Building rustc on Solaris

[eeyun]

@gurry

I think it depends on what version of rust you need. I haven’t attempted on Solaris 11 specifically but you could try using pkgsrc packages to install rust 1.14. The only challenge there being that it doesn’t give you cargo. https://pkgsrc.joyent.com/ . I started trying to build a bootstrap package for cargo to use for compiling a more recent rust on illumos but haven’t completed it yet.

Rust should now build natively on Solaris. A couple of us Oracle folks have pushed a number of fixes, so it should just work now, at least on nightly (well, beta now, I guess). I haven’t yet tried an unpatched 1.16, so I’m not sure about that. And there’s a fix to the fs2 crate that I still need to figure out the best solution, but if you get stuck on flock(), let me know and I’ll send you a patch.

Note that I haven’t yet tried Solaris 11, only S12, so there may be more fixes required, but I can’t think of any reason why it shouldn’t just work.

[eeyun]

@dhduvall thats awesome. I haven’t had much luck getting it to compile on illumos yet but perhaps I ought to try solaris 11.

[eeyun]

Definitely no luck on getting it to compile without an existing bootstrap image. Rust 0.16.X beta requires a cargo binary, and compiling cargo also requires the cargo binary. Unless I’m missing something solaris/illumos users will still have to get a stage-0 bootstrap image from somewhere?

[vojtechkral]

Well we have rustc and cargo on Solaris 12 (thanks to @dhduvall as well as others), I guess we should find a way to share that with S11 users. However, there’s still some bits and pieces not working 100% right, for example mio doesn’t compile on S12. I’ve been meaning to have a look at it but haven’t found the time yet.

Thanks guys and awesome news @dhduvall More power to you guys.Thanks for the hard work.

So here’s a dumb question . I’m still not quite sure how I can get rustc and stdlib to run on Solaris. Will I have to build it using the instructions on Rust Github repo? If yes, will following those instructions build stdlib as well along side rustc?

[eeyun]

If someone that’s gotten patched rust compiled on solaris 12 has the bootstrap image they used for both cargo and rust and can share them for local compile that would be suuuuuuper dope.

[dhduvall]

I’m going to have to check with our legal department first, so this may still take some time, but I’ll see what I can make available.

[gurry]

Thanks @eeyun. I completely missed seeing your post. Sorry about that. I’ll try the pkgsrc method as well

[gurry]

I tried to compile using instructions on the rust github repo and it failed with a 404. Same as the OP. Now I finally understand all this talk about bootstrap/stage0 binaries (sorry, I’m a bit new to this stuff). So, looks like no bootstrap binaries are available for Solaris11 . Let’s wait for @dhduvall and see if can help us there.

@eeyun Based on the above, looks like the pkgsrc method won’t work either. Isn’t that so?

[eeyun]

@gurry sorry for the slow response. The pkgsrc method will definitely work but you’ll get an older version of rust and theres still no cargo binary out there. I’ve got a long flight to Berlin on sunday, perhaps I’ll get some time at another attempt to cross-compile the cargo bootstrap. Haven’t had any time on it this week

[gurry]

Thanks @eeyun

I’m running into some problems while installing pkgsrc on my Solaris 11 machine. Since pkgsrc binaries are not available for this platform, I’m trying to install it from source, but after running the bootstrap for some reason pkgin command does not become available. Maybe something failing during compilation. I’ll fix this problem and then try installing rust with it.

[eeyun]

@gurry make sure after the bootstrap command has been run that the pkgin command exists on your path, let me know if I can help!

@eeyun I’m currently trying to get a Rust compiler working on an OpenSolaris distribution (Schillix to be exact).

What’s the best way to make that work?

Currently downloading packages from https://pkgsrc.joyent.com/ for SmartOS and hoping that they’ll work. I already tried cross-compiling rustc by using (and patching) japaric’s docker container but ran into issues where LLVM does not cross-compile.

[apopiak]

I got the binaries from joyent working (they had weird issues in libunwind), but they don’t contain cargo. Has anyone ported that to Solaris by any chance?

[mcandre]

Hmm, looks like the “rust” package is no longer offered in the latest 2017Q4 repository. Can we revive this package, and hopefully add cargo to it?

[nbaksalyar]

Has anyone ported that to Solaris by any chance?

Hi - sorry for a late reply. Yes indeed, it is ported to Solaris (in fact, there is nothing special about Cargo, the main porting effort goes to its dependencies). The main problem there is to build the stage0 cargo snapshot: the bootstrap process is (or was?) almost undocumented and you’ll have to use special scripts to collect and build Cargo deps without having a Cargo binary in the first place, so the build process is somewhat convoluted.

The bootstrapping script can be found here: https://github.com/dhuseby/cargo-bootstrap - it was written by @dhuseby for Bitrig BSD but it works pretty well for any other OS.

There are also some older snapshots for SmartOS - you might want to try your luck with these: https://twitter.com/nahumshalman/status/785285724262326272

Ok… so - first necrothread and I apologize - but, I DO have some more info on this. I’ve got a couple as-of-yet untested Illumos binaries that I managed to put together several months ago before no longer having time to hack on this.

Personally I’d really love it if someone with the time and energy could use these binaries to get a legitimate pkgsrc definition for Illumos. But I doubt it’s something I’m going to have time to work on for a little while longer.

If anyone would like me to host the cargo and rustc binaries somewhere public (especially if you’ve got the intention to try to use them as the bootstrap for a more recent Rust) just reply to this thread and I’ll get them pushed up into s3 or something.

[eeyun]

Actually ignore me. For anyone that stumbles on this thread. As of pkgsrc release 2018Q2 rust 1.27.0 is now available on illumos!
