The make delete-old target is broken with the -j parameter. It just prints the questions, without waiting for user feedback. I know this is not important, but I wanted to mention it: # make delete-old>>> Removing old files (only deletes safe to delete libs) >>> Removing old directories >>> Old directories removedremove /usr/lib/libmytinfow.a? remove /usr/lib/libmytinfow.so? To remove old libraries run '/usr/obj/TPR40-7/i386/usr/src/make.i386/make delete-old-libs'. It's a tad inconvenient because my make.conf contains the following: .if ${.CURDIR:M/usr/src} || ${.CURDIR:M/usr/src/*} .MAKEFLAGS: -j 4 .endif
