           Summary: manual page install broken with old Pod::man
           Product: gcc
           Version: 3.4
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: other
        AssignedTo: unassigned at gcc dot gnu dot org
        ReportedBy: cgd at broadcom dot com
                CC: gcc-bugs at gcc dot gnu dot org
 GCC build triplet: mips64-unknown-linux-gnu
  GCC host triplet: mips64-unknown-linux-gnu
GCC target triplet: mips64-unknown-linux-gnu

(this was a native build on mips64-linux-gnu.  Only configure arg
was --prefix=/my/test/dir)

my test system here has an old version of Pod::man.  Configuring
a combined source tree (gcc + binutils + gdb + expect) checked out
w/ date spec -D "2003-10-22 00:00 UTC", a log of the configure/build output
indicates:

configure: warning: 
*** Makeinfo is missing or too old.
*** Info documentation will not be built.
checking for recent Pod::Man... no

\x18Lack of a recent Pod::Man causes GENERATED_MANPAGES in gcc/Makefile to
be set to <nothing>.

When installing manual pages, install-man tries to install (for instance):
$(docobjdir)/gcc.1

However, that file doesn't exist.  Normally it would be generated by
generated-manpages (i.e., GENERATED_MANPAGES would be set to that, and that
would cause the generated man pages to be generated via dependencies).

I'm not sure what The Right Thing here is.  If i had to guess, i'd say it
would be get rid of GENERATED_MANPAGES entirely, and change the rules which
generate the manual pages, e.g.:

$(docobjdir)/%.1: $(docdir)/%.texi stmp-docobjdir
        $(STAMP) $@
        -$(TEXI2POD) $< > $(basename $(notdir $@)).pod
        -($(POD2MAN) --section=1 \
                        $(basename $(notdir $@)).pod > $(@).T$$$$ && \
                mv -f $(@).T$$$$ $@) || \
                (rm -f $(@).T$$$$ && exit 1)
        -rm -f $(basename $(notdir $@)).pod

to do **somethine** useful if POD2MAN is unusable.  From my POV, the best
behaviour would be to copy a preformatted version from the source tree.

Another alternative would be to rearrange the manual page installation targets
to not try to install manual pages that couldn't be built.

------- Additional Comments From cgd at broadcom dot com  2003-10-22 18:29 -------
investigating this, it looks like this is fallout from:

2003-10-20  Kelley Cook  <kcook@gcc.gnu.org>

        * Makefile.in: Get parsedir and docobjdir from configure.
        * configure.in: Recogonize --enable-generated-files-in-srcdir.
        Pass along parsedir and docobjdir.
        * configure: Regenerate.
        * doc/install.texi: Document --enable-generated-files-in-srcdir.


that patch ultimately causes docobjdir to be set to a dir in the obj tree
if --enable-generated-files-in-srcdir isn't set.  But it doesn't do anything
to create the manual pages there if the manual-page-generation tools
aren't up to date.

(BTW, I think it's **great** that the files won't be generated in the source
directory any more, but IMO it should still be possible to build/install GCC
without being able to regen all generated files.)

oh, also, forgot to mention, on the same system a build/install last
worked w/ sources as of 2003-10-19 00:00 UTC.

I'm pretty sure fixing this correctly will depend on 12744.

Which at this point will be resolved by copying the bison source files and any
generated info files, if they exist into the build tree.
