Andrew Pinski <pinskia at gcc dot gnu.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|WAITING |RESOLVED Resolution|--- |INVALID --- Comment #8 from Andrew Pinski <pinskia at gcc dot gnu.org> --- Note the 4.3.0 is not referencing to 4.3.0 being installed. But rather you need to use libgcc_s.so from GCC 5.2 for libgfortran from GCC 5.2 to work. That is setup correctly LD_LIBRARY_PATH, etc.
