[GitHub] [incubator-teaclave-sgx-sdk] fredfortier opened a new issue #238: v1.1.2: `InternalBacktrace` in the backtrace feature of tstd
fredfortier opened a new issue #238:
URL: https://github.com/apache/incubator-teaclave-sgx-sdk/issues/238
I'm trying adapt the `error-chain` crate. It relies on the `backtrace` crate which I replaced by the backtrace feature of tstd. I don't know what to do with the hidden `InternalBacktrace` here: https://github.com/rust-lang-nursery/error-chain/blob/44c9240940e974695386cb7b9ab020df1147dbfe/src/lib.rs#L558
```
error[E0432]: unresolved import `std::backtrace::InternalBacktrace`
--> /root/.cargo/git/checkouts/error-chain-cd67bb92899312ae/0503635/src/lib.rs:560:9
|
560 | pub use std::backtrace::InternalBacktrace;
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ no `InternalBacktrace` in `backtrace`
```

I was able port this crate, at least according to my needs.

It seems error-chain needs porting. @fredfortier do you need help with the porting?

I believe there is something wrong.
`InternalBacktrace` is not an std struct, but from here: https://github.com/rust-lang-nursery/error-chain/blob/master/src/backtrace.rs#L16.
I'm not sure what changes did you make to adapt with the SDK. It would be very helpful if you can provide me more details.

@mssun You were right. I confused error-chain backtrace module with the std. I got past this issue but now getting the error below. Like @dingelish suggested, I'm just trying to port the crate.
```

@dingelish Yes, I would appreciate help with the porting.
