Hello, I was trying compile a program on an Opteron system running SuSE 9.0 using pgf90 version 5.1-2 (linux86-64). The compilation of subprograms and modules goes smoothly but when trying to link the object files I get the following message: main.o(.debug_info+0x1a08)/usr/bin/ld: Dwarf Error: Could not find abbrev number 1193. : undefined reference to `..Dm_prec' main.o(.debug_info+0x1a19): undefined reference to `..Dm_charge' main.o(.debug_info+0x1a2a): undefined reference to `..Dm_pseudo' main.o(.debug_info+0x1a3c): undefined reference to `..Dm_lattice' main.o(.debug_info+0x1a4c): undefined reference to `..Dm_steep' ... Where the ..Dm_* files are modules. Does anybody has an idea of what's happening?
