failed build on arch linux

[blind-confused]

for some reason, it didn't work... I ran the following commands:

sudo pacman -S lm-sensors
sudo sensors-detect

and saved the output, then installed rust using the official website instructions (which means using the following command): curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh then I ran:

cargo install just
sudo pacman -S make bison flex clang --confirm

but when I ran just libsensors, it just said error: No justfile found same thing happened after I tried uninstalling just and rust, and then reinstalling them, but from arch repositories. Honestly not sure what's wrong...

Maybe a dumb question, but did you clone the repo and cd in fan-control?

well... no, I guess I didn't. I listed all the steps that I took here (at least the ones I could recall) tbh I'm still new to linux in general, and I don't really have experience of installing non-repo apps, so... I make very silly mistakes like this speaking of... would it be okay to ask you to write down the exact commands I need? :,) (I'm sorry)

[wiiznokes]

No worries, we all been there. I updated the doc to make it even clear for beginners: https://github.com/wiiznokes/fan-control/blob/main/BUILD.md

[wiiznokes]

Notice you will need to run in sudo to be able to modify the value of PWM sensor (fans). So sudo ./target/release/fan-control.

After building the app obviously (cargo run --release or cargo build --release)

[blind-confused]

thank you, I'll try it soon and probably close this issue meanwhile... do you have any advice in general, on how to be safe with controlling the fans? I use a laptop, and I was going to use this app primarily to either slow them down, put a limit to their speed, or silence them altogether, because sometimes I get tired of the fan sounds. but I also feel a bit concerned that I might lead my computer to overheating by doing this... the only thing I know is that anything above 70°C should be concerning. But I was wondering if there is any other advice I also wonder if there are separate temperatures for different sections of the laptop, or just one overall temperature that needs to be worried about

[wiiznokes]

Well, they can be one item per sensor, so you can create different behavior based on a specific sensor(CPU for example). If you don't want to go above 70°C, you could use the target behavior. Or the linear. Personnaly, I'm only using this app to game and put all my fan at full speed

[blind-confused]

hmm... it just finished building, auto-launched and...

... and after this, it keeps repeating [WARN ui] An update is already processing: skipping that one. a lot of times it also looks like this, for some reason.

[wiiznokes]

Hum, from what I see you have no pwm sensor detected. The only solution is to run sensor-detect and answer yes every time, but i think you already did that so probably you're fan can't be controlled (it's frequent on laptop).

For the icons being black, maybe it's a bug with vulkan, you could try to set ICED_BACKEND=tiny-skia before running.

As for the error message, this is weird, it should never happened on Linux. Maybe retry with sudo

I did it a few days ago, and have shut down my laptop a lot of times since then, as well as reinstalled rust, just, make, clang, flex, bison. Does it need to be done again?

probably you're fan can't be controlled (it's frequent on laptop).

got it, I guess I will cry :,,

Maybe retry with sudo

well... sudo: ./target/release/fan-control: command not found

[wiiznokes]

well... sudo: ./target/release/fan-control: command not found

You must be in the fan-control folder for this.

got it, I guess I will cry :,

Yeah this is sad, but maybe is could be improve, will see

[blind-confused]

You must be in the fan-control folder for this.

you mean cd fan-control? just tried that, it says error: XDG_RUNTIME_DIR is invalid or not set in the environment.. It does launch the app though, with the same black squares. But without endlessly repeating errors in the terminal

Yeah this is sad, but maybe is could be improve, will see

well, even if not, I still appreciate your help

[wiiznokes]

Closing because the icons now should work with flatpak
