deleting of the targets once interrupted.

[bhaskar . g]

Hi All,

This is regarding earlier reported problem when using gmake 3.79.1 on Windows 
and 3.80 on HP UX.

If I implement this using a sed script the problem is not seen. The sed script 
implementation is as follows:

As per the gmake manual if the make process is interrupted using (^c) it will 
delete the currently building
target.

%.d: %.c
      $(_SDE_ECHO)$(ECHO) Making dependencies for $<
      $(_SDE_ECHO)$(MKDIR) $(dir $@)
      $(_SDE_ECHO) if [ x$(_SDE_ECHO) = x ]; then $(ECHO) $(GCC) -undef -M 
$(_SDE_GCC_CXXOPTIONS) $<; fi
      $(_SDE_ECHO)$(GCC) -undef -M $(_SDE_GCC_CXXOPTIONS) $< \
      | $(SED) 's%\(.*\)\.o[ :]*%$(@:.d=.$(_SDE_O)) $@ : %g'> $@; \
      [ -s $@ ] || $(RM) $@

Thanks in Advance for your help.

Hi All,

I am using 3.79.1 on windows with cygwin and encountering the following problem.

my makefile implementation of generating dependency is something like this.

define makecdeps
$(strip $(subst $(_space_)\,$(_space_),$(shell $(GCC) -M $(_SDE_GCC_COPTIONS) 
$<)))
endef

define dependencies
$(patsubst %.o:,$(@:.d=.$(obj)):,$(if $(filter %.c,$<),$(makecdeps))

define run_deps
$(_SDE_ECHO)$(ECHO) Making dependencies for $(notdir $<) ...; \
if [ ! -d $(dir $@) ]; then $(MKDIR) -p $(dir $@); fi; \
$(ECHO) '$@ \'>$@
@$(if $(findstring :,$(dependencies)), $(foreach file,$(dependencies),$(ECHO) 
'$(file) \'>>$@ ;),$(ECHO) ': \'>>$@ ;)
@if [ ! -s $@ ]; then $(RM) -Rf $@; fi
endef

%.d: %.c
      $(run_deps)

When i try to generate the dependency and i would like to interrupt gmake by 
ctrl-c. The following happens
it pops a message saying that deleting <filename>.d file but the file is still 
present and with some of the contents.

Do anyone have any idea what is being done.

regards
bhaskar
