问题 I Want To Cross Compile Some Rust Code from Ubuntu to Windows, and receive an error about onexitbegin. Tried to follow various suggestions, but they don't have my specific error message: crt2.o:crtexe.c: (.rdata$.refptr.__onexitend[.refptr.__onexitend]+0x0): undefined reference to `__onexitend' collect2: error: ld returned 1 exit status cargo build --release --target x86_64-pc-windows-gnu Expected to get something built, but it blows up. The output says this: /usr/bin/x86_64-w64-mingw32-ld:

问题 I created a new binary using Cargo: cargo new my_binary --bin A function in my_binary/src/main.rs can be used for a test: fn function_from_main() { println!("Test OK"); } #[test] fn my_test() { function_from_main(); } And cargo test -- --nocapture runs the test as expected. What's the most straightforward way to move this test into a separate file, (keeping function_from_main in my_binary/src/main.rs )? I tried to do this but am not sure how to make my_test call function_from_main from a

问题 I am compiling and building an example program using rust. I chose rustc instead of cargo for compiling because it being a simple personal test project. So far using rustc for compiling and building executable worked fine but when I tried to add an external rand package its giving me this error 1 | extern crate rand; | ^^^^^^^^^^^^^^^^^^ can't find crate This is the full code extern crate rand; use rand::Rng; fn main() { for x in 1..11 { let random_number = rand::thread_rng() .gen_range(1,
