| Series | [hurd,commited] hurd: Enable x86_64 build script | expand |
I'm observing that build-many-glibcs.py runs can end up with modifications
to the source directory (which later cause problems with updating the
glibc checkout):

What this suggests to me is that the contents generated for
sysdeps/mach/hurd/bits/errno.h depend on the system for which glibc is
configured - which is never appropriate for a file in the source
directory. Either you need separate files for i386 and x86_64, or the
contents need to avoid depending on the architecture, or the file needs to
become purely a build-tree (and installed) file and not checked in.
Hello, Joseph Myers, le mar. 09 mai 2023 21:53:26 +0000, a ecrit: > I'm observing that build-many-glibcs.py runs can end up with modifications > to the source directory (which later cause problems with updating the > glibc checkout): Ah, indeed, kern_return.h happens to be pulling machine-specific headers, but that doesn't matter for the errno.h content. I have thus ruled them out from the comment. Samuel
