Hello, I just had quite a hard time building synfigstudio on my (Gentoo) Linux system from the current git master (612c6a). Just wanted to give you some feedback wrt the autotools and new CMake build tooling. CMake =====
My first attempt was to build with CMake (as I know CMake a little better than autotools). 1) I was expecting a to find a CMakeLists.txt in the "top level" directory of synfig-core, but found it only in the synfig-core/src directory. This was quite confusing, think it should have a synfig-core/CMakeLists.txt file as the ETL/CMakeLists.txt and the synfig-studio/CMakeLists.txt file. After I found the synfig-core/src/CMakeLists.txt file, build of synfig-core worked fine. 2) Building synfigstudio using CMake worked fine, but `make install` failed due to noumerous missing .png files. There were .sif files for all missing .png files, but no .png files were created during the build process. As far as I understood this is a known todo issue of the CMake build (README.md CMake status says: "not all icons are built"). But to me it seems that missing icons make the CMake build approach inappropriate for from-the-scratch builds :( Or how would I generate all required .png files when using the CMake build system? 3) synfigstudio `make install` required splash_sceen-*.png images for various versions of synfig (splash_screen-0.63.00.png, synfig-studio.cmake/images/splash_screen-1.0.1.png, ...) though I was building version 1.0.2. This seems to me a glitch in the CMake build configuration. Autotools ========= Due to the missing .png files for synfigstudio's `make install` with the cmake approach I switched back to the autotools build system. 4) Even though I built and installed ETL and synfig-core successfully using CMake, synfigstudio's autotools ./configure script would not find these libraries. I found that the script *would* find these libraries after building and installing them again using autotools. I have not investigated this issue too much, but I would guess that the CMake build tooling misses the step in the installation process (when running `make install`) that enables pkg-config to find these libraries being installed. Building and installing ETL, synfig-core and synfig-studio in that order using autotools for all of these (as described here http://wiki.synfig.org/Dev:Build_Instructions#System_wide_build_Instructions) worked fine. But: 5) When building synfig-studio, most of the .png files generated from the .sif files in synfig-studio/images where empty, i.e. contained 128x128 apparently transparent pixels. Only some files had valid content (e.g. tool_fill_icon.png, tool_scale_icon.png). Thus, when starting synfigstudio, most of the buttons had empty icons or where even invisible (which made synfigstudio nearly unusable). My quick and dirty workaround for this was to download a binary package of synfig and copy all .png files found in share/pixmaps/synfigstudio to /usr/local/share/pixmaps/synfigstudio. Works for me for most (but not all) .png images -- but I guess this should be fixed somewhere in the .sif files or in the build system? General ======= 6) I had to set CXXFALGS="-std=C++11" to be able to build synfig-core and synfig-studio. (I am using GCC 4.9.3.) Using CMake, I did this with `ccmake .` -> toggle to advanced -> edit CXXFLAGS; using autotools, I passed it to configure: `./configure CXXFALGS="-std=C++11"`. I am done now with building synfig on my machine (for this time), but I just wanted to give you some feedback about the things I noticed when building it and I wanted to share my experiences and the workarounds I found with the mailing list. Would be glad to provide more information on any of the issues I mentioned in case you need more info on any of these. Thanks for your dedication to synfig! Great open-source tool! :) Best regards Thilo ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, SlashDot.org! http://sdm.link/slashdot _______________________________________________ Synfig-devl mailing list Synfig-devl@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/synfig-devl
