KFind straw poll
by Darrell Anderson 04 Apr '12

04 Apr '12

For me, a minor irritant about KFind is, in the Properties tab, when selecting "Find all files created or modified... during the previous..." defaults to 1 hour. Overwhelmingly I want to look for files changed within the last minute or two. I have to pause and manually change the default "hours" list item to "minutes." Wah, wah, wah! I want to change that default to minutes. This default makes sense to me anyway because that is the smallest period in the list. I already patched KFind for my systems. Should the patch be merged to GIT? Objections? Arguments? Tantrums? Declarations of War? Perhaps a better approach is to create a configuration option for the default then everybody could be happy. There is no configuration dialog I know about for KFind. The user's kfindrc is rather sparse and I don't know of any global kfind configuration file. Perhaps KFind should remember the last chosen options in the Properties tab and save them, much like is already done with the file path history. Darrell Darrell

Call for Help with Bug 949 ( digikam, koffice, gwenview ) libpng
by David C. Rankin 04 Apr '12

04 Apr '12

All Coders & Bug Fixers: The last two major packages that do not build on R14 with libpng15 are digikam and koffice. I have updated bug report 949 with the patches I have found for digikam and gwenview as well as the link to Darrell's patch he created for gwenview from the examples. The gwenview patch provided by Darrell allows gwenview to build fine, and it might serve as a model for the other two packages. I have tried to duplicate the patch for digikam and koffice, but the intricacies of that code is beyond my ability. It may be totally simple for someone experienced with this sort of thing to knock out in 15 minutes, but after picking though the headers and code for a couple of hours, it has become apparent that: (1) I do not understand how the calls are made by the code to png_struct and png_info enough to allow me to create the patch; AND (2) even if I were able to cobble something together that would allow digikam or koffice to build - I would not have enough confidence in the solution that would prevent someone from having to redo the fix to make sure it is right; AND (3) the time it would require me to gain the level of experience necessary to competently complete the patch would be much better spent contributing in areas where I can make a difference. Of the TDE packages, these are the last remaining major packages that need to be fixed for TDE to build on libpng15. Having those built would allow efforts to switch from developing build scripts to readying/fixing R14 for release. If one or two of the seasoned coders could look at bug report 949 and see if there is a fix in the patches I have provided links to, I would be grateful: http://bugs.pearsoncomputing.net/show_bug.cgi?id=949 -- David C. Rankin, J.D.,P.E.

I can't find any apps that depend upon mlt. Is mlt something we want to maintain? Darrell

No documentation in KHelpCenter... Build issue?
by David C. Rankin 04 Apr '12

04 Apr '12

All, The K Help Center has no documentation in it. It shows all the apps installed, but there is no documentation for any of it. Is that a build time issue (i.e. DOCPATH), or is there a problem with the generation of help files? Here is a screenshot of khelpcenter: http://www.3111skyline.com/dl/dt/trinity/ss/tde-no-documentation.jpg Is there an internal setting that will fix this? I just let the build put the documentation in its default location after setting prefix=/opt/trinity (TDEDIR). -- David C. Rankin, J.D.,P.E.

Can't run kdcop
by Darrell Anderson 03 Apr '12

03 Apr '12

Would somebody running GIT test whether you can run kdcop? Just pop up the mini cli (Run dialog, Alt-F2) and type kdcop. Thanks. Darrell

tde-config --version return of 'TDE: R14.0.0 [DEVELOPMENT]' causes build fail in kstreamripper
by David C. Rankin 03 Apr '12

03 Apr '12

All, I know little about scons or python, but working with kstreamripper it became apparent that the current 'tde-config --version' return was causing the build to fail due to the string not including a '3' which causes a chain reaction of failures: ==> Configuring - tde-kstreamripper... scons: Reading SConscript files ... scons: warning: The Options class is deprecated; use the Variables class instead. File "/build/src/kstreamripper/admin/generic.py", line 61, in generate ** set the installation prefix for the project : /opt/trinity ** Checking for tde-config : tde-config was found Checking for kde version : IndexError: list index out of range: File "/build/src/kstreamripper/SConstruct", line 70: env = Environment(TARGS=COMMAND_LINE_TARGETS, ARGS=ARGUMENTS, tools=['default', 'generic', 'kde'], toolpath=['./', './admin']) File "/usr/lib/python2.7/site-packages/SCons/Environment.py", line 999: apply_tools(self, tools, toolpath) File "/usr/lib/python2.7/site-packages/SCons/Environment.py", line 105: env.Tool(tool) File "/usr/lib/python2.7/site-packages/SCons/Environment.py", line 1783: tool(self) File "/usr/lib/python2.7/site-packages/SCons/Tool/__init__.py", line 180: self.generate(env, *args, **kw) File "/build/src/kstreamripper/kde.py", line 416: detect_kde(env) File "/build/src/kstreamripper/kde.py", line 58: kde_version = os.popen("tde-config --version|grep KDE").read().strip().split()[1] The error seems to boil down to the kstreamripper/kde.py check of the kde version: 17:44 nirvana:~/tde/tde/main/applications/kstreamripper> sed -n '58p' kde.py kde_version = os.popen("tde-config --version|grep KDE").read().strip().split()[1] 17:44 nirvana:~/tde/tde/main/applications/kstreamripper> sed -n '416p' kde.py detect_kde(env) A quick check of what TDE return with 'tde-config --version' confirms the issue: 17:39 valkyrie:~> tde-config --version Qt: 3.4.0 TDE: R14.0.0 [DEVELOPMENT] tde-config: 1.0 Basically, the python code is checking for the kde version as follows: print "Checking for kde version : ", kde_version = os.popen("tde-config --version|grep KDE").read().strip().split()[1] try: env['KDEm1']=int(kde_version[0]) except: pass try: env['KDEm2']=int(kde_version[2]) except: pass try: env['KDEm3']=int(kde_version[4]) except: pass if int(kde_version[0]) != 3 or int(kde_version[2]) < 2: print RED+kde_version print RED+"Your kde version can be too old"+NORMAL print RED+"Please make sure kde is at least 3.2"+NORMAL else: print GREEN+kde_version+NORMAL So it looks like when the check expects something for kde_version in the form '3.5.10', instead it gets 'R14.0.0'. How to solve this? There isn't really a file to patch since the tde-config --version info is returned dynamically. -- David C. Rankin, J.D.,P.E.

konqueror /servicemenu app - perhaps a good reference for other extensions
by David C. Rankin 02 Apr '12

02 Apr '12

All, Checking kde-apps for other kde3 apps that may work well with TDE, I ran across 'Root Actions Servicemenu' which adds a root actions menu to the konqueror context service menu. The applications added are largely duplicates of what are provided elsewhere, but some are not. Examples: Ownership to Root Ownership to Active User Ownership to ... See: http://www.3111skyline.com/dl/dt/trinity/ss/konqueror-root-actions.jpg The Ownership to ..., pop up a simple dialog with an edit line to set ownership to `user:group`. A great time-savings over: rt-click -> properties -> permissions -> Ownership -> listbox for :group (unless run as root) -> listbox open -> listbox select -> Moreover, often, you cannot set the user part of 'user:group' from the properties dialog unless you are superuser. This little python script did what kde3 is known for -- it took what would be a several button traverse across several dialogs and tabs and reduced it to a straight-forward: rt-click -> select -> enter data -> The value in this thing is that it can serve as a good model or 'go-by' to add whatever you want to a TDE service menu. Now I'm not keen on the servicemenu backend being python instead of c/c++, but it is worth a look at this thing if you want to add a service menu to an application. The kde-apps page for this is: http://kde-apps.org/content/show.php/Root+Actions+Servicemenu?content=48411 Very simple implementation. 1 python script in the path catches rt-clicks, displays the context menu and then executes the choice. The actual context menus are provided by 3 small .desktop files that are just copied to ~/.trinity/share/apps/konqueror/servicemenus (per user) or /opt/trinity/share/apps/konqueror/servicemenus for everyone. Roughly 60k for the entire bundle. Just food for thought. -- David C. Rankin, J.D.,P.E.

kaffeine & yakuake - both require '-fpermissive'
by David C. Rankin 02 Apr '12

02 Apr '12

Tim, Darrell, All, Just a note, both kaffeine & yakuake require --fpermissive to build, otherwise you get the char* to char** errors. I'll go see if I can find one of Darrell's patches that fix this and see if I can patch these two, but currently, I don't know what to look for... -- David C. Rankin, J.D.,P.E.
