Closes#51339
This should address issues with too new libstdc++.so on older/more
conservative distros such as RHEL9.
Release Notes:
- Relaxed requirement for libstdc++.so available on Linux distros.
If I follow the steps outlined in https://zed.dev/docs/development/linux
then `cargo run` on my Fedora workstation fails because the install
script is missing `libva-devel` as a required dependency under `dnf` /
`yum` sections.

# Summary
Today, Zed uses Mold on Linux, but Wild can be significantly faster.
On my machine, Wild is 14% faster at a whole-tree clean build, 20%
faster on an incremental build with a minimal change, and makes no
measurable effect on runtime performance of tests.
However, Wild's page says it's not yet ready for production, so it seems
to early to switch for production and CI builds.
This PR keeps using Mold in CI and lets developers choose in their own
config what linker to use. (The downside of this is that after landing
this change, developers will have to do some local config or it will
fall back to the default linker which may be slower.)
[Wild 0.6 is out, and their announcement has some
benchmarks](https://davidlattimore.github.io/posts/2025/09/23/wild-update-0.6.0.html).

# Tasks
- [x] Measure Wild build, incremental build, and runtime performance in
different scenarios
- [x] Remove the Linux linker config from `.cargo/config.toml` in the
tree
- [x] Test rope benchmarks etc
- [x] Set the linker to Mold in CI
- [x] Add instructions to use Wild or Mold into `linux.md`
- [x] Add a script to download Wild
- [x] Measure binary size
- [x] Recommend Wild from `scripts/linux`
# Benchmarks
| | wild 0.6 (rust 1.89) | mold 2.37.1 (1.89) | lld (rust 1.90) | wild
advantage |
| -- | -- | -- | -- | -- |
| clean workspace build | 176s | 184s | 182s | 5% faster than mold |
| nextest run workspace after build | 137s | 142s | 137s | in the noise?
|
| incremental rebuild | 3.9s | 5.0s | 6.6s | 22% faster than mold |
I didn't observe any apparent significant change in runtime performance
or binary size, or in the in-tree microbenchmarks.

I ran `scripts/linux` on Debian Trixie 13. It suggested manually
installing Mold, but [mold](http://packages.debian.org/mold) is packaged
on Debian and so we could install it automatically.
The version packaged there seems to work well enough for `cargo t` to
pass, at least.
## Tested
```
; sudo apt remove mold libstdc++-14-dev
... uninstalls them
; ./script/linux
The following NEW packages will be installed:
build-essential clang clang-19 clang-tools-19 g++ g++-14 g++-14-x86-64-linux-gnu g++-x86-64-linux-gnu libstdc++-14-dev mold
; cargo t
(passes)
```

Release Notes:
- Removed the need to have openbsd `netcat` (`nc`) installed on your
system in order to enter passwords for `git` or `ssh` (remote
development). If you previously installed `netcat` specifically for Zed,
you may uninstall it.
Reapplies #27807 after [revert due to not building on

While `scap` does have support for Wayland and Windows, but haven't seen
screensharing work properly there yet. So for now just adding support
for X11 screensharing.
WIP branches for enabling wayland and windows support:
* https://github.com/zed-industries/zed/tree/wayland-screenshare
* https://github.com/zed-industries/zed/tree/windows-screenshare
Release Notes:
- Added support for screensharing on X11 (Linux)

In `script/linux` file, in order to install build dependencies we check
ID and VERSION_ID fields of `/etc/os-release` file for installing
os-specific packages. The regex patterns for those fields are wrong
because there's no `"` character after `ID=` or `VERSION_ID=`. This
causes `grep` to fail.
So I extended the pattern by adding `"?` after each `"` character to
bypass the cause of failure.

This addition comes after attempting building Zed from source.
As part of the process, one of the components (a crate I presume) called
`ring` failed to compile due to the following sequence of console
messages:
```log
warning: ring@0.17.8: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `musl-gcc` installed?
warning: ring@0.17.8: Compiler family detection failed due to error: ToolNotFound: Failed to find tool. Is `musl-gcc` installed?
error: failed to run custom build command for `ring v0.17.8`
```
Adding this library should help fix the issue on Fedora 41 at least, and
possibly will help fixing it for other RedHat based distributions as
well.
Closes #ISSUE
Release Notes:
- Add musl-gcc as dependency
Signed-off-by: Agustin Gomes <me@agustingomes.com>
- Add `script/build-docker`
- Add `script/install-cmake`
- Add `script/install-mold`
- Improve `script/linux`
- Add missing dependencies: `jq`, `git`, `tar`, `gzip` as required.
- Add check for mold
- Fix Redhat 8.x derivatives (RHEL, Centos, Almalinux, Rocky, Oracle, Amazon)
- Fix perl libs to be Fedora only
- Install the best `libstdc++` available on apt distros
- ArchLinux: run `pacman -Syu` to update repos before installing.
- Should work on Raspbian (untested)
This make it possible to test builds on other distros using docker:
```
./script/build-docker amazonlinux:2023
```

```
The script fails to install zed on Arch Linux due to a missing
dependency, `jq`.
## My machine info
OS: Arch Linux
Kernel: 6.6.34-1-lts
WM: dwm
Terminal: kitty
CPU: Ryzen 5 5500U with Radeon Graphics
GPU: AMD ATI 04:00.0 Lucienne
Memory: 16 GB
## Error Description
The error occurs when running the script in `script/install-linux`,
which is unable to find the `jq` package, which is not installed by
default on the machine.
## Solution
To resolve this issue, you can install `jq` independently by running
`sudo pacman -S jq`. Alternatively, I have updated script `script/linux`
to include `jq` as a dependency ([link to the
commit](2349ad111f)),
ensuring it is installed automatically when running the initial script
for system libraries.

Note that, contrary to the issue's text, we're still shipping a
statically bundled sqlite3 after this PR. We use enough new features of
sqlite, like `sqlite3_error_offset` and `STRICT`, that our minimum
version (v3.38.0) is higher than is presumably accessible on Ubuntu.

I found that builds failed on Arch and OpenSUSE so I added missing
dependencies. I also found that OpenSUSE Leap is currently not able to
install the required dependencies so I added a check to limit the
supported distros to Tumbleweed.

This PR removes the references to initializing Git submodules as part of
building Zed.
These are no longer needed, as our only submodule was removed in #11672.

To speed up Linux CI builds, use a set of self-hosted Linux machines and
use them to run all slow CI steps for Linux: "tests", bundling and
nightly builds.
Also adds a set of dev icons as Linux bundling script required them for
`run-bundling`-tagged builds from regular PRs.
Same icons as for Preview were used, but, ideally, something different
could be created.
