## Overwriting I think I solved the file overwrite problem by doing light name mangling of the shared library names. With this change the probabilty is very small that installing our filter wrappers in a directory will overwrite code produced by others. ## Default Install Location I have setup the --with-plugin-dir option default to install in the following locations in order of preference 1. If HDF5_PLUGIN_PATH is defined (at build time remember), then the last directory in that path will be where the filter wrapper shared libraries will be installed. 2. Otherwise the default is "/usr/local/hdf5/lib/plugin" (on *nix*) or "%ALLUSERSPROFILE%\\hdf5\\lib\\plugin" for Windows or Mingw. Currently, --with-plugin-dir is disabled by default. I should note that even if I enable it by default, installing netcdf-c will still not run "out of the box" because the hypothetical naive user will not know which compressor libraries need to be pre-installed before netcdf is installed. Nor will that user have any way to find out what needs to be installed.
