I had this after the last bigger changes, maybe two weeks ago or so. Went back to maint, all was fine, forth to master, and again the issues. Deleting the build folder did not help, but deleting the whole gnuradio folder and doing a new git clone helped. Ralph. From: Gilad Beeri (ApolloShield) [mailto:address@hidden

I had maybe similar issues with gnuradio recently, and when I not only removed the build folder but the whole gnuradio folder and did a new git clone, it magically went through as if there never had been any issue :) Don't ask how much time I wasted on this one :)))
