[McIDAS #XYE-715198]: Mcidas Update

Hi Heather,

The operative lines from 'makelog' are the last:

gfortran -c -O -Wuninitialized -fno-automatic -fno-range-check 
-ffixed-line-length-none -fno-f2c -g -I. -I../netcdf/libsrc -I../hdf/hdf/src

compile convdlmf.f:             FAILED

Since I have not seen this before, I did a Google search using '__gmpn_sqr_n'
as the search key (with no single quotes).  The following two hits seem
to fit what you are seeing:

Reply to question in:

It looks like option 2 from the reply is the way to go:

1. Compile
   void __gmpn_sqr_n (unsigned long *rp, unsigned long *up, unsigned long n)
     {__gmpn_sqr (rp, up, n);}
   and link to your application.  How to link it, depends on your
   system.  N.B. This is a gros fix that bypasses the GMP typing system,
   but it should work on most systems.

2. Link to GMP 4.3.2 or perhaps an older release of GMP.


- my development environment is CentOS 6.3 x86_64

  As you probably know, CentOS is the "freeware" distribution of
  RedHat Enterprise, and v6.3 is the latest release.  Since I
  don't experience the problem you are seeing, and since my
  CentOS installation of GMP is newer than yours:

  CentOS 6.3 GMP:

  Your RedHat installation:

  I am assuming that newer versions of GMP provide the entry point
  that is missing from your installation, __gmpn_sqr_n.

- the other comment I have is that it is likely that your version
  of gfortran (and gcc?) are older than mine

  Here is what I ran that led me to this comment:

% rpm -qf /usr/libexec/gcc/x86_64-redhat-linux/4.4.4/f951

% file /usr/libexec/gcc/x86_64-redhat-linux/4.4.4/f951
/usr/libexec/gcc/x86_64-redhat-linux/4.4.4/f951: ELF 64-bit LSB executable, 
x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 
2.6.18, stripped


- was there an update to system utilities lately, and was there
  _not_ and update to the gcc and/or gfortran compilers?
