Sachko- The error is occurring because the server at http://test.opendap.org:8080/dods/dts is not currently available. The data from this test server is used to do netcdf opendap tests. If you do not need to access opendap data through netcdf, then you can add the flag --disable-dap to your ./configure flags. If you do need access to opendap data, then when you do the "make check" command, change it to "make -i check"; this will force make to ignore errors. You will need to examine the output of "make -i check" to see if there are any non-opendap errors. =Dennis Heimbigner Unidata Ticket Details =================== Ticket ID: CMQ-644633 Department: Support netCDF Priority: Normal Status: Open
