Hi all, I have having difficulty compiling feff 8.4. I am using gcc version 4.1.1 20070105 (Red Hat 4.1.1-52) on Scientific Linux 5.0. It compiles but gives many warnings like: Warning: Obsolete: arithmetic IF statement at (1) In file FEFF810.F:4208 if (i-1) 85,85,83 The compile finished however and I tried to run it. The input file was a BN example file that came with Feff 8.1. It runs for a little while and stops with: Done with module 1: potentials. Calculating LDOS ... At line 47994 of file feff84.f Fortran runtime error: Bad value during integer read I compiled using: gfortran -O2 -o feff84 feff84.f Has anyone seen this sort of thing? Or compiled Feff 8.4 with gfortran? I did the same with feff 8.1 and it compiled and ran correctly. Cheers, Adam -- ---------------------------------------------------------- Dr. M.
