This sounds like a transient network problem. Or maybe: do you
access the internet via an HTTP proxy? If so, you need to enter
its IP address under /Tools/Preferences/Databases.

Hmm. set_show_activity_func() is a function that is defined in
lib/src/libset.c, and declared in lib/src/libset.h. It is called
in gui2/gretl.c. Its role is to establish a callback so that
lengthy numerical computations don't appear to make the gretl GUI
"freeze" -- the "show_activity" callback has the effect of
updating the GUI from time to time during such processes.
If set_show_activity_func is being flagged as an undefined symbol,
that seems to imply that libset.c did not get compiled correctly
into an object module within libgretl, or the relevant version of
libgretl did not get installed, or the wrong version of libgretl
is being found by the run-time linker.
Is it possible that the linker is finding some older version of
libgretl instead of the gretl 1.9.3 version?

I presume Samrat means, how to update the fedstl series beyond
what happens to be the latest available via the gretl server.
This is possible, but a little tricky. There is an updater program
in the "utils" subdirectory of the gretl source package. To work
with this you need a C compiler, to build the program, and you
also need to get an "API key" from the St Louis fed:
http://api.stlouisfed.org/api_key.html
The alternatie to rebuilding the full database is just to visit
the FRED system online ( http://research.stlouisfed.org/fred2/ )
and download the specific series you need. You can get these as
CSV (and also Excel format?).

Ubuntu Netbook Edition and gretl 9.3
by Giuseppe Vittucci
Hi,
I installed gretl 9.3 from the source on my netbook with Ubuntu Netbook
Edition 10.04, but the program does not start and returns the following
message on the terminal:
/usr/local/bin/gretl_x11: symbol lookup error: /usr/local/bin/gretl_x11:
undefined symbol: set_show_activity_func
gretl 9.3 instead works well on the other pc I have with Ubuntu 10.04.
Any suggestion?
Thanks.

You can use the "tsls" command. Allow for fixed effects by
including group dummies (see the command "genr unitdum", section
5.4 in the Gretl User's Guide) or by first-differencing.

Updating FRED series in gretl
by Samrat Sanyal
Sir/Madam,
I would like to know how do I update the st.louis FRED database in
gretl.Please send me a solution which does not require any kind of
programming knowledge, as I am not aware of the methods of C++ programming
and use gretl only through GUI menu driven options..
