To report a non-security related issue, please provide:

• the version of the software with which you are encountering an issue
  4.6.1

• environmental information (i.e. Operating System, compiler info, java version, python version, etc.)
  ubuntu 22.04.4
  HDF5_Version=1.14.4
  HDF5_Sub_Version=2
  Zlib_Version=1.3.1
  Netcdf_C_Version=4.9.2
  Netcdf_Fortran_Version=4.6.1
  Mpich_Version=4.2.1
  Libpng_Version=1.6.39
  Jasper_Version=1.900.1
  Pnetcdf_Version=1.13.0

• a description of the issue with the steps needed to reproduce it
  When compilling netcdf-fortran && netcdf-c with the -lgfortran flag it raises an error saying unable to compile using intel llvm compilers.
  When using the intel classic compilers it did not have this issue. Which is intel compilers before 2023

I would think that the gnu compilers wouldn't cause a problem because the -lgcc linker can be in the CFLAGS command and it doesn't cause it to break. Only the -lgfortran.

Some relevant code that I am using:

	cd "${WRF_FOLDER}"/Downloads
	tar -xzvf v$Netcdf_C_Version.tar.gz
	cd netcdf-c-$Netcdf_C_Version/

	# these variables need to be set for the NetCDF-C install to work
	export CPPFLAGS=-I$DIR/grib2/include
	export LDFLAGS=-L$DIR/grib2/lib
	export LIBS="-lhdf5_hl -lhdf5 -lz -lcurl -lgcc -lm -ldl -lpnetcdf"
	autoreconf -i -f 2>&1 | tee autoreconf.log

	CC=$MPICC FC=$MPIFC CXX=$MPICXX F90=$MPIF90 F77=$MPIF77 CFLAGS=$CFLAGS ./configure --prefix=$DIR/NETCDF --disable-dap --enable-netcdf-4 --enable-netcdf4 --enable-shared --enable-static --enable-pnetcdf --enable-cdf5 --enable-parallel-tests 2>&1 | tee configure.log
	automake -a -f 2>&1 | tee automake.log
	make -j $CPU_HALF_EVEN 2>&1 | tee make.log
	make -j $CPU_HALF_EVEN install 2>&1 | tee make.install.log

	# other libraries below need these variables to be set
	export PATH=$DIR/NETCDF/bin:$PATH
	export NETCDF=$DIR/NETCDF

@WardF

Here's my issue that I opened with all the log files.

@edhartnett @WardF

not sure why the linker for gfortran doesn't work. Seems to affect all versions of netcdf including cxx. Maybe it's an intel llvm problem?

[WardF]

Thanks for your patience; the netCDF-C release has been demanding a lot of my time. Let me review this.

[HathewayWill]

that's okay take your time, just trying to help @WardF
