This page has a sub-page for each recent release series listing platforms on which Xapian has been reported to have built and passed "make check". It will probably work on many more platforms - lack of an entry here shouldn't be assumed to mean it won't work, just that we've not had any reports. Please feel free to add new entries and update existing ones (please note if you didn't build and run "make check" on all components). If it doesn't currently work on your platform, please send a patch, or send us a log of the failures.
We have automated builds on all the platforms we can get access to. If you are interested in running a buildbot client, please get in touch.
