Is necessary before install or update the ncl package, reinstall/rebuild these packages: g2clib, triangle, udunits, hdf4 (>=4.2.14-4). If everything went well in the build, it generates the binary /usr/bin/ncl. For fresh install run 'source /etc/profile' or relogin.

As lesstif is meanwhily practically unmaintained (see and its use is discouraged, this package should switch to openmotif as a dependency instead of lesstif.

Hi guys!, sorry for the delay for the update, but the last version required several changes for fixes the build, please test it. It required the last version of hdf4 (4.2.14-4) updated today with some changes requires for ncl.

NCL 6.5.0 is now the most recent version of NCL. If I get a chance I'll try to update the package build to help out.

Also, I'm trying to get people to support each other and NCL in a Freenode IRC channel #ncl

Hi @OverlixMax, after building the packages if there is not ncl executable is due to any problem in the build, I need some days to have a little free time for update the package and fixes the problems.

I follow the @Maduvi suggestions, and do this steps: 1) I reinstalled hdf4, just checking that szlib is in the /usr/lib directory thanks to libaec package 2) I renamed the files /opt/hdf4/bin/ncdump y /opt/hdf4/bin/ncgen 3) Reinstalled hdf-eos-common 4) Reinstalled hdf-eos2 editing the PKGBUILD to use the /opt/hdf4/bin/h4cc 5) Reinstalled hdf-eos5 with the /usr/bin/h5cc (from community/hdf5) 6) Install ncl changing the dependency of hdf4-nonetcdf to hdf4.

Everything goes OK, but... at the end, there is no ncl executable. All other executable from the ncl package are there (ncl_filedump, ncl_convert2nc, etc...)

What I'm missing?

Due to updates in HDF libraries I ran into some trouble getting this to work. When reinstalling/rebuilding hdf4 remember enabling szlib, disabling netcdf and renaming the ncdump and ncgen binaries it creates (like hdf4-nonetcdf's PKGBUILD used to do). Then reinstall hdf-eos-common. Then hdf-eos2 using installed h4cc. I also used h4cc to compile hdf-eos5 because could not get it to work with h5cc for some reason. Then to compile ncl add options -lsz -ltirpc to definition of HDFlib in Site.local file. This changes the MD5SUM of this file. Also changed hdf4-nonetcdf for hdf4 as a dependency in PKGBUILD.

Thanks for the report @OdinEidolon, fixed.

Maybe one could use this?

Hi @graziano, currently there's not "or" implementation in PKGBUILD for put these options in depends, there are other options like environment variable but is not good idea for options depends, the current option is edit the PKGBUILD before compile it, but I think that the better is choose the best depend package by default. What do you think about that, I only tested with lesstif, with openmotif compile and run fine? do you think that openmotif is better over lesstif?

graziano commented on 2017-11-21 15:29

Can we have an option to have lesstiff or openmotif? Both packages provide same interface and ncl compiles and works just fine also with openmotif.
