 There are binaries available, and they're probably fine, but the headers are not, because HDF4 / HDF5 install different headers depending on which compiler they were built with (which in itself is a bug).  Luckily, building them from source is fairly easy.
-**TODO:** Figure out the exact relationship between these three.  Apparently, HDF4 wants NetCDF, and NetCDF wants HDF5...
+Yeah, right.  Actually, [[windows:building:hdf4|HDF4]] is a nightmare, so we've left it out.
 ===== NetCDF =====

-===== HDF4 =====
-First, get the latest source (currently 4.2r4) from http://www.hdfgroup.org/release4/obtain.html and extract it in a convenient place.
-HDF4's autoconf infrastructure is outdated and partly broken.  Open ''configure.ac'', look for "Libtool initialization" (around line 660) and replace the following two lines
-  LT_INIT(dlopen)
-  LT_OUTPUT
-with this one:
-  AC_PROG_LIBTOOL
-Next, there is a spot in ''configure.ac'' that checks which OS you're running on and bails if it doesn't recognize it...  which is stupid, because it controls code that is only used *only* if you want to use HDF4's own version of NetCDF, which we don't.  We can work around this by changing ''cygwin'' to ''mingw32'' on line 695.  It's wrong, but it doesn't matter, because the result is never used.
-Then regenerate everything:
-  $ aclocal
-  $ libtoolize --copy --force
-  $ autoheader
-  $ automake --add-missing --copy --foreign
-  $ autoconf
-**XXX** automake warns about ''F77LINK'', check if that requires fixing.
-Finally, configure, build and install:
-  $ LDFLAGS=-no-undefined ./configure --prefix=/opt/hdf --enable-shared --disable-fortran --disable-netcdf
-  $ make all install
-You //must// specify ''%%--disable-netcdf%%'', otherwise HDF4 will install headers which conflict with NetCDF!
-**TODO:** check configure options
 ===== HDF5 =====

-After editing the various ''Makefile.am''s, we need to regenerate the ''Makefile.in''s that ''configure'' uses:
+Finally, HDF5's ''configure.in'' uses the ''LT_INIT'' macro, which only works with very recent versions of automake.  Edit ''configure.in'' and replace these two lines:
+  LT_PREREQ([2.2])
+  LT_INIT([dlopen])
+with this:
+  AC_LIBTOOL_DLOPEN
+  AM_PROG_LIBTOOL
+**XXX** alternative: use more recent [[windows:building:autotools|autotools]] versions, but this has repercussions for all other components
+Now we need to regenerate everything:
   $ aclocal
-  $ automake
+  $ libtoolize --copy --force
+  $ autoheader
+  $ automake --add-missing --copy --foreign
+  $ autoconf
 The fourth and final issue is that C++ support is not enabled by default.  To enable it, add ''--enable-cxx'' to the ''configure'' command line.
