# SH3009: The built program holds a path of the build machine

Source: https://zafnok.github.io/shuyi-engine/learn/errors/sh3009/

Class: operation, exit code 1.

A `--release` build (`export --release`, or `web --release`) remaps the
paths it was built from to short fixed names: the workspace to the
game's package name, each crate read by a path outside it to the
crate's name, Cargo's home to `/cargo`, rustup's to `/rustup`,
and the target folder to `/target`. Then it searches the built program,
or the `.wasm`, for the home folder, Cargo's home and the game's
folders, with either slash. One was still there, so the package would
carry the builder's user name and folders: it was refused. The message
names the file and the path found.

**How to fix it.** The remapping renames the paths of the source files
the compiler reads, not a path the code writes into the program as a
value: `env!("CARGO_MANIFEST_DIR")`, a build script's `OUT_DIR`, a path
`include_str!` shows in a message. Find the crate whose code does that
(search its sources for the path's start) and keep the path out of what
ships: a path from the game's own folder, or a name. Keep Cargo's home
and the target folder where Cargo puts them, or set `CARGO_HOME` and
`CARGO_TARGET_DIR` for the export too. Then export again.

For example:

```text
export: error[SH3009]: the build holds a path of the build machine: dist/export/linux/game-0.1.0-linux/game holds /home/me; the package is refused
```
