No Windows cross-compiler found for

Error message

No Windows cross-compiler found for ${target.arch}. Install Microsoft C++ Build Tools on Windows, or set ${target.envCompiler} to a MinGW-compatible compiler.

What it means

Environment-validation error in buildWithMingw: resolveMingwCompiler found no usable MinGW-compatible cross-compiler (e.g. aarch64-w64-mingw32-gcc) for the target arch on this machine. The mingw build path cannot proceed at all, so the script tells the user to either install MSVC Build Tools on Windows or point the arch-specific CC env var at a compatible compiler.

Solutions

  1. Install Microsoft C++ Build Tools on Windows, or set the indicated environment variable to a MinGW-compatible compiler.
