WC13/R4DVAR Compiling Problem

[ckers]

After compiling Build_roms.bash in the src/test/WC13/R4DVAR directory, I get the error below

src/test/WC13/R4DVAR/Build_roms/libUTIL.a(posterior_var.o): In function `__posterior_var_mod_MOD_posterior_var_tile':
posterior_var.f90:(.text+0xf036): undefined reference to `dpotrf_'
posterior_var.f90:(.text+0x12336): undefined reference to `dpotri_'
collect2: error: ld returned 1 exit status
=================================================================================
How can I solve this?

Hi, modellers

I am also facing a compiling error of WC13
I am trying to run the WC13 4D VAR test case..
Compiling I'm getting the following errors.

Please let me know, whats the problem?

I have compiled the ARPACK and created the libarpack.a libparpack.a and

if i commented the ARPACK LIBS and getting another following errors giving errors of -lnetcdf -lnetcdff libraries missing but installed the netcdf also..

Where are your libarpack.a and libparpack.a? Assuming your ARPACK source code is in the /root/ARPACK directory then both libarpack.a and libparpack.a should be in /root/ARPACK. The way you have things configured, you are telling the linker that libparpack.a is in the /root/ARPACK/PARPACK directory. Also, unless you are compiling and running ROMS as the root user (a really bad idea) it's likely that the you cannot access anything in the /root directory.

As for NetCDF, many things could be happening here and without a copy of your build_roms.{sh|bash} and my_build_paths.{sh|bash} it's hard to guess.

If WC13 is the first test case you are compiling as a ROMS user, I would suggest starting with the upwelling test case.

Thanks Robertson,

It resolved the problem.
I am trying to run the 4DVAR, so trying to run the WC13 and now ROMS I4DVAR is running successfully.
