error in ./installLibrealsense.sh

[elijah4rain]

I am installing R200 in Ubuntu 14.04 Jetson TK1 (armhf) with Kernel 3.10.40.

I followed all the tutorial and an error occurs in running ./installLibrealsense.sh The bottom shows the outputs when running each line from ~/installLibrealsense/installLibrealsense.sh

ubuntu@tegra-ubuntu:~/librealsense$ git checkout v0.9.2
M   librealsense.qtcreator/realsense.pro
M   src/uvc-v4l2.cpp
HEAD is now at c5d6b82... Merge pull request #236 from mdhorn/add-udev-debian

when I run the line patch -p 1 -i ~/installLibrealsense/arm.patch I pressed enter key at every question

sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
sudo cp config/uvc.conf /etc/modprobe.d/
sudo udevadm control --reload-rules && udevadm trigger

These three lines had no outputs

and finally, an error when executing 'make'

Thanks in advance!

Which version of L4T are you using?

[elijah4rain]

I thought that following the tutorial will lead to L4T 21.4 but do you recommend me to install specific jetpack before I install librealsense? I found your another tutorial about installing jetpack 2.0 on jetson tk1 and was wondering if that would suffice

[jetsonhacks]

JetPack installs L4T, as I recall JetPack 2.0 installs L4T 21.4. Your error messages above suggest that you do not have libusb installed. That is installed in the installLibrealsense script. I could not tell if you manually installed everything, or whether you ran the script once and then tried to reinstall things again. The error messages suggest the latter.

[elijah4rain]

Yes, I ran the script once and tried again line by line to see where the error occured. I don't recall if I installed jetpack so I will try to install jetpack 2.0 and try again. Thank you for your timely reply and I will update on this

[jetsonhacks]

One of the issues appears to be that libusb was not installed. In the script, this is the line:

sudo apt-get install libusb-1.0-0-dev
