Hi Paul, > Some information that may be useful for others trying to install > netcdf under Interix (formerly known as OpenNT). Interix is > strictly POSIX and only comes with POSIX include files and libraries. Thanks for the information. I've incorporated it into our "Other Builds of the netCDF Package" web page at http://www.unidata.ucar.edu/packages/netcdf/other-builds.html which is referenced from the FAQ question "What does netCDF run on?" at http://www.unidata.ucar.edu/packages/netcdf/faq.html#platforms We'll consider your suggestion to solve the io.h/unistd.h problem before the next release. --Russ
