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,

Vesselin Kolev
