Kai,
Rebuilt Geos with your insight, and two spaces between all -D entries,
including eliminating MrSid that was complied under gcc 521 or so and
might likely cause problems, using GDAL build hints
<https://gdal.org/build_hints.html>, and we have success on on *target
gcore_mdreader*, and I'll move on to sorting out what is wrong with
missing symbols in whatever provides 'nc_open_mem', viz:
[ 89%] Built target gcore_mdreader
[ 89%] Linking CXX shared library libgdal.so
/usr/bin/ld:
frmts/netcdf/CMakeFiles/gdal_netCDF.dir/netcdfdataset.cpp.o: in
function `netCDFDataset::Open(GDALOpenInfo*)':
netcdfdataset.cpp:(.text+0x283d4): undefined reference to `nc_open_mem'
/usr/bin/ld: netcdfdataset.cpp:(.text+0x2852a): undefined reference to
`nc_open_mem'
nc_open_mem is provided by the netCDF library. Your issue might come
perharps from doing an initial cmake run with some netCDF version that
includes that symbol , and re-running with an older one that hasn't it,
and then cmake is confused becaused it has kept in cache that the netCDF
lib has the nc_open_mem symbol. Removing CMakeCache.txt and re-running
would solve it.
Looks like updating libnetcdf...or perhaps not netcdf won't play nice
with hdf5-1.12.1 till 4.9 dist release
<https://github.com/Unidata/netcdf-c/issues/2166> so drop netcdf for now.
And have to figure out turning off DODs, but wow, spotting a missing
space, I'd have to perl that or something. But, have now arrived at:
Which version of libdap do you use ? Note that support for DODS is
likely to be dropped as we lack maintainers for it (see
https://github.com/OSGeo/gdal/issues/5173)
[ 86%] Built target gcore_mdreader
[ 86%] Linking CXX shared library libgdal.so
/usr/bin/ld: frmts/dods/CMakeFiles/gdal_DODS.dir/dodsdataset2.cpp.o:
in function `get_variable(libdap::DDS&,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&)':
dodsdataset2.cpp:(.text+0x624): undefined reference to
`libdap::www2id(std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&,
std::__cxx11::basic_string<char, std::char_traits<char>,
std::allocator<char> > const&, std::__cxx11::basic_string<char,
std::char_traits<char>, std::allocator<char> > const&)' <------snip
and appears -DGDAL_ENABLE_DRIVER_DODS:BOOL=OFF is not doing it.
That's weird... Note that there's also a OGR DODS driver, so to fully
remove any DODS support -DOGR_ENABLE_DRIVER_DODS:BOOL=OFF would be
needed too
