Please Help with compile?? RPI 5 raspberry os

[striork]

OK im probably missing something obvious, hopefully someone can help!! running the raspberry pi os i needed the source (doesnt execute .AppImage)
sudo ~/home/pi/Qt/6.7.0/gcc_arm64/bin/qmake

Well, one big problem you're going to have is that SavvyCAN was written for QT5.14 while you have QT 6.7 installed. Unfortunately QT6 just won't quite result in a working copy of SavvyCAN right now. But, there has been a lot of work to get it moving in that direction. So, it may compile but after that, you will probably run into issues.

What you are experiencing is that QT doesn't bundle all the add-ons with the base install. You need to install the serialbus and serialport packages as well. I don't know what they're called on Raspbian but you should be able to find them in the list of QT6 packages available.

Thanks for the reply. It appears my issue is the arm architecture! I can't find qt download for arm64 pre 6.0! I went from nothing to cansniffing in no time flat on my x86 lol. I tried building qt from source but have run into problems there as well. Apparently there were a handful of bugs, now patched obviously, but I've checked 2 dozen patches.. none of which did me any good! I am back to square 1... deflated... and tired! We'll see what tomorrow brings. Thanks again for your help JR

I just pushed a new version to the QT6WIP branch. This version is now at feature parity with the master branch. So, you can use the QT6WIP branch and compile with Qt6.7 on your RPI. This should yield a properly working copy of the program. I should really look into what it'd take to get a CI/CD build of SavvyCAN for ARM on the Raspberry PI.

[lucyyyyyyy]

+1 for a CI/CD build for ARM on the Raspberry Pi. I've been struggling all day trying to get Qt >5.15 but not Qt6 on the RPi to build, seems like I will have to try to build the QT6WIP branch.

[lucyyyyyyy]

@striork if you're still having issues compiling/running it, there is a nix package that has a build for aarch64, I got it working fine on a RPi 4 with 64-bit Raspberry Pi OS

[striork]

@lucyyyyyyy could you link it for me? no rush, I'm PI down ATM

[lucyyyyyyy]

@striork the package is here, https://search.nixos.org/packages?channel=23.11&from=0&size=50&sort=relevance&type=packages&query=savvycan / https://github.com/NixOS/nixpkgs/blob/nixos-23.11/pkgs/applications/networking/sniffers/savvycan/default.nix

If you have nix installed already you can just runnix run nixpkgs#savvycan or nix profile install nixpkgs#savvycan to install it.

If you don't have a nix package manager, I'd recommend lix, which you can find here https://lix.systems/install/, just make sure you're using 64-bit Raspberry Pi OS, it won't run on the 32-bit variant

[trebies]

Should this run on a Pi3 with a 64bit install?

[lucyyyyyyy]

I would think so, I don't have a Pi3 on hand, only a Pi4 - but it works fine on Pi4 64bit, so I can't see why it wouldn't work on a Pi3

[trebies]

Tested, the answer is yes, SavvyCan opens, haven't connected to a CAN source yet though!

[collin80]

I should mention that I've moved the QT6 support into the master branch so it should be possible to compile on QT6 (I think you might need QT6.5 or higher as they didn't add in SerialBus support in the early releases). So, it ought to compile as-is with the QT6 packages and the master branch. But, I haven't gotten around to trying it.

[striork]

@lucyyyyyyy @collin80 you are awesome! The PI5 is up and running It runs Raspbian, Ubuntu, and AOSP 14 pretry smoothly. With the dual MCP2515 I cant wait to get SavvyCAN on it this weekend! I'll post a status report ASAP.

[bfpa40]

I seen this and you might indeed have insight that I am looking for. I have a RaspberryPi 5 with Ubuntu 24.04 installed Im using a Waveshare 485/CAN hat and i have it all working but fighting to get a Pi5 compatible version of SavvyCAN running. I would GREATLY appreciate it if you could assist.. -Brian-

[striork]

Finally back at the Pi! I'm attempting to cross compile QT5 (6.4.0) on my PC in order to compile savvyCAN directly on the raspi. I ran into this

 Xkb2Qt<XKB_KEY_dead_lowline,            Qt::Key_Dead_Lowline
Xkb2Qt<XKB_KEY_dead_aboveverticalline,  Qt::Key_Dead_Aboveverticalline
Xkb2Qt<XKB_KEY_dead_belowverticalline,  Qt::Key_Dead_Belowverticalline
 Xkb2Qt<XKB_KEY_dead_longsolidusoverlay, Qt::Key_Dead_Longsolidusoverlay

Apparantly a while back there were these errors in the source. They patched them up right away, Bob's your uncle and everone's cute for qt!
From what I'm gatherimg it had to do with qxkbcommon scripting for virtual keyboards.
I found out the hard way that they only fixed certain branches... Lol. No sooner I get that straightened out, get the repo initialized again, its build time again! UGH! NO!

CMake Error at qtbase/cmake/QtTargetHelpers.cmake:171 (target_link_libraries):
  Target "XcbQpaPrivate" links to:

  but the target was not found.  Possible reasons include:

    * There is a typo in the target name.
    * A find_package call is missing for an IMPORTED target.
    * An ALIAS target is missing.

I started looking into this one and i noticed a few people also trying to cross compile coming up with the same errors. If any of you out there with a little more experience could point me in the right direction, I'd be super appreciative .
I'm just trying to talk to some cars...
Oh shit! as I'm about to copy and paste THIS:
(on this very page)

qxkbcommon<

and
THIS

XCB::CURSOR<
to point out the reference I notice the TYPO!! XCB != ckb but alas...no! Let me be perfectly clear when I tell you that I have NEVER had this much trouble with a wrench in my hand!
Please Help!
S'il vous plaît, aidez-moi !
Bitte helfen Sie!
Snälla hjälp!

[collin80]

This much I can say: I've not heard of anyone successfully cross compiling it. I've heard of people who did it directly on a Raspberry Pi but I have not tried it myself. It has just always seemed like more complication than it's worth to me. I have a laptop and I drag it around to cars and only every couple of years drop a laptop or accelerate hard in a car snapping the screen off or drop a 12V lead onto the top of a can capture card while it's plugged into the laptop and fry the motherboard (yes, I've done all three of those things). So, I just use the PC version and carry a laptop. Sorry I can't be of more help. All I know is that it is possible and some people have done it.

[collin80]

Actually... while looking for a different board I happened across an Rpi4B with a CAN hat on it and so I might as well give it a try. I'll install the latest RaspberryOS and see where this adventure takes me. It may be possible to publish compiled binaries. I think Rpi4 and Rpi5 are binary compatible so I'm pretty sure the same executable will work for either

[bfpa40]

That would be AMAZING!

[collin80]

I loaded the newest RaspberryOS onto an sdcard, updated all existing packages, then installed the following packages (sudo apt install):
qt6-base-dev
qt6-base-dev-tools
qt6-pdf-dev
qt6-serialbus-dev
qt6-serialport-dev
qt6-tools-dev
qt6-wayland
qt6-wayland-dev
qt6-wayland-dev-tools
qt6-webview-dev

From there I used git clone to download the SavvyCAN source. Then in the resulting folder:
git checkout QT6WIP
qmake6
make -j 6

This results in a full compile that takes a LONG time on an RPi4. I can compile all of SavvyCAN in about 16 seconds on my normal dev machine but it takes several minutes on the RPi. And... it works! I tested at least to be able to load the program and then load up a capture file and scroll around. I haven't tested much else and probably can't today. But, the above steps do yield a theoretically working build. All it takes is about 10 minutes of waiting when you start compiling. On an RPi5 you likely will not have to wait nearly as long.

[bfpa40]

AWESOME... I have a Pi 5 that I will try this on hopefully Friday evening after work! I currently have Ubuntu 24.04 running on it I might just try to do this on that build first and see what happens!

[striork]

Thank You!, Sir! I can't believe it was that easy. It took all of 5 minutes. Not having to compile QT was the game changer!

[artcore-c]

I have been trying to add SavvyCAN to my Raspberry Pi Compute Module CM-4 running Bookworm using the method you describe, however unsuccessful because I can only apt install qt6.4 (qt6.5 and above must be compiled for pi), and error I get is QT6WIP requires qt6.5 or above. Please help!!!

[artcore-c]

Fixed! had to remove clang-14 and llvm-14, then reinstall clang-dev and llvm-dev and qt6.7.2 now compiling!
hopefully QT6WIP will work for me now, I kinda think it will now as corrected the error, we'll see after qt finishes and it's installed.

My thought though is to change make -j 6 to make -j 4 when compiling since the Rpi CM-4 Compute Module only has 4 cores...
