# MINGW32 Makefile for EPANET

# This will build EPANET as DLL
# (epanet2.dll) under MINGW32 GCC, and a standalone
# executable (epanet2d.exe).

# The following targets are defined:
# make
#     -Builds epanet2.dll, epanet2d.exe
# make install
#     -Copy epanet2.dll, epanet2d.exe, epanet2.def to $(prefix)
# make clean
#     -Removes object and library files, returning the build directory
#      to its pristine state.

# You may wish to change the install path 'prefix',
# or the compiler flags, but these defaults should be fine.
