Executing multirust override nightly-2016-04-05 then calling cargo build also does not work :(

hansihe · 2016-04-18T05:30:02Z

Thank you for the report.

Could this be a variant of rusterlium/erlang_nif-sys#3?

I am not at a computer at the moment, so I can't give an exact command to run, but could you try the command listed in the issue to see if compilation works?

Adding this to my nif.rs made it compile:

Now I'm getting:

Seems like it's looking for target/debug/librustler_test.so not target/debug/librustler_test.dylib in the call to :erlang.load_nif(path, 0).

hansihe · 2016-04-18T06:13:26Z

That's strange, demo.exs uses a wildcard to find the file. Is there a .so in the target/debug/ directory by any chance?

brendanzab · 2016-04-18T06:17:22Z

OSX uses the .dylib extension for dynamic libs. Looks like :erlang.load_nif only looks for .dll or .so. :(

hansihe · 2016-04-18T06:22:40Z

I am fairly certain :erlang.load_nif supports loading .dylibs as well. Could you try changing these three lines in your demo.exs to this?

path = "target/debug/librustler_test"

Edit: yeah, this won't do anything.

brendanzab · 2016-04-18T06:22:44Z

Trying to do some googling to see how to link to dylibs with erlang, but not coming up with anything... rust-lang/cargo#1970 looks related...

hansihe · 2016-04-18T06:23:49Z

For reference, here is a library that loads a NIF. It seems to be supported on Mac.

https://github.com/elixircnx/comeonin/blob/a158b18e52fac1adc715d9b0f7cd6efe6336b73b/lib/comeonin/bcrypt.ex#L55

hansihe · 2016-04-18T06:25:01Z

Ah, if that issue is related, the comeonin guys might be changing the extension?

brendanzab · 2016-04-18T06:27:10Z

By the way, here is my target/debug folder:

$ ls target/debug
build                      examples                   librustler_test.dylib.dSYM
deps                       librustler_test.dylib      native

hansihe · 2016-04-18T06:29:58Z

You could try copying librustler_test.dylib to librustler_test.so to confirm the issue

brendanzab · 2016-04-18T06:32:51Z

Wooo!

$ cp target/debug/librustler_test.dylib target/debug/librustler_test.so
$ elixir demo.exs
9290

brendanzab · 2016-04-18T06:33:21Z

I wonder if we could create a build script to do that...

hansihe · 2016-04-18T06:40:34Z

In the longer term, it would be nice to make :erlang.load_nif support loading .dylibs on macs

This file seems to handle library loading on unix systems. It seems to just append .so to the library name.

turboladen · 2016-10-17T06:00:45Z

FWIW, I've been trying for a few hours now to get Rustler working with Rust 1.12 and have been running into the same issue (ld: symbol(s) not found for architecture x86_64). I also tried dropping Rustler and just using erlang_nif-sys, but ended up with similar build errors. I gave up, then came back after a couple hours away from the computer to try to get it to work again, ran into the same problem again, then found this ticket.

The fix seems to be to use the link_args feature, but then that implies that Rustler doesn't work unless you're using nightlies. Is that correct?

hansihe · 2016-10-17T06:07:32Z

You should be able to build it on stable using the following command:

cargo rustc -- --codegen link-args='-flat_namespace -undefined suppress'

Could you try it out and see if it works?

hansihe · 2016-10-17T14:25:17Z

I implemented a fix for rustler_codegen in 64351d4.

Because I do not have a Mac available, the fix is untested. If anyone with a mac could test it by running mix test in the /test/ directory, it would be greatly appreciated.

turboladen · 2016-10-17T16:29:32Z

I think that did the trick, @hansihe! Where does the --codegen flag come from? Thanks!

hansihe · 2016-10-17T16:37:08Z

@turboladen --codegen is a rustc flag which is documented here.

Did I understand the question correctly?

turboladen · 2016-10-17T16:38:58Z

Did I understand the question correctly?

I think so, as that seems to have fixed my compile problem. I asked about the flag just because I hadn't come across it before and wanted to learn about it.

turboladen · 2016-10-17T16:40:55Z

If anyone with a mac could test it

I cloned the repo (I'm at git ref 12577b96222032738594fa3623313f6c90645abe). I'm getting a failure; here's the whole output:
