bug#17339: [bug-gnu-emacs] emacs-24.3.90: big build report

Subject: bug#17339: [bug-gnu-emacs] emacs-24.3.90: big build report
Date: Thu, 24 Apr 2014 15:07:16 -0600 (MDT)

I have a test lab with about 40 flavors of Unix running on current and
historical CPU architectures.  I have now done more than 70 build
attempts for the new emacs-24.3.90 release of 19-Apr-2014, and
happily, I can report success on most of them.  There remain a few
failures, and on some of the successful systems, I had to make
repeated tries to find option combinations that would produce a
successful build of emacs, including X11 support on all systems.

In NO CASE did I have to resort to editing any file from
emacs-24.3.90.

First, here is a brief list of systems for which I have successful
builds and installations; compiler choices, configure options and
environment variable settings are omitted, but I can supply them
offlist on request.

        --------------------------------------------------

Here are the failing systems:

    GNU/Hurd x86:
        Compilation fails with

        process.c: In function 'handle_child_signal':
        process.c:6228:58: error: 'WCONTINUED' undeclared (first use in this 
function)
            && child_status_changed (p->pid, &status, WUNTRACED | WCONTINUED))
                                                                  ^
        process.c:6228:58: note: each undeclared identifier is reported only 
once for each function it appears in

        The symbol WCONTINUED is not defined in any file under /usr/include.

    NetBSD 5.0.2 x86:
        Compilation fails with

            process.c: In function 'handle_child_signal':
            process.c:6228:58: error: 'WCONTINUED' undeclared (first use in 
this function)
        That symbol is not found in any file under /usr/include.

    SGI IRIX 6.5 MIPS:
        /usr/local/bin/gcc -std=gnu99 -c -Demacs  -I. -I. -I../lib -I./../lib 
-g3 -O2  process.c

        process.c:2003: error: dereferencing pointer to incomplete type
        process.c:2006: error: dereferencing pointer to incomplete type
        process.c: In function `get_lisp_to_sockaddr_size':
        process.c:2070: error: invalid application of `sizeof' to incomplete 
type `sockaddr_in6'
        process.c: In function `conv_lisp_to_sockaddr':
        process.c:2125: error: dereferencing pointer to incomplete type
        process.c:2126: error: dereferencing pointer to incomplete type
        process.c:2128: error: dereferencing pointer to incomplete type
        process.c: In function `server_accept_connection':
        process.c:4024: error: field `in6' has incomplete type

On all three systems, it looks like changes in emacs source code, or
perhaps the configure-time tests, will be needed.  I could see no
--enable-xxx, --disable-xxx, --with-xxx, or --without-xxx option that
would appear to affect the compilation issues in process.c.

Finally, here are problems for which I found workarounds:

(1) On several systems, linking failed with a missing symbol from the
    ImageMagick libraries:

            undefined: PixelSetMagickColor

    The solution was to either

            (a) add the --without-imagemagick option to configure

            (b) build and install the latest ImageMagick release
                (6.8.9-0), and then retry the emacs build

    I've tried both approaches, and work in (b) is continuing.

(2) On NetBSD 6, configure tests for -lpng fail because that library does
    not exist; instead, the vendor provides only -lpng16.  I fooled the
    emacs configure script by creating this symlink:

                    /usr/local/lib/libpng.a: symbolic link to 
`/usr/pkg/lib/libpng16.a'

    so that -lpng is now found.

(3) On MirBSD, configure quits with the error

            Emacs does not support `i386-unknown-mirbsd10' systems.

    The solution was to use the option --build=i386-unknown-openbsd4.9 in
    the configure step.  MirBSD is a derivative of OpenBSD 4.x, and that
    --build option trick has been necessary for a number of other software
    packages.

(4) On some systems (GNU/Linux on Alpha, SPARC, x86, PowerPC-32, and
    PowerPC-64), in the final "make install", I get this error very near
    the end:

            /bin/bash: line 0: [: !=: unary operator expected
            make[1]: Leaving directory '/local/build/bare/emacs-24.3.90/lib-src'

P.S. For a package of this size (410K lines of C, 1620K lines of
Lisp), the portability of emacs is wonderful!  My thanks go to the
great emacs development team who keep it building and working (almost)
everywhere.
