# Building Lemmy Images
|
||||
|
||||
Lemmy's images are meant to be **built** on `linux/amd64`,
|
||||
but they can be **executed** on both `linux/amd64` and `linux/arm64`.
|
||||
|
||||
To do so we need to use a _cross toolchain_ whose goal is to build
|
||||
**from** amd64 **to** arm64.
|
||||
|
||||
Namely, we need to link the _lemmy_server_ with `pq` and `openssl`
|
||||
shared libraries and a few others, and they need to be in `arm64`,
|
||||
indeed.
|
||||
|
||||
The toolchain we use to cross-compile is specifically tailored for
|
||||
Lemmy's needs, see [the image repository][image-repo].
