I have a AMD OPTERON 64bit with SUSE LINUX SERVER 9.1. I tried to compile a software (tomoDD) in fortran with some subroutine also in C and I obtained this error message tomoDD.o(.text+0x65e): In function `MAIN__': : relocation truncated to fit: R_X86_64_PC32 contrl_ tomoDD.o(.text+0x5083): In function `MAIN__': : additional relocation overflows omitted from the output collect2: ld returned 1 exit status make: *** [tomoDD] Error 1 Any help will be greatfully received. thanks, Barbara
