Error when compiling a custom build

Technology zcashd client
1

I am trying to build a build without librustzcash for my own reasons.

I don’t like the rust language and I don’t understand it, but I like zcash and I want to remove rust from it

can you tell me how to fix this?

./build.sh -i

It looks like Zcash is currently pretty far down the pipeline for Rust integration, if you really want to tinker around with Zcash minus Rust you might try using a fork with a much older version of Zcash, like Zclassic.

All of Zcash’s Sapling shielded functionality is built in Rust, as is the “hybrid Sprout” circuit that we moved to at the same time for Sprout shielded functionality. Removing Rust from a current zcashd build would require re-implementing the shielded logic entirely.

Note also that using the pre-Rust (Sprout-only) zcashd versions in a non-Zcash context is not safe due to the counterfeiting bug in the original Sprout circuit parameters; they would need to be re-generated. (It is not possible to use those older parameters with the current Zcash network.)
