I did a full recording of the memory used by each compiler call during the build on an amd64 host. There is indeed one call at 7.7G. There are a bit more than 800 calls, with only 5 calls above 4G and 25 calls above 2G, with an average of 938M and a median of 885M. The biggest calls by decreasing orders are 7.7G, 5.9G, 5.2G, 4.9G and 4G. Therefore I think it makes sense to at least reduce --required-mem to "7.7G,5.9G", or if you do not like decimal numbers to "8G,6G" Regards Aurelien -- Aurelien Jarno GPG: 4096R/1DDD8C9B [email protected] http://aurel32.net
