Re: grdmath problems

Hi,

Sounds like a flakey GMT in Ubuntu, see earlier messages
on this list.  On

   jjg@flounder ~ $ cat /etc/issue
   Linux Mint 16 Petra \n \l

with

   jjg@flounder ~ $ apt-cache policy gmt
   gmt:
     Installed: 4.5.7-2ubuntu1
     Candidate: 4.5.7-2ubuntu1
     Package pin: 4.5.7-2ubuntu1
     Version table:
        4.5.9-1 1001
         500 http://archive.ubuntu.com/ubuntu/ saucy/universe amd64
   Packages
    *** 4.5.7-2ubuntu1 1001
         500 http://archive.ubuntu.com/ubuntu/ raring/universe amd64
   Packages
         100 /var/lib/dpkg/status

This achieved with

   jjg@flounder ~ $ cat /etc/apt/preferences.d/pin-gmt4
   Package: gmt
   Pin: release n=raring*
   Pin-Priority: 1001

   Package: gmt-doc
   Pin: release v=13.04, l=Ubuntu
   Pin-Priority: 1001

   Package: libgmt4
   Pin: release v=13.04, l=Ubuntu
   Pin-Priority: 1001

   Package: *
   Pin: release v=13.04, l=Ubuntu
   Pin-Priority: -1

I get no error for

   jjg@flounder ~ $ GMT grdmath -R0/10/0/10 -I1 X = 1.grd
   jjg@flounder ~ $ GMT grdmath -R0/10/0/10 -I1 X = 2.grd
   jjg@flounder ~ $ GMT grdmath 1.grd DUP DUP 10 LE 0.65 MUL EXCH DUP

and

   jjg@flounder ~ $ ls -l *.grd
   -rw-r--r-- 1 jjg jjg 1240 Jan 22 19:41 1.grd
   -rw-r--r-- 1 jjg jjg 1240 Jan 22 19:41 2.grd
   -rw-r--r-- 1 jjg jjg 1508 Jan 22 19:42 3.grd

perhaps you could revert to 4.5.7 too

Cheers

Jim
