32 bit build on Windows

[DanielO]

Hi, I'm trying to build a 32 bit VST version on Windows (because another plugin I want to use is 32 bit only) and I've not managed it yet.

I installed mingw x86_64-12.2.0-release-posix-seh-msvcrt-rt_v10-rev2.7z (plus cmake & ninja). I also had to copy windres to x86_64-w64-mingw32-windres.exe so it gets found.

I get the following error:

PS C:\temp\noise-suppression-for-voice-1.03\build> & cmake -Bbuild-mingw64 -GNinja -DCMAKE_TOOLCHAIN_FILE='toolchains/toolchain-mingw64.cmake' -DCMAKE_MAKE_PROGRAM='C:/temp/ninja.exe' -DCMAKE_BUILD_TYPE=Release ..
CMake Warning (dev) at CMakeLists.txt:1 (project):
  Policy CMP0048 is not set: project() command manages VERSION variables.
  Run "cmake --help-policy CMP0048" for policy details.  Use the cmake_policy
  command to set the policy and suppress this warning.

  The following variable(s) would be set to empty:

    CMAKE_PROJECT_VERSION
    CMAKE_PROJECT_VERSION_MAJOR
    CMAKE_PROJECT_VERSION_MINOR
    CMAKE_PROJECT_VERSION_PATCH
This warning is for project developers.  Use -Wno-dev to suppress it.

Is there a known working compiler that I can test against?

Thanks.

The mingw is known not to be working. So you are left with MSVC:

cmake -B build-x32 -A Win32
cmake --build build-x32 --config Release --parallel

Thanks.

I found if I installed Visual Studio with the "C++ Application" install ran the 'x86 Native Tools Command Prompt for VS 2022' command prompt I could then build with just 'cmake -GNinja ..'

Do you think it's worth updating the README with such a hint?
