Re: [gembud] [EXTERNAL] Re: Problem compiling GEMPAK 7.20 on RHEL 9.10

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`

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.
Robert Mullenax
