"undefined reference to" error
by Darrell Anderson 04 Jan '12

04 Jan '12

Slowly, ever so slowly, I'm trying to learn C++. I have this Big Fat Book on my desk and almost every day I read, tinker, and study code. While trying to compile koffice I ran into these fatal errors: ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::~Parser()' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::statement() const' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::parse(QString const&)' ../../.libs/libkexidb.so: undefined reference to `tname(int)' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::Parser(KexiDB::Connection*)' ../../.libs/libkexidb.so: undefined reference to `KexiDB::Parser::query()' If the g++ error lists a line in a *.cpp file, then usually the "undefined reference to" error means a missing header file that declares the namespace or function. In this particular error, g++ listed a static library. From what I've read, this means something is awry in the linking process and not in the code itself. Am I on the right track? If not then please set me straight. :) If yes, then how do I fix the error? I presume something in the Makefiles? Does the error provide me clues as to where I need to fix the problem? Trying to learn! Thanks! Darrell

Minimal KDialog
by Darrell Anderson 03 Jan '12

03 Jan '12

I notice some apps use a stripped or minimal KDialog rather than the full blown KDialog that supports bookmarks and configuration. Examples include Ark and KFileReplace. Is there a user way to configure those apps to use the full KDialog? Or does the source code need modification? Is there a way to search the source code to find which apps use this minimal KDialog?

Forcing Trinity To Crash
by Darrell Anderson 02 Jan '12

02 Jan '12

Oddball request, but I need a way to crash Trinity. :) I created bug report 769 (http://bugs.pearsoncomputing.net/show_bug.cgi?id=769). Basically, on one particular computer I am able to get Ark to crash consistently. Yesterday I started tinkering with building my packages with separate debug packages rather than building the debugging symbols into one package. I figure outside of the devs and packagers most end-users are not interested in that support. :( Today on that same computer I installed new packages for kdelibs, kdebase, and kdeutils: six packages instead of three. Now I can't get Ark to crash. 1. I don't pretend to understand the nuances of debugging symbols, but by splitting the debug symbols into a separate package, could I have resolved the bug? Does that make sense? 2. I need a way to crash something in Trinity so I can test my split packages. I have browsed through the bugzilla and could not find anything that was repeatable here. Would someone please suggest a way to test the Dr. Konqi crash handler so I can generate a backtrace? My request is not related to point 1 above --- I just want to test whether my new package scheme is working and I need a way to verify I can generate a backtrace in Trinity. Perhaps there is a built-in easter egg or something that can do just that? Darrell

tqt3/qt3, libart

In Git, what is the difference between tqt3 and qt3? What is dependencies/libart and when would I build that package? Darrell

TDE-3.5.13 - Base system completed
by Baho Utot 28 Dec '11

28 Dec '11

I have now successfully packaged the following for Arch Linux with the PKGBUILDs and some bash scripts for building this set. They will need to be built using a clean chroot see this link for explaination: https://wiki.archlinux.org/index.php/DeveloperWiki:Building_in_a_Clean_Chro… The PKGBUILD script will show the dependencies for each package. I will moving on to the applications shortly, I need a little break ;) If anyone is interested i have placed the scripts here: git clone https://github.com/baho-utot/trinity.git until they can be incorperated into the tde-packaging repo. # # Dependencies # qt3 - autotools - complete tqtinterface - cmake - complete arts - cmake - complete dbus-tqt - cmake - complete dbus-1-tqt - cmake - complete # # Desktop # kdelibs - cmake - complete kdebase - cmake - complete kdebindings - not needed - not needed kdeaccessibility- autotools - complete kdeutils - autotools - complete kdemultimedia - autotools - complete kdeadmin - autotools - complete kdeartwork - autotools - complete kdegames - autotools - complete kdetoys - autotools - complete kdeedu - autotools - complete kdepim - cmake - complete kdesdk - autotools - complete kdeaddons - autotools - complete kdevelop - cmake - complete kdewebdev - cmake - complete kdegraphics - cmake - complete Thanks to everyone

kdemultimedia and akode
by Bruce Dubbs 28 Dec '11

28 Dec '11

I wanted to share a few things about kdemultimedia. First I didn't see akode in the repository, but I have a copy of akode-2.0.2. With a small patch to allow it to build with gcc-4.6.1, I was able to install it with: sed -i "s/#include <iostream>/&\n#include <cstdlib>/" \ akode/lib/auto_sink.cpp sed -i 's@#include "../lib/decoder.h"@&\n#include <cstdlib>@' \ akode/akodeplay/akodeplay.cpp sed -i "s/<assert.h>/&\n#include <string.h>\n/" \ akode/lib/player.cpp sed -i "s/<iostream>/&\n#include <string.h>\n/" \ akode/lib/magic.cpp ./configure --prefix=$TRINITY_PREFIX --without-ffmpeg make If you want the patch (2 lines change), I'd be glad to send it. I should probably put that and the seds above into one patch. ----- Second, I was able to build kdemultimedia, but one module had a problem picking up where tqt was located. The following did work for me: cp -v /usr/share/aclocal/libtool.m4 admin/libtool.m4.in cp -v /usr/share/libtool/config/ltmain.sh admin/ltmain.sh sed -i -e "s@/usr/include/tqt@$TRINITY_PREFIX/include/tqt@" \ admin/acinclude.m4.in make -f admin/Makefile.common sed -i -e "s@^gentable_LDADD.*$@& -L$TRINITY_PREFIX/lib@" \ noatun/library/Makefile.in ./configure --prefix=$TRINITY_PREFIX \ --with-qt-dir=$QTDIR \ --enable-closure \ --with-vorbis \ --with-alsa \ --with-audiofile \ --with-flac \ --with-akode \ --with-extra-includes=$TRINITY_PREFIX/include \ --with-extra-libs=$TRINITY_PREFIX/lib:$QTDIR/lib && #--with-xine \ #--with-cdparanoia \ #--with-lame \ #--with-theora \ #--with-gstreamer \ #--with-kscd-cdda \ make I still need to add some more prerequisites and test some more, but the PKGBUILD for kdemultimedia indicated akode wasn't available, so I thought I'd share. -- Bruce

Trinity Application Descriptions
by Darrell Anderson 27 Dec '11

27 Dec '11

I created an etherpad containing TDE application descriptions. I extracted much of the information from Helpbook abstracts and then massaged the information accordingly. The extraction process was not fluid or easy to read, even after cleanup. I suspect a few apps are missing from the list. The descriptions are more or less grouped the same as the T-Menu. Everybody please feel free to edit the list as needed. Tim, Calvin: In my web site improvement suggestions I recommended an applications description page. Ideally, we should have full web pages for certain apps, but this list will provide a nice start. Darrell

Konqueror does not always update file pane
by Darrell Anderson 27 Dec '11

27 Dec '11

Is anybody else experiencing this? For example if I manage files outside of Konqueror, the file pane does not automatically update. I have to refresh the pane to see the changes. Is there a config setting that could affect this? Darrell

Packaging naming with GIT
by Darrell Anderson 25 Dec '11

25 Dec '11

With SVN I used a package naming scheme based upon the previous official release number and SVN version: kdebase-3.5.12-125202-i486-1.txz With the official tarballs the package name excluded the SVN version: kdebase-3.5.13-i486-1.txz I expect to continue that naming scheme with official release tarballs, although the version numbers change: kdebase-r14.0-i486-1.txz Enter GIT. GIT uses a weird hash number for each patch version. Is there a more straightforward version number? Or will I have to start naming GIT builds using a date and time scheme? kdebase-20120101_2200-i486-1.txz More generally, should we adopt a common package naming scheme, as much as possible within the limitations of each distro's package naming conventions? Might be nice if all of us use a somewhat similar naming scheme. Ideas? Comments? Darrell
