I'm trying to compile proxmox.git but I'm having problems with it

Here's how I did it


Bash: 
echo 'deb http://download.proxmox.com/debian/devel/ bookworm main' | tee /etc/apt/sources.list.d/proxmox-devel.list

wget https://enterprise.proxmox.com/debian/proxmox-release-bookworm.gpg -O /etc/apt/trusted.gpg.d/proxmox-release-bookworm.gpg

apt update

apt install -y devscripts debcargo clang

Installing the rust toolchain
Bash: 
apt install -y cargo rustc

curl https://sh.rustup.rs -sSf | sh

rustup toolchain install nightly

cp -a ~/.rustup/toolchains/nightly-x86_64-unknown-linux-gnu/ ~/.rustup/toolchains/system

rustup default system


Get the source code and compile it
Bash: 
git clone git://git.proxmox.com/git/proxmox.git

cd proxmox

make deb


Then I get this error

It says. error: Toolchain system in /root/proxmox/build/rust-toolchain is custom and not installed

But I think it's already installed.

Bash: 
root@pve:~/proxmox# rustup show
Default host: x86_64-unknown-linux-gnu
rustup home:  /root/.rustup

----------------

system (default)
rustc 1.86.0-nightly (a730edcd6 2025-01-30)

The reason I want to compile the project is that I added the PVE mirror source, but WebUI still says: No Proxmox VE repository is enabled, you do not get any updates!
I want to fix it!

Then I investigated and found out that it's the one that determines if a PVE source has been added or not, and I'd like to modify it

What is this libpve_rs.so though, in the course of my investigation I found that it also contains links to the PVE sources
Bash: 
root@pve:~/# grep -r "http://download.proxmox.com/debian" /usr/lib/x86_64-linux-gnu/perl5/
grep: /usr/lib/x86_64-linux-gnu/perl5/5.36/auto/libpve_rs.so: binary file matches

grep: /usr/lib/x86_64-linux-gnu/perl5/5.36/auto/libpve_rs.so: binary file matches

The source code for libpve_rs.so is in this project https://git.proxmox.com/?p=proxmox-perl-rs.git;a=summary

git clone git://git.proxmox.com/git/proxmox-perl-rs.git

Hi!

Sorry for the delay. I hope you have found the solution to the problem already. Either way, I wanted to add some context here.

Proxmox projects are based on Debian and since there Rust crates are packaged, we do so too.

Therefore, we do use rustup to install the rust toolchain, but rustc, cargo, etc. packages, so that the toolchain versions are upgraded over the same package manager as all other packages. The same applies for crates and their features, which are also packaged as individual packages, e.g. librust-serde-1+default-dev and librust-proxmox-sys-0.6+default-dev.

This is correct!

The libpve_rs.so file is a shared object file, which is used so that the Perl code of Proxmox VE is able to run code written in Rust as we favor to write new functionality in Rust. This shared object is built by perlmod, which creates the shared object and the bindings for Perl.
