Can't compile substudy
Arthaey opened this issue · 20 comments
I'm trying to update substudy and get it running again after a long time not using it. It used to work! On this same laptop, even, but before I'd upgraded to El Capitan.
I'm on a Mac (El Capitan 10.11.5). I ran multirust update stable and brew install cmake ffmpeg to make sure those dependencies were all up to date. No issues there.
But whether I run cargo install substudy or cargo build, I get the same error message:
/Users/arthaey/.multirust/toolchains/stable/cargo/registry/src/github.com-1ecc6299db9ec823/substudy-0.4.0/src/video.rs:13:20: 13:25 warning: unused import, #[warn(unused_imports)] on by default

Running with --verbose didn't give any more useful output.
Oh, my mistake. I misinterpreted your bug report. The part we need is the list of undefined symbols that should appear somewhere after Undefined symbols for architecture x86_64.
Here's the full stacktrace:

Any ideas?
Sorry for the slow response. This appears to be a problem with the Rust
cld2 bindings, which I also wrote, and how they get linked on a Mac. Could
be related to your C++ compiler somehow.
I don't have access to a Mac, so this may be tricky for me to solve. I'll
try to reproduce this on Linux when I get a chance.

No worries about the slow response; I'm totally getting the support that I am paying for. ;)
Let me know if you're game for a remote-debugging session (chat or screen-sharing) to see if we can figure out what's the deal with the Mac setup?
A coworker of mine who knows Rust suggests that you distribute cross-piled binaries. Is that something you could do?
Unfortunately, cross-compiling for the Mac is tricky, because you need various Apple headers that aren't freely redistributable, I think. Maybe he has a tutorial somewhere?
I do compile MacOS X binaries for some of my programs using Travis CI, but occasionally they don't work, and I have no way to debug them without help from some kind soul who wants to share a screen with me.
OK, it turns out that this was an Xcode 8 compatibility issue affecting my Rust cld2 bindings.
I've fixed this issue (and some Windows build issues) and made a pre-release version of substudy. If you have a moment, could you please test this for me by running:
cargo install --vers 0.4.1-pre.1 substudy
If you don't have a reasonably up-to-date Rust installation, see https://www.rustup.rs/ for instructions. Thank you for the bug report and for any feedback you can provide!

Does that mean there's nothing either of us can do about it?
We may need to run cargo update or upgrade the version of cmake in Cargo.toml.
I ran cargo update, which seemed to be successful, but cargo install --vers 0.4.1-pre.1 substudy still fails with the same cfg(windows) error on my Mac.
I don't see any mention of "cmake" in Cargo.toml, so I don't know how to upgrade the version number, nor to what version it should be upgraded. (FWIW, the version installed on my machine is cmake 3.5.2.)
Below is the output of cargo update, in case it's helpful to you:

I know you're busy, so I'm not expecting a resolution on any sort of "schedule". But I wanted to bump this issue again, so you know there's still Mac interest out there. ;)
Ah, thank you! Have you tried again lately? I updated a whole bunch of the dependencies of substudy sometime within the last couple of months, and there were Mac build fixes in there, IIRC. I really ought to get out my Mac and check. Maybe after the Super Challenge bot is back online. :-/
Yeah, I tried again before bumping the thread. :(
Specifically, I ran cargo update, cargo install --vers 0.4.1-pre.1 substudy, and also cargo install substudy. Same error as before.
Try just cargo install -f substudy; the 0.4.1-pre.1 is older and doesn't have all the build fixes that are in the final 0.4.1. It should build with either XCode 7.3 or 8, as you can see here.
So tonight I decided to run through all the installation steps again. It involved re-installing Rust, plus upgrading cmake and ffmpeg.
And.... :drumroll:
Compiling substudy v0.4.1
Finished release [optimized] target(s) in 134.46 secs
Installing /Users/cmrodgers/.cargo/bin/substudy
:D
Not sure if any of the upgrades were what made the difference, or if the stars were just aligned today, or what. But I'm not complaining. :)
Whoooo!
