I am getting error at step 3, rustc src/main.rs -l multiply.o -L .
Hi,
Firstly thanks for the tutorial. I follow the steps but I got this error at step 3. I am so new in rust and c, and could not solve the problems. However, when I run this ar rcs libmultiply.a multiply.o and then rustc -l static=multiply -L . src/main.rs, it works as expected. Are there any options to run without ar rcs?
