[MOAB-dev] linking issues

Dear Vijay,
in attachment the config.log file.
I don’t think there’s a failure here. Indeed libMOAB.la is correct and MOAB tests compile and run.
 
The problem is that the path for libstdc++ is not included in the MOAB_LIBS_LINK in moab.make. Since I use moab.make to link MOAB to my application I need to add it manually

MOAB_LIBS_LINK = ${MOAB_LDFLAGS} -L${MOAB_LIBDIR} -lMOAB  -lm    -lhdf5 -lgpfs  -lz -ldl /cineca/prod/compilers/gnu/4.9.2/none/lib64/libstdc++.a

Is there an other (more correct) way to link MOAB?  

Thanks for help.
Lorenzo
