bug#9403: [emacs] [./configure error] Emacs hasn't been ported to `powerpc-gnu-linux-uclibc' systems

[Douglas Mencken]

I got this while building GNU/Emacs.
I supposed it's very portable.
In MACHINES file, I can read that only Yellow Dog distro is supported,
regardless of everything...

Of course, all of the above is just plain *false*.

With the following sed command:
sed -i 's/powerpc\*-\*-linux-gnu\*/powerpc*-*-linux-*/' ./configure.in
I've been able to get working GNU/Emacs, even with Snake game :)

Configured for `powerpc-gnu-linux-uclibc'.

  Where should the build process find the source code?
/root/build-farm/emacs-v23.3.builddir
  What operating system and machine description files should Emacs use?
        `s/gnu-linux.h' and `m/macppc.h'
  What compiler should emacs be built with?
powerpc-gnu-linux-uclibc-gcc  -O3 -Wdeclaration-after-statement
-Wno-pointer-sign
  Should Emacs use the GNU version of malloc?             yes
  Should Emacs use a relocating allocator for buffers?    yes
  Should Emacs use mmap(2) for buffer allocation?         no
  What window system should Emacs use?                    none
  What toolkit should Emacs use?                          none
  Where do we find X Windows header files?                NONE
  Where do we find X Windows libraries?                   NONE
  Does Emacs use -lXaw3d?                                 no
  Does Emacs use -lXpm?                                   no
  Does Emacs use -ljpeg?                                  no
  Does Emacs use -ltiff?                                  no
  Does Emacs use a gif library?                           no
  Does Emacs use -lpng?                                   no
  Does Emacs use -lrsvg-2?                                no
  Does Emacs use -lgpm?                                   yes
  Does Emacs use -ldbus?                                  no

bug#9403: Emacs hasn't been ported to `powerpc-gnu-linux-uclibc' systems

Thanks for the bug report.  The configure.in and MACHINES stuff is no
longer present in the trunk so I guess that's been fixed already.
I just now removed the obsolete mention of the Yellow Dog issue from
etc/PROBLEMS, as part of bzr 105613:

http://bzr.savannah.gnu.org/lh/emacs/trunk/revision/105613

I think that should finish the job, so I'm marking the bug as done.

AFAICS, it remains true that nothing in configure.in will match
$canonical = "powerpc-gnu-linux-uclibc". The minimal change would be:

*** configure.in	2011-08-26 07:12:16 +0000

Thanks, I put in the following slightly-more-conservative patch as bzr 105618,
as I'm not sure what would work with non-GNU Linux ports.

* configure.in (opsys): Add pattern *-gnu-linux*
to recognize powerpc-gnu-linux-uclibc (Bug#9403).

That's not correct.  The -gnu- in the example is the (free form) vendor
part.  What matters is -linux-uclibc, ie. you fail to match
powerpc-unknown-linux-uclibc which is the canonical form of
powerpc-linux-uclibc.

Thanks, I changed it to *-*-linux* as you suggested, and
removed some related obsolete HP patterns, as follows:
