Building the Debian package with pre-compiled binaries

Pre-compiled Rust binaries can be downloaded from: https://static.rust-lang.org/dist/index.html

Download pre-compiled rust and cargo binaries

$ wget https://static.rust-lang.org/dist/rust-1.20.0-powerpc64-unknown-linux-gnu.tar.gz

In case the download fails because of missing certificates, install the CA certificates and retry:

# apt install ca-certificates

Building rustc and cargo without pre-compiled binaries

Cross-compiling cargo

  • Define the linker name for the target architecture in your cargo config:

glaubitz@z6:~> cat .cargo/config 
[target.powerpc-unknown-linux-gnu]
linker = "powerpc-linux-gnu-gcc"
glaubitz@z6:~>
  • Install the build dependencies for the cross-compilation

# apt build-dep cargo
# apt install gcc-powerpc-linux-gnu g++-powerpc-linux-gnu
# dpkg --add-architecture powerpc # Note: For ports architectures, you need to add ftp.ports.debian.org/debian-ports to your sources.list
# apt update
# apt install libcurl4-gnutls-dev:powerpc libssh2-1-dev:powerpc libgit2-dev:powerpc libhttp-parser-dev:powerpc libssl-dev:powerpc zlib1g-dev:powerpc
  • Download the source for the current cargo package:

$ apt-get source cargo
$ cd cargo-0.25.0
  • Cross-compile the Debian package

$ DEB_BUILD_PROFILES="nocheck" DEB_BUILD_OPTIONS="nocheck" dpkg-buildpackage -B -d --host-arch=powerpc
