Hi!

Seems ld can't find the ncar graphical library files.

/usr/bin/ld: não foi possível localizar -lncarg
/usr/bin/ld: não foi possível localizar -lncarg_gks
/usr/bin/ld: não foi possível localizar -lncarg_c
collect2: error: ld returned 1 exit status

Check if at /usr/local/ncl/lib you have the ncarg library files. (libncarg.a libncarg_c.a libncarg_gks.a libncarg_ras.a)
 
You seems to have the same problem that @stationUF, plus you are also having lots of "Rank missmatch errorrs",

The latter could be solved by adding this flag "-fallow-argument-mismatch" to the FFLAGS variable at the configure.oa file

Code: 
FC              =       gfortran
FFLAGS          =       -ffree-form -O2 -fallow-argument-mismatch -fconvert=big-endian -frecord-marker=4

hope it helps!
 
Thanks.
Now I've the same log.compile file than @stationUF

It try to find some files in /user/bin/ld but the folder Id doesn't exist.

Code: 
/usr/bin/ld: cannot find -lncarg: No such file or directory
/usr/bin/ld: cannot find -lncarg_gks: No such file or directory
/usr/bin/ld: cannot find -lncarg_c: No such file or directory
/usr/bin/ld: cannot find -lX11: No such file or directory
 
great,

If you only need to compile obsgrid.exe you won't need to install this ncarg library and so it wont be a problem.

What I would on your place is to check if netcdf library is correctly compiled and if it has support for netcdf-fortran

One way to check this is to run on the command-line:
Code: 
nc-config --has-f03

it should print "yes"

Also check if the paths to netcdf lib and include directory are correct.
Code: 
nc-config --fflags
and
Code: 
nc-config --flibs
 
The first output is yes.

The second: -I/home/jmcabrera/WRF/Build_WRF/LIBRARIES/netcdf/include

The third: -L/home/jmcabrera/WRF/Build_WRF/LIBRARIES/netcdf/lib -lnetcdff -L/home/jmcabrera/WRF/Build_WRF/LIBRARIES/netcdf/lib -lnetcdf -lnetcdf -lm
 
Perfect, so It should be working. Please share your comple.out and recheck if the exe has been created at the src dir
 
I think I've solved it, now obsgrid.exe is created.

I've follow this Unstable to install obsgrid on ubuntu 22.04 · Issue #10 · wrf-model/OBSGRID

I copied this code in the console and compile.

Code: 
sed -i 's/-C -P -traditional/-P -traditional/g' configure.oa
sed -i 's/-lnetcdf -lnetcdff/ -lnetcdff -lnetcdf/g' configure.oa
sed -i 's/-lncarg -lncarg_gks -lncarg_c -lX11 -lm -lcairo/-lncarg -lncarg_gks -lncarg_c -lX11 -lm -lcairo -lfontconfig -lpixman-1 -lfreetype -lhdf5 -lhdf5_hl /g' configure.oa
./compile FFLAGS=-fallow-argument-mismatch FCFLAGS=-fallow-argument-mismatch

Hi so mine was :
yes

What did you do? just put the this code on the terminal? or on the ./configure file?
