[GitHub] [incubator-teaclave-sgx-sdk] xu-cheng opened a new pull request #260: Fix switchless sample code
xu-cheng opened a new pull request #260:
URL: https://github.com/apache/incubator-teaclave-sgx-sdk/pull/260
In order to use the switchless feature of the SGX, the app binary needs
to be linked with the following flags.
```
-Wl,--whole-archive -lsgx_uswitchless -Wl,--no-whole-archive
````
Noted that there is currently no proper way to pass custom link flags to
all the binaries in a cargo project. As such, the `link_args` macro need
to be set for each of Rust files with `main` methods.
