[PATCH v3] configure: warn if not using a separate build directory |
Date: |
Tue, 31 Mar 2020 18:16:06 +0100 |
Running configure directly from the source directory is a build
configuration that will go away in future. It is also not currently
covered by any automated testing. Display a deprecation warning if
the user attempts to use an in-srcdir build setup, so that they are
aware that they're building QEMU in an undesirable manner.

Changed in v3:
- Don't try to predict the future so much, just recommend
a separate build dir
