 directory", even git version

automake>= 1.13 (did not test lower than that) dies during make with:
 CCLD     emxp_cm_bl_shell
 rm: cannot remove 'emxp_cm_bl': Is a directory
 Makefile:1070: recipe for target 'emxp_cm_bl' failed

This happens if you have the same name on the containing directory and
in bin_PROGRAMS, like so
  bin_PROGRAMS = emxp_hw_bl
  emxp_hw_bl_SOURCES = emxp_hw_bl/emxp_hw_bl.c

Here is the offending Makefile snippet:
emxp_hw_bl$(EXEEXT): $(emxp_hw_bl_OBJECTS) $(emxp_hw_bl_DEPENDENCIES) $(EXTRA_emxp_hw_bl_DEPENDENCIES) 
	rm -f emxp_hw_bl$(EXEEXT)
	$(AM_V_CCLD)$(emxp_hw_bl_LINK) $(emxp_hw_bl_OBJECTS) $(emxp_hw_bl_LDADD) $(LIBS)

You try to create a program named 'emxp_hw_bl'.

>    emxp_hw_bl_SOURCES = emxp_hw_bl/emxp_hw_bl.c

But that name is already taken by the directory (in which the source 
files resides).

If you think this is a bug, what do you think is the preferable behaviour?

Cheers,
Peter

hmm, I see the problem.

How do I change Makefile.am, with minimal effort as we have alot of them?
Tried 
  bin_PROGRAMS += emxp_hw_bl/emxp_hw_bl
but that gives me:
ne/emxp_ss/emxp_hw_bl/Makefile.inc:14: warning: variable 'emxp_hw_bl_SOURCES' is defined but no program or
ne/emxp_ss/emxp_hw_bl/Makefile.inc:14: library has 'emxp_hw_bl' as canonical name (possible typo)

It looks like you haven't changed variable names e.g. 
'emxp_hw_bl_SOURCES' to 'emxp_hw_bl/emxp_hw_bl_SOURCES'.

Cheers,
Peter
