lib/erl/build/otp_subdir.mk

# Comment by tfee 2004-07-01
# ==========================
# This file is a mod of the stock OTP one.
# The change allows make to stop when a compile error occurs.
# This file needs to go into two places:
#     /usr/local/include/erlang
#     /opt/OTP_SRC/make
#
# where OTP_SRC is a symbolic link to a peer directory containing
# the otp source, e.g. otp_src_R9C-2.
#
# After installing OTP, running sudo make install in otp/build
# will push this file out to the two places listed above.
#
# The mod involves setting the shell variable $short_circuit, which we
# introduce - ie it is not in the stock file. This variable is tested
# to affect execution flow and is also returned to affect the flow in
# the calling script (this one). The latter step is necessary because
# of the recursion involved.
