How to build libc in dylib?

[baoshan]

Is it possible to build libc in dylib format? Right now it would be built into rlib by default.

I tried to add this in libc’s Cargo.toml:

[lib]

crate-type = [“dylib”]

But get these errors:

error: #[panic_handler] function required, but not found

error: language item required, but not found: eh_personality

error: aborting due to 2 previous errors

Is the libc designed not to support “dylib” mode? Or is there more change need to be made to make it work?

Thanks,

Baoshan

Rust’s libc crate is more like C’s .h file. It doesn’t do anything, it just tells the compiler that certain functions exist elsewhere.
