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.

[aminekhedim]

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

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

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.
