• This release includes a number of changes to support building on many more platforms.
  • The full list of architectures that binaries are released for is:
    • FreeBSD x86-64 new
    • Linux x86-64
    • Linux aarch64 (aka arm64)
    • Linux arm (32-bit)
    • Linux i586 (x86 32-bit) new
    • Linux mips (32-bit) new
    • Linux mipsel (32-bit little-endian) new
    • Linux mips64 new
    • Linux mips64el (little-endian) new
    • Linux PowerPC (32-bit) new
    • Linux PowerPC64 new
    • Linux PowerPC64le (little-endian) new
    • Linux riscv64 new
    • Linux s390x new
    • NetBSD x86-64 new
    • Windows x86-64
    • Windows i686 (32-bit) new
    • Windows aarch64 (aka arm64) new
    • macOS x86-64
    • macOS aarch64 (aka arm64)
  • The code supports some other OS and CPU architectures internally, but I do not have any way to build these:
    • Fuchsia x86-64 and aarch64 - not supported by cross.
    • Illumos x86-64 - OpenSSL build fails with odd error about granlib executable.
    • Linux Sparc64 - not supported by OpenSSL.
    • Solaris x86-64 - supported by cross but building the mio crate fails.
    • Solaris Sparc - not supported by OpenSSL.
  • In order to do this, ubi now uses the openssl crate under the hood instead of rustls. That's because rustls depends on ring, which does not support nearly as many CPU architectures as OpenSSL. The vendored feature for the openssl crate is enabled, which causes it to compile and statically link a copy of OpenSSL into the resulting binary. This makes the resulting binary more portable at the cost of not using the system OpenSSL.
