You’ll likely need to create swap space in order to build but it should work

Anybody know what to do with this error I am getting when trying to compile the node?
pi@raspberrypi : /home $ sudo ~/.cargo/bin/cargo build --release
error: no override and no default toolchain set
rustup install stable
rustup default stable
Looks like it installed rust, but still no access.
pi@raspberrypi : /home $ rustup install stable

stable-armv7-unknown-linux-gnueabihf unchanged - rustc 1.48.0 (7eac88abb 2020-11-16)

We are not yet fully ready with our auto-deployment and help you with your installation problems. But you could start having a look at : https://github.com/MCM-Mike/Grin-Pi/blob/master/doc/puppet.md

Hey,
thanks for this, I tried the official instructions but I had compile errors in rust after I had installed rust from apt get. After I apt remove rust and installed from rustup.rs, it works!
I installed it on my raspberry pi 4/4Gb, with the chain data on a ssd. It works alongside a Bitcoin Core node and started syncing. The pi is still usable as a desktop, but I am thinking of getting a second pi

Hi. I’m new. Are these for sale? Or build your own? How much do they make?
Hi @Slydoggrx, these will probably go on sale at the end of this year. The design of the casing is however just open source, so you can also print it yourself, buy a raspberry Pi and install the software.
A node earns nothing. Grin does not use a secure or master node system (in which case you secure the network by staking), so a node is just there to strengthen and validate the network and for you to validate your transactions if you install it together with the grin-wallet (rust implementation), so you can have your wallet on the Raspberry Pi.
If you want to earn Grin, the best way is to mine yourself using a G1 Mini miner from Ipollo, they are sold via Nhash, see this link for more information:
Be ready so shelf out some money though, they are 900$ or so.
Running a node earn nothing, unlike mining. As a fan of any coins, we normally run one-two nodes to support that blockchain network.
Personally I run 4-5 Grin nodes just for fun.

Hello, I followed your tutorial to make a node on Raspberry 4
it seems that I have problems of RAM memory and can not pass the step 3/7 of synchronization
I have a Raspberry 4, 4go ram, does an 8go solve the problem ?
or a swap-file ? I don’t know why I can’t use it for the moment. (swap-file still free).
I get this error : TxHashSetErr: Cannot allocate memory.
Thx.
We are using the 8GB RAM RPI4 , this should solve your problem.
Swap file is not as important as the RAM, I would adjust the SWAP file once you have your system running.
