As of Ubuntu 8.10, g77 does not appear to be available in the Ubuntu
database. However, "gfortran" is available and can can be downloaded
and installed using "sudo apt-get install gfortran" from the Linux
command line. Versions of gfortran after version 4.1 are based on g95
but not a direct substitution for versions of g95 previously used with
NONMEM and PDx-Pop. I was able to find a workaround for my system that
hopefully will also work for others.
I downloaded gfortran and then "tricked" NONMEM and PDx-Pop into
thinking it was g95:
1. I created a symbolic link for gfortran to "g95":
sudo ln -s /usr/bin/gfortran /usr/bin/g95
2. I installed a fresh copy of NONMEM VI level 2.0 using the PDx-Pop 3.0
NMInstaller with the following settings:
- NONMEM VI Level 2.0
- /media/NONMEMVI2.0
- /home/bill/nm6g95 (not previously existing)
- GNU g95
- -O (not -O -fsloppy-char which would generate gfortran errors)
- New Install
- Intel
There were NUMEROUS Hollerith Warnings in the Installation Output window
and it seemed to take longer than usual but it eventually finished with
"End of Installation" in the window. I exited the NMInstaller and
returned to PDx-Pop.
3. I edited line 505 of the file /home/bill/pdxpop3/Go5pkg.pm by
removing "-fsloppy-char" from the line.
"nonmem -O -fsloppy-char" --> "nonmem -O "
4. In PDx-Pop, I used Tools > Edit Configuration, to change NonMemDir,
FortranFlag and Foptions to /home/bill/nm6g95, G95 and -O, respectively,
and saved the configuration and closed the configuration editor.
PDx-Pop then ran as expected with G95 (actually gfortran) including
NONMEM output in the Output Window.
Note: No changes to the source code other than those automatcally made
by the PDx-Pop NONMEM Installer are necessary. Previous posts regarding
the BLKDAT.f file recommended changing the second and third instances of
/dev/null to /dev/tty and JUNK for NONMEM. The values used by PDx-Pop
for NONMEM are /dev/stdout and /dev/null, respectively.
For those running and/or installing NONMEM from the Linux command prompt
on Ubuntu, the SETUP c-shell script included on the NONMEM distribution
CD-ROM can be used to install NONMEM after downloading gfortran. The
c-shell is not the default shell and may not have been installed by
Ubuntu. You can download and install the c-shell using "sudo apt-get
install csh". You don't have to use the c-shell to run SETUP or nmfe6,
but, they must be installed on your system for these scripts to work.
1. I created a symbolic link for gfortran to "g95":
sudo ln -s /usr/bin/gfortran /usr/bin/g95
2. Run setup from the /media/NONMEMVI2.0 directory with appropriate
arguments:
./SETUP /media/NONMEMVI2.0/ /home/bill/nm62gf g95 -O /usr/bin/ar Intel n
3. At Step. 5 of SETUP when it stops to allow modification of NONMEM
source files, I edited line 28 of BLKDAT.f as follows:
1/'/dev/null','/dev/stdout','PRDERR','INTER','/dev/null'/
and then allowed the SETUP script to finish.
4. I tested the installation by changing to the /home/bill/nm62gf
directory and running CONTROL5:

Note the alignment warning (that can be ignored) and lack of NONMEM
