Hi - thanks for the report. $(ANGIE_FILES) refers to source subdirectory "src/jtag/drivers/angie/", but next to it there is a source file called "src/jtag/drivers/angie.c".
I don't think Automake currently tries to consider the values of EXTRA_DIST, just copies them. So it's probably not plausible to try to detect such a case. If that is really the solution, it should probably be documented (or did I miss it?). This is the spot in the documentation: Agreed. Thanks. I thought that Automake 1.17 had actually disabled such GNU Make built-in rules: Looking at https://debbugs.gnu.org/cgi/bugreport.cgi?bug=64743, I guess the auto-compilation of foo.c into foo must be a different implicit pattern rule that we failed to disable. The list of what got disabled was: %:: %,v %:: RCS/%,v %:: RCS/% %:: s.% %:: SCCS/s.% Have to do some research to see what should be added. If possible. Thanks again for the report. -k
