Hello all,
I have the same problem with OSG 2.2.0 or 2.3.6, collada plugin and collada 1.4
dom 1.3.
I've search on collada forum and found 2 things :
1- in the collada_dom source, dae directory, edit the Makefile_PC to add
daeRawResolver.cpp and compile as usual.
COLLADA_DOM/src/dae/Makefile_PC:
[...]
# files
SRC := dae.cpp \
daeArray.cpp \
daeAtomicType.cpp \
daeDocument.cpp \
daeDom.cpp \
daeElement.cpp \
daeError.cpp \
daeErrorHandler.cpp \
daeIDRef.cpp \
daeMemorySystem.cpp \
daeMetaAny.cpp \
daeMetaAttribute.cpp \
daeMetaChoice.cpp \
daeMetaCMPolicy.cpp \
daeMetaElement.cpp \
daeMetaElementAttribute.cpp \
daeMetaGroup.cpp \
daeMetaSequence.cpp \
======> file to add daeRawResolver.cpp \
daeSIDResolver.cpp \
daeStringRef.cpp \
daeStringTable.cpp \
daeURI.cpp \
domAny.cpp
[...]
2- in OpenSceneGraph-build-tree/src/osgPlugins/dae/CMakeFiles/osgdb_dae.dir
directory you have a file named
"link.txt". This file contains the link command to produce osgdb_dae.so from
all object file. For some reasons all the
collada the collada libraries are not here. So I modified this file and run it
to produce a new osgdb_dae.so which works
fine (no more undefined symbol).
old build-U7.04_32/src/osgPlugins/dae/CMakeFiles/osgdb_dae.dir/link.txt:
/usr/bin/c++ -fPIC -O3 -DNDEBUG -shared -Wl,-soname,osgdb_dae.so -o

-lcollada_dom -Wl,-Bdynamic -losg -lm
-lOpenThreads -lpthread -lGLU -lGL -lSM -lICE -lX11 -lXext -Wl,-rpath,SOMEPATH
new command to build osgdb_dae.so:
/usr/bin/c++ -fPIC -O3 -DNDEBUG -shared -Wl,-soname,osgdb_dae.so -o
osgdb_dae.so *.o -LSOMEPATH -lOpenThreads -losg
-losgDB -losgUtil -lcollada_dae -lcollada_dom -lcollada_dae
-lcollada_STLDatabase -lcollada_stdErrPlugin
-lcollada_LIBXMLPlugin -lxml2 -Wl,-Bstatic -lcollada_dom -Wl,-Bdynamic -losg
-lm -lOpenThreads -lpthread -lGLU -lGL
-lSM -lICE -lX11 -lXext -Wl,-rpath,SOMEPATH
note that -lcollada_dae is include twice as specified in collada forum.
I'm sure it is possible to modify CMAKE to do the right things, but I'm not
CMAKE fluent and it is scheduled that all
this will die with collada DOM 2.0 and OSG 2.4.
Hope this will work for you,
Johan.
