# Finance::InteractiveBrokers::SWIG - Makefile for SWIG build

# Copyright (c) 2010-2013 Jason McManus
# Version: 0.08
#
# This is usually invoked by 'perl Makefile.PL && make', but if you need to
# run it separately, you can run it by:
#
#   make -fMakefile.swig [ OPTIONS ]
#
# OPTIONS:
#   IB_BUILD_PATH=/path/to/IBJts        # wherever your un-jar'ed API is
#   SWIG=/path/to/swig                  # path to SWIG binary program
#   IB_API_VERSION=X.XX                 # version of the IB API [def: 9.64]
#
# Pre-existing files:
#   Makefile.swig
#   IBAPI.i
#   IBAPI.cxx
#   IBAPI.h
#   ezembed.h
#   $IB_BUILD_PATH/cpp/PosixSocketClient/EClientSocketBase.cpp
#   $IB_BUILD_PATH/cpp/PosixSocketClient/EPosixClientSocket.cpp
# Intermediate files:
#   EClientSocketBase.o
#   EPosixClientSocket.o
#   IBAPI_wrap.cxx
#   IBAPI_wrap.o
#   IBAPI.o
# Final targets:
#   IBAPI.pm
