tdelibs FTBFS: cmake 2.8.12: INTERFACE_LINK_LIBRARIES vs. LINK_INTERFACE_LIBRARIES
by Darrell Anderson 18 Dec '13

18 Dec '13

All, I gave a pass at compiling R14 on the newly released Slackware 14.1, which contains cmake 2.8.12. The arts package compiled with cmake warnings I never saw before and tdelibs FTBFS with the same warnings. The arts warnings: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in flow/gsl/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in flow/gsl/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: tdelibs: CMake Warning (dev) in tdecore/tdehw/CMakeLists.txt: CMake Warning (dev) in tdecore/tdehw/networkbackends/network- manager/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in tdecore/svgicons/CMakeLists.txt: CMake Warning (dev) in tdeio/tdeio/CMakeLists.txt: CMake Warning (dev) in libltdl/CMakeLists.txt: CMake Warning (dev) in tdehtml/java/CMakeLists.txt: Following the colon of each warning: Common to both arts and tdelibs: CMake Warning (dev) in libltdl/CMakeLists.txt: Policy CMP0022 is not set: INTERFACE_LINK_LIBRARIES defines the link interface. Run "cmake --help-policy CMP0022" for policy details. Use the cmake_policy command to set the policy and suppress this warning. Static library target "ltdlc-static" has a INTERFACE_LINK_LIBRARIES property. This should be preferred as the source of the link interface for this library. Ignoring the property and using the link implementation as the link interface instead. This warning is for project developers. Use -Wno-dev to suppress it. If I understand correctly from reading around the web, the cause is cmake 2.8.12 changed LINK_INTERFACE_LIBRARIES to INTERFACE_LINK_LIBRARIES. If that is correct, then seems TDEMacros.cmake:696 needs to be updated to handle both variables: target_link_libraries( ${_target} LINK_INTERFACE_LIBRARIES ${_shared_libs} ) I'm wild guessing something similar to this (I'm not a cmake guru): If (${CMAKE_MAJOR_VERSION}.${CMAKE_MINOR_VERSION}.${ CMAKE_PATCH_VERSION } GREATER 2.8.11) target_link_libraries( ${_target} INTERFACE_LINK_LIBRARIES ${_shared_libs} ) else() target_link_libraries( ${_target} LINK_INTERFACE_LIBRARIES ${_shared_libs} ) endif() I presume others will experience these same warnings and build failures when they update to cmake 2.8.12. Regardless, this requires a change to the common cmake sources, which need to be propogated through the source tree. Darrell

New motherboard advice
by Darrell Anderson 17 Dec '13

17 Dec '13

All, I'm considering an update to my office desktop computer I built 5 years ago. A new system with SATA III, USB 3.0, quad core, an SSD, etc, would seriously help with Trinity build times. I would like to keep the system as quiet as possible with no increase in the electric bill over my current dual core AMD system (about 65-80 watts). I'm grateful for suggestions and advice or sharing what you are using. Thanks :-) Darrell

As png files are already installed, then a short-term hack could ensure the svg files are not used. Long term, update the algorithm. >I don't think they're likely to change the icon set with every >update >to LO, so we can just check and update whenever *we* make a >new release. Only a few people are likely to notice or care >(unless >this also affects another DE's default icon set). The icon graphics likely do not change often. Just the file name of the icons, which use the version number. Darrell

With your understanding of svg file formats, do you feel comfortable contacting the LO team and ask them to consider releasing palatable icons? >The code to look at in TDE is >the stuff related to clipping, masking, and cloning in SVGs, but >it >may never be possible to make these files open acceptably fast on >a slow machine. They're just not made with that in mind. This likely is the best solution. Use more recent svg algorithms that do not suffer the same rendering problems. What algorithms are being used in other desktops? --- Take advantage of GPL code sharing practices. :-) >The only workaround that occurs to me at this time is overwriting >the files with something simpler after LO is installed, or else >deleting the SVGs outright and (hopefully) forcing the system to >fall back on the raster versions of the icons. A challenge to that idea is the LO devs name the icons with the LO release number in the file name. Maintaining our own png icon set would be overwhelming because with each LO release a new Trinity icon set is needed. Not to mention all past LO icons sets as well because they have included the release number in the file names for a long time now. >I can attempt to redraw the icons to produce substantially >identical >smaller SVGs to overwrite them with, but it would take a while, >so I'm not going to start until and unless we decide that this is >the way to go. Does not sound productive at the moment. :-) BTW, I used Trinity Gwenview to convert the 8 LO svg files to 256x256 png files. The png files all opened much faster in image viewers. Yet again, the challenge is the LO release number is part of the file name. Thus converting the images to png is doable as proof-of-concept, but impractical to implement. Darrell

Need an svg expert
by Darrell Anderson 15 Dec '13

15 Dec '13

All, In bug report 1591, we noticed Trinity struggles to open the svg files packaged with LibreOffice. Originally this was noticed when trying to open the Office submenu, but general perusing of the svg files reveals a slowdown. As the svg files are XML (text) files, would one of you graphics wizards look at the LO svg files for possible reasons why Trinity struggles with the files? Even on a dual core system the files need a few seconds to open whereas other svg files open immediately. The LO svg files get installed to /usr/share/icons/hicolor/scalable/apps. Thanks! :-) Darrell

Re: [trinity-devel] Help! fatal: destination path 'main/applications/ktorrent' already exists and is not an empty directory.
by Darrell Anderson 15 Dec '13

Looks like this tiny nightmare might be behind me. I don't know what happened, but some combination of git clone, git reset --hard HEAD, git clean -dxff, git checkout master, and manually copying missing admin and cmake .git folders seems to have gotten the switch_all_submodules_to_head_and_clean script to remain calm and quiet and stop terminating. No more fatal messages. I updated my wrapper script to tee the output of switch_all_submodules_to_head_and_clean script to a log. Took 3 hours to clone tde-i18n --- something not right about that. What a wasted day --- back to building packages and testing! Darrell

>It is strange to me, how could git folder just lose. >For tde-i18n would "lost" had to take some time. Strange to me too and I've had all day to think about a root cause. I know of only one thing I might have done to inadvertently delete the folders. Yet the conundrum of even that possibility is every single .git folder should have been deleted throughout the entire tree. That is not the case. Further, stand-alone files such as .gitmodules would have been deleted too, but those files are intact. Other than the .git folder the remainder of the tde-i18n module tree is intact. >Have you tried git fsck on the modules that are okay for now? Yes. I also tried git clean -f. Running 'git pull' results in an 'Already up to date' message and no errors. When I run the switch_all_submodules_to_head_and_clean script then the proverbial hell breaks loose because some of the modules are missing the respective .git folders. At this point I just want my local tree updated far more than solving the mystery of what happened. Further frustrating is the Trinity git server is really slow with respect to cloning. According to the progress bar, I'm downloading at about 80-90 KiB/s. At 1.1 GB and a 3 Mbps connection, the tde- i18n module should finish loading in about 50 minutes. I'm still waiting 90 minutes later and the tde-i18n clone is only 64% complete. At this rate, cloning the entire tree might take days. :-( Darrell
