I faced some problems while building MLT framework on windows using MinGw. I tried to follow instructions on http://www.mltframework.org/bin/view/MLT/WindowsBuild . I completed every step until step called "Build". This is what 7th step of "Build" chapter yields: $ ./configure --prefix=$HOME/build --enable-gpl --disable-decklink Configuring framework: Configuring modules: Configuring modules/avformat: - libavformat not found: disabling Configuring modules/core: Configuring modules/dv: - libdv not found: disabling Configuring modules/feeds: Configuring modules/frei0r: Package frei0r was not found in the pkg-config search path. Perhaps you should add the directory containing `frei0r.pc' to the PKG_CONFIG_PATH environment variable No package 'frei0r' found Configuring modules/gtk2: - GTK2 components not found: disabling Configuring modules/jackrack: - jackrack not found: disabling - xml2 not found: disabling jackrack - ladspa not found; disabling Configuring modules/kdenlive: Configuring modules/kino: - does not build on OS X or Windows: disabling Configuring modules/linsys: - does not build on OS X or Windows: disabling Configuring modules/lumas: Configuring modules/motion_est: Configuring modules/normalize: Configuring modules/oldfilm: Configuring modules/opengl: - movit not found: disabling Configuring modules/plus: Configuring modules/plusgpl: Configuring modules/qt: - Qt not found - disabling ./configure: line 150: kde4-config: command not found Configuring modules/resample: - libsamplerate not found: disabling Configuring modules/rtaudio: Configuring modules/sdl: Configuring modules/sox: - sox not found: disabling Configuring modules/swfdec: - swfdec not found: disabling Configuring modules/vid.stab: - vid.stab not found: disabling Configuring modules/videostab: Configuring modules/vmfx: Configuring modules/vorbis: - ogg vorbis not found: disabling Configuring modules/xine: Configuring modules/xml: - xml2 not found: disabling xml module Configuring mlt++: Configuring swig: GPLv2 license used; GPLv3 components disabled Looks like even on configuration phase some libraries are missing, I'm not sure whether these missing libs are mission-critical though... When trying to take 8th "Build" step called "make all install" build fails and MinGw spits out error: C:\MinGW\msys\1.0\home\Benas\src\mlt\src\framework/mlt_repository.c:101: undefined reference to `dlsym' C:\MinGW\msys\1.0\home\Benas\src\mlt\src\framework/mlt_repository.c:109: undefined reference to `dlclose' C:\MinGW\msys\1.0\home\Benas\src\mlt\src\framework/mlt_repository.c:97: undefined reference to `dlopen' C:\MinGW\msys\1.0\home\Benas\src\mlt\src\framework/mlt_repository.c:118: undefined reference to `dlerror' C:\MinGW\msys\1.0\home\Benas\src\mlt\src\framework/mlt_repository.c:113: undefined reference to `dlclose' collect2.exe: error: ld returned 1 exit status make[1]: *** [libmlt-6.dll] Error 1 make[1]: Leaving directory `/home/Benas/src/mlt/src/framework' make: *** [all] Error 1 This must be because compiler can't find dlfcn.dll. I have "dlfcn-win32" step from tutorial completed and that library can be found both on C:\MinGW\bin and C:\MinGW\msys\1.0\home\Benas\build . I'm wondering why compiler can't see it and is there any way how can I make it work? The mlt sources are located in C:\MinGW\msys\1.0\home\Benas\src\mlt .
