Recoll KIO slave
================
An experiment with a recoll KIO slave.
Caveat: I am only currently testing this with a production, but very
recent, version of KDE 4.1, and I don't intend to really support
older versions. The most usable aspects work under KDE 4.0 though. As
a reference, my test system is an up to date (2009-01) Kubuntu 8.10.
Usage
=====
Depending on the protocol name used, the search results will be
returned either as HTML pages (looking quite like a normal Recoll
result list), or as directory entries.
The HTML mode only works with Konqueror, not Dolphin. The directory
mode is available with both browsers, and also application open dialog
(ie Kate).
The HTML mode is much more usable than the directory mode at this point
More detailed help/explanations can be found a document accessible
from the slave:
To try things out, after building and installing, enter "recoll:/" in
a Konqueror URL entry. Depending on the KDE version, this will bring
you either to an HTML search form, or to a directory listing, where
you should READ THE HELP FILE.
Building and installing:
=======================
The directory mode is only available with KDE 4.1 and later. This
began under KDE3 and might still be made to work, but I only built
with KDE4 and cmake recently.
The main Recoll installation shares its prefix with the KIO slave,
which needs to use the KDE one. This means that, if KDE lives in /usr,
Recoll must be configured with --prefix=/usr, not /usr/local. Else
you'll have run-time problems, the slave will not be able to find the
Recoll configuration.
Recipe:
- Make sure the KDE4 core devel packages and cmake are installed.
- Extract the Recoll source.
- IF Recoll is not installed yet: configure recoll with
--prefix=/usr --enable-pic (or wherever KDE lives), build and install
Recoll.
- In the Recoll source, go to kde/kioslave/recoll, then build and
install the kio slave:
mkdir builddir
cd builddir
cmake .. -DCMAKE_INSTALL_PREFIX=/usr
make
sudo make install
- You should have a look at where "make install" copies things,
because misconfigured distribution, generating wrong targets, are
frequent. Especially, you should check that kio_recoll.so is copied
to the right place, meaning among the output of "kde4-config --path
module". As an additional check, there should be many other
kio_[xxx].so in there. Same for the protocol file, check that it's
not alone in its directory (really, this sounds strange, but, to
this point, I've seen more systems with broken cmake/KDE configs
than correct ones).
You need to build/update the index with recollindex, the KIO slave
doesn't deal with indexing for now.
Misc build problems:
===================
KUBUNTU 8.10 (updated to 2008-27-11)
------------------------------------
cmake generates a bad dependancy on
/build/buildd/kde4libs-4.1.2/obj-i486-linux-gnu/lib/libkdecore.so
inside CMakeFiles/kio_recoll.dir/build.make
Found no way to fix this. You need to edit the line and replace the
/build/[...]/lib with /usr/lib. This manifests itself with the
following error message:
make[2]: *** No rule to make target `/build/buildd/kde4libs-4.1.2/obj-i486-linux-gnu/lib/libkdecore.so', needed by `lib/kio_recoll.so'. Stop.
