It is possible to make an executable with cargo (cargo new ) and create a library by adding the --lib flag (cargo new --lib), but then how would you use the resulting .rlib file (from the library cargo project)? I managed to link the .rlib file as follows: rustc main.rs --ext...
// build.rs use std::process::Command; use std::env; use std::path::Path; fn main() { let out_dir = env::var("OUT_DIR").unwrap(); //下面直接调用gcc生成C库,并未考虑跨平台问题,切切! Command::new("gcc").args(&["src/hello.c", "-c", "-fPIC", "-o"]) .arg(&format!

For cross-building libstd (for use e.g. with miri), it would be great if one could make an rlib-only libstd build. This is because building a dylib invokes the native linker, and that fails when the target architectures is too foreign and/or not supported by the installed C toolchain...
I had to use (I got that hash with a hex editor from libcore-*.rlib): sudo mkdir /rustc sudo ln -s $(rustc --print=sysroot)/lib/rustlib/src/rust /rustc/1f57e4841157d5cbd4c4e22018f93bd1801c98c2 Maybe we can change the lib/rustlib/src/rust path inside the sysroot to either...

To get closer to Swift semantics, we can useRc.Rcis likeBoxbut it can have more than one owner. Here is an updated sample: usestd::rc::Rc;fnmain(){leta=Rc::new([5]);letb=a.clone();println!("{:?}",a);} This compiles. Important changes include the use ofclone().clone()re...
