[MITgcm-devel] Symbolic linked _mpi

[Ed Hill]

Hi Alistair,

OK, you got me, I certainly forgot to check that $MPI was enabled.  My
mistake.
 
But you missed one of the finer points of my earlier emails.  The syntax
to use is:

  test "x$foo" = "x$bar"

not

  test "x$foo" == "x$bar"

You'll notice that the latter is not mentioned if you do a "man test"
and the "==" is actually non-portable.  It works on the Linux boxes and
fails on most of the commercial Unixes.  And if you don't believe me,
just try:

   test a == a && echo hi

on one of the Linux machines and then try it using the Bourne shell on
one of the IBM SP3/4's where you'll get:

  $ test a == a && echo hi
  sh: ==: 0403-012 A test command parameter is not valid.

Ed
