AIUI from Paolo, the intention is to deprecate and eventually stop supporting "in-tree" builds, so that the only option is building in a separate build directory. I thought we should probably mention that in the 5.0 changelog, so I wrote up some text:
https://wiki.qemu.org/ChangeLog/5.0#Build_Information Suggestions for changes/comments etc welcome. (One thing we will need to fix before we can do separate build tree is the Coverity Scan build process, which (a) does an in-tree build (b) can't be easily switched to a builddir because all the source paths get baked into the scan results and moving to a builddir changes them all...) We could also make configure actively warn if used in the source tree. thanks -- PMM
