Patch to make our build system support VPATH builds
2008-10-01 22:21:51
Hi, all

VPATH builds [1] are preferred by some people for the following reasons:

1. They prevent the build process form cluttering your source
directory with all sorts of build files.
2. To remove a build, all you have to do is remove the build directory.
3. You can build the same source multiple times using different
options. This is very useful if you would like to write a script that
will run the test suite for a package while the package is configured
in many different ways (e.g. different features, different compiler
optimization, and so on). It is also useful if you would like to do
the same with releasing binary distributions of the source.

Well, I think this is very desirable, since with VPATH, we can test
building from SAC's source code using different parameters, e.g.
--enable-debug, --enable-readline, --disable-editline
--disable-readline.

I made some effort to make this happen, and the patch is attached. It
is not a big patch anyways. I tested using a few different
combinations of parameters during the ./configure stage, and also in
different directories (e.g. the subdirectory of the source tree, the
parent directory of the source tree, a completely different and deep
directory elsewhere). Everything works OK for me.

Explanation of what a `VPATH build' is:

In a VPATH build, the source distribution is stored in a, possibly
read-only, directory, and the actual building takes place in a
different directory where all the generated files are being
stored. We call the first directory, the source tree, and the
second directory the build tree. The build tree may be a
subdirectory of the source tree, but it is better if it is a
completely separate directory.

    Dear Kuang -

    VPATH is notoriously nonstandard among BSD, GNU and Sun make. Suggest
    that you validate its functioning on all those systems. If
    problematic, it might be too much hassle to make work right, despite
    being potentially attractive for simplifying maintenance.

      Dear George,

      Thanks for pointing this out. I've only tested VPATH builds using GNU
      make on linux only, and it worked. I don't have Solaris or Mac
      machines, so is there anybody who can help me test this patch on
      different operating systems other than linux (hopefully using both GNU
      make and other make programs)? Thanks!

      It is already stated in the `Readme.buildsac' file that `the build
      goes best with GNU development tools, specifically the GNU gcc and the
      GNU make'. I hope that my patch will at least work with GNU make on
      different systems. Hopefully it won't cause problem when using other
      make programs.

      I really like this feature since I can keep my source tree uncluttered
      this, and I don't need to make copies of the source tree (which is big
      and has thousands of files) at anytime.

          Kuang,

          I will try to look at your patches this weekend. I have a all day
          meeting tomorrow.

          Patches I need to look at
          - VPATH - I will test this on the supported systems
          - PAGER - I think the solution George gave is the simplest and most
          straight forward
          If PAGER is defined use that variable, otherwise use the default sac
          paging system.
          - make distclean - Again needs to be tested on the supported systems.

          Patches which should be easy to check
          - tolower/toupper checks in build system
          - segfault on space in header variable

          Patches which look good, no changes
          - closing of the plotting window
          - CTRL-D to quit
          - sachistory string overrun

          I will keep you up to date

          Cheers
          Brian

        Dear All -

        I can confirm a successful vanilla build of Kuangs distribution on
        MacOS 10.3 and on FreeBSD 6.3.

        However, this build fails on a Solaris 5.7 system (due to a possibly
        unrelated problem). Perhaps Arthur can investigate further. My
        results are:

        ./configure
        checking build system type... sparc-sun-solaris2.7
        checking host system type... sparc-sun-solaris2.7

        configure: error: C compiler cannot create executables
        See `config.log' for more details.
        ------------

        gcc is so old (2.7.2) that is fails configure tests using -V.

        Forcing to use Sun cc is OK until subdirectory configure is used; then
        CC gets forgotten:

        The generated Makefiles are so exquisitely baroque as to deter any
        sensible debug effort. Suffice it to say that builds that deviate from
        a default system configuration seem unlikely to work.

          Kuang He,

          The build on my system (OSX/Intel 10.4) fails. The abs_top_srcdir is
          not defined.
          I cannot find a resolution to this, but I will keep looking.

          I needed to rerun the bootstrap script (or autoreconf) as the
          Makefile.in files needed to be regenerated from the Makefile.am files.

          I am using autoconf 2.60 and automake 1.9.6

          Cheers
          Brian

          make on linux only, and it worked. I don't have Solaris or Mac
          machines, so is there anybody who can help me test this patch on
          different operating systems other than linux (hopefully using both
          GNU
          make and other make programs)? Thanks!

          It is already stated in the `Readme.buildsac' file that `the build
          goes best with GNU development tools, specifically the GNU gcc and
          the
          GNU make'. I hope that my patch will at least work with GNU make on
          different systems. Hopefully it won't cause problem when using other
          make programs.

          I really like this feature since I can keep my source tree
          uncluttered
          this, and I don't need to make copies of the source tree (which is
          big
          and has thousands of files) at anytime.

            Kuang He,

            To get it to work I needed to add the following line to confgure.in

            AC_SUBST([abs_top_srcdir])
            AC_SUBST([abs_top_builddir])

            Cheers

            The generated Makefiles are so exquisitely baroque as to deter any
            sensible debug effort. Suffice it to say that builds that deviate
            from a default system configuration seem unlikely to work.

            Dear Brian,

            I have been using autoconf 2.61 and automake 1.10. According to my
            tests, automake v1.9 does not define abs_* series macros [1], but
            automake v1.10 does.

            The reason I used abs_top_srcdir instead of top_srcdir in several
            Makefile.am's is to solve a VPATH problem I could not solve otherwise.
            For example, in libedit/Makefile.am, there is line that reads:

            LIBEDIT_ENV = env CFLAGS="$(CFLAGS)" LDFLAGS="$(LDFLAGS)"
            INSTALL="$(abs_top_srcdir)/config/install-sh"

            If I were to write it using $(top_srcdir), I could not make it work
            for all the following VPATH build cases:

            (1) Build directory is a subdirectory of the source tree:
            cd /path/to/sac/source/code
            mkdir build && cd build
            ../configure

            (2) Build directory is a subdirectory of a subdirectory of the source tree:
            cd /path/to/sac/source/code
            mkdir -p build/test && cd build/test
            ../../configure

            (3) Build directory and source tree are not in the same tree:
            cd /path/to/sac/source/code
            mkdir -p /somewhere/else/build && cd /somewhere/else/build
            /path/to/sac/source/code/configure

            Could you try updating your automake version and try again? Or could
            you figure out a way to solve this problem?

            [1] The autoconf manual indicates that it is autoconf that is
            generating macro like abs_srcdir, abs_top_srcdir, etc.
            http://www.gnu.org/software/autoconf/manual/autoconf.html#Preset-Output-Variables

            It is just automake v1.9 that has not used them (meaning: not
            generating them in Makefile.in's).

              A high percentage of the problems in terms of system compatibility have come

              Is there perhaps a new release that is more robust?

                Dear Arthur,

                There is a new release below, about 4 years newer than the version we are using.

                http://www.thrysoee.dk/editline/libedit-20080712-2.11.tar.gz

                I don't know about its robustness, though.

            Kuang He,

            Updating to automake 1.10 solves the problem.

            Solaris 2.9 works for both in and out of source directory builds
            Intel OSX does as well.
            Linux too.

            George indicated FreeBSD worked as did solaris 5.7
            Kuang He says it works fine on Cygwin

            Overall this looks good to me.

            Unless there are any objections, I will be adding this to the
            repository.

            Cheers
            Brian

            The generated Makefiles are so exquisitely baroque as to deter any
            sensible debug effort. Suffice it to say that builds that deviate
            from a default system configuration seem unlikely to work.

            Suggest that you validate its functioning on all those
            systems. If
            problematic, it might be too much hassle to make work right,
            despite being
            potentially attractive for simplifying maintenance.

            Dear George,

            Thanks for pointing this out. I've only tested VPATH builds using
            GNU
            make on linux only, and it worked. I don't have Solaris or Mac
            machines, so is there anybody who can help me test this patch on
            different operating systems other than linux (hopefully using
            both GNU
            make and other make programs)? Thanks!

            It is already stated in the `Readme.buildsac' file that `the build
            goes best with GNU development tools, specifically the GNU gcc
            and the
            GNU make'. I hope that my patch will at least work with GNU make on
            different systems. Hopefully it won't cause problem when using other
            make programs.

            I really like this feature since I can keep my source tree
            uncluttered
            this, and I don't need to make copies of the source tree (which
            is big
            and has thousands of files) at anytime.


            Best regards,
