Why does that need fixing? The AMD64 build *can* execute x86 binaries, whether it is performed on Win32 or Win64. A problem only arises if the AMD64 build assumes that it can execute AMD64 binaries, and it is a cross-compilation. As a consequence, we must never execute the python.exe that we just built during the build process. > My proposal > would allow (eg) 'PCBuild\python.exe' or 'PCBuild\make_versioninfo.exe' to > specified in build processes, with the knowledge it will work, regardless of > what platform it is being run on. No to python.exe, yes to make_versioninfo.exe. make_versioninfo.exe is *always* an x86 binary, so it is always safe to execute on Windows. If you tried to execute PCBuild\python.exe, it would break my builds: I don't *have* x86 binaries in PCBuild when I cross-compile for AMD64. Instead, I've changed the build process to run HOST_PYTHON if that is set, and only fall back to PCBuild\python.exe if it isn't.
