But this was not my intial problem, instead the build is was failing
during the building of the dependency -- the following command fails.
(Segmentation fault)

	@echo \# auto-depends file > .tmpdepend
	$(TOOLS_PATH)/$(MKDEP_ENGINE) $(CARD_HPATH) \
	`find $(TOPDIR) -follow -name \*.h -print` > .hdepend


The problem seems to be that the cygwin command interpreter does not
like the quotes around find.?. I'm guessing it's a problem with newer
cygwins since we a recent version. 

If you place a backslash in front of the "'"'s it works find.. I tried
this in linux too and it takes it without a problem.

I changed my makefile to the following:

	@echo \# auto-depends file > .tmpdepend
	$(TOOLS_PATH)/$(MKDEP_ENGINE) $(CARD_HPATH) \
	\`find $(TOPDIR) -follow -name \*.h -print\` > .hdepend

Chris, you might consider changing it.


Thank you to Joel, Chris and Bill K for your help.

Did Chris answer this?

bare bsp is a special build option for RTEMS that lets the BSP live
outside the RTEMS source tree.  You use two configure options that
have "bare" in the name.  I don't remember them offhand.  But one
specifies the CPU model, the other the bare bsp build mode.
