Hi Joseph,

Apologies for the delay in getting back to you, I've been on PTO for the last 
few weeks.

A big caveat upfront, I do not have an Ubuntu system and so can not personally 
verify the instructions for installing on such a system, but I know many users 
have been able to build from source with some small changes to the normal set 
of instructions.

The set of instructions is at 
http://www.unidata.ucar.edu/software/gempak/doc/install.html

About halfway down the page is a short section for Ubuntu:

"
Ubuntu builds require the compiler flag -fno-stack-protector be added to COPT 
(C compiler options) and FOPT (fortran compiler options). Ubuntu-specific 
Makeinc files are provided in $NAWIPS/config/ that include this compiler flag:

$NAWIPS/config/Makeinc.linux_gfortran_ubuntu
$NAWIPS/config/Makeinc.linux64_gfortran_ubuntu
"

Basically, in $NAWIPS/config/ you will a number of "Makeinc*" files with 
compiler- and system-specific names, such as 

-rw-r--r--  1 gempak ustaff   58 Dec 11  2013 Makeinc.linux64
-rw-r--r--  1 gempak ustaff 1044 Dec 11  2013 Makeinc.linux64_g77
-rw-r--r--  1 gempak ustaff  988 Oct 19 18:36 Makeinc.linux64_gfortran
-rw-r--r--  1 gempak ustaff  997 Sep 30  2014 Makeinc.linux64_gfortran_fedora
-rw-r--r--  1 gempak ustaff  989 Sep 30  2014 Makeinc.linux64_gfortran_ubuntu
-rw-r--r--  1 gempak ustaff  999 Dec 11  2013 Makeinc.linux_g77
-rw-r--r--  1 gempak ustaff 1020 Sep 30  2014 Makeinc.linux_gfortran
-rw-r--r--  1 gempak ustaff  874 Sep 30  2014 Makeinc.linux_gfortran_fedora
-rw-r--r--  1 gempak ustaff 1028 Sep 30  2014 Makeinc.linux_gfortran_ubuntu

The default for 64-bit linux using gfortran, for example, is the file 
"Makeinc.linux64_gfortran".  Notice the additonal files called "_fedora" and 
"_ubuntu".  You will want to copy/move the file Makeinc.linux64_gfortran_ubuntu 
to Makeinc.linux64_gfortran before you run "make all" in $NAWIPS.  (Obviously 
for 32-bit systems do the above with the files "Makeinc.linux_" instead of 
"Makeinc.linux64_".

The differences between the two files can be seen with the command 

diff Makeinc.linux64_gfortran Makeinc.linux64_gfortran_ubuntu
11,12c11,12
< COPT = -DUNDERSCORE -D$(OPSYS) $(GEMINC) $(MOTIFINC) $(PYINC) $(WITHPY) 
-DG_64BIT -O2 -fPIC -g
< FOPT = -fno-second-underscore -fno-range-check -fd-lines-as-comments 
$(GEMINC) $(PYINC) -g #-O
---
> COPT = -fno-stack-protector -DUNDERSCORE -D$(OPSYS) $(GEMINC) $(MOTIFINC) 
> -DG_64BIT -g #-O
> FOPT = -fno-stack-protector -fno-second-underscore -fno-range-check 
> -fd-lines-as-comments $(GEMINC) -g #-O



With this _ubuntu file in place of the old "Makeinc.linux64_gfortran" file, you 
should be able to follow the rest of the instruction ("make all" followed by 
"make install",  or just "make everything").  

But again, I have no Ubuntu system myself to check this on, so if you encounter 
any build errors please let me know about them.
