```
Problem appeared recently to a codebase that I've been working on.
The same problem happen for `samplecode/sealeddate` that has `sgx_alloc` as a dependency. ```sgx_alloc = { path = "../../../sgx_alloc" }```
My code was working a few days ago. Perhaps something recently broke this?

it seems you're still using old rust-sgx-sdk. could you please try the latest codebase?

What’s your steps to build the project. Can you give me a minimal example? Then I can reproduce your issue. Thanks.

Thanks for your reply.@dingelish. I tried to make [helloworld](https://github.com/apache/incubator-teaclave-sgx-sdk/tree/master/samplecode/helloworld) in samplecode directly but got the same error.I'm confused whether is my network problem prevented the patch's download.

Hi，I'm a Rust novice.
How did you download and use the patch to fix it?

My intel driver version is 2.6, I run in hardware mode + docker execution.
The `git log` in my computer is:
```

@RMheng Can you give us more details? Like what version of Intel SDK, Rust version, etc. If possible, you can use the docker to build your first SGX enclave. Thank you so much!

I built the project by referencing to [用硬件模式+docker真实执行](https://github.com/dingelish/SGXfail/blob/master/01.md#%E7%94%A8%E7%BA%AF%E8%BD%AF%E4%BB%B6%E6%A8%A1%E5%BC%8Fdocker%E6%A8%A1%E6%8B%9Fsgx%E7%8E%AF%E5%A2%83%E5%AE%9E%E9%AA%8C)，then I tried the [helloworld](https://github.com/apache/incubator-teaclave-sgx-sdk/tree/master/samplecode/helloworld), the result of `make` is:
```

Check that the patched package version and available features are compatible

what is locked in the Cargo.lock file, run `cargo update` to use the new
version. This may also occur with an optional dependency that is not enabled.

If you couldn't reproce my error, I guess maybe it is my network problem.......
Thanks!

@RMheng , patch refers to the `patch` section like here:
https://github.com/apache/incubator-teaclave-sgx-sdk/blob/66aaa2888992c63137e87adc688ddedab1181056/samplecode/http_req/enclave/Cargo.toml#L18
Basically, it overwrite the entire dependency tree and redirect those dependencies to the patched sources
