Installation HELP!! #12958
Comments
|
Hi @sai-srinivasan-v Could you first try unplugging the micro-sized end of the USB cable from the base of the L515 camera, reversing the connector's orientation and plugging it back into the camera, please (USB-C cables are two-way insertion at the micro-sized end). Does doing so make any difference? |
|
Hi @MartyG-RealSense I have done that. The camera is now being read when i enter 'lsusb'. Whats next? |
|
Is the camera also able to be read if you use the command If it is, can you then run the RealSense Viewer tool with the command |
|
'rs-enumerate-devices -s' returns No device detected. Is it plugged in? |
|
Thank you. Which method did you use to build the 2.47.0 SDK from source code? |
|
I cloned it from 'https://github.com/IntelRealSense/librealsense.git' and then |
|
If it was cloned from You would instead need to obtain the source code for version 2.54.2 or older from the SDK releases archive page as a .zip file at the link below and then extract the zipped librealsense folder and follow the same CMake installation process above from step 2 onwards. https://github.com/IntelRealSense/librealsense/releases Example programs and tools would be located in the usr/local/bin folder of Linux once the SDK has successfully been built. But to install them, you need to include certain flags in the CMake build instruction. I recommend the one below.
After that, use the sudo install command below:
A guide can be found at #9931 (comment) |

Hi @MartyG-RealSense I followed the guide and this is what i see. |
|
The -j value in the 'make' command, such as make -j8, can cause a random crash when building on some computing devices. You can test whether the j-value is the cause by leaving it out and just using 'make', though the SDK will take longer to build.
|
|
I tried. But i still see the errors or warnings scattered here and there is that ok? If so, what next? |
|
Thanks very much for your patience. As you are using kernel 6.8, does that mean that you are using the new Ubuntu 24.04? If you are using 24.04 then the most recent Ubuntu and kernel versions currently supported by the RealSense SDK are Ubuntu 22.04 and kernel 6.5. In theory, using the RSUSB = true installation method should mean that the SDK is not dependent on particular Linux versions or kernel versions. At the time of writing this though there have not yet been reports of other RealSense users using 24.04 and kernel 6.8, so it is not yet known if there is something in 24.04 that might cause problems with installation of the SDK. |
|
I also have a M2 Mac. Could you help me with that instead? @MartyG-RealSense |
|
Installation on an Apple Silicon Mac is currently more difficult than on Linux because RealSense cameras are having issues with recent MacOS versions such as Ventura and Sonoma (RealSense has not officially supported Mac since 2018). The last MacOS version that RealSense has been able to work with is Monterey - please see #10676 (comment) A RealSense user did recently succeed in getting the camera working in Asahi Linux in a VM on an Apple Silicon Mac and shared an instruction guide. https://github.com/HasanTheSyrian/librealsense-hasan/blob/master/doc/installation_asahi.md |
|
So if i were to run it on ubuntu (which is comparatively easier) id have to downgrade my kernel? |
|
6.5 is currently the newest supported kernel version in SDK 2.55.1. However, if you were aiming to build SDK version 2.47 then the most recently supported kernel would likely be the older 5.4 and the newest supported Ubuntu version 20.04. If the SDK is built from source code with the -DFORCE_RSUSB_BACKEND=TRUE flag included in the CMake build instruction though then the Linux version or kernel version being should should not matter, as an RSUSB build of the SDK bypasses the kernel and is not dependent on a particular Linux version or kernel version. |
|
I think i will install SDK 2.54.2 like you mentioned earlier. I have an Ubuntu 22.04.4 booted on UTM. Can i follow the instructions on https://github.com/HasanTheSyrian/librealsense-hasan/blob/master/doc/installation_asahi.md ? If its something different please let me know and assistance would be helpful. |
|
SDK 2.54.2 is compatible with 22.04. If you encounter a problem when using the guide then I would recommend posting a comment to HasanTheSyrian at #12503 as they created the guide. |
|
I can also reach out to him through this thread right? |
|
If you put @ in front of HasanTheSyrian then you would tag him into this discussion, yes. |
|
after entering 'cmake ../ -DFORCE_RSUSB_BACKEND=true -DCMAKE_BUILD_TYPE=release -DBUILD_EXAMPLES=true -DBUILD_GRAPHICAL_EXAMPLES=true' I get the error message: -- The CXX compiler identification is unknown Tell CMake where to find the compiler by setting either the environment -- Detecting C compiler ABI info @MartyG-RealSense @HasanTheSyrian Please Help! |
|
@HasanTheSyrian I would clarify that @sai-srinivasan-v is attempting to use your Asahi Linux installation guide on their M2 Mac. |
|
NO @MartyG-RealSense I am using an ubuntu 22.04. I apologise for any confusion that i may have caused. |
|
I would also like to let you know that i have fixed the error it threw 2 responses earlier. |
|
Okay, no problem @sai-srinivasan-v - thanks very much for clarifying my clarification. :) |
|
This is what i see after 
|
|
The config.h error has been reported in the past with librealsense builds. A RealSense user at #6436 (comment) posts the solution that worked for them, which involves using the command |
Docs clearly advise not using VMs |
|
Hey @HasanTheSyrian , I'm sorry to keep bothering you i believe these are the libraries? |
|
make[2]: *** [examples/software-device/CMakeFiles/rs-software-device.dir/build.make:103: examples/software-device/rs-software-device] Error 1 should i be going into these directories? @HasanTheSyrian @MartyG-RealSense |
|
I don't know. I assume that the error is occurring because of the -DBUILD_EXAMPLES=true flag which tells CMake to build the RealSense example programs, including the rs-software-device example. |
Yes. Look inside |
|
this is the example.hpp file. what next? @HasanTheSyrian |
|
|
Okay i'll ignore it then. i also do not have the realsense viewer. |
|
Hi @MartyG-RealSense i somehow brought it to this. but when i try launching realsense-viewer it returns 'command not found' |
|
Hi @MartyG-RealSense i got into realsense-viewer but i still cannot connect my camera |
|
hi @MartyG-RealSense and @HasanTheSyrian i got the camera to work. Thank you guys so much. |
|
Feel free to close this thread |
|
That's excellent news, @sai-srinivasan-v - thanks very much for the update! @HasanTheSyrian - thanks so much again for your time and generosity in giving advice to @sai-srinivasan-v :) |
|
Hey @MartyG-RealSense I had some of my friends try to install the Realsense Viewer and even i couldnt help them out. I would like to request you to make an updated step by step tutorial for anyone thats facing this difficulty. Please do the needful. |
|
One of my Intel RealSense colleagues is looking at the problems of installation on Apple Silicon 'M' models of Mac to see whether an instruction guide is possible. There is not news to report about this effort at the time of writing this though. |
|
Hey Marty! I hope you're doing good. I got the camera to work except now when i try to open the realsense viewer it threw a segmentation error. And also i have a python script that uses pyrealsense 2 though i can read the camera through the |
|
This segmentation error with realsense-viewer on MacOS is something that other RealSense users with Apple Silicon Macs have experienced. There is not currently a known solution for this. At #9916 (comment) a user said "I can run the realsense-viewer from the terminal with sudo, once I add the app manually to the accessibility tab in system preferences/security". A RealSense user created a pre-built version of the pyrealsense2 wrapper for Mac at #9687 though it has been reported to have problems with recent MacOS versions such as Ventura and Sonoma. |
|
These are all issues that are from an Ubuntu Machine. |
|
You have an M2 Mac but were attempting to use Ubuntu or Asahi Linux earlier in this discussion. Was it MacOS that you are having the realsense-viewer segmentation error and Python non-detection of the camera on, please? |
|
True. But I got it to work on Ubuntu(UTM) and things were fine. And then Realsense threw a segmentation error. Everything i discussed here happened on an Ubuntu Machine running on UTM. I quit trying to install real sense on my Mac. |
|
I researched the history of segmentation errors in realsense-viewer on Ubuntu. In almost all cases there was no solution, unfortunately. The one user who claimed that they found a solution said that they closed down the Ubuntu terminal (which can be done by selecting Exit) and then restarted the terminal (you can open a terminal with the Ctrl+Alt+T keyboard shortcut). Then they input the realsense-viewer command to launch it. |
|
Yeah that simply launches realsense and it does not detect the camera. Also i tried running the python script as a root user and received pipeline = rs.pipeline() |
|
I moved it into the python directory inside wrappers and it works fine. Are there programs that are written by other users that i can use though? @MartyG-RealSense |
|
I'm pleased to hear that you achieved a solution! The Python wrapper has a range of example programs at the link below. https://github.com/IntelRealSense/librealsense/tree/master/wrappers/python/examples There are many Python scripts created by RealSense users. The easiest way to find them is to perform a web search that starts with the term librealsense python and add the name of the feature that you want a script for on the end of the search. You will get the most relevant results if you place the subject word in quotation marks. For example, librealsense python "laser power" |
Is there any relevant progress recently? I use a MacBook with m2, but the last problem remains:failed to set power state.Thanks a lot! |
|
Hi @OxO-7 My Intel RealSense developer colleague who has been looking at Mac support will update me once they find a solution for Apple Silicon support. There is not further news at present. I will ask them about it. |
|
Hi@MartyG-RealSense. Is Asahi the only way right now? I am confused. #12972 M processor and macos-14 are mentioned here, compilation issues are resolved but can't use realsense on macos-14? |
|
The 2.55.1 version of librealsense was released in April 2024, before the changes in #12972 were merged into the SDK on May 29 2024. The MacOS 14 changes are in the current latest 2.56.1 librealsense version, as confirmed in 2.56.1's release notes.
2.56.1 is currently an 'interim beta' release which can only be installed by source code compilation. It sounds as though this will not be a problem for you though as you have already performed a compilation. https://github.com/IntelRealSense/librealsense/releases/tag/v2.56.1 |
|
Thank you very much！ |
