Konqueror - Filemanager Cleanup View->Background Image
by David C. Rankin 10 Mar '12

10 Mar '12

Tim, All, The current default for konqueror file manager "View->Background" is a KDE logo background. I always have to end up changing the setting to just "color" to enable the alternate-row highlight that makes looking at files in detail or tree view much easier. Two issues: (1) the default background images needs to be adjusted to TDE; and (2) why enable the background image by default anyway?? It kills alternate-row highlight. Just food for default thoughts :) -- David C. Rankin, J.D.,P.E.

GNU Image Finding Tool
by Darrell Anderson 09 Mar '12

09 Mar '12

The GNU Image Finding Tool (GIFT) package has not been updated in 7 years. I searched the web and seems that almost nobody packages that tool anymore. The only one I found was in the Debian repository split into several packages. The tdegraphics package installs an option to configure the GIFT in KControl, System Administration. The BUILD_KMRML option controls building that KControl option. Setting BUILD_KMRML=OFF avoids installing the KControl option but also disables mrml support. How much work is required to create a build option so the mrml support is built but not the KControl item? This would tie in somewhat with the KControl overhaul project. Can we use our own dog food and link KControl to a Trinity equivalent mrml app? Do we have any equivalent mrml image indexing tool? Darrell

CMake - how to add library to build?
by David C. Rankin 09 Mar '12

09 Mar '12

All, How do I add a library to a build in TDE? For some reason, the tdegraphics cmake setup does not include libXext. I have patched Makefile.am with -lXext and it is not seen by cmake or used for the build?? (Eg. I patched ksnapshot Makefile.am as follows): ksnapshot_LDADD = $(LIB_TDEPRINT) -lXext However, the ksnapshot link still fails: /usr/bin/ld: CMakeFiles/ksnapshot.dir/windowgrabber.cpp.o: undefined reference to symbol 'XShapeQueryExtension' /usr/bin/ld: note: 'XShapeQueryExtension' is defined in DSO /usr/lib/libXext.so.6 so try adding it to the linker command line /usr/lib/libXext.so.6: could not read symbols: Invalid operation collect2: ld returned 1 exit status I have looked at ConfigureChecks.cmake and all it includes is: check_include_file( X11/extensions/shape.h HAVE_X11_EXTENSIONS_SHAPE_H ) Can I tell cmake to include the library here? Or should the library inclusion go elsewhere? If so where? Is there a link to the cmake functions available in a TDE build? That would be very helpful to help packages not familiar with cmake held debug, etc.. I have found tde_add_library, but I don't know if that can be used to add an existing system library or if that is just to tell cmake to build and link the library?? Also, there are several forms: tde_add_library( kfaximage STATIC_PIC AUTOMOC tde_add_library( kfaximage SHARED AUTOMOC tde_add_library( ksvg SHARED If I can add libXext with tde_add_library would it be SHARED, STATIC_PIC and with or without AUTOMOC? I'm also not convinced that the problem isn't with cmake not concatenating or forming the link string properly after the problem encountered with libkscan. Below in the full error, there are man files just listed without any -l or -L preceding them. Is this correct? The full error I get with the tdegraphics/ksnapshot build is: [ 66%] Building CXX object ksnapshot/CMakeFiles/ksnapshot.dir/ksnapshotwidget.cpp.o cd /build/src/build/ksnapshot && /usr/bin/c++ -DHAVE_CONFIG_H -DKSNAPVERSION=\"0.7\" -march=i686 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -include tqt.h -I/build/src/build/ksnapshot -I/build/src/tdegraphics/ksnapshot -I/build/src/build -I/opt/trinity/include -I/opt/tqt3/include -I/opt/trinity/include/tqt -o CMakeFiles/ksnapshot.dir/ksnapshotwidget.cpp.o -c /build/src/build/ksnapshot/ksnapshotwidget.cpp Linking CXX executable ksnapshot cd /build/src/build/ksnapshot && /usr/bin/cmake -E cmake_link_script CMakeFiles/ksnapshot.dir/link.txt --verbose=1 /usr/bin/c++ -march=i686 -mtune=generic -O2 -pipe -fstack-protector --param=ssp-buffer-size=4 -D_FORTIFY_SOURCE=2 -DQT_NO_ASCII_CAST -DQT_CLEAN_NAMESPACE -DQT_NO_STL -DQT_NO_COMPAT -DQT_NO_TRANSLATION -DQT_THREAD_SUPPORT -D_REENTRANT -include tqt.h -Wl,-O1,--sort-common,--as-needed,-z,relro,--hash-style=gnu CMakeFiles/ksnapshot.dir/ksnapshotiface_skel.cpp.o CMakeFiles/ksnapshot.dir/main.cpp.o CMakeFiles/ksnapshot.dir/ksnapshot.cpp.o CMakeFiles/ksnapshot.dir/regiongrabber.cpp.o CMakeFiles/ksnapshot.dir/windowgrabber.cpp.o CMakeFiles/ksnapshot.dir/ksnapshotwidget.cpp.o -o ksnapshot -rdynamic -L/opt/trinity/lib -L/opt/tqt3/lib /opt/trinity/lib/libtdeprint.so.4.2.0 /opt/trinity/lib/libkio.so.4.2.0 /opt/trinity/lib/libtdeui.so.4.2.0 -lfreetype -lfontconfig /opt/trinity/lib/libtdesu.so.4.2.0 -lutil /opt/trinity/lib/libkwalletclient.so.1.0.1 /opt/trinity/lib/libtdecore.so.4.2.0 /opt/trinity/lib/libDCOP.so.4.2.0 /opt/trinity/lib/libtdefx.so.4.2.0 -ltqt -ltqt-mt -lXrender -lX11 -lz -lidn -lXcomposite -lICE -lSM -Wl,-rpath,/opt/trinity/lib:/opt/tqt3/lib: /usr/bin/ld: CMakeFiles/ksnapshot.dir/windowgrabber.cpp.o: undefined reference to symbol 'XShapeQueryExtension' /usr/bin/ld: note: 'XShapeQueryExtension' is defined in DSO /usr/lib/libXext.so.6 so try adding it to the linker command line /usr/lib/libXext.so.6: could not read symbols: Invalid operation collect2: ld returned 1 exit status make[2]: *** [ksnapshot/ksnapshot] Error 1 make[2]: Leaving directory `/build/src/build' make[1]: *** [ksnapshot/CMakeFiles/ksnapshot.dir/all] Error 2 make[1]: Leaving directory `/build/src/build' make: *** [all] Error 2 Thanks for any help you can offer. -- David C.

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
