COAWST fails to build WRF in Sandy Case

[HathewayWill]

@jcwarner-usgs I am trying to automate the installation of COAWST with all the libraries and files installed for users.

I have attached my script that I have created as well as a log file with the output from the build_coawst.sh.

There seems to be a module in WRF that isn't found. I have seen this error before in older versions of WRF that was fixed in 4.5.2. I'm not sure which version COAWST is coupled with.

Please help if you can.

Regards Error.zip

right near the top i see " gfortran: error: unrecognized command-line option ‘-assume’" there is a flag "-assume byterecl " this is for writing out binary files, like the matlab files for swan. suggest you comment that out. It would be in Compilers/Linux-gfortran.mk

that error cascades to other issues: make: *** [makefile:603: mct_params] Error 1 the mct_params is needed for the coupling.

work on fixing the bytrecl build issue first.

@jcwarner-usgs Thank you sir. I'll try that and let you know.

Also how do I enable the -j feature for building in parallel?

[HathewayWill]

Good morning sir,,

The removal of -assume byterecl allowed WRF to almost be built. Everything but wrf.exe was built and that caused swan to fail because it couldn't find wrf.exe I think.

Looking at the build log at line 5266 gives a ld status error 1 due to a undefined reference to main.

Not sure what could be causing this.

Could you take a look at the log?

...[ 97%] Linking Fortran executable ../bin/swan.exe ..... [ 97%] Built target swan.exe So it did build swan.exe. swan is all good. but actually i dont need swan.exe i dont need wrf.exe i dont need roms.exe All i need are the libs, and they get pulled together to make a coawstM.

you dont need to worry about .text+0x1b): undefined reference to `main' collect2: error: ld returned 1 exit status Command exited with non-zero status 1 0.16user 0.05system 0:00.21elapsed 100%CPU (0avgtext+0avgdata 126200maxresident)k 0inputs+110576outputs (0major+59869minor)pagefaults 0swaps make[2]: [Makefile:17: em_wrf] Error 1 (ignored)

that is ok.

your problem is:

ext_pnc_inquire_filename .... you are using parallel netcdf. for some reason we can not use paralle netcdf. there was another user who figured out a way to do that, but i have not looked at that yet.

so do this: export PNETCDF= make it blank, so wrf does not see anything. we dont want this: NetCDF built with PnetCDF: yes we want it to say no.

Thank you!

or maybe it is

export PNETCDFPATH = ' '

[jcwarner-usgs]

Also how do I enable the -j feature for building in parallel? when you type the build ./bulid_coawst.sh -j 6 or what ever number of procs you want to allocate to the build.

export PNETCDFPATH = ' '

ill just remove pnetcdf from the installlation. The only reason i had it was for wrf to run in parallel so that it runs faster. @jcwarner-usgs

@jcwarner-usgs

I believe everything is fixed now.

Here are the log files.

Is there a tutorial to run a test case to make sure it is coupled with the three models> (ROMS <-> WRF <-> SWAN) Sucess??.zip

[jcwarner-usgs]

there wasnt any files in that zip. There are lots of descriptions/test cases in the COAWST User Manual.doc. -j

[jcwarner-usgs]

did you get a coawstM ? ls -ltr is there a coawstM? if you got that file , you are good.

@jcwarner-usgs

Great got it!
