
$ sudo apt-get update
$ sudo apt-get install mynt-eye-s-sdk
$ cd /opt/mynt-eye-s-sdk/samples
$ ./camera_with_junior_device_api 
I/utils.cc:35 Detecting MYNT EYE devices
Illegal instruction (core dumped)
$ ./camera_with_senior_api 
I/utils.cc:35 Detecting MYNT EYE devices
Illegal instruction (core dumped)

just to check the opencv version:

$ apt list | grep opencv

Hi, we have checked on fresh 18.04.3 too, seems like no problem, you could try with sudo command.

[nvoelzow]

same thing with sudo, all sample applications crash with the same error:

$ sudo ./get_device_info 
I/utils.cc:35 Detecting MYNT EYE devices
Illegal instruction

and when running in gdb:

(gdb) run

The camera is showing up in lsusb as two uvcvideo devices (creating /dev/video0 and /dev/video1):

opening /dev/video0 in xawtv or vlc works by the way, giving me a green-purple overlay image of the two camera views.

[harjeb]

Hi could you try ls /usr/local/lib | grep mynt

[fukamike]

I have same problem.
I tried ls /usr/local/lib | grep mynt
but no massage.

[fukamike]

I using ubuntu 18.04.3 .
I tried samples.
$ cd /opt/mynt-eye-s-sdk/samples $ ./camera_with_junior_device_api
the result is I/utils.cc:35 Detecting MYNT EYE devices Illegal instruction (core dumped)

[harjeb]

@fukamike Hi, which model do you use？ ls /usr/local/lib | grep mynt is used to check .so file compiled by source code.

[fukamike]

I'm using EYE s1030

[harjeb]

@fukamike Could you use source code to compile? we don't meet this issue on our environment(18.04.3 64-bit PC with USB3.0 interface).

[fukamike]

@harjeb I was able to compile source code and run sample code.

[fukamike]

If I want to develop codes, Should I change sample codes?
For example get_stereo_rectified.cc ..etc.

[harjeb]

Yes, you can change sample codes or follow the demo project to create a new one.

[simonegodio1994]

@fukamike Excuse me I have the same problem.. did you succeed to make it works also the IMU? Can you please share it?

Thank you in advance!
