I was trying to setup fortanix SGX EDP and encountered the following after running cargo install sgxs-tools:

Looks like we're trying to build some stuff that can only be built on Linux.

@parthsane can you look into what it would take to make this crate work on Windows?

@jithendaraa Can you try the following:

1. clone this git repository

2. apply this patch

   diff --git a/sgxs-tools/Cargo.toml b/sgxs-tools/Cargo.toml
   index fe25101..d1407c5 100644

3. Run these commands:

   cd sgxs-tools
   cargo install .

@jethrogb I tried applying the above patch to rust-sgx/sgxs-tools/cargo.toml

After I cd into sgxs-tools and run cargo install ., I get the following error:

Updating crates.io index error: could not find . in registry https://github.com/rust-lang/crates.io-index Is there somewhere I'm going wrong and is this something that can't build on Windows 10?

Maybe it's just cargo install

[jithendaraa]

When I ran cargo install, it suggested me to run cargo install --path . or cargo buildinstead.

On running cargo install --path ., I got a bunch of warnings and this error: error[E0432]: unresolved import sgxs_loaders::sgx_enclave_common::dl::os::unix::Library --> C:\Users\jithe.cargo\registry\src\github.com-1ecc6299db9ec823\dcap-ql-0.2.0\src\lib.rs:31:5 | 31 | use sgxs_loaders::sgx_enclave_common::dl::os::unix::Library as Dl; | ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ no Library in sgx_enclave_common::dl::os::unix

Is there something I can do about this?
