[netcdfgroup] undefined reference to `H5Pset_fapl_http' and `H5FD_http_init'

[Vesselin Kolev <vlk@xxxxxxxxxxxxxxxxx>]

Hello Everyone,

I face very strange problem when compiling NetCDF-C 4.8.0 against 
HDF5-1.10.7 and HDF5-1.12.1.

Note that HDF5 is compiled in the following manner:

LDFLAGS="-L/opt/software/zlib/1.2.11/lib" 
CFLAGS="-I/opt/software/zlib/1.2.11/include" 
CXXFLAGS="-I/opt/software/zlib/1.2.11/include" 
FCLAGS="-I/opt/software/zlib/1.2.11/include" 
ZLIB_ROOT=/opt/software/zlib/1.2.11 FC=mpifort FCFLAGS="-Ofast" CC=mpicc 
CFLAGS="-Ofast" CXX=mpic++ CXXFLAGS="-Ofast" cmake .. 
-DCMAKE_INSTALL_PREFIX=/opt/software/hdf/5/1.10.7-gcc_11-zlib_1-api_v18-mpich_3 
-DHDF5_ENABLE_THREADSAFE=OFF -DHDF5_BUILD_CPP_LIB=OFF 
-DHDF5_BUILD_FORTRAN=ON -DHDF5_BUILD_HL_LIB=ON -DHDF5_BUILD_JAVA=OFF 
-DHDF5_ENABLE_Z_LIB_SUPPORT=ON -DBUILD_SHARED_LIBS=ON 
-DDEFAULT_API_VERSION=v18 -DHDF5_ENABLE_PARALLEL=ON

using GCC 11.0.3. Also note, that the HDF5 compilation passed the 
post-compilation tests without any fail.

But if I try to compile NetCDF-C agains that particular compilation of HDF5:

LDFLAGS="-L/opt/software/hdf/5/1.10.7-gcc_11-zlib_1-api_v18-nojava/lib" 
CC=gcc CFLAGS="-Ofast 
-I/opt/software/hdf/5/1.10.7-gcc_11-zlib_1-api_v18-nojava/include" 
./configure --prefix=/opt/software/netcdf-c/4/4.8.0-gcc_11_hdf5_1.10.7 
--enable-mmap --enable-byterange

I get the following error:

../liblib/.libs/libnetcdf.so: undefined reference to `H5Pset_fapl_http'
../liblib/.libs/libnetcdf.so: undefined reference to `H5FD_http_init'

Any suggestions where to look for the source of the problem are greatly 
welcomed.

Thank you very much in advance!

Best,
