[Met_help] MET compilation error

[John Halley Gotway]

Holly,

I believe this error has to do with how you compiled BUFRLIB.  Please take
a look at the sample commands for compiling BUFRLIB on this page:
http://www.dtcenter.org/met/users/support/online_tutorial/METv2.0/compilation/req_libs.php

Try compiling BUFRLIB with the following commands:
      gcc -c -DUNDERSCORE *.c
      gfortran -c -DUNDERSCORE -fno-second-underscore *.f *.F
      ar crv libbufr.a *.o

I think that "-fno-second-underscore" will fix the error you're seeing.

Hope that does the trick.

Thanks,
John Halley Gotway
