I don't think you are doing anything wrong. Let me check for cross-file handling in the meson docs. On my side, I've been using this cross-file for my test builds for the last couple of weeks without issues. I'm using latest meson, but it's been much more reliable for me than the previous method, which required me to occasionally delete the build-32b directory. /Bruce
