The thing that made me try exchanging libc and libpthread was in fact some hints on other pages, totally unrelated to sqlite. There are tons of links with people having this problem on Apache, ntop, and other bits of software. libtool is always involved. I can't seem to find the page which suggested transposing the order of the libraries, but there was one, which made me transpose them. Perhaps I should try to find what is adding libpthread then, and remove it. In the short term I'd like to get this working on sqlite-3.5.3. But in the longer term, I would hope that Sage updates to the latest sqlite, so it would need to run on that. _______________________________________________ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
