Issues when compiling DOUG

Architecture

32 vs 64 bit

Input format

• Integers in data files are 32 bits and default platform integer may be 64 bit. This breaks the reading of the input files.
  • It is the problem of file reading code, because it should be defined in input format specification and parsing of file must work on every platform.

Fortran

GFortran

record marker length

• add -frecord-marker=4 to FCFLAGS

G95

optional arguments

Must specify FCFLAGS=-fshort-circuit to configure, otherwise fails

• See http://www.cs.rpi.edu/~szymansk/OOF90/bugs.html (Danger with Optional Arguments)
