Build failed. Cannot link clang.dll

[zanaviska]

So I tried to install opencv-rust, but error cannot find -lclang.dll happened.
Opencv was build from source. About ENV

cargo run cannot build opencv because it cannot link clang.dll(which I honesty couldn't find myself). clang was downloaded from winlibs.com. llvm and installed with command choco install llvm

1. Windows
2. OpenCV was installed from source with mingw/g++ compiler
3. OpenCV version: 4.5.4
4. rustc version 1.56.0
5. output of the command

   RUST_BACKTRACE=full cargo build -vv

Here are my compilation steps:

• Using llvm-mingw, I downloaded the binary package from https://github.com/hwoy/llvm-mingw/releases/

• Copy llvm-cumMinGW64-msvcrt\lib\libclang.dll.a to $mingw64/lib,for example I use MSYS2, copy to msys64\mingw64\lib or add it to PATH

• Install MSYS2

• Download the following packages with the pacman tool (use the pacman -S package_name command):

  • mingw-w64-x86_64-gcc
  • mingw-w64-x86_64-clang
  • mingw-w64-x86_64-lld
  • mingw-w64-x86_64-gdb
  • mingw-w64-x86_64-make
  • mingw-w64-x86_64-polly
  • mingw-w64-x86_64-compiler-rt

  This way, you will get the Clang compiler which is built with mingw-w64 and has paths and macros that correspond to this toolchain.

• For subsequent compilation errors, you can find solutions in issues
