For each .o file in the source dir after building, do: eu-readelf -S foo.o And then then output for each .o file must contain a .note.GNU-stack section, if it doesn't then that .o file is the culprit of then flags part of the .note.GNU-stack section contains a .o file then that .o file is (one of) the culprit(s) too even though it has a .note.GNU-stack section. Most of the time the problem .o files are files generated from asm code. Once you've got a list of troublesome source files drop me a mail and I'll explain the next step in fixing this. Regards, Hans
