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.
