I am starting to do the development/testing needed to add Trinity to Linux From Scratch, replacing KDE3. Right now I have a couple of issues I'd like to get clarified.
First, I notice in the dependencies directory, there are several packages:
dependencies/arts dependencies/avahi-tqt dependencies/dbus-1-tqt dependencies/dbus-tqt dependencies/tqtinterface
I have no problems with arts or tqtinterface but I don't see the other three mentioned anywhere. Are these packages required for Trinity? If so, at what point are they required? We do have instructions already in LFS for D-Bus and avahi libraries.
Second, I have had some problems building kdelibs. There were no problems following the instructions for qt3, tqtinterface, or arts, but there were many places in building kdelibs where I had to edit a link.txt file and add -lX11. I am fairly new at using cmake so I'd like to know if there is a way to add this automatically.
My installation of xorg is a little non-standard because the files are in /opt/xorg, but there are appropriate symlinks at /usr/X11R6 and /usr/include/X11. I didn't seem to have a problem with include files.
It would also be useful to know how to set -L/opt/xorg/lib, but that is not critical because I can do essentially the same thing by export(ing) LIBRARY_PATH.
I'll note that LFS has a policy of not using development versions of packages, so for now we need to be able to work with trinity-3.5.13.
Thanks for your help.

The others are required for specific TDE modules/applications only--for example, there is avahi support in kdebase, and knetworkmanager needs dbus bindings. So while modules other than tqtinterface and arts are technically dependencies for certain modules, they are not global dependencies required for *all* TDE modules.

In the CMakeLists.txt file (usually found in the source directory of the failing library/application) look for the lines that start with LINK. Tack " X11" (without the quotes) onto the end of those lines and you should be set. Also, please be sure to let us know which files needed this treatment in a bug report!

AFAIK this is the correct solution for handling non-standard system library locations.

OK, thanks.

Actually I think the problem is on the HowToBuild wikit page. You have:
export PKG_CONFIG_PATH=:/opt/trinity/lib/pkgconfig: /opt/qt/lib/pkgconfig
(split only for email readability)
however, I think it should be:
export PKG_CONFIG_PATH=/opt/trinity/lib/pkgconfig: /opt/qt/lib/pkgconfig: $PKG_CONFIG_PATH
As I already had PKG_CONFIG_PATH set with /opt/xorg/lib/pkgconfig, it made a difference, and the -lX11 flags now appear correctly.

Looks reasonable; Wiki has been updated.
Thanks!

Well that fix wasn't enough. For kdebase, I needed to do:
find -name link.txt -exec sed -i -e 's/-lz/& -lX11/' {} ;
after the cmake command. If I do this, I might as well pass the -L/opt/xorg/lib here too. Hopefully when -14 is released, all these build issues will be solved.
There is also a problem when building kio_nfs.so in that the most recent glibc libraries dropped nfs/nis. For our system, I needed to add /lib/libtirpc.so.1.0.10
I'll have to do some more checking as I see my tirpc.pc file is wrong, but there will need to be some changes in this area.
The good news is that I was able to install and run trinity (through base). It came up cleanly and looks nice. My remaining issues will be to get the instructions right for BLFS.

First, I notice in the dependencies directory, there are several packages:
dependencies/arts dependencies/avahi-tqt
For any app that needs avahi
dependencies/dbus-1-tqt
Substitute the Qt4 backport bus bindings with these for any app that needs it
dependencies/dbus-tqt
Original dbus qt3 bindings ported to tqt
dependencies/tqtinterface
I have no problems with arts or tqtinterface but I don't see the other three mentioned anywhere. Are these packages required for Trinity? If so, at what point are they required? We do have instructions already in LFS for D-Bus and avahi libraries.
Basically, if a kde3 package needed the qt3 one, they now need the tqt one.

There's also R14 coming out in 4 more months :P I remember that I wanted to do BLFS for 3.5.12 (and bringing it up), but the lower autoconf version seemed to be a problem. You'll realized that we haven't fully converted to cmake :-/
Thanks for your help.
