# SliTaz package receipt v2.

PACKAGE="webkit2gtk"
VERSION="2.4.11"
CATEGORY="network"
SHORT_DESC="Web content engine (WebKit2) for GTK+3."

WGET_URL="$WEB_SITE/releases/$TARBALL"
PROVIDE="webkit2gtk-3.0"

# Created for the 64-bit native desktop (modern WebKit2/GTK3 replacing the old
# libwebkit WebKit1/GTK2 which needs gcc49). 2.4.11 is the last autotools
# WebKit2 that matches our gtk+3 3.14 + libsoup 2.x stack (no libwpe/woff2/
# gstreamer-hard-deps yet). i486: 2.4.11 predates the 32-bit JIT removal
# (JSVALUE32_64), so it can build 32-bit; the risk is ld address space at the
# final link -- see the parades block in compile_rules if it OOMs.
