duplicate lang item in crate `sgx_tstd` (which `num_bigint` depends on): `f32_runtime`. #207

Hey all

Upgrading from 1.09 to 1.10 gives this error:

error: duplicate lang item in crate `sgx_tstd` (which `num_bigint` depends on): `f32_runtime`.

Any ideas?

hey there, could i have your Cargo.toml and the output of cargo tree for your enclave? Thanks!

Hi @samsondav, I noticed that the crates under /opt/sgx-world are using sgx_tstd from github, while your enclave directly depends on /opt/rust-sgx-sdk. Could you please try adding a patch to the Cargo.toml shown as below, to let everything depends on your local rust-sgx-sdk?

Hmm, I tried this but it didn't work.

Would it be better if instead of cloning sgx-world locally I just pointed to each github release individually?

dingelish commented 4 years ago

It's really weird. Currently our examples are using the above patch, like this

If your code is open sourced, I can help you fix the build dependencies :-)

samsondav commented 4 years ago

@dingelish I tried adding the dependencies using github directly and it worked. This will be fine for us :)
