It looks like I'm experiencing the same problem demonstrated here, which I guess is an LLVM/Rust-core issue that uses floating point calculations - which aren't allowed when running in the Windows Kernel.
I'm fairly new to Rust and therefore not sure how to handle this properly.
As demonstrated in the link I managed to work around the error by adding the following snippet to my lib.rs:
#[used]
#[no_mangle]
static _fltused: i32 = 0;typo:
recv -> rev
And you can use branch or rev:
warning: dependency (winapi) specification is ambiguous. Only one of `branch`, `tag` or `rev` is allowed. This will be considered an error in future versionsI am trying to create a driver based on this repository. Trying to build the repo without any changes eventually gives me the error in the title.
language item required, but not found: eh_personality
My primary interest is in Windows kernel-mode drivers, and I've just recently started playing with Rust.
In trying to build (either target for) this project using "rustc 1.47.0-nightly (770bd3d1d 2020-08-10)" I get:
error: internal compiler error: src\librustc_codegen_llvm\context.rs:159:13: data-layout for builtin x86_64-pc-windows-msvctarget,e-m:w-i64:64-f80:128-n8:16:32:64-S128, differs from LLVM default, e-m:w-p270:32:32-p271:32:32-p272:64:64-i64:64-f80:128-n8:16:32:64-S128``
and the compiler eventually panics.
Because I'm a complete Rust noob, I have no insight into this whatsoever... even though I've tried to work my way through target definitions and the "data_layout" specification.
Any help would be appreciated.
