Welcome. This discussions forum is a place to ask questions about the fprime software class setup.

Using my JPL Windows laptop, I am unable to install the python3-venv and python3-pip packages. I get the following error messages indicating that those packages are unavailable.

Doing this first seemed to resolve it for me:
sudo apt-get update

LeStarch Oct 13, 2022

Good catch! Yes, sudo apt update will ensure package listings are up-to-date.

I have added that to the list of instructions

ksali2 Oct 13, 2022

Thanks! That got me past that part of the instructions.

"git submodule update --init" lacks " --recursive" in prerequisites Step 2, but has it in appendix-3. Which is correct?

djbyrne17 Oct 14, 2022

Thanks. Also, the prerequisites state clearly that "cross-compilers require a Linux computer" and "a Linux box is essential" yet also point Mac users to appendix 2 for docker setup. Is the intention that a Mac with docker enables cross-compilation, and is an alternative to a linux box?

djbyrne17 Oct 14, 2022

...in which case, prerequistes step 2.5 could be explicitly "start docker".

appendix-2.md, at the end, instead of the note "~/fprime-system-reference should be replaced with /project in commands run in the container." could simply have

ln -s /project ~/fprime-system-reference

Docker provides the Linux environment for macOS users like WSL does for Windows users. I will add fixes for the above suggestions.

LeStarch Oct 14, 2022

Looking into this deeper: Docker is only required for the cross-compile and testing on hardware section. (Day 3 of the class). All other days can be done on macOS directly. I believe day 3 mentions running docker, but I will state this verbally that day.

Ok I added a note about the symbolic link. For the next class we can add that into the container so that it "just works" but that change is a little too destructive now that students are running through the exercises.

Running on M1 Mac within the docker cross-compile container. The generate and build commands work fine but I get this error when launching fprime-gds

When I'd built all the code natively on Mac, then later entered docker, the make system did not see a need to re-compile inside docker and I got weird error msgs.

Try re-naming, or removing, /fprime-system-reference/SystemReference/build-fprime-automatic-native/
and repeating

fprime-util generate
fprime-util build
fprime-gds

Doing that, I get

However, I do not get the GDS GUI in a web browser. Perhaps Rancher docker needs some port-forwarding to let 127.0.0.1:50000 get out of docker and into my may firefox. But we can get by without that, since we can code and debug in Mac (and write solid Unit Tests, of course!), and only use docker to cross-compile for the HW target on the last day of class. I think.

My Mac is Intel, not M1 like yours.

This is correct. We typically run only the cross-compile build in the container. We build and develop for the local development and tests natively on macOS. Thanks @djbyrne17.

If you want to really want to run inside docker you can repeat the following steps (inside the docker container) to generate a native linux build as the container runs docker.

fprime-util purge 
fprime-util generate
fprime-util build
fprime-gds

To see the GDS you'll need to open a browser and manually go to http://localhost:5000 directly. The ports are forwarded but the command to "launch a browser" cannot escape the container.

nihaldhamani Oct 14, 2022

Ah I see, thanks! @djbyrne17 @LeStarch

In the F' GDS window, I am not seeing the upper right corner change to a green circle. I tried sending a command, but there still remained only a red X.

Is this WSL, macOS, or Linux? On a local machine (e.g. laptop)? What errors/logs do you see (CLI output, "Logs" tab of the GDS)?

We can try to debug here. There will also be some time Monday to help with issues that came up while people installed.

nadyabalabanska Oct 14, 2022

I am using WSL on my JPL Windows laptop. When I run fprime-gds a Chrome window opens connected to 127.0.0.1:5000 which looks like this

I am not seeing the green circle in the upper right hand corner, just the red X.

No error output in the terminal:

We may need to look at this tomorrow. It seems to be running, but the connections aren't working. Are you running any VPN fixes or anything like that for WSL?

It looks like fprime-fpp is missing an ARM64 release for those on Mac M1's (see below). I happen to also have an x86 laptop that I've been able to set up F' on, but I know a few coworkers were also having the same issue running Ubuntu 20.04 via Parallels on Mac M1. Is there any suggested workaround?

Yes, we do not currently have support for any of the arm variants. This is why the mac OS instructions recommend docker as opposed to parallels or other virtualization technology and running on ubuntu arm64.

Following along with appendix 2 on an M1 mac, when I run the container I get the following warning: WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm64/v8) and no specific platform was requested.

I don't think this is actually a problem, and it is running the container, but I just wanted to document it.

Thanks for posting. I don't think this is an issue either. This will help others who come to post on that issue.
