Building a Statically Linked Routinator
While Rust binaries are mostly statically linked, they depend on libc which, as least as glibc that is standard on Linux systems, is somewhat difficult to link statically. This is why Routinator binaries are actually dynamically linked on glibc systems and can only be transferred between systems with the same glibc versions.
However, Rust can build binaries based on the alternative implementation
named musl that can easily be statically linked. Building such binaries is
easy with rustup. You need to install musl and the correct musl target
such as x86_64-unknown-linux-musl for x86_64 Linux systems. Then you
can just build Routinator for that target.
On a Debian (and presumably Ubuntu) system, it goes somewhat like this:
sudo apt-get install musl-tools
rustup target add x86_64-unknown-linux-musl
cargo build --target=x86_64-unknown-linux-musl --release
Building on CentOS 6
If you are trying to build Routinator on CentOS 6, you will end up with a long list of error messages about missing assembler instructions. This is because the assembler shipped with CentOS 6 is too old.
You can get the necessary version by installing the Developer Toolset 6 from the Software Collections repository. On a virgin system, you can get Routinator in these six steps:
sudo yum install centos-release-scl
sudo yum install devtoolset-6
scl enable devtoolset-6 bash
curl https://sh.rustup.rs -sSf | sh
source $HOME/.cargo/env
cargo install routinator
