Re: Failed to checkin an icon file (.ico) in RCS

[Aaron S. Hawley]

Here's a possible answer to your question available on the Web. The URL
is below:

  I'm hitting the binary save problem described [...]

    $ diffutils-2.7/diff /bin/ls /bin/cat ; echo $?
    Binary files /bin/ls and /bin/cat differ
    1
    $ diffutils-2.8.1/src/diff /bin/ls /bin/cat ; echo $?
    Binary files /bin/ls and /bin/cat differ
    2

  [...]

  Answer

  Ok, I figured out the problem. If you compile RCS (using the default
  Solaris diff), and then recompile to use the GNU diff, without running
  "configure" again, the compile options from configure are set based on
  Solaris diff, not GNU diff. In particular, the DIFFFLAGS are -n, not
  -an; the -a "treat all files as text" flag is required for RCS to work with
  binary files. (Maybe testenv could be enhanced to try doing ci on two
  different binary files to make sure the rcs/diff code works correctly?)
