Statically link the VCRuntime when using the MSVC toolchain

By default, Rust requires programs to deploy vcruntime140.dll (or equivalent) when redistributing binaries. This crate statically links the library instead.


Add this to your Cargo.toml:

static_vcruntime = "2.0"

And in your build script:

fn main() {

That is all. Then when you build a release binary, the runtime will be statically linked:

cargo build --release


If you have problems then you may need to clean the build directory before rebuilding:

cargo clean

If all else fails then, in the same directory as your Cargo.toml, create a folder called .cargo. In that folder create the file config.toml and add the following:

[target.'cfg(all(windows, target_env = "msvc"))']
rustflags = ["-C", "target-feature=+crt-static"]

This makes it easier to override the defaults.


Use dynamically linked ucrt with a statically linked vcruntime.
