problems

• When compiling a Teaclave project, you may counter an error similar to the following:

  > error[E0152]: duplicate lang item in crate `std`: `panic_impl`.
    |
    = note: the lang item is first defined in crate `sgx_tstd` (which `counter` depends on)
    = note: first definition in `sgx_tstd` loaded from /home/tshepang/work/ntls-enclaves/dataset-hashing/enclave/target/debug/deps/libsgx_tstd-6cdbb9551fc70463.rmeta
    = note: second definition in `std` loaded from /home/tshepang/.rustup/toolchains/nightly-2022-10-22-x86_64-unknown-linux-gnu/lib/rustlib/x86_64-unknown-linux-gnu/lib/libstd-7b2106000b625742.rlib
  

  A likely cause could be using a crate that has std enabled, which conflicts with the std crate of Teaclave. Avoid it by disabling that std feature of that crate. An example of doing so is running the following command, which uses blake3 as an example:

  cargo add blake3 --no-default-features
