can't compile with rust 1.18

[grindhold]

the problem below the line has been resolved by installing a newer cargo version and rust compiler.

---

with

cargo 0.2.0-nightly (efb482d 2015-04-30) (built 2015-04-30)

and

rustc 1.0.0 (a59de37e9 2015-05-13) (built 2015-05-14)

i receive

failed to parse manifest at `/home/grindhold/_git_archive/gobject-example-rs/Cargo.toml`

Caused by:
  expected a value of type `string` for the key `lib.name`

when entering a random string as name, (as nothing depends on the lib we build, it should not matter, right?), i receive this:

Is my setup hopelessly outdated or what am i doing wrong?

[grindhold]

okay, nevermind. rust 1.0.0 is really outdated and i use 1.18 now which ships with my debian testing. however i still only get this far:

To learn more, run the command again with --verbose.
Makefile:30: recipe for target 'target/debug/libgobject_example.so' failed

Is still still an issue related to my compiler version? i find it a bit strange, because gsignal-handler-ids are in fact uint64

[sdroege]

Thanks for reporting, this was caused by an API change in glib-rs

[grindhold]

thanks for fixing!
