Can this application be compiled on Windows 7?

[GamerHammer2K4F647Ultimate]

Since I am running Windows 7, and there's no pre-built binaries for zbar-23.92 or above(I am tryna to decode a qr-code with binary data inside), I tried compiling, only to see that it can only be compiled on Linux.

Can it be compiled on Windows 7 without WSL?

Well, here are the steps.

1. download and install VS 2019 from Microsoft Visual Studio site
2. install cmake
3. install git, then clone vcpkg source code and install libiconv, libpng and zlib on D disk

   
   d:
   cd /
   git clone https://github.com/microsoft/vcpkg.git
   cd d:/vcpkg
   bootstrap-vcpkg.bat

vcpkg integrate install

vcpkg install libjpeg-turbo libjpeg-turbo:x64-windows vcpkg install libpng libpng:x64-windows vcpkg install libiconv libiconv:x64-windows vcpkg install zlib zlib:x64-windows

4. clone zbar source code

d: cd / git clone https://github.com/mchehab/zbar.git

5. download [zbar-cmake-msvc.zip](https://github.com/mchehab/zbar/files/7209645/zbar-cmake-msvc.zip) and extract all files and folders to the `zbar` root folder (d:/zbar).
6. use `cmake` generate the build environment.

d: mkdir d:/zbar/build cd d:/zbar/build cmake .. -DCMAKE_TOOLCHAIN_FILE=D:/vcpkg/scripts/buildsystems/vcpkg.cmake

7. open `Visual Studio 2019 Developer Command Prompt`, then build zbar with it.

d: cd d:/zbar/build devenv zbar.sln /Build

8. done

Hello, is it possible compile for win32?

[ssrlive]

Yes https://github.com/ShadowsocksR-Live/zbar/blob/master/README-windows.md#building-with-cmake-on-windows @EliaTolin

[EliaTolin]

Yes https://github.com/ShadowsocksR-Live/zbar/blob/master/README-windows.md#building-with-cmake-on-windows @EliaTolin

Yes but i need the version x86, not x64. Is it a fork with x86?
