* build-sys: simplify UL_ENABLE_ALIAS() semanticKarel Zak2017-02-211-2/+2
| | | | | | | | Let's follow only $enable_ variables. In this case the MASTERNAME (e.g. [schedutils] for --enable-schedutils) has to be without UL_BUILD_INIT. Signed-off-by: Karel Zak <kzak@redhat.com>
* build-sys: fix --disable-all-programs --enable-schedutilsKarel Zak2017-02-201-0/+15
| | | | | | | | | | | | | * add UL_ENABLE_ALIAS(NAME, MASTERNAME) to initialize $enable_<name> according to MASTERNAME. Note that we have to use $build_<mastername>, the $enable_<mastername> is just AC_ARG_ENABLE() stuff only. The $build_ is evaluated and modified by our UL_...() functions. * add enable-schedutils.conf to have build-system regression test for this use-case Addresses: https://github.com/karelzak/util-linux/issues/415 Signed-off-by: Karel Zak <kzak@redhat.com>
* build-sys: cleanup UL_NCURSES_CHECKKarel Zak2016-12-131-21/+33
| | | | | | | | * use SUFFIX for upper-case suffix * use AC_CHECK_TOOL() to search for ncurses-config (thanks to Mike Frysinger) * separate checks by AS_IF() Signed-off-by: Karel Zak <kzak@redhat.com>
* build-sys: prefer pkg-config for ncursesKarel Zak2016-12-121-20/+28
| | | | | | and use ncurses{5,6}-config as fallback only. Signed-off-by: Karel Zak <kzak@redhat.com>

* build-sys: use ncurses-config rather than pkg-configKarel Zak2016-10-201-0/+35
| | | | | | | | | | It's painful, but ncurses upstream does not distribute .pc files by default and it seems that ncurses{6,5}-config is the preferred solution. For better compatibility lets use ncurses-config. Reported-by: Ruediger Meier <sweet_f_a@gmx.de> Signed-off-by: Karel Zak <kzak@redhat.com>

* build-sys: allow autoconf < 2.64 to be usedKir Kolyshkin2015-09-031-0/+26
| | | | | | | | | | | | | | | | | | | | | | | Since commit 50d096a macro m4_ifblank is used, but as it is only available in autoconf-2.64, on CentOS 6 system we end up with: > $ ./autogen.sh > configure:25396: error: possibly undefined macro: m4_ifblank > If this token and others are legitimate, please use > m4_pattern_allow. > See the Autoconf documentation. > [root@kir-ovz2 util-linux]# autoconf --version > autoconf (GNU Autoconf) 2.63 So, the obvious thing to do would be to raise AC_PREREQ to 2.64 in configure.ac. But, given the facts that - autoconf 2.64 is not available for RHEL/CentOS 6, - the only need is one small macro, it's better to just add the missing macro. While at it, add the m4_ifnblank, too.
