alt UNIX support

[mcandre]

Awesome that ops supports Linux and macOS! Could we get some ports going for ops to FreeBSD, NetBSD, OpenBSD, HardenedBSD, DragonflyBSD, Illumos, MINIX, and hopefully Haiku as well?

Note that a similar competing product, CloudABI, supports many of these BSD environments.

the bsd's should be relatively straight-forward to do yes, would just need to keep in mind the binary format - ops inherently uses elf's (for instance there is no support for mach-o on osx nor is there any planned) - however that's not as limiting as you might think since the vast majority of people will being using interpreters, vm runtimes or otherwise already-packaged software in the form of packages

I think a step-forward in this direction would be to simply compile it, see where it breaks and once you get a hello world working we can add/edit the release script for it - I'd also be in favor of adding pre-built packages for various os's

Hello, i try to build ops on FreeBSD 13.0 64 Bit, but don`t know how to fix this.

root@freebsd:~/go/src/ops # make build
go build -o ops -v

How can I help with add support of FreeBSD OS to this project? In the future I like to have ability run nanos unikernel in bhyve hypervisor on FreeBSD with running linux ELFs binaries inside, of course.

[eyberg]

two things:

1. we only run ELFs and don't have plans for other file formats

2. we currently don't have bhyve support but could look at adding that

I don't know offhand if qemu would work on fbsd right now or not, you could build a unikernel on a diff machine and test manually - if that works we could roll in some qemu support for at least running but bhyve is prob what should be used there instead

[asyslinux]

Yes, I understand about ELF format. In freebsd good hypervisor is bhyve, there is no point in running unikernel in qemu on freebsd. I will be grateful if You will add bhyve support. Thanks.

With qemu, simple unikernel "hello world" app on freebsd:

[root@freebsd ~]# qemu-system-x86_64 -drive format=raw,file=hello.img -nographic

SeaBIOS (version rel-1.13.0-0-gf21b5a4aeb02-prebuilt.qemu.org)
