Issue compiling for wasm32 #3

Closed mcaruso85 closed 3 years ago

mcaruso85 commented 3 years ago

Hi,

When I run:

'cargo build --target wasm32-unknown-unknown --package rust_hello --release'

I get:

Executing 'cargo build --target wasm32-unknown-unknown --package rust_hello --release' Compiling libsodium-sys v0.2.6 Compiling syn v0.15.44 error: failed to run custom build command for libsodium-sys v0.2.6

Does this support build for wasm32 ?

Thanks

Hi, unfortunately it's not compatible with wasm because of the dependency on libsodium. AFAIK there is no libsodium-like implementation for wasm. How do you plan to use the library? Maybe we can conditionally remove the key-related features when compiling for wasm.

Hi Fracek,

Thanks for your quick reply. I would like to use this library in a canister for Internet Computer, which requires to compile to wasm. And I would like to be able to sign transactions, so I will need the key features. I was trying to find out if there are crates for signing that can compile for wasm, I'm basically new to rust. Will something like this ed25519-dalek = "1.0.1" work? But I understand this will require a change in the code impl.

Yes I think that I may work. We need to check that all dependencies work on wasm (I don't know how to check for that to be honest). Maybe remove all code depending on libsodium + signing and see what happens? If it compiles then I'm open to change the crypto library we use.

Hi, I can compile to wasm using:

cargo build --target wasm32-unknown-unknown --package rust_hello --release

But I think I will have to fork and see if I can make it work with that library. It will take me sometime.

We can close this issue.

Thanks !
