The problem is there is a missing dependency in the makefiles, which is how it got through in the first place.. and incremental bootstrap failed to show an issue. if you touch libstdc++-v3/src/*.cc the build should succeed. OR start a scratch build with that source. ^ permalink raw reply [flat|nested] 5+ messages in thread
