Amen to that, Robert!! Daryl, your ongoing work to ensure GEMPAK never "gp"ends
is hugely appreciated!
Now, given your entreaty to invite more community participation via GitHub, who
wants to be the first to add "GEMPAK needs an Apple Silicon build" as an Issue?
(this is not a rhetorical question, but maybe it is).
Speaking of issues, I'm sure myself and the rest of the community would
strongly take issue with your self-descripton of you being "one of the
least-sharp tools in the shed"!
Thanks again!!
Best regards,
Kevin

Hi Robert,
To followup on this, I am thankful you pointed out this problem and it provoked
me to (hopefully) fix the Github repository CI so that these types of failures
don't happen again. For the rest of the interested GEMPAK Users here a bit of
commentary on this situation.
- I have never liked the idea of GEMPAK's Makefile system silently proceeding
after encountering errors. I can see the point that GEMPAK is so massive that
having a few packages fail may not mean much to most users. The year is 2026
though and yours truly has taken steps to stop this madness going forward. The
github main branch has many more instances now were compilation failures will
stop the full build.
- While NCEP continues to make NAWIPS releases, the code changes are rather
small and I am not as worried anymore about merging these code changes back
into GEMPAK, so the idea of Community GEMPAK diverging more from upstream
NAWIPS is no longer a non-starter to me.
- I was lazily not generating binary builds of GEMPAK releases, but will try to
start doing that going forward. I have a ways to go on this yet, but am hoping
to make a 7.20.0.1 release with binary artifacts available , famous last words.
- I have also started to consider replacing various extlibs content with
user/system provided libraries. This may not be practical for ancient library
versions like netcdf and hdf5, but I had some luck with png, libxslt, and
libxml2. None of this has happened on github yet, but if others listening here
are interested....
I would encourage folks to collaborate on GEMPAK on github. I'm one of the
least sharp tools in the toolbox, but enjoy tinkering with GEMPAK and would
like to see its legacy continue!
daryl

Hi Daryl,
dfmfrq.o is missing from gempak/source/diaglib/df/Makefile and pdmfrq.o is
missing from gempak/source/diaglib/pd/Makefile
I added those to the respective Makefile and recompiled and it seems to have
all worked.
Thanks for pointing me in right direction!

Hi Robert,
My initial thought is that dfmfrq is missing from
gempak/source/diaglib/df/Makefile COBJS
Will have to research this some more!

Hi Daryl,
No this is a new install of RHEL 9 and GEMPAK has not been built before on this
machine. After the first failed attempt I just wiped the GEMPAK directory and
unzipped main.zip again.
No, the only errors are the undefined reference below referring to df_mrfq.
Dfmfrq.c does not show in make.out.
Thanks,
Robert

Hi Robert,
Is the file `/home/gempak/GEMPAK/os/linux64/lib/gemlib.a` old from a previous
build? Otherwise, do you see an earlier error around compilation of `dfmfrq.c`

Subject: [gembud] Problem compiling GEMPAK 7.20 on RHEL 9.10
Good afternoon,
I am having an issue compiling GEMPAK 7.20 on RHEL 9.10. The build completed
and I did an install, but when I open NTL I found that NMAP2 and NSHARP did not
build, along with other programs. Here is the error I am seeing. This is seen
several times in the make.out Anyone have any ideas?
/usr/bin/ld: /home/gempak/GEMPAK/os/linux64/lib/gemlib.a(dgdriv.o): in function
`dg_driv':
/home/gempak/GEMPAK/gempak/source/diaglib/dg/dgdriv.c:367: undefined reference
to `df_mfrq'
collect2: error: ld returned 1 exit status
make[5]: *** [Makefile:185: nmap2] Error 1
Thanks very much.
