Building nightly fails

[ltratt]

Although building beta works fine, when I try and build nightly I get this:

$ ./build.sh nightly

error: no matching package named `fs2` found (required by `cargo`)
location searched: registry https://github.com/rust-lang/crates.io-index
version required: = 0.4.1

The particular failing crate varies each time, so it's not really anything to do with fs2. The part of build.sh that's failing is this:

"${build_rust}" "${target}" cargo-patch

which in my checkout is line 500.

I'm not really sure what the root cause is. What seems weird is that, even if I cd to that directory and try and run cargo (either the one built as part of this repo, or the one in /usr/local/bin/) it doesn't seem to download the crate index. I have no idea what's going on, and some hand-hacking hasn't really got me anywhere. I know that @vext01 has also seen this problem; I've tried it with nightlies from the last 3 days, so I don't think it's a one-off.

Hi Sabastien,

I'm going to be needing a rust nightly soon. Any idea how to fix this issue? I also notice the patches seems to need revision too.

Thanks

I was waiting for rustc 1.17.0 to be commited. landry@ did it today.

The patches aren't required for now: the script uses devel/llvm instead of building the embedded LLVM now.

the build of rustc creates a .cargo/config file with vendored directory. It works for building rustc, but not for building cargo. I updated build.sh to remove the file when cargo is built.

[vext01]

Great, thanks. I'll give it a go today.

The current branch is still a bit experimental. I have already built beta and the build for nightly isn't terminated for now.

As usual after a new release, it is recommanded to do a full cleanup: removing build_dir and install_dir before building nightly ; and to have latest stable rust version from ports (rust-1.17.0).

[vext01]

yep, i always start fresh, just to be sure.

Great job:

arrakis> rustc --version
rustc 1.19.0-nightly

Thanks :)
