OpenSceneGraph 2.8.3 installation on Mac OS X 10.6 Snow Leopard - Building Failed

[huangpeng723@…]

I have tried to install openscenegraph but it fails to build. Does anyone have any idea how to get rid of the error?

10:~ peng$ sudo port install openscenegraph
--->  Computing dependencies for OpenSceneGraph

Error: Target org.macports.build returned: shell command failed

Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

In main.log the key info is some symbols not found (related to ffmpeg?)

Many thanks!

I have worked around this by disable ffmpeg:

cd /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_release_ports_graphics_OpenSceneGraph/work/OpenSceneGraph-2.8.3

edit CMakeLists.txt (comment following out)

...
#FIND_PACKAGE(FFmpeg)
...

Run make manually

sudo make

Finally

cd ~
sudo port install OpenSceneGraph

If you meet the same situation with me like follows:

10:~ peng$ sudo port install openscenegraph
--->  Computing dependencies for OpenSceneGraph
--->  Activating OpenSceneGraph @2.8.3_0
Error: Target org.macports.activate returned: Image error: /opt/local/lib/libOpenThreads.11.dylib already exists and does not belong to a registered port.  Unable to activate port OpenSceneGraph. Use 'port -f activate OpenSceneGraph' to force the activation.

Error: Status 1 encountered during processing.
To report a bug, see <http://guide.macports.org/#project.tickets>

delete conflicted files

sudo rm /opt/local/lib/libosg*

and run make again

sudo make

Done

10:~ peng$ sudo port install openscenegraph
--->  Computing dependencies for OpenSceneGraph
--->  Activating OpenSceneGraph @2.8.3_0
--->  Cleaning OpenSceneGraph

But I still have no idea how to fix ffmpeg, hopefully, I will not need that when I am using osg..

Does this still happen with 2.8.4?

[dbevans (David B. Evans)]

The ffmpeg plugin has been disabled in current OpenSceneGraph 3.0.1 allowing the port to build without ffmpeg support. See #38167 for the current failure mode.

The problem has been fixed upstream in OpenSceneGraph-devel 3.1.7. Use the +ffmpeg variant to enable this support.
