Compiling (for Go) github.com/gwenn/gosqlite

In case you received a compilation error (for example, when fetching the package with `go get`) indicating that the symbol sqlite3_table_column_metadata could not be found, then you're likely linking against a sqlite build that does not implement the full C API that gosqlite is expecting.

(the rest of this guide assumes a Unix-like environment)

One solution would involve stamping out meta.go, and everything that may rely on it.

A most likely simpler solution involves locally building sqlite to include this functionality. To do this in a minimum number of steps, download the 'sqlite-autoconf' tarball from , unpack it, and run:

`CFLAGS="-DSQLITE_ENABLE_COLUMN_METADATA" ./configure`

At this point, the typical `make && make install` process should work as expected to produce the needed library. Since this build of sqlite probably ended up in /usr/local, you'll, at a minimum, need to set cgo's linker environment variable:

`export CGO_LDFLAGS="-L/usr/local/lib -lsqlite3"`

After doing so, rerun the `go get` or `go install` command that had previously failed: hopefully it will now build without error.
