@skew-t Is it possible that you are using clang instead of gcc? I'm able to get the same error if I do CC=clang makepkg, as clang doesn't include omp.h while gcc does.

Interesting, the build fails for me without openmp installed with: Ncpu.c:13:10: fatal error: 'omp.h' file not found. It looks like the cmake config does not set USE_OPENMP to off from the default when the libraries are not found.

@skew-t Ah I see, the build does check for openmp but seems to succeed even if it's not present. Will look into how to deal with this when I have some more time.

@Alfred456654 Good catch, this has been fixed.

@skew-t I don't think this is true; wgrib2 is running on my system now and I don't have openmp installed.

openmp appears to be a dependency as well

netcdf-cxx should be added as a dependency. It's not possible to build wgrib2 without it as of v3.4.0-1.

Uses the built-in statically linked libraries instead of trying to modify the makefile to work with Arch dependencies. See https://ftp.cpc.ncep.noaa.gov/wd51we/wgrib2/_README.nolib for details.

Never able to install this package. Found a temp solution myself as shown below:-

1. Downloaded the latest pre-compile wgrib2 binary from anaoconda repo https://anaconda.org/conda-forge/wgrib2/files.

2. The binary expected libjasper.so.1 and libmysqlclient.so.18 but Arch had only libjasper.so and libmysqlclient.so

3. Made a soft link point to Arch Linux libraries as indicated below:- sudo ln /usr/lib/libmysqlclient.so /usr/lib/libmysqlclient.so.18 and sudo ln -s /usr/lib/libjasper.so /usr/lib/libjasper.so.1

4. Executed wgirb2 and it happily printed the list of available options.

5. Hope it helps someone scratching their head for the answer.

Does not compile. Received the following error:-
