I don't know (since I've never needed to build SQLite), but can offer a hint which may help you discover for yourself while waiting for real expert advice. Just before sending, I did check my incoming mail, and didn't see anything from a real expert yet. After running ./configure (without && make), inspect the Makefile and try to find how it runs the compiler, and how it passes options to the compiler. The man page for make is worth reading, but can be confusing. The Makefiles for other software packages that I have to build from time to time are written following the convention that the compiler is invoked using a macro CC, and that options are passed to it using a macro CFLAGS. If you find lines like $(CC) ... $(CFLAGS) ... then you can set a value for CFLAGS by giving an argument to make: make CFLAGS=-Dxxx If you see lines like CFLAGS = $(SOMEFLAGS) $(MOREFLAGS) $(EXTRAFLAGS) then you'll need to be more careful, and work out which of the macros on the right-hand side should be over-ridden by the argument to make. I hope this helps. _______________________________________________ sqlite-users mailing list sqlite-users@mailinglists.sqlite.org http://mailinglists.sqlite.org/cgi-bin/mailman/listinfo/sqlite-users
