FWIW, it seems that there is an updated gif library
https://a3a2l.wordpress.com/2014/08/07/building-openscenegraph-on-linux/
OpenSceneGraph is using an older signature of the DGifCloseFile function
in libgif that got changed in version 5.1:
int DGifCloseFile(GifFileType *GifFile) // old
int DGifCloseFile(GifFileType *GifFile, int *ErrorCode) //new
As a workaround, and a clumsy one for that matter, I simply edited the
source code file
(../OpenSceneGraph-3.2.1/src/osgPlugins/gif/ReaderWriterGIF.cpp) and
changed line 564 to:
DGifCloseFile(giffile, 0); // I just assumed 0 is the exit code for a
successful close
OpenSceneGraph should now build successfully.
Note: In case you are using a x64 system, make sure to set
“/usr/local/lib64/” as your LD_LIBRARY_PATH environment variable.
