 +**OUT OF DATE** most of these issues have been resolved or worked around, or were only relevant in the initial, experimental phase.
 +
 +===== --prefix =====
 +
 +You'll notice that I recommend installing several components (HDF, NetCDF, Grib...) in their own directories under ''/opt''.  The reason for this is that it makes it easier to clean up spills while working out the build process.  The downside is that although everything will //build// correctly, some components may fail to //run//
 +
 +**XXX is this really an issue?  perhaps we should just build static libraries.***
 +
 +===== Shared libraries =====
 +
 +Windows doesn't have transitive shared library dependencies.  What this means, in plain language, is that you can't assume—as you can on ELF systems—that loading a shared library automatically loads all of //its// dependencies.  Therefore, libtool will refuse to generate shared libraries unless you promise that whenever you load it, you will also load all of its dependencies.  To do that, you must
 +
 +  - place ''LDFLAGS=-no-undefined'' in your environment before running ''configure'', and
 +  - manually load all the required libraries when you aren't using libtool

 +
 +===== Fortran preprocessing =====
 +
 +You may come across something like this:
 +
 +  $ make termchar.o
 +  g77  -g -O2 -pipe -DG77 -c -o termchar.o termchar.f
 +  termchar.f: In subroutine `termchar':
 +  In file included from termchar.f:0:
 +  termchar.f:41: error: undefined or invalid # directive
 +  termchar.f:44: error: undefined or invalid # directive
 +  termchar.f:47: error: undefined or invalid # directive
 +  make: *** [termchar.o] Error 1
 +
 +It means g77 does not pass ''termchar.f'' through the preprocessor.  You have to rename the file to ''termchar.F'', which can be tricky in MSYS:
 +
 +  $ touch foo.f
 +  $ mv foo.f foo.F
 +  mv: `foo.f' and `foo.F' are the same file
 +
 +You can work around this by renaming the file in two stages:
 +
 +  $ mv foo.f foo.f-
 +  $ mv foo.f- foo.F
