Description Matt Whitlock 2020-05-07 06:48:21 UTC
libv4l's configure.ac contains a Bashism (use of == operator with test built-in). Thus, configure throws an error when /bin/sh is not Bash. This doesn't cause the build to fail outright, but it may be causing misdetection of features.

AM_CONDITIONAL([WITH_GCONV],        [test x$enable_gconv = xyes -a x$enable_shared == xyes -a x$with_gconvdir != x -a -f $with_gconvdir/gconv-modules])

/var/tmp/portage/media-libs/libv4l-1.18.1/work/v4l-utils-1.18.1/configure: 23600: test: xyes: unexpected operator

Suggest setting CONFIG_SHELL=/bin/bash when running configure. The "unexpected operator" message above is not present when CONFIG_SHELL=/bin/bash.

    media-tv/v4l-utils: Bump to 1.20.0, fix some automagics
    
    The automagic libudev dependency has now been dealt with via a patch
    and udev USE flag. Among other things, this library is needed for the
    DVB utilities so a dvb USE flag has also been added with a
    corresponding dependency on libv4l[dvb]. There may be more automagics
    but I haven't checked yet.

    media-libs/libv4l: Bump to 1.20.0, fix automagics
    
    configure reportedly has some automagic dependencies but only libudev
    makes any difference here and it's only used to build libdvbv5. There
    is already an option for that.
