Hello, JetsonHacks. Thanks for your tutorials. And since I have fllowed your previous tutorials of realsense r200, and it works well. And I wonder would this tutorials influence the use of realsense r200? I may still need to use r200 sometimes.

Please checkout this quick pull request for pkg-config
https://github.com/jetsonhacks/buildLibrealsense2TX/pull/8

I have a similar issue to issue #12 but am unable to fix it (SOLVED-- see answer below). I am installing with CUDA 9.0 and the path to the compiler is in the usual location, /usr/local/cuda-9.0/bin/nvcc. The install with the script installLibrealsens.sh works fine without CUDA but fails when CUDA is selected.

The error is:
CMake Error at CMakeLists.txt:7 (project):
No CMAKE_CUDA_COMPILER could be found.
Tell CMake where to find the compiler by setting either the environment
variable "CUDACXX" or the CMake cache entry CMAKE_CUDA_COMPILER to the full
path to the compiler, or to the compiler name if it is in the PATH.

I tried to export CUDACXX as /usr/local/cuda-9.0/bin and also as /usr/local/cuda-9.0/bin/nvcc and also as nvcc
but none of those helped. The PATH also contains /usr/local/cuda-9.0/bin

I tried modifying the CMakeLists.txt file that is generated with the CUDA option off. I changed the CUDA option to ON and added this line to the CUDA section:
set(CMAKE_CUDA_COMPILER /usr/local/cuda-9.0/bin/nvcc)
but I don't know how to use that CMakeLists.txt file to drive a new compile. If I just use "make" it does not update the compilation.

UPDATE: It has to do with ownership. If I run installLibrealsens.sh without sudo, then it finds the CUDA compiler but fails with:

/usr/local/cuda-9.0/bin: Permission denied

If I run the script as sudo, either with or without the -E option to keep environment variables, then it cannot find the CUDA compiler.

ANSWERED:
put
CUDACXX=/usr/local/cuda-9.0/bin/nvcc
into /etc/environment so that it is applied when using sudo.

I hava built the realsense follow your sugestion, and install successfully
my steps:

1. flash os,install cuda
2. run script:getKernelSourcesNoGUI.sh from https://github.com/jetsonhacks/buildJetsonTX2Kernel
3. run ./installLibrealsense.sh
4. run sudo ./scripts/patchKernel.sh
5. run sudo ./scripts/configureKernel.sh

Hi!

I was following https://www.jetsonhacks.com/2018/04/09/intel-realsense-d400-librealsense2-nvidia-jetson-tx-dev-kits/ and did try to build the library with ./installLibrealsense.sh on a Jetson TX-2 and Ubuntu 18.04

I get the following errors:

Any idea on how to solve this?

Hey Jetsonhacks,

very nice that you take ont this challange!
Do you already know when this repo will be finished?

I am just starting with the D435 on the Jetson, is there already a way to get them both working together?

Cheers
Gustav

For me, buildPatchedKernel.sh silently exited because pkg-config --exists opencv returns an error and set -e.

CAN NOT get:
infrared 2, RGB Camera
TX2 CAN recognize the 3 cameras :

When enable 1 camera at once, can ONLY get the infrared 1 camera data, can NOT get either infrared 2 or RGB camera data (No Frames Received).
And there is a kind of ERROR backend-v4l2.cpp:1335 reported by realsense-viewer in terminator

When enable infrared 1 and infrared 2 at same time, neither of them can get frame

And I also tested with rs_capture ,

Basically the same time, I successfully install the librealsense2 in a TX2 with J120 carrier board In jetpack3.2.

My procedure as follow:

Flash the TX2 by using jetpack 3.2(with J120 USB patch, if you are using official board, just ignore)
Using jetpack3.0 to install CUDA8.0 and cudnn5.1
git clone https://github.com/freemanlo/librealsense
cd librealsense/scripts/
gedit patch-utils.sh
delete line 138
`sudo rm ${tgt_ko}.bckup`
save
sudo apt-get install libusb-1.0-0-dev pkg-config cmake git libglfw3-dev qtcreator cmake-curses-gui build-essential libgtk-3-dev libssd-dev
cd  ../
./scripts/patch-realsense-ubuntu-xenial-jetson-tx2.sh 
sudo cp config/99-realsense-libusb.rules /etc/udev/rules.d/
sudo udevadm control --reload-rules && udevadm trigger
install opencv by using https://github.com/jetsonhacks/buildOpenCVTX2 (ignore if you have already done that)
mkdir build && cd build
cmake ../ -DBUILD_EXAMPLES=true
make && sudo make install

some thread may help:

Install in Jetpack 3.2 (Intel provided an official patch script)
IntelRealSense/librealsense#1424

Install in Jetpack3.1
IntelRealSense/librealsense#1095 (I simply tested and some file can't be downloaded)

Best

I have TX2 and I just have installed up-to-date JetPack 4.2.2, L4T 32.2.1.
How can I install librealsense 2.25 instead of old 2.13?
what is the procedure? what does mean "Build and apply patched kernel modules"?
Do I need to run getKernelSources.sh from buildJetsonTX2Kernel at first and then patch it and only then install librealsense?
(https://github.com/jetsonhacks/buildJetsonTX2Kernel)

I need newer because I want to use t265 camera.

I am using TX2 with Auvidea j120 (jetpack 3.2.1) and trying to build librealsense2tx.
Whenever I try to build it, I got this.
Anyone can help?
Thanks in advance!

I have installed CUDA 8.0 on the Jetson Tx2 and am trying to install Librealsense using the jetson hacks script.
I can install the library fine without CUDA, but whenever I enable the CUDA flag, I am getting an issue that the CMAKE_CUDA_COMPILER flag is not found. I can compile other applications using CUDA just fine, but for some reason Librealsense cannot detect my version of CUDA. I've been trying to manually set the CMAKE_CUDA_COMPILER flag to /usr/bin/cc but that just throws another error during build.

I am using jetson hacks install Librealsense package for the installation, and updating the SDK version to 2.14.1 instead of 2.13.0. But both SDK versions return the same error for me.

as intel realsense also depends on librealsense2, could these scripts work for SR300? thanks all!

Hello,
when starting TX2 and testing roslaunch realsense2_camera rs_camera.launch, it works !

When i kill the node and start it again, SOMETIMES, IT FAILS,
and unable to restart node without restarting TX2 !!!

hello， i have a ZR300 camera, I followed this tutorials https://github.com/jetsonhacks/installLibrealsenseTX2 ,but I can only get image information, I can't get IMU information,please tell me does it support zr300?thanks!

hello, friends.
Tested some bin utils, doesn't work !!

My cam : d435
connected to small TX2, usb3 port, with a 4 ports unpowered hub.

Any idea ??
Thanks the team.

I ran the scripts with
./buildPatchedKernel.sh

sudo reboot 0

./installLibrealsense.sh

And when I try to run the example code (either rs-capture or realsense-viewer) on my tx2 I segfault and coredump.

Has anyone tried these scripts with Jetpack 3.3?
