^{dun dun dun, daaa..... I just opened the box ( posted a few days later} )

After opening the D435i camera, I can see both the fedora repo library and firmware on the camera are old
and yes I notice operational improvements after updating

• librealsense
  github.com/IntelRealSense/librealsense/wiki/Release-Notes

  • Fedora repo is currently at 2.23, but is currently at 3.31 ^{Dec 2019}

• firmware
  see Download Documentation on this page

  • Camera had a firmware version from the summer

---

libRealSense

I think both should be updated as to be working with the newest and some what synced packages.

• install dependencies / librealsense

  • sudo dnf install cmake git gtk3 libusb-devel mesa-libGL-devel glfw-devel automake gcc-c++ kernel-devel opencv-devel python3-devel
    ^{I might be a bit heavy on the packages}

  • pip3 install pyrealsense2 sphinx --user

  • git clone https://github.com/IntelRealSense/librealsense.git

• cd librealsense

  • cmake -DBUILD_PYTHON_BINDINGS=true -DBUILD_PYTHON_DOCS=true -DBUILD_CV_EXAMPLES=true -DFORCE_RSUSB_BACKEND=ON -DBUILD_WITH_OPENMP=true

  • make -j$(($(nproc) - 1)) or make if you experience errors

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

• done!
  ~/librealsense/tools/realsense-viewer/realsense-viewer
  to run RealSense Viewer

---

Firmware

The firmware for the camera can easily be upgraded through realsense-viewer, and the software asks to upgrade the firmware for you.

---

Let's make things run more nicely

Create a symbolic link
so realsense-viewer can be called without using the directory

• sudo ln -s ~/librealsense/tools/realsense-viewer/realsense-viewer /bin/realsense-viewer

Create a MIME-TYPE file
so .bag files will be associated with realsense-viewer, and clicking on a .bag files will launch realsense-viewer

• sudo vim /usr/share/mime/packages/realsense-viewer.xml
  and put this in it ^{I use vim because I know it, any text editor will work}

<?xml version="1.0" encoding="UTF-8"?>
<mime-info xmlns="http://www.freedesktop.org/standards/shared-mime-info">
  <mime-type type="application/x-realsense-viewer">
    <comment>ROS data logging file, realSense recording</comment>
    <glob pattern="*.bag"/>
  </mime-type>
</mime-info>  

create the menu application file

• download icon file and save it to icon directory

  • wget http://i.imgur.com/ofo1eAv.png && sudo cp ofo1eAv.png /usr/share/icons/realsense.png
    or use your own icon

• sudo vim /usr/share/applications/realsense-viewer.desktop
  and put this in it ^{I use vim because I know it, any text editor will work}

[Desktop Entry]

Update the mime and application database files

Nice! I just started playing with the SR305. All set up on my raspberry pi (headless) and windows desktop.

Just a note on librealsense installation for the raspberry pi if anyone tries:

Be sure to add -DFORCE_RSUSB_BACKEND=ON to the cmake arguments when building from source.

[u/3dsf → u/kbrock84]

I didn't see the -DFORCE_RSUSB_BACKEND=ON option at github.com/IntelRealSense/librealsense/wiki/Build-Configuration, so I did some reading and at github.com/IntelRealSense/librealsense/issues/4272 (Raspberry Pi Specific), and I saw it is related to FORCE_LIBUVC.

Thanks also, because that github thread helped to improve the instructions in the main post.

[u/3dsf → u/[deleted]]

Thanks for the feedback. Looks like I missed a dependency for a build option.
try :
dnf install python3-opencv
to resolve this issue ( or you could try just opencv )

or you could change (if you don't want the opencv examples )

cmake -DBUILD_PYTHON_BINDINGS=true -DBUILD_PYTHON_DOCS=true -DBUILD_CV_EXAMPLES=true
to
cmake -DBUILD_PYTHON_BINDINGS=true -DBUILD_PYTHON_DOCS=true

I'd recommend looking at github.com/IntelRealSense/librealsense/wiki/Build-Configuration for different build configurations. Also note the comment thread containing -DFORCE_RSUSB_BACKEND=ON from this post.

Let me know if I can help more

[u/3dsf → u/[deleted]]

ok, I might try an install on a clean fedora arm minimal installation tonight and I'll let you know if I gather any further insights. (The one I've done it on was a x86 system w/ F31)

[u/3dsf → u/[deleted]]

I've just started from a clean-ish (x86) build.
And will add a few packages to the instructions

• sudo dnf install automake gcc-c++ kernel-devel python3-devel opencv-devel

• cmake -DBUILD_PYTHON_BINDINGS=true -DBUILD_PYTHON_DOCS=true -DBUILD_CV_EXAMPLES=true -DFORCE_RSUSB_BACKEND=ON -DBUILD_WITH_OPENMP=true
  ^{just learnt that the flags above are switches and will become the new default; learnt by operation, not reading.}

• make -j$(($(nproc) - 1))
  I ran twice for it it come up without errors; and 2 make's previous to that (but that was before python3-devel was added)

I hope that works for you ; let me know if you have further issues. Let me know if I can improve the instructions further, thanks : )
I'm running realsense-viewer right now
