Is trackerd running for your session? (check ps -A)

(For dbus activation to work the tracker.service file must be in the 
dbus services directory (on dapper its at /usr/share/dbus-1/services ). 
The conifgure installation installs it at  $prefix/share/dbus-1/services
so you need to either make sure prefix is same as for dbus (usually 
/usr) or manually copy file over. (Dbus was going to add the services 
directory path to its pkgconfig file to resolve problems like these).

If you have manually started trackerd then ignore the above.

If it is running, please send me log file for tracker (should be in 
$Home/.Tracker)

trackerd traps sigint and attempts to close all Db connections before 
exiting. Sometimes if an error occurs it does not respond.

sqlite does not provide full text searching so cannot be used - I wish 
it did although embedded mysql is slightly faster and more memory 
efficient with large DBs.

I could inline the source for mysql in tracker of course but it is 
rather big ):

It seems SQLite is more

We are moving onto mysql 5 where the mysql client package should contain 
libmysqld.a

You might want to check if a mysql 4.1 client package contains a libmysqld.a

You can of course statically link mysqld.a (it is designed for that)

yes that looks right.

Mysql can also use hand coded assembler which makes it even faster if 
you pass additional arguments.

see http://dev.mysql.com/doc/refman/5.0/en/configure-options.html

I recommend :

--without-server
--with-embedded-server
--enable-assembler
--with-client-ldflags=-all-static       --with-mysqld-ldflags=-all-static

Cant comment im afraid - do any other dbus apps work? (try dbus-monitor 
then run trackerd and do tracker-search)

check tables in $Home/.Tracker/data/tracker if they are small in size 
then nothing was indexed.
