error[E0308]: mismatched types - expected raw pointer `*mut u8` during cross compilation #412

Closed Adoni5 closed 9 months ago

Adoni5 commented 1 year ago

Hey guys - I'm trying cross compile into aarch64-unknown-linux. The problem is the bindings seem to expect *mut u8, and are receiving an i8 reference.

Specifically the issue seems to be here in the modified base metadata.

Am I doing something obviously wrong? I'm cross compiling using an altered version of docker/cross

https://github.com/rust-cross/manylinux-cross/pkgs/container/manylinux_2_28-cross. I'm creating a .so to use with a PyO3 package.

Many Thanks Rory
