Library missing: libra_tsl_verify_dcap
Hadjittofi, Chrystalla
Hello,
I have been able to successfully deploy the pytorch demo with graphene both with and without SGX, however, when I try to execute the confidential workflow I get this error:
I have tried to install this library and did the sgx dcap installation from the beginning to see if I missed something, but I couldn’t resolve the error. I tried finding this library on the web but nothing comes up when searching the exact name so I’m not sure what to do next. Let me know if this is a common error and if there’s a way to resolve it.
Thanks,
Stalo Hadjittofi

You seem to have skipped the following steps described in https://graphene.readthedocs.io/en/latest/tutorials/pytorch/index.html#preparing-confidential-pytorch-example:
```
cd <graphene repository>/Examples/ra-tls-secret-prov
make -C ../../Pal/src/host/Linux-SGX/tools/ra-tls dcap
make dcap pf_crypt
```
The second command generates the required `libra_tls_verify_dcap.so` library (among others). You can use this command in your own flows to build the library. Don’t forget to copy this library in a well-known directory so that it will be found by your build scripts (this is what the last command in the above snippet does)!
