# Safer build options
|
||
|
|
|
||
|
|
By default,
|
||
|
|
the Rust compiler includes your current path information
|
||
|
|
in the binaries that it generates.
|
||
|
|
This could be a problem if,
|
||
|
|
for example, you are building from a path like
|
||
|
|
`/home/FirstnameLastname/build/arti`
|
||
|
|
and releasing binaries (or uploading backtraces)
|
||
|
|
under a pseudonym
|
||
|
|
that you do not want linked to `FirstnameLastname`.
|
||
|
|
|
||
|
|
There is a good overview of the issues here at
|
||
|
|
https://github.com/betrusted-io/xous-core/issues/57 .
|
||
|
|
|
||
|
|
There are a couple of workarounds here.
|
||
|
|
|
||
|
|
# Workaround one: reproducible build
|
||
|
|
|
||
|
|
If you have Docker,
|
||
|
|
you can run a reproducible build of Arti,
|
||
|
|
so that the binary you make will be the same
|
||
|
|
as a binary generated by anybody else.
|
||
|
|
|
||
|
|
See the
|
||
|
|
[`docker_reproducible_build`](../maint/docker_reproducible_build)
|
||
|
|
script for more information.
|
||
|
|
|
||
|
|
# Workaround two: RUSTFLAGS
|
||
|
|
|
||
|
|
As a quick-and-dirty solution,
|
||
|
|
you can use the `--remap-path-prefix` option
|
||
|
|
to tell the Rust compiler
|
||
|
|
to re-map your paths into anonymized ones.
|
||
|
|
|
||
|
|
This is not a perfect solution;
|
||
|
|
there are known issues under some configurations,
|
||
|
|
particularly if you are linking to a static OpenSSL.
|
||
|
|
|
||
|
|
Personally, I get good results from running:
|
||
|
|
|
||
|
|
```
|
||
|
|
RUSTFLAGS="--remap-path-prefix $HOME/.cargo=.cargo --remap-path-prefix $(pwd)=." \
|
||
|
|
cargo build --release -p arti
|
||
|
|
```
|
||
|
|
|
||
|
|
After you do this, you can use
|
||
|
|
`strings target/release/arti | grep "$HOME"`
|
||
|
|
to see if your home directory appears in the result.
