Rust program requires the libusb DLL to be present even though it was statically linked
When using Rust to build a program that depends on libusb, there are two ways to link the libusb library: static linking and dynamic linking.
Static linking means that the libusb code is directly included in your Rust program, and you don't need the libusb DLL to be present at runtime. In this case, your program should not require the libusb DLL to be present.
Dynamic linking means that your Rust program relies on the libusb DLL at runtime. Even if you statically link the libusb library during the compilation process, your program will still require the libusb DLL to be present when it is executed.
If your program is requiring the libusb DLL to be present, it suggests that you might be dynamically linking the library. To ensure that your Rust program is statically linked and doesn't require the libusb DLL, you can check the following:
Make sure you have the
static
feature enabled for the libusb crate in yourCargo.toml
file:toml[dependencies]
libusb = { version = "0.3", features = ["static"] }
Confirm that you are building the Rust program with the
--features static
flag to explicitly enable static linking:bashcargo build --release --features static
By explicitly enabling static linking with the static
feature and building your program with the --features static
flag, you should be able to ensure that the libusb library is statically linked and your program does not require the libusb DLL to be present.
