kmenu item location in tdegraphics need new homes (More Applications: x, y, z)
by David C. Rankin 09 Mar '12

09 Mar '12

Tim, For R14, the kmenu entries for each of the apps should have a logical home in the kmenu tree. After loading tdegraphics I have 4 applications in the "More Applications" lost and found folder. See: http://www.3111skyline.com/dl/dt/trinity/ss/menu-MoreApplications-AppsNeedG… They include: KColorChoose KColorEdit KFax KIconEdit They are not the big apps like Gimp or the like, but there is no reason they should be stuffed in an innocuous named "More Applications" folder. I would propose putting them in the "Graphics/Graphics Utilities" folder. Simply renaming "More Applications" to "Graphics Utilities" would work. I would also move other apps from the current "Graphics Menu" into the Graphics Utilities Menu like: [Graphic Utilities] KColorChoose KColorEdit KFax KIconEdit MPovModeler KRuler KSnapshot I would also collect the 'Viewers' into a like menu of their own. Like "Graphics/Graphics Viewers" [Graphic Viewers] KDVI KFaxView FontView Kview Kuickshow That would leave the parent Graphics menu uncluttered and ready to receive the users main graphic apps. Food for thought for R14 -- David C. Rankin, J.D.,P.E.

kcontrol Security & Privacy/Password & User Account -- can't set photo for user
by David C. Rankin 09 Mar '12

09 Mar '12

Tim, In kcontrol /Security & Privacy/Password & User Account/ -- I can't set a photo for user. Under the Login Administration/User tab I selected the order for setting the icon to be Users,Admin which should allow the user to set his own face icon (that should allow the user to set his face here shouldn't it?) When you click on the square box to set the icon, you get this error: "Your administrator has disallowed changing your image." (bummer) Anyway, please confirm this behavior. If it is something controlled by kdmrc, then that will need to be adjusted to allow the user to set his own face by default. -- David C. Rankin, J.D.,P.E.

Creating flow diagrams from sources?
by Darrell Anderson 09 Mar '12

09 Mar '12

I have been looking around the web for an app to convert C++ source code to flow diagrams. I'm looking in the wrong places or nothing exists other than a few commercial apps. I was hoping the Umbrello tool could help, but that does not convert anything directly. Is there a way to do this? I want to map the entire docbook process. As I am still very much a novice C++ coder, I am in over my head trying to trace how everything connects. The process should be documented for the wiki. Ideas? Thanks. Darrell

tdegraphics libkscan ConfigureChecks.cmake patch
by David C. Rankin 08 Mar '12

08 Mar '12

Serghei, I have submitted a patch for the libkscan ConfigureChecks.cmake SANE_LIBRARIES concatenation bug. Please take a look at the patch provided for http://bugs.pearsoncomputing.net/show_bug.cgi?id=901 I think this will provide a more robust set of REGEX expressions for dealing with lib and ldflag strings and will work across all distros. The original REGEX expressions simply removed spaces which would result in flags being merged together causing the build to fail. This set of REGEX expressions eliminates all non-library information first leaving only a concise semi-colon separate list of library names. In short this is the patch: --- tdegraphics/libkscan/ConfigureChecks.cmake +++ tdegraphics/libkscan/ConfigureChecks.cmake 2012-03-08 15:51:30.452794166 -0600 @@ -39,8 +39,14 @@ string( REGEX REPLACE "(^| )-I" ";" SANE_INCLUDE_DIRS "${SANE_INCLUDE_DIRS}" ) endif( ) if( SANE_LIBRARIES ) - string( REGEX REPLACE "(^| )-l" ";" SANE_LIBRARIES "${SANE_LIBRARIES}" ) - string( REPLACE " " "" SANE_LIBRARIES "${SANE_LIBRARIES}" ) + ## remove all spaces and replace whitespace with ';' + string( REGEX REPLACE "[ ]+" ";" SANE_LIBRARIES "${SANE_LIBRARIES}" ) + ## remove all non-library information + string( REGEX REPLACE "[-][^l]([^ ;])+" "" SANE_LIBRARIES "${SANE_LIBRARIES}" ) + ## remove multiple ';' + string( REGEX REPLACE "[;]+" ";" SANE_LIBRARIES "${SANE_LIBRARIES}" ) + ## remove '-l' + string( REGEX REPLACE "-l" "" SANE_LIBRARIES "${SANE_LIBRARIES}" ) endif( ) if( NOT HAVE_SANE ) If it works for you, go ahead and commit it. -- David C.

Modify cmake process to update a source file before building
by Darrell Anderson 08 Mar '12

08 Mar '12

I am creating three new entities for the TDE help files. The entities will be stored in the sources tree in tdelibs/kdoctools/customization/entities/general.entities. These new entities will contain the document version, release date, and copyright years. The past practice with all KDE3 help files was to use hard-coded, static text strings. I want to change the fixed text to entities so they can be dynamic and always match the TDE release information. Conceptually, I tested these new entities by hard-coding them into general.entities and compiling a couple of modified docbook sources to use those entities. Works as planned. :) The next step is to modify the cmake build process to update the general.entities file when the tdelibs package is built. The macro or script, whichever is correct terminology for cmake, needs to work like this: * Extract the release version variable TDE_VERSION_STRING from tdelibs/tdecore/tdeversion.h. * Read the file date stamp of tdeversion.h (for GIT sources this will change regularly, for tarballs this will remain fixed) * Create a copyright year string in the form of "2010-$CURRENT_YEAR" * Update the text strings between the quotation marks in general.entities: <!ENTITY tde-release-version "R14.0.0 [DEVELOPMENT]"> <!ENTITY tde-release-date "March 8, 2012"> <!ENTITY tde-copyright-date "2010-2012"> * Continue with the build process. I think I can do something like that in a shell script but I am unfamiliar with how to do the same in cmake. I don't mind doing the grunt work and testing, but I appreciate guidance to do this. Thanks! Darrell

Re: [trinity-devel] QT API renaming! Why?!
by Timothy Pearson 08 Mar '12

08 Mar '12

<snip> >> Yes! I'll pick an obvious example, KHTML. I would like to replace the broken KHTML engine with Webkit using Qt4. Problem is, I can't link a Qt4 >> library into a TDE library or program due to symbol conflicts. Even if you trick the compiler and linker, the program will crash at runtime because the C++ runtime will not know which symbols (Qt3 or Qt4) to use when function names and static members have the same name. > But that is what the linker does. Isn't it? Looks at symbolic names and puts addresses instead. Therefore you shouldn't have name > conflicts at runtime. The crash you may encounter is because the linker chosen wrong symbols to link together in one algorithm. But this have obvious solution. Put the code you want to link with Qt4 in separate module and link only with Qt4. I still don't understand how is renaming better solves this. Could you please refer exact source file and function? Actually the linker creates a reference to a "mangled" symbol--see http://en.wikipedia.org/wiki/Name_mangling#Name_mangling_in_C.2B.2B Let's take a simple example, qWarning. This becomes _Z8qWarningPKcz in libqt-mt.so.3.3.8 (nm -D /usr/lib/libqt-mt.so | grep qWarning), and _Z8qWarningPKcz in /usr/lib/libQtCore.so (nm -D /usr/lib/libQtCore.so | grep qWarning). If my program references Z8qWarningPKcz, which library will the symbol resolver choose at runtime? They are not binary compatible with each other, and when the symbol resolver chooses the wrong one at runtime (which it will do quite often) the entire program will crash. <snip> > I suppose this could be done in more easy way without renaming. Not really, see above. :-) And if you want to work on a "pure" KDE 3.5.10 fork you have that right; just be aware that you will hit a dead end far before TDE will. ;-) Tim

tdegraphics build failure 2 : libkscan.so (linker error?)
by David C. Rankin 08 Mar '12

08 Mar '12

Darrell, all, Ran into another issue with tdegraphics that I can't solve by a dependency review: [ 31%] Building CXX object libkscan/CMakeFiles/kscan-shared.dir/imgscaninfo.cpp.o Linking CXX shared library libkscan.so /usr/bin/ld: cannot find -lsane-Wl,-O1,--sort-common,--as-needed,-z,relro,--hash-style=gnu-L/usr/lib collect2: ld returned 1 exit status make[2]: *** [libkscan/libkscan.so.1.0.0] Error 1 make[1]: *** [libkscan/CMakeFiles/kscan-shared.dir/all] Error 2 make: *** [all] Error 2 Is this a CMake issue? Linker error? What to look for? -- David C. Rankin, J.D.,P.E.

Need help troubleshooting
by Darrell Anderson 07 Mar '12

07 Mar '12

I'm working on bug report 892. Most of this work involves changing XDG categories (X-KDE-Whatever -> X-TDE-Whatever), which will help further distinguish Trinity from KDE3 and KDE4 and reduce potential conflicts. The work is going well but I have run into a challenge. When I rebuild tdelibs and tdebase to install desktop files to $PREFIX/share/applications/trinity rather than $PREFIX/share/applications/kde, a few things start breaking. Some keyboard shortcuts stop, but I can recover that by deleting the user's khotkeys config file and starting afresh. That problem might be related or not, or might just be cruft from its KDE3 days when I migrated profiles. The real problem is noticeable when I open Konqueror and select the Settings menu option. Most of the setting modules do not appear. The only modules that appear are the "native" ones: Behavior, Appearance, Previews & Meta-Data, and Performance. The associated desktop files built and installed to $PREFIX/share/applications/trinity just fine. I can solve the problem by creating a sym link from $PREFIX/share/applications/kde to $PREFIX/share/applications/trinity and restarting the session. I tried a new profile but that did not solve the problem either. Only the sym link, or building to $PREFIX/share/applications/kde, avoids the problem. I haven't tested with other packages because at this point I only need tdelibs and tdebase for testing. At this point I'm concluding that something in the code is hard-coded to look for $PREFIX/share/applications/kde. I can't find anything obvious or explicit. I've looked hard and am stumped. I would appreciate any help in this challenge. :) Thanks! Darrell
