error ww3_grib.o not found when i compile ww3-6.07 model with ncep2

[aminekhedim]

I want to generate output format grib2.I change NOGRB to NCEP2 in switch and compile the libraries zlib1.2.6 g2lib-3.1.0 jasper-1.900.1 l ibpng-1.2.34 and w3lib-2.0.6 and add the path libs=" -L/home/user/libs/lib -L/home/user/g2lib.3.1.0 -lg2 -lw3 -ljasper -lpng " in the link but when i try to compile the model which NCEP2 he have error ww3_grib.o not found, i don t know how fix this error

It's admittedly been a while since I've run the 6.07 release, but usually it's because you don't have environment variables set right. For example if I was using the link file here: https://github.com/NOAA-EMC/WW3/blob/main/model/bin/link.wcoss_phase2#L143-L149

After loading my modules I would do: echo ${G2_LIB4} ${W3NCO_LIB4} ${BACIO_LIB4} ${JASPER_LIB} ${PNG_LIB} ${Z_LIB}"

and make sure each of these variables are defined.

I have all the libraries in a single directory called libs. Do I just declarein link libs=‘$libs’ or do I declare all the paths with the *.a in path ? can i have a exemple of declaration

[aminekhedim]

i tried use load each libraries using libs="${G2_LIB4} ${W3NCO_LIB4} ${BACIO_LIB4} ${JASPER_LIB} ${PNG_LIB} ${Z_LIB}" in file of link but doesn t wok i install all libraries in ~/NCEPLIBS/libs amine@khedim-ThinkStation-P500:~/NCEPLIBS/lib$ lls total 23556 -rw-r--r-- 1 amine amine 150446 juin 5 14:30 libz.a -rwxr-xr-x 1 amine amine 126232 juin 5 14:30 libz.so.1.2.13 lrwxrwxrwx 1 amine amine 14 juin 5 14:30 libz.so.1 -> libz.so.1.2.13 lrwxrwxrwx 1 amine amine 14 juin 5 14:30 libz.so -> libz.so.1.2.13 -rwxr-xr-x 1 amine amine 775352 juin 5 14:32 libpng12.so.0.34.0 lrwxrwxrwx 1 amine amine 18 juin 5 14:32 libpng12.so.0 -> libpng12.so.0.34.0 lrwxrwxrwx 1 amine amine 18 juin 5 14:32 libpng12.so -> libpng12.so.0.34.0 -rwxr-xr-x 1 amine amine 966 juin 5 14:32 libpng12.la -rw-r--r-- 1 amine amine 1456748 juin 5 14:32 libpng12.a -rwxr-xr-x 1 amine amine 788504 juin 5 14:32 libpng.so.3.34.0 lrwxrwxrwx 1 amine amine 16 juin 5 14:32 libpng.so.3 -> libpng.so.3.34.0 lrwxrwxrwx 1 amine amine 11 juin 5 14:32 libpng.la -> libpng12.la lrwxrwxrwx 1 amine amine 10 juin 5 14:32 libpng.a -> libpng12.a lrwxrwxrwx 1 amine amine 11 juin 5 14:32 libpng.so -> libpng12.so -rw-r--r-- 1 amine amine 484760 juin 5 14:34 libjasper.so.4.0.0 drwxrwxr-x 2 amine amine 4096 juin 5 14:34 pkgconfig lrwxrwxrwx 1 amine amine 18 juin 5 14:34 libjasper.so.4 -> libjasper.so.4.0.0 lrwxrwxrwx 1 amine amine 14 juin 5 14:34 libjasper.so -> libjasper.so.4 -rw-r--r-- 1 amine amine 116224 juin 5 14:36 libbacio.a -rw-r--r-- 1 amine amine 2387762 juin 5 14:54 libbufr_4.a -rw-r--r-- 1 amine amine 3462538 juin 5 14:57 libw3emc_d.a -rw-r--r-- 1 amine amine 3438778 juin 5 14:57 libw3emc_4.a -rw-r--r-- 1 amine amine 1312444 juin 5 15:02 libg2_d.a -rw-r--r-- 1 amine amine 1308556 juin 5 15:02 libg2_4.a -rw-r--r-- 1 amine amine 2725466 juin 5 15:20 libw3nco_d.a -rw-r--r-- 1 amine amine 2811322 juin 5 15:20 libw3nco_8.a -rw-r--r-- 1 amine amine 2732746 juin 5 15:20 libw3nco_4.a drwxrwxr-x 7 amine amine 4096 juin 5 15:21 cmake i does nt know how export all library in link

[JessicaMeixner-NOAA]

Have you tried using CMAKE in the develop branch instead of the older release?

[aminekhedim]

no i just use current version cmake (of system ubuntu 20.04) to install all libraries

[JessicaMeixner-NOAA]

You might try that to see if you have better luck, with the WW3 CMAKE build finding the other libraries you've installed.

[aminekhedim]

can you send me link for cmake inthe branch develop because I didn t find it

[MatthewMasarik-NOAA]

Hi @Tobyoo, the newest version of WW3, which uses cmake for building, can be downloaded like this:

git clone https://github.com/NOAA-EMC/WW3

Here is a link to the full cmake WW3 build documentation. Within that there is a Quick Start guide. Please try following that guide to clone and build the WW3 executables, and let me know if you are successful.

i m sourced all libraries in bashrc and then I change NOGRB of switch_ifremer1 to NCEP2 hen when I execute command cmake .. -DSWITCH=$HOME/NCEPLIBS/WW3/model/bin/switch_Ifremer1 -DCMAKE=$HOME/ww3_latest -DNETCDF=ON I have his error -- Build with switch: /home/amine/NCEPLIBS/WW3/model/bin/switch_Ifremer1 -- Found NetCDF: /home/amine/libs/include (found version "4.1.2") found components: Fortran -- FindNetCDF defines targets: -- - NetCDF_VERSION [4.1.2] -- - NetCDF_PARALLEL [FALSE] -- - NetCDF_C_CONFIG_EXECUTABLE [/home/amine/libs/bin/nc-config] -- - NetCDF::NetCDF_C [SHARED] [Root: /home/amine/libs] Lib: /home/amine/libs/lib/libnetcdf.so -- - NetCDF_Fortran_CONFIG_EXECUTABLE [NetCDF_Fortran_CONFIG_EXECUTABLE-NOTFOUND] -- - NetCDF::NetCDF_Fortran [SHARED] [Root: /home/amine/libs] Lib: /home/amine/libs/lib/libnetcdff.so -- Found g2: /home/amine/NCEPLIBS/lib/libg2_4.a (found version "3.5.0") -- Found bacio: /home/amine/NCEPLIBS/lib/libbacio.a (found version "2.6.0") -- Found bacio: /home/amine/NCEPLIBS/lib/libbacio.a (found version "2.6.0") -- Found w3emc: /home/amine/NCEPLIBS/lib/libw3emc_4.a (found version "2.11.0") -- Copying switch.io to /home/amine/NCEPLIBS/WW3/build/regtests/unittests -- Copying ww3_grid.inp to /home/amine/NCEPLIBS/WW3/build/regtests/unittests/ww3_grid.inp -- Configuring done CMake Error at model/src/CMakeLists.txt:201 (add_executable): Target "ww3_grib" links to target "bacio::bacio_4" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? REMARK"when I install bacio library it generate just libbacio.a not like g2lib and w3emc generate libw3emc_4.a libw3emc_d.a libg2_4.a libg2_d.a"

[MatthewMasarik-NOAA]

I would suggest looking into whether or not the bacio library is loaded correctly. If dependencies are not satisfied, cmake will not have what it needs to complete the build.
