The log above suggests you were not using recipe specific sysroots? This would therefore only be applicable to morty and earlier? [This issue is founded on x86-64 building, but it does not mean it is only related with x86. Actually this is caused by the defect of the traditional probe mechanism of 'configure', the package configure script try to probe whether has package 'flex' , then some optional actions will be done by it. In this issue, when this probe happens, /usr/bin/flex exists but '/usr/bin/flex.real' has not created for the parallel building, then configure reports the error and exits from building. Since there are no atomic guarantee for the package output during parallel building, so here add this depends] Cheers, Richard -- _______________________________________________ Openembedded-core mailing list [email protected] http://lists.openembedded.org/mailman/listinfo/openembedded-core
