Is there a problem with my trust Cross compiler

I first encountered Trust today and encountered this error when I wrote the first 'hello world' based on official documentation

root@VM-4-14-ubuntu:~/homemadeOS/OSfoundation/rustExercise/demo# rustc src/main.rs 
error: linking with `cc` failed: exit status: 1

error: aborting due to previous error

this is my project Directory
(I created the project directory using the method of cargo new demo bin)

Cargo.lock  Cargo.toml  src/  target/

After I execute some commands, I will generate some unknown files

root@VM-4-14-ubuntu:~/homemadeOS/OSfoundation/rustExercise/demo# ls
Cargo.lock                    main.main.bd587cf2a5a1bf91-cgu.0.rcgu.o  main.main.bd587cf2a5a1bf91-cgu.3.rcgu.o  src
Cargo.toml                    main.main.bd587cf2a5a1bf91-cgu.1.rcgu.o  main.main.bd587cf2a5a1bf91-cgu.4.rcgu.o  target
main.4x73ygqb52ry76yh.rcgu.o  main.main.bd587cf2a5a1bf91-cgu.2.rcgu.o  main.main.bd587cf2a5a1bf91-cgu.5.rcgu.o

I guess this may have something to do with reporting an error

about the "/tmp/rustcVEWi2j/symbols.o"

I tried using the file /tmp/rustcVEWi2j/symbols.o command and this occurred

root@VM-4-14-ubuntu:~/homemadeOS/OSfoundation/rustExercise/demo# file /tmp/rustcVEWi2j/symbols.o
/tmp/rustcVEWi2j/symbols.o: cannot open `/tmp/rustcVEWi2j/symbols.o' (No such file or directory)

So I want to know whether this error is due to my wrong Cross compiler

Maybe you should be compiling the demo project with

cargo build

This will call rustc in the background and do the linking for you.

for execute you have two alternatives:

cargo run

or

search the binary in the target folder (that will be generated after compiling) and execute it.
