kandi X-RAY | cbindgen Summary

cbindgen is a Rust library. cbindgen has no bugs, it has no vulnerabilities, it has a Weak Copyleft License and it has medium support. You can download it from GitHub.

cbindgen creates c/c++11 headers for rust libraries which expose a public c api. while you could do this by hand, it's not a particularly good use of your time. it's also much more likely to be error-prone than machine-generated headers that are based on your actual rust code. the cbindgen developers have also worked closely with the developers of rust to ensure that the headers we generate reflect actual guarantees about rust's type layout and abi. c++ headers are nice because we can use operator overloads, constructors, enum classes, and templates to make the api more ergonomic and rust-like. c headers are nice because you can be more confident that whoever you're interoperating with can handle them. with cbindgen you don't need to choose! you can just tell it to emit both from the same rust library. there are two ways to use

QUESTION

Rust cdylib crate, linking dll to C program in Windows

Asked 2021-Mar-15 at 18:08

I have been trying to compile a simple rust cdylib crate in windows and linking it with a simple c program. Despite all my efforts I fail to link the dll file.

Minimal example

First of all my rustc version is:

I think there are multiple problems here.

You compile the library for a 64bit system (because Rust is x86_64), but you try to link it with 32bit MinGW
Rust is using the MSVC toolchain and you try to compile the C program with MinGW
I am not entirely sure about that, but I think you linked the mycrate.dll.lib incorrectly. According to that answer you should prefix it with l like so: -L -lmycrate.dll.lib

Obviously there are multiple ways to fix that. For example you can install Rust, so that it uses the MinGW toolchain as explained here.

Or you can use Visual Studio to compile your C code. That is what I did, because I did not want to bother with reinstalling Rust (Please correct me if am wrong, but I think there is no easy way to configure both MSVC and MinGW backends, so that one can switch easily between them in Rust).

The steps to compile and link with VisualStudio 2019 are as follows:

Build the Rust project cargo build --release with your 64 bit Rust installation using MSVC
Create a new Empty C++ project
Add main.c and insert your code
In the same directory where your solution file is placed put headers/mycrate.h
Copy mycrate.dll and mycrate.dll.lib into the same directory where your Solution file is placed
Right click the C++ project in VisualStudio and select Properties
Select Configuration=Release and Platform=x64
Add $(SolutionDir)\headers; to C/C++ -> General -> Additional Include Directories
Add $(SolutionDir)mycrate.dll.lib; to Linker -> Input -> Additional Dependencies
Apply all changes and close the properties pane
Build the project in Release mode with the x64 platform

If you build the Rust project in debug mode (e.g. cargo build) you will have to do the same for Debug mode.

I know it is kind of a convoluted process, so let me know if I should make Repo that serves as a demo for that process...

As I said, if you like to build using MinGW, you will have to setup Rust differently as explained here.

After working through your code, you are redefining RustByteSlice.

From Using Imported C Structs and Unions in Swift, you don't need to redefine it as it automatically imports the struct.

The below swift code works.
