You're right.

Indeed; I have tried on my machine and it's not either. But there's no
.mwc file in Quoter, only an .mpc file. I should probably have explained
this better in the README (and will do) but this means that you should
replace `mwc-ace' in the previous invocation with `mpc-ace'. Doing this
updates the GNUmakefile.

After installing tao-idl and gperf-ace packages, which are needed as
well for the Quoter example, the Quoter example now fails with:

  GNUmakefile: /home/thomas/Quoter/GNUmakefile.Quoter_Factory_Finder MAKEFLAGS=w

  /usr/share/ace/bin/tao_idl -Ge 1 -Wb,pre_include=ace/pre.h -Wb,post_include=ace/post.h -I/usr/share/ace/TAO -I/usr/share/ace/TAO/orbsvcs -I../../orbsvcs/orbsvcs Quoter.idl
  Quoter.idl:18:28: error: CosLifeCycle.idl: Aucun fichier ou répertoire de ce type
  tao_idl.real: preprocessor "g++" returned with an error
  make[1]: *** [QuoterC.cpp] Erreur 1
  make[1]: quittant le répertoire « /home/thomas/Quoter »
  make: *** [Quoter_Factory_Finder] Erreur 2

because there's no CosLifeCycle.idl in ../../orbsvcs/orbsvcs :(

But that's because the Quoter example uses relative path; if you replace
lines with ../.. in Quoter.mpc with $(TAO_ROOT), so that lines looking:

  idlflags += -I../../orbsvcs/orbsvcs
  includes += ../../orbsvcs/orbsvcs

become:

  idlflags += -I$(TAO_ROOT)/orbsvcs/orbsvcs
  includes += $(TAO_ROOT)/orbsvcs/orbsvcs

Now run mpc-ace again; then make and it compiles fine.

I hope it would have been easier with another example ;-)

I'll fix the README.Debian file.

I'll have a look at these, thanks!

I have never felt the PerlACE was needed and understood it was only
needed for unit tests, but I may be wrong. I'll have another look at
it.

Thanks,
