digikam - error: invalid use of incomplete type 'png_struct {aka struct png_struct_def}'

xterm in TDE black text on black background - where to set defaults?
by David C. Rankin 29 Mar '12

29 Mar '12

All, Is there anywhere in TDE, where default setting for xterm should be set to prevent the black text on black background I currently see when I launch xterm? Should we set a default term color and geometry in XDG somewhere? -- David C. Rankin, J.D.,P.E.

Many of the referenced bug reports are paper cuts. None by itself breaks Trinity but all combined creates an uncomfortable feeling. :) If somebody explains how to resolve the broken sym link bug reports, which breaks the HTML help files for non English languages, I am willing to work on resolving them. Several of the other build related bugs are automake or cmake issues. I suspect most if not all can be resolved with nominal effort by experts. I'll work with anybody who tackles any of the listed bug reports. I will patch, build, and test as fast as my dual core will allow me. :) Darrell

Device Icons Bug Fixes
by Darrell Anderson 28 Mar '12

28 Mar '12

Recently two significant usability bugs were fixed with simple one-liners in the code: 372 Storage media applet doesn't show usb stick at session startup 385 Unmounted removable device icons do not appear on the desktop Both were resolved in GIT hash 43bb5b9. Along with the patch for bug report 392, "Device Icon Placement," sanity has been restored to device icons. Thank you everybody! Darrell

Trinity won't start
by Darrell Anderson 28 Mar '12

28 Mar '12

Recently David shared some issues with starting Trinity. In his case the probable cause seemed to be stale profile cache file or profile cache files using the old prefix names. Today I stumbled across a way to stall the session startup. I changed some settings in KControl. What caught my eye with this bug is the xsession log error, which David saw as well: ksmserver: '<wm>' missing. ksmserver: Use --help to get a list of available command line options. I traced the cause to these lines in my profile twinrc: [ThirdPartyWM] WMAdditionalArguments= WMExecutable=twin Those lines and group do not exist in a twinrc backup file and is the only difference between the files. This is not a hard freeze. Trinity exits gracefully back to the command line, which is how I start X/Trinity. The problem is with tdeinit_phase1. I commented out that command in starttde. I successfully substituted all of the following: kwrapper ksmserver --windowmanager twin --windowmanageraddargs "" kwrapper ksmserver --windowmanager twin kwrapper ksmserver Looking at the tdeinit_phase1 source code, I see that when WMExecutable is undefined/empty then tdeinit_phase1 defaults to "kwrapper ksmserver." As my previous twinrc contained no ThirdPartyWM group in twinrc, that is how tdeinit_phase1 always started. When I changed some settings in KControl to cause twinrc to update with including the ThirdPartyWM group, tdeinit_phase1 instead starts with "kwrapper ksmserver --windowmanager %1 --windowmanageraddargs %2." Changing the twinrc WMAdditionalArguments to WMAdditionalArguments=--lock allowed Trinity to start using tdeinit_phase1. I think the solution then is to add the following condition test to tdeinit_phase1: else if (wmArguments == "") { return_code = system((TQString("kwrapper ksmserver --windowmanager %1").arg(wmToLaunch)).ascii()); Comments?

ksquirrel build fail - undefined reference to `TQWidgetFactory::

Tim, All, There is a build failure in ksquirrel.

Does TDE XDG environment need to set LC_* variables?
by David C. Rankin 28 Mar '12

28 Mar '12

All, Upon k3b start, the only error received during startup check was: <quote> System locale charset is ANSI_X3.4-1968 Your system's locale charset (i.e. the charset used to encode filenames) is set to ANSI_X3.4-1968. It is highly unlikely that this has been done intentionally. Most likely the locale is not set at all. An invalid setting will result in problems when creating data projects. Solution: To properly set the locale charset make sure the LC_* environment variables are set. Normally the distribution setup tools take care of this. </quote> I know about a year ago, there was considerable discussion about where these variables should be set. Looking, it seems that some distros take care of this with XDG config which can be set separately between gnome XDG and kde XDG. Does TDE need to look at setting these? I don't know the answer. I do know SuSE sets them and Arch doesn't. So there is a variation between the way this is handled distro to distro. May not be a bad thing to do in the TDE config if these setting matter. -- David C. Rankin, J.D.,P.E.

Hell yah! Basket Notepads builds and works on TDE!
by David C. Rankin 28 Mar '12

28 Mar '12

All, For those not familiar with applications/basket (Basket Notepads), it is probably the finest 2nd brain invented for TDE. You can simply squirrel away all types of information and notes in a simple manner. (text, graphics, audio, colors, etc..) Think of it as an integrated sticky notes suite on steroids providing full search of all the information you have in it. I have built up hundreds of notes over the years and this is a must have app for me. Builds and works fine: http://www.3111skyline.com/dl/dt/trinity/ss/basket-1.0.3.jpg Tip: set the following settings for improved ease of use: (Basket tab) [x] insert note when clicking to the right of the insertion line. (General tab) Show main windows when mouse hovers over system try icon for 7 tenths second Crystal window decorations and basket notepads were the last 2 'must-haves' before I could ditch 3.5.12 and move to 3.5.14 as my daily driver :) -- David C. Rankin, J.D.,P.E.

crystal 1.0.5 builds 1.0.7 doesn't - how/what do I compare to figure out why?
by David C. Rankin 28 Mar '12

28 Mar '12

All, I have twin-style-crystal building on TDE. The version of crystal in GIT is 1.0.5. I want to get 1.0.7 building. I have both build directories and I will work though them to see if I can figure out why. What I would like to get is advise on what to start with to see if I can isolate the issue. Do I start with the 'configure' files and go from there, or is it better to diff the raw sources before trying to sort it out. Basically, the error with 1.0.7 is: g++ -DHAVE_CONFIG_H -I. -I.. -I/opt/trinity/include -I/opt/tqt3/include -I. -include tqt.h -I/usr/include/tqt -I/usr/include/tqt/Qt -DQT_THREAD_SUPPORT -D_REENTRANT -Wno-long-long -Wundef -ansi -D_XOPEN_SOURCE=500 -D_BSD_SOURCE -Wcast-align -Wchar-subscripts -Wall -W -Wpointer-arith -O2 -march=x86-64 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -Wformat-security -Wmissing-format-attribute -Wno-non-virtual-dtor -fno-exceptions -fno-check-new -fno-common -I/usr/include/tqt -MT embedtool.o -MD -MP -MF .deps/embedtool.Tpo -c -o embedtool.o embedtool.cpp In file included from embedtool.cpp:26:0: /usr/include/tqt/Qt/qimage.h:45:30: fatal error: QtGui/qtransform.h: No such file or directory compilation terminated. There is no QtGui/qtransform.h on my system even though it is included from tqt/Qt/qimage.h. Should I look for a missing package or option not-enabled on one of the packages that is already built? From searching, it looks like QtGui is a plugin to Qt (or in this case TQt). Is there such a thing in TDE? -- David C. Rankin, J.D.,P.E.
