"load" command in tiger_import

[John L. Poole]

The bin/tiger_import shell script has this line:

# Generate an SQL stream to feed into the sqlite3 binary.
# Start by loading the helper libs and initializing the temporary
tables
# that will hold the TIGER data before ETL.
(echo ".load $HELPER_LIB" && \

When I run it on my Gentoo system, I get:

Error: unknown command or invalid arguments: "load". Enter ".help"
for help
memory

"man load" does not return anything on my system; moreover, in the
Unix in a Nutshell book, there is not listed in the basic commands or
the index "load".

I've concurrently posted on the Gentoo Forum (http://forums.gentoo.org/
viewtopic-t-820663.html) my question, but it seems as though "load" is
not a common command and merits documentation.

Any suggestions on what command I should use, or is there a library I
need to add to my environment, to get the tiger_import script to not
fail on the above line?

It was pointed out to me that ".load" is a sqlite command, not a shell
command. Thus, i've determined that the error message occurs because
my sqlite does not support ".load"; I'll have to go back and read the
installation instructions, I must have missed a point or there is a
version issue at play here.

I suspect you do not have SQLite compiled enabling dynamic loading of
extensions.

Which version of SQLite are you running?

Yup, I did not heed the note:

NOTE: If you do not have /usr/include/sqlite3ext.h installed, then
your sqlite3 binaries are probably not configured to support dynamic
extension loading. If not, you must compile and install SQLite from
source, or rebuild your system packages. This is not believed to be a
problem on Debian/Ubuntu, but is known to be a problem with Red Hat/
CentOS.

I use Gentoo and had accepted the default when installing dev-db/
sqlite. I've re-installed dev-db/sqlite turning on the "extensions"
keyword (adding "dev-db/sqlite extensions" to my /etc/portage/
package.use file) and the error message "unknown command or invalid
options" disappeared.

Aside: now there's another error: Error: bin/../lib/geocoder/us/
sqlite3.so: undefined symbol: ceil
memory
and I'll revisit my installation to double check that I did not
overlook something else and then if I do not solve this issue, create
a new thread.
