# Slackware build script for girara

# 20180903 bkw: Fix build with Russian (and possibly other non-English) locale.

# 20180619 bkw: Update for v0.3.0. Upstream switched from make to meson,
# so this script's no longer compatible with older versions of girara.

# Something in the ninja/meson build stuff is grepping the output of
# some command, looking for a specific string in English. Building with
# e.g. ru_RU.UTF-8 locale breaks it. Meson and ninja are totally new to
# me, so I haven't got a 'proper' fix yet. For now, forcing the locale
# to C allows the build to finish:
LANG=C
LC_ALL=C
export LANG LC_ALL

# upstream claims we need newer glib and gtk+3 libs than Slack 14.2 has,
# but diddling the requirements allows it to build and run OK.
