Bend command not found

[milen-prg]

Describe the bug
I installed the Bend lang on WSL2 Windows 11 Pro 64 bit, Ubuntu 24:
BUT:

user@DESKTOP-UID:/mnt/c/Users/User/Downloads$ cargo +nightly install hvm
Updating crates.io index
Ignored package hvm v2.0.8 is already installed, use --force to override
user@DESKTOP-UID:/mnt/c/Users/User/Downloads$ cargo +nightly install bend-lang
Updating crates.io index
Ignored package bend-lang v0.2.7 is already installed, use --force to override
user@DESKTOP-UID:/mnt/c/Users/User/Downloads$ bend --help
Command 'bend' not found, did you mean:
command 'tend' from snap tend (0+git.1ad02aa)
command 'ben' from deb ben (0.10.3ubuntu2)
command 'blend' from deb mrtrix3 (3.0.4-1)
command 'send' from deb mailutils-mh (1:3.16-1build1)
command 'send' from deb mmh (0.4-6)
command 'send' from deb nmh (1.8-1)
command 'bnd' from deb bnd (5.0.1-4)
See 'snap info ' for additional versions.

I'm not sure if this will help, but here is the list of commands I ran that got Bend working on my Ubuntu system:

sudo apt -y update
sudo apt install -y build-essential
sudo apt install -y curl

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs/ | sh

# NOTE: iis use zsh for my shell, if you use bash source the ".bashrc" file
source ~/.zshrc

rustup default nightly

cargo +nightly install hvm
cargo +nightly install bend-lang

I think you might not have included the cargo bin directory in you PATH environment variable.
Can you echo $PATH?
It should include something about cargo, for me it has /home/nicolas/.cargo/bin/ (i'm on linux, might be a different location on wsl)

[milen-prg]

@developedby , I added export PATH=$PATH:~/.cargo/bin/ to my .bashrc, then made bend1.hvm file with:
def main():
return "Hello, world!"

and tried:
user@DESKTOP-UID:~/prb$ bend run-cu bend1.hvm
Errors:
Error reading result from hvm. Output :
CUDA not available!

(I tried run and run-c, they work: Result: "Hello, world!")

I tried to install also:
sudo apt install nvidia-cuda-toolkit

but this nothing changes.

On the Windows system I have NVIDIA GeForce RTX 3060 with Driver Version: 552.44 CUDA Version: 12.4.

I tried to install also:
sudo apt install nvidia-cuda-toolkit

I wonder which drivers you're using... Can you run

lshw -c video | grep "driver"

and see what it says? That will tell us more.

@developedby , I added export PATH=$PATH:~/.cargo/bin/ to my .bashrc, then made bend1.hvm file with: def main(): return "Hello, world!"

and tried: user@DESKTOP-UIDK5MM:~/prb$ bend run-cu bend1.hvm Errors: Error reading result from hvm. Output : CUDA not available!

If you didn't have CUDA installed when you compiled HVM then it won't have run-cu available.
If you installed CUDA after installing HVM, you need to reinstall it and it will add the CUDA part

@developedby , i tried to reinstall, but:

It's too complex for me, I apologize, but I'm not so curious (and experienced!) for now. I wish to this lang to develop forward and maybe when I can try natively on Windows, I will try again.
Thanks!
