# Build script for libuv (autotools, Template A variant + autogen.sh).
#
# GOTCHA (1b-2): the release tarball ships NO pre-generated `configure`
# (only configure.ac/Makefile.am + autogen.sh) - must autogen before the
# usual libtool-fix + configure steps. Same shape as base/x11vnc's
# autoreconf gotcha.
#
# GOTCHA (1b-2): libuv's configure.ac gates its illumos backend
# (src/unix/sunos.c, `AM_CONDITIONAL([SUNOS], ...)`) on `$host_os` matching
# the literal pattern `solaris*`. Our BUILD_TRIPLE's OS component is
# "hammerhead" (x86_64-zygaena-hammerhead), which doesn't match, so
# unpatched the port silently builds without the SunOS backend at all
# (missing symbols / broken kqueue-less unix core). Patch the
# AM_CONDITIONAL pattern to also match hammerhead* before autogen.sh runs
# (configure.ac -> configure, so this must happen pre-generation, not as
# a `sed` on the generated `configure` like the libtool fix below).
