[Buildroot] [PATCH 1/4] package/bind: enable static build

[Fabrice Fontaine]

Static build has been disabled in 2014 with commit
6045904752b06a8b8e52ba8fc2e49a8548964e8d however bind can be built
statically thanks to --without-dlopen so enable it back

[Buildroot] [PATCH 2/4] package/bind: remove threads dependency

[Fabrice Fontaine]

Threads dependency has been added in 2015 with commit
07c1ad4647b6a8e60338fc01ddcb2d629de0ad14 however bind can be built
without threads thanks to --disable-threads

This will break existing defconfigs which did not explicitly enable
BR2_PACKAGE_BIND_SERVER because it was implicitly enabled when
BR2_PACKAGE_BIND=y. But I don't see a good solution to avoid that. We
certainly don't want BR2_PACKAGE_DHCP=y to install the full BIND server.

So to me, it's an acceptable trade-off. I've Cc'ed Arnout, Peter and
Yann to see what they think.

Best regards,

Thomas

 Although not documented anywhere, in my opinion a defconfig is not supposed to
be stable over upgrades. When upgrading, you should use a full config.

 I do the same for the kernel as well.

 I also always do a diffconfig between old and new and try to understand the
differences.

 Arnout

Agreed. The process I follow to upgrade buildroot if (roughly):

    $ make my_foo_defconfig
    $ git pull
    $ make olddefconfig
    $ diff -du .config.old .config
    $ make savedefconfig
    $ git diff   # shows delta in my_foo_defconfig

This sounds all too familiar, too. ;-)

[Buildroot] [PATCH 4/4] package/dhcp: use system bind

[Fabrice Fontaine]

Select bind instead of using the embedded bind libraries. This will help
managing correctly all the bind dependencies such as zlib

The series looks good in principle, but sadly the following defconfig:

BR2_arm=y
BR2_TOOLCHAIN_EXTERNAL=y
BR2_TOOLCHAIN_EXTERNAL_CUSTOM=y
BR2_TOOLCHAIN_EXTERNAL_DOWNLOAD=y
BR2_TOOLCHAIN_EXTERNAL_URL="http://autobuild.buildroot.org/toolchains/tarballs/br-arm-full-2019.02-rc1.tar.bz2"
BR2_TOOLCHAIN_EXTERNAL_GCC_4_9=y
BR2_TOOLCHAIN_EXTERNAL_HEADERS_4_14=y
BR2_TOOLCHAIN_EXTERNAL_LOCALE=y
# BR2_TOOLCHAIN_EXTERNAL_HAS_THREADS_DEBUG is not set
BR2_TOOLCHAIN_EXTERNAL_CXX=y
BR2_INIT_NONE=y
BR2_SYSTEM_BIN_SH_NONE=y
# BR2_PACKAGE_BUSYBOX is not set
BR2_PACKAGE_DHCP=y
# BR2_TARGET_ROOTFS_TAR is not set

fails to build with:

configure: error: Cannot find static libraries at /home/thomas/projets/buildroot/output/host/arm-buildroot-linux-uclibcgnueabi/sysroot/usr/lib
make[1]: *** [package/pkg-generic.mk:231: /home/thomas/projets/buildroot/output/build/dhcp-4.4.1/.stamp_configured] Error 1

Looking at configure.ac sheds some light:

AC_ARG_ENABLE(libtool,
        AS_HELP_STRING([--enable-libtool],
[use GNU libtool for dynamic shared libraries (default is no).]),
        want_libtool="$enableval")

if test "$use_libbind" != "no"; then
        if test "$want_libtool" = "yes" -a \
                ! -f "$use_libbind/lib/libisc.la"
        then
                AC_MSG_ERROR([Cannot find dynamic libraries at $use_libbind/lib])
        fi
        if test "$want_libtool" = "no" -a \
                ! -f "$use_libbind/lib/libisc.a"
        then
                AC_MSG_ERROR([Cannot find static libraries at $use_libbind/lib])
        fi
fi

We are not passing --enable-libtool, so the code checks is libisc.a
exists, and it doesn't because a default build is BR2_SHARED_LIBS=y,
and therefore bind doesn't build/install any static library.

I suppose passing --enable-libtool would work, but I haven't tested.

Best regards,

Thomas

OK, I'll test it and send a v2.
