v0.7.0

v0.7.0 (2021-12-31)

• Remove Genode bindings (#494, #506)
  The Genode bindings becomes incompatible with the upcoming LLVM/Clang based
  toolchain. It can be reinstated in the future if there is interest.

  GENODE_ABI_TARGET is not removed to disallow to re-use it for another
  purpose than the Genode binding.

• New packaging, toolchains, cross-compilation (#494, #506)

  • Make Solo5 installable system-wide and be able to packaging Solo5 for the
    BSDs and Linux distributions
  • Replace Solo5-internal use of pkg-config by generated toolchain wrappers
    installed as "PREFIX/bin/ARCH-solo5-none-static-{cc,ld,objcopy}"
  • Solo5 bindings (ABIs) are co-installable under the same PREFIX
  • OPAM packaging is simplified (only one package solo5 remains)
  • Experimental: support for the cross-compilation (specially aarch64)

• virtio: FreeBSD requires the grub-bhyve command (#506)

• virtio: FreeBSD: wait a bit for cat to create the nmdm device (#506)

• OpenBSD: all supported releases of OpenBSD use ld.ldd (#495, #506)

• Be able to release our cross toolchain via our opam-release.sh script (#504)

NOTE: pkg-config still is required by Solo5 to get flags from
libseccomp.
