Compiling SQLite 2 on Mac OS X 10.5 Leopard (for x86_64)

Mac OS X 10.5 Leopard comes with SQLite v3 bundled. But many times having SQLite v2 can be handy, given that version 3 is not backwards compatible. The hardest step here is to find the download link for version 2 in the official SQLite site. Don't ask me how did I achieve that... I don't remember ;) Fortunately I wrote down the link so you don't have to bother digging the web again :)

So we start with:

$ wget http://www.sqlite.org/sqlite-2.8.17.tar.gz
$ tar -zxf sqlite-2.8.17.tar.gz

The next big problem comes with CFLAGS. The package we are about to install comes with a pre-made configure script that doesn't respects the CFLAGS environment variable when creating the dynamic library. It took me a while but I have the patch for you, too.

After applying the patch to the configure file we can proceed as usual:

$ ./configure --prefix=/usr/local LDFLAGS="-arch i686 -arch x86_64" CFLAGS="-arch i686 -arch x86_64"
$ make

I like to take full advantage of my system so I like to have things working at 64 bits. Just for the case I ever need a tool that won't go 64, I keep a fat binary with both archs 32 and 64. At this point we should check our work:

$ file .libs/libsqlite.0.8.6.dylib
.libs/libsqlite.0.8.6.dylib: Mach-O universal binary with 2 architectures
.libs/libsqlite.0.8.6.dylib (for architecture i386): Mach-O dynamically linked shared library i386
.libs/libsqlite.0.8.6.dylib (for architecture x86_64): Mach-O 64-bit dynamically linked shared library x86_64

Everything seems fine. So we finally install it:

$ sudo make install
