Bernd Schmidt <bernds at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|UNCONFIRMED |RESOLVED CC| |bernds at gcc dot gnu.org Resolution|--- |WORKSFORME --- Comment #6 from Bernd Schmidt <bernds at gcc dot gnu.org> --- This PR is not making much sense to me. The autodetection seems right, but you're quoting config/bootstrap-debug.mk, which also contains an override for do-compare, and your configure line does not include an --enable-build-config. So the contents of that file should be entirely irrelevant. A bootstrap with --enable-build-config=bootstrap-debug works for me. Please verify you do not have local changes, ensure you start from a clean build directory, and try again. I suspect some kind of pilot error, so closing for the moment. Feel free to add more information if you still have the issue.
