Re: [osg-users] [build] SDL no longer builds
Hi Francois,
I've just cleaned up the present3D optional build with SDL so it's
similar to that of osgviewerSDL, as well as some other clean ups. You
may need to remove you OpenSceneGraph/CMakeCache.txt and then re-run
./configure. By default the SDL support should be off but you'll be
able to enable it via ccmake ., and then enabling the
BUILD_PRESENT3D_WITH_SDL option.
BTW, I live and work in Callander down in the Trossachs, and am
working on a project with Aberdeen University on medical visualization
and teaching. So once every few months I get to stick my head up
around your neck of the woods.
Robert.

Re: [osg-users] [build] SDL no longer builds
Hi François, Good to see you've got your issues sorted. That's the power of a large community, more testing and more eyeballs means fewer bugs! Aberdeen, nae as bonny as Montreal I've had a laugh at all your signatures, you have a vivid imagination to come up with a different one each time :-) Do they loop around or do you just type in a new one each time?

Re: [osg-users] [build] SDL no longer builds
Hi Francois, I'm working on Kubuntu 9.04 and haven't seen any of these problems, but I'm using the standard CMake built Makefiles for build the OSG. Could you build Makefiles and see if the build works fine as it code be that CMake CodeBlocks support isn't 100%. Robert.

I have added the following 2 lines
SET(TARGET_EXTERNAL_LIBRARIES ${SDL_LIBRARY} )
INCLUDE_DIRECTORIES(${SDL_INCLUDE_DIR} )
just before
IF (SDL_FOUND)
and present3D now compiles and links
As my understanding of cmake is very patchy, I have no idea if this is a valid
patch that would work if SDL is not found by cmake or if the user did not
select SDL
works for me and is cleaner than manually editing the generated Makefiles
though ;-)

Re: [osg-users] [build] SDL no longer builds
Hello François,
Nice to see you on this mailing list :-)
I can't comment for SDL or WxWidgets, it's been ages since I've compiled
those at all.
But in general, manually tweaking the makefiles won't help long term,
you need to find out why CMake is generating the makefiles that don't
work and fix it at the source.
ffmpeg also requires a lot of manual modifications (here again #include swscale.h
is used instead of the correct #include libswscale/swscale.h). Manual
specification of all include folders in cmake-gui allows build (strange that cmake finds
ffmpeg but does not configure the CMakeFiles correctly for actual valid OSG compile).
The Makefile should add the correct library directories, because the
CMakeLists.txt for the ffmpeg plugin has these lines:
INCLUDE_DIRECTORIES(
${FFMPEG_LIBAVFORMAT_INCLUDE_DIRS}
${FFMPEG_LIBAVFORMAT_INCLUDE_DIRS}/libavformat
${FFMPEG_LIBAVDEVICE_INCLUDE_DIRS}
${FFMPEG_LIBAVDEVICE_INCLUDE_DIRS}/libavdevice
${FFMPEG_LIBAVCODEC_INCLUDE_DIRS}
${FFMPEG_LIBAVCODEC_INCLUDE_DIRS}/libavcodec
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}
${FFMPEG_LIBAVUTIL_INCLUDE_DIRS}/libavcodec
)
IF(FFMPEG_LIBSWSCALE_FOUND)
INCLUDE_DIRECTORIES(
${FFMPEG_LIBSWSCALE_INCLUDE_DIRS}
${FFMPEG_LIBSWSCALE_INCLUDE_DIRS}/libswscale )
ADD_DEFINITIONS(-DUSE_SWSCALE)
SET(TARGET_EXTERNAL_LIBRARIES ${FFMPEG_LIBRARIES}
${FFMPEG_LIBSWSCALE_LIBRARIES})
ENDIF()
So you see, #include swscale.h should work because
ffmpeg_dir/include/libswscale should be in your include search path.
As to why it doesn't work, I guess you'll have to investigate.
Sorry I can't help more, but hopefully I pointed you in the right
direction for further investigation...
J-S

Re: [osg-users] [build] SDL no longer builds
I can't replicate the SDL problems (and haven't tried the other ones). After enabling BUILD_OSG_EXAMPLES in ccmake I have the following values for the SDL visible under the advanced section of the cache: SDLMAIN_LIBRARY */usr/lib/libSDLmain.a SDL_INCLUDE_DIR */usr/include/SDL SDL_LIBRARY */usr/lib/libSDLmain.a;/usr/lib/libSDL.so;-lpthread osgviewerSDL.o compiles just fine.
