# Minor source of incompatibility between jack 1.x and 2.x: some jack
# apps don't add -lpthread to their CFLAGS because they assume jack.pc
# will already include it (it does, in 1.x). So make 2 act like 1:
sed -i '/^Libs:/s,$, -lpthread,' jack.pc.in

# 20201104 bkw: TODO: support --readline. Only used by jack-transport.
# Trouble is, wscript checks only whether it can link with -lreadline.
# Which it can't, because that also requires -ltermcap. But I don't
# see a way to have it check multiple libs at once. I know one way to
# force it (LDFLAGS=-ltermcap in the env), but then we end up linking
# everything with it, which we do not want! Did I ever mention how
# much I hate waf?
