Re: To stupid to install tramp...

Hello Kai,

not sure whether to keep this on the list or not, but for now I'll
just do so...

Not to me.  Indeed, my first thought had been: "Why, this Makefile
doesn't contain any proper install rule at all", and if I hadn't come
up with the idea to try a newer make (which I happened to have lying
around) I might still think so.  Let's see what happenes:

kogs2>/software/tramp-2.0.35/tramp-2.0.35% ./configure --with-emacs 
--prefix=/software/tramp-2.0.35 
--with-lispdir=/software/tramp-2.0.35/share/emacs/21.1/site-lisp
configure: Tramp 2.0.35
checking whether make sets $(MAKE)... yes
checking for emacs... emacs
checking for the Emacs flavor... emacs
checking for makeinfo... makeinfo
checking for reasonable makeinfo version... ok
checking for texi2dvi... texi2dvi
checking for reasonable texi2dvi version... ok
checking prefix... /software/tramp-2.0.35

checking lispdir... /software/tramp-2.0.35/share/emacs/21.1/site-lisp
checking infodir... $(prefix)/info
checking for installation chapter... texi/trampinst.texi
configure: creating ./config.status

config.status: creating contrib/Makefile
config.status: creating lisp/Makefile
config.status: creating lisp/trampver.el
config.status: creating texi/Makefile
config.status: creating texi/trampver.texi

Ok, let's have a look at the relevant sections of the Makefile:

DIRS            = lisp texi $(if $(USE_CONTRIB), contrib)

.SILENT: all install clean info

.PHONY: all install clean distclean info tags           \
        maintainer-clean cvstag MANIFEST tar xemacs     \
        emacs dist install-html savannah cvs-update

all install: $(CONFIG_FILES)
        for a in ${DIRS}; do                            \
            $(MAKE) -C $$a "EMACS=$(EMACS)"             \
            "EMACS_INFO=$(EMACS_INFO)" $(MAKECMDGOALS); \
        done

So, this is supposed to go into lisp and texi and --- hmm, do a make
there?  Or what is the contents of $(MAKE)?  Maybe there's a "make
install" in there?  Ok, let's see what

Ok, so quite obviously $(MAKE) contains either "make" or "make all",
but not "make install".  So what would

do?

make[1]: Leaving directory `/software/tramp-2.0.35/tramp-2.0.35/texi'

Looks better --- apparently $(MAKE) now contains "make install".  So
somewhere between 3.74 and 3.80 this behavious changed...

So make install now works (this is for Emacs 21.1, and after I create
the directories by hand), but:

kogs2>/software/tramp-2.0.35/tramp-2.0.35% ls -l /software/tramp-2.0.35/info
total 174
-rw-r--r--   1 utcke    tvp        88396 Jul 14 11:45 tramp

Hmm, we're mising a dir-file here, so better run

kogs2>/software/tramp-2.0.35/tramp-2.0.35% install-info 
/software/tramp-2.0.35/info/tramp /software/tramp-2.0.35/info/dir
kogs2>/software/tramp-2.0.35/tramp-2.0.35% ls -l /software/tramp-2.0.35/info
total 176
-rw-r--r--   1 utcke    tvp          701 Jul 14 11:47 dir
-rw-r--r--   1 utcke    tvp        88396 Jul 14 11:45 tramp

BTW, you might be wondering how I managed to create the info-file?

Well, surprisingly enough this error only happenes with the never make
of the two, the relevant part of the error is:

And so on.  So why doesn't this happen with the older make?

make[1]: Entering directory `/software/tramp-2.0.35/tramp-2.0.35/texi'
makeinfo --no-split --footnote-style=end -D emacs -o ../info/tramp tramp.texi
makeinfo --no-split --html -D emacs -o tramp-emacs.html tramp.texi
makeinfo --no-split --html -D xemacs -o tramp-xemacs.html tramp.texi

Hmm, looks like the older make never tries to run texi2dvi, which btw
is:

Hmm, at least for emacs 21.1 I can not currently recreate that error,
so I say we postpone this until I get 21.1 up and running.

Ok, I just forget about xemacs 20.4, not most likely noone is using
that anyway...

Thanks.  The same of course goes for the info directory.

I'll submit a formal bug-report in a seperate mail.

Ups.  Ok, let's see...

Jepp, sure enough, this runs tramp, but then of course suffers from
the same problem as emacs, namely it doesn't recognise that it logged
in.  BTW, this is what the *tramp/ssh kogs1* buffer looks like:

Well, I'll give it a quick run: ... yep, same result, so it seems to

Well, I guess what baffled me is that with the older versions of tramp
(or emacs-rcp, or whatever it was called before that) I newer had any
problems at all, so I figured that this time round I must be doing
something stupid.  But maybe it's just that the more faetures a
package has, the easier it is to break...

Thanks
