Can you be more specific about what the current configuration script in SQLite lacks that aarch64 needs? SQLite has very few dependencies, to the point that a configure script is almost superfluous. I really dislike changing autoconf versions since any autoconf upgrade results in a massive change in the generated "configure" script, which is annoying to audit before each release, and which results in exceedingly large and uninstructive diffs between successive versions. Here is an example to clarify the latter point: http://www.sqlite.org/src/vdiff?from=version-3.7.15&to=version-3.7.16 shows all source code differences between SQLite version 3.7.15 and 3.7.16. This is a large but manageable diff. Had we changed autoconf versions in between those two releases, the diff would have been many times larger, to the point of being unmanageable large, but would not convey any new useful information. So, we need a compelling reason to update autoconf. If you think this is something that needs to be done, then you need to make your case. You say that the current version of autoconf used by SQLite "prevent[s] its being built". That is not strictly true. It might make it less convenient to build on 64-bit ARM. It might mean that you need to rerun "autoconf" before building on ARM. It might mean that you need to use a technique other than "./configure; make" to build. But it does not prevent SQLite from being built. And 64-bit ARM is still an obscure architecture. In my estimation, the inconvenience to everyone of an massive diff between releases outweighs the benefit of being easier to build on an obscure architecture. You (or anyone else) are welcomed to argue to the contrary, of course. > Would it be possible to migrate sqlite to new version of autoconf? > Thanks for answer, > Jan Stanek > -- D.
