I am trying to create a static executable with Rust. I am not trying to statically link a particular library, I am trying to create a executable which does not use dynamic linking at all. I have the following (otherwise working) test:
$ cat hello.rs
fn main()
{
print!("Hello, world!\n");
}
$ rustc hello.rs -o hello
$ file hello
hello: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV),
dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, [etc]
Note the dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2
. Static executables have statically linked
instead. (And in my case corrupted section header size
, although I would be pleasantly astonished if I can convince Rust to replicate that.)
What options do I need to pass to rustc
to get it to generate a actual static executable (for concreteness: one which even file
agrees is statically linked).
Since Rust 1.19, you can statically link the C runtime (CRT) to avoid this very common situation on Windows:
The program can't start because VCRUNTIME140.dll is missing from your computer. Try reinstalling the program to fix this problem.
Add this to your .cargo/config
file, using the appropriate target triple for your platform:
[target.x86_64-pc-windows-msvc]
rustflags = ["-C", "target-feature=+crt-static"]
An alternative to editing .cargo/config
is to pass -C target-feature=+crt-static
to rustc by hand.
