how to fix it?
thanks!

[zonyitoo]

linked-hash-map 编译不过

Ref: contain-rs/linked-hash-map#31

[zonyitoo]

linked-hash-map 已Fixed，但接下来的问题是memmap不能编译，正在等它放到crates.io上。

Ref: danburkert/memmap-rs#17

[luckypoem]

hi.
我在~/shadowsocks-rust目录里运行cargo build，仍然遇到同样的错误，我看了https://github.com/contain-rs/linked-hash-map/issues/31，它说“Fixed in version 0.0.7.”，我如何把linked-hash-map升级到0.0.7?

[zonyitoo]

cargo update 就好。
另外目前还差memmap的升级，先等它把新版publish上去

已重现，的确是有问题，这里显示有几个crate依赖了kernel32，我看看是哪个的问题

[zonyitoo]

请 git pull 之后执行 cargo update && cargo build，编译应该会通过。

不能干脆删掉linked-hash-map这个组件吗

[zonyitoo]

error: #[feature] may not be used on the stable release channel

你的错误里就告诉了你原因了，要用Rust Nightly，不能用stable。
即使我删掉linked-hash-map也是不行的，因为coio也必须使用Nightly。

[luckypoem]

hi。
我怎么使用nightly版的程序？

[luckypoem]

hi.
知道怎么用rust nightly了。先卸载，再装nightly版的rust.不过虽然build成功，但target目录里并未出现sslocal和ssserver文件：

怎么回事呢？

[zonyitoo]

在debug里面，你如果加--release的话这里还会多出一个release文件夹。
另外，你可以去用multirust来装多个rustc版本。

[zonyitoo]

另外，你也不用直接去target/debug里面去运行的，直接用

cargo run --bin sslocal

就好

[luckypoem]

[zonyitoo]

你的是什么系统，什么架构？x86的么？

[zonyitoo]

更新之后还是会出现kernel32-sys的问题，找到是因为time没有更新的原因。

[zonyitoo]

32位目前是有Bug的，协程库在32位下跑会有问题（https://github.com/zonyitoo/coio-rs/issues/12）。
下面的那个问题就是我讲的在time里面引用的kernel32-sys版本冲突的问题。

[luckypoem]

hi.
那如何解决“在time里面引用的kernel32-sys版本冲突的问题”？
要等https://github.com/rust-lang-deprecated/time/的作者更新`kernel32-sys` in dependencies吗

[zonyitoo]

嗯，就他没更新，而其它的人都更新了，导致同一个项目里链接了同一个crate的不同版本

[luckypoem]

hi.
这位retep998似乎不愿更新，那现在怎么解决kernel32-sys版本冲突的问题？我在:~/shadowsocks-rust／里运行cargo build怎么就解决了kernel32-sys版本冲突的问题呢？怎么把“ ~/shadowsocks-rust／里运行cargo build就解决了kernel32-sys版本冲突的问题”的思路固定下来？

[zonyitoo]

time 已更新 kernel32-sys 的依赖。

[luckypoem]

HI.
我上面就是cargo update，然后cargo build后所显示的内容。
不明白怎么回事，才解决 kernel32-sys v0.1.4的问题。怎么又冒出一个ws2_32-sys问题？
这行“Adding ws2_32-sys v0.2.0”，不能想办法去掉它吗

[zonyitoo]

不能，因为依赖的库里面各自依赖了同一个库的不同版本。

[luckypoem]

那这问题咋解决呢？

[zonyitoo]

miow 和 net2 更新没有同步，net2 先更新了，等几天吧。
昨天还没更新的。

[luckypoem]

hi.
还没更新吗
