## Makefile to compile examples programs that use the Midifile library.

## Filename:      midifile/Makefile.programs
## Website:       http://midifile.sapp.org
## Syntax:        GNU Makefile
##
## Description:   This Makefile creates example programs which utilize the
##                lib/libmidifile.a library.
##
## To run this makefile, type (without quotes) "make -f Makefile.examples",
## Although it is intended to be used the file "Makefile" which runs this
## makefile with the command "make examples".  Note that you have to first
## create the library file with the makefile "Makefile.library" (by typing
## the command "make library").
##
## Without arguments, this makefile will compile all example programs.
## If you give a program name as an argument, it will compile
## just that program. E.g.: "make -f Makefile.examples blank" or used
## in conjunction with "Makefile", type "make blank", which will
## compile the "./examples/blank.cpp" program and place it in the
## ./bin directory.

## Operating-system specific settings:

ARCH   =
ENV    =
OSTYPE =
ifeq ($(shell uname),Darwin)
   # This is an Apple OS X computer.
   OSTYPE = OSX

   # The MACOSX_DEPLOYMENT_TARGET allows you to compile on newer OS X computers,
   # but allows the code to run on older OS X computers.  In this case the
   # minimum OS version target will be 10.6:
   ENV = MACOSX_DEPLOYMENT_TARGET=10.9

   # The ARCH setting below forces the library to be compiled for
   # 32-bit architectures in OS X.  Uncomment the ARCH variable below
   # if compiling on a 64-bit computer, but you want 32-bit version
   # (for linking with other 32-bit libraries).
   #ARCH = -m32 -arch i386
else
   # This is probably a linux computer.
   OSTYPE = LINUX

   # The ARCH variable has to be set up slightly different for 32-bit compiling:
   #ARCH = -m32
endif

# Cygwin (and MinGW?) adds the string ".exe" to the end of compiled programs.
# so set EXTEN = .exe when compiling in cygwin. (Need a test for cygwin
# so that the EXTEN variable is setup automatically...)
EXTEN     =
# EXTEN   = .exe
