build.rs fails in dependencies for examples

[johalun]

Hey!
Thanks for this awesome initiative :)

I can build and run separate binaries that links to async-std as extern crate (like the examples in the readme) but I can't run the examples from within async-std.

johannes@jm:~/dev/async-test % rustc -V
rustc 1.39.0-nightly (53df91a9b 2019-08-27)
johannes@jm:~/dev/async-test % cargo -V
cargo 1.39.0-nightly (3f700ec43 2019-08-19)
johannes@jm:~/dev/async-test % uname -a
FreeBSD jm 13.0-CURRENT FreeBSD 13.0-CURRENT r349834+a82ad980c917(dell-fix_iichid-evdev) DELL-NODEBUG  amd64

This is what I get

Any idea what this might depend on?

This seems like a problem building nghttp2, which is a dependency of libcurl, which is a dependency of (among other things) Surf. We recently had some linking issues there, and fixed them in 1.0.2 (moved from static builds to dynamic builds).

If you're using Surf (or Isahc) anywhere in your tree, perhaps try updating it?

I think this is the issue rust-lang/libc#1489
Closing this.
