Hi, Which libSBML version is required for rsbml? I couldn't find this information anywhere, and it doesn't work for libSBML 3.4.1 (and 2.4.0) on Fedora Core 10 Linux. Or is there another problem? Installation ended without error message, but then loading the library fails: > library('rsbml',lib.loc="/usr/lib64/R/library/") Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/usr/lib64/R/library/rsbml/libs/rsbml.so': /usr/lib64/R/library/rsbml/libs/rsbml.so: undefined symbol: SpeciesReferenceGlyph_getSpeciesReferenceId Error : .onLoad failed in 'loadNamespace' for 'rsbml' Error: package/namespace load failed for 'rsbml' Thanks, Rainer Machne
