The next version of netCDF, 3.6.1, due to be released this month, is the last version of netCDF which does *not* use libtool and automake. Starting with netCDF 4.0, we have a full autotools build. Consequently, I have been doing a lot of work on the configuration for netCDF 4.0, and now would be a good time to include whatever might help with this compile problem. But I am at a bit of a loss as to what might be helpful for me to do... Are there any other libtool-using freeware packages which handle this situation well? If so, what do they do that helps? Thanks! Ed -- Ed Hartnett -- ed@xxxxxxxxxxxxxxxx
