The make code fragment at
http://www.gnu.org/software/automake/manual/html_node/Extending.html#Extending
does not work as expected if you use --program-suffix=-hdr :



     install-exec-hook:
             cd $(DESTDIR)$(bindir) && \
               mv -f prog$(EXEEXT) prog-$(VERSION)$(EXEEXT) && \
               $(LN_S) prog-$(VERSION)$(EXEEXT) prog$(EXEEXT)


error:

mv: cannot stat `./animate': No such file or directory
mv: cannot stat `./compare': No such file or directory
mv: cannot stat `./composite': No such file or directory

Could you please correct the example code and explain us how to be compatible?

The suffix feature (partially) come from Autoconf; see �15.7 "Trans-
forming Program Names When Installing"[1] of the autoconf manual.  You
are correct that this example in the Automake manual is broken if the
user decides to use the feature.

The transformation is communicated to the Makefile as a sed program, so
I think you should be able to make it work with something like this
(untested):

  install-exec-hook:
  	instprog=`echo prog | sed '$(program_transform_name)'`; \
  	  cd $(DESTDIR)$(bindir) && \
  	  mv -f $$instprog$(EXEEXT) $$instprog-$(VERSION)$(EXEEXT) && \
  	  $(LN_S) $$instprog-$(VERSION)$(EXEEXT) $$instprog$(EXEEXT)

Thank you Nick for providing this code.  However, I'm not really convinced that
it would be worth to additionally complicate the example in the manual to cater
to the seldom-used "program name transformation" feature (which I actually
believe is a misfeature in several respects, but that's something for another
thread).

Still, I'd like to hear the community's opinion on this before committing to
a decision, so for the moment being I'm tagging this report with "more info
required" rather than with "will not fix".
