The full log is in the usual place ( ftp://rudbek.com/pub/boost/status.log ) I attempted to "fix" the lower and upper ambiguous symbols by changing lower(value) to value.lower() and the same for upper(value), but that causes problems later in the compile when apparently some ublas things are being used. .....perhaps the solution will be to add the required methods lower()const and upper()const to the ublas system. at any rate, here are the "interesting" lines: File: status.log ...found 38391 targets... ...using 2 temp targets... ...updating 4251 targets... ...on 100th target... ...on 200th target... ...on 300th target... ...on 400th target...
