+Build Instructions for NetCDF-C using autoconf/automake/libtool {#netCDF-autotools}
+===========================================
+
+[TOC]
+
+# Overview {#autotools_overview}
+
+A CMake build of netCDF is also supported. Users should consider using
+the CMake build, which builds netCDF on a wider range of platforms,
+include Microsoft Windows with Visual Studio. The autotools based
+build may eventually be retired; users may considering transitioning
+to the CMake build. See \ref netCDF-CMake.
+
+We also provide pre-built binary downloads for the shared versions of
+netCDF for use with Visual Studio.
+
+# Requirements {#autotools_requirements}
+The following packages are required to build netCDF-C.
+
+* netCDF-C Source Code
+* Optional Requirements:
+ * HDF5 Libraries for netCDF4/HDF5 support.
+ * libcurl for DAP support.
+
+
+
+
+
+# The Autotools Build Process {#autotools_build}
+
+There are four steps in the Build Process when using autotools:
+
+1. Configuration: Before compiling, the software is configured based on the desired options.
+2. Building: Once configuration is complete, the libraries are compiled.
+3. Testing: Post-build, it is possible to run tests to ensure the functionality of the netCDF-C libraries.
+4. Installation: If all tests pass, the libraries can be installed in the location specified during configuration.
+
+For users who prefer pre-built binaries, installation packages are available at \ref winbin
+
+## Configuration {#autotools_configuration}
+
+The output of the configuration step are the makefiles which build the library, utilities, and tests.
+
+### Common Configure Options {#autotools_common_options}
+
+| **Option** | **Autotools** | **CMake** |
+| :------- | :---- | :----- |
+Specify Install Location | --prefix=PREFIX | -DCMAKE\_INSTALL\_PREFIX=PREFIX
+Enable/Disable netCDF-4 | --enable-netcdf-4
--disable-netcdf-4 | -DENABLE\_NETCDF\_4=ON
-DENABLE\_NETCDF\_4=OFF
+Enable/Disable DAP | --enable-dap
--disable-dap | -DENABLE\_DAP=ON
-DENABLE\_DAP=OFF
+Enable/Disable Utilities | --enable-utilities
--disable-utilities | -DBUILD\_UTILITIES=ON
-DBUILD\_UTILITIES=OFF
+Specify shared/Static Libraries | --enable-shared
--enable-static | -DBUILD\_SHARED\_LIBS=ON
-DBUILD\_SHARED\_LIBS=OFF
+Enable/Disable Tests | --enable-testsets
--disable-testsets | -DENABLE\_TESTS=ON
-DENABLE\_TESTS=OFF
+Specify a custom library location | Use *CFLAGS* and *LDFLAGS* | -DCMAKE\_PREFIX\_PATH=/usr/custom_libs/
+Enable parallel I/O tests | --enable-parallel-tests | -DNETCDF\_ENABLE_PARALLEL\_TESTS=ON
+
+A full list of options can be found by invoking `configure --help`.
+
+### Configuring your build from the command line. {#autotools_command_line}
+
+The easiest configuration case would be one in which all of the
+dependent libraries are installed on the system path (in either
+Unix/Linux or Windows) and all the default options are desired. In the
+source directory:
+
+> $ ./configure
+
+If you have libraries installed in a custom directory, you will need to
+set the CPPFLAGS and LDFLAGS environment variables to tell the compiler where the
+libraries are installed. For example:
+
+> $ CPPFLAGS=-I/usr/local/hdf5-1.14.3/include LDFLAGS=-L/usr/local/hdf5-1.14.3/lib ./configure --prefix=/usr/local/netcdf-c-4.9.3
+
+#### Building with Parallel I/O. {#autotools_parallel_io}
+
+NetCDF will build with parallel I/O if the C compiler is an MPI
+compiler, and HDF5 was built for parallel I/O. To build netcdf-c for
+parallel I/O, first build HDF5 for parallel I/O, then build netcdf-c
+like this:
+
+> $ CC=mpicc CPPFLAGS=-I/usr/local/hdf5-1.14.3_mpich/include LDFLAGS=-L/usr/local/hdf5-1.14.3_mpicj/lib ./configure --prefix=/usr/local/netcdf-c-4.9.3_mpich --enable-parallel-tests
+
+The parallel I/O tests will only run if the additional configure
+option is used: --enable-parallel-tests. Those tests run (by default)
+with mpiexec, on 4, 16, or 32 processors. If mpiexec cannot be used on
+your login-nodes, a different command can be used to launch the
+parallel I/O tests. Used the --with-mpiexec configure option to set a
+different parallel I/O job launcher:
+
+> $ CC=mpicc CPPFLAGS=-I/usr/local/hdf5-1.14.3_mpich/include LDFLAGS=-L/usr/local/hdf5-1.14.3_mpicj/lib ./configure --prefix=/usr/local/netcdf-c-4.9.3_mpich --enable-parallel-tests --with-mpiexec='srun -A acct_name -q queue_name'
+
+## Setting the HDF5 Plugin Path
+
+Use the --with-plugin-dir= option to set the HDF5 plugin path. This
+path must contain the directory where HDF5 filters have been
+installed. --with-plugin-dir accepts three values:
+
+* yes - use the first directory in environment variable
+HDF5_PLUGIN_PATH (if it is set), or /usr/local/hdf5/lib/plugin (Unix)
+or ${ALLUSERSPROFILE}\\hdfd5\\lib\\plugin (Windows).
+
+* a path - path to be used for plugins.
+
+* no - do not install or use plugins.
+
+## Checking the Configure Summary
+
+At the end of the configure, a summary of the build will be
+output. It's important to check this to ensure that the desired build
+features are accurately set. For example:
+
+
+# NetCDF C Configuration Summary
