# Makefile to create a shared-object file for use with the "dsp486" command
#
# To compile the shared object file, make any appropriate changes below 
# and type "make" at the command-line prompt.  (this should create the 
# "libdsp.so" file that the dsp486 command will look for.)


#
# Normally, only the LOBJS line should be modified, so that all needed
# files are included in the shared object file...  This file is written
# assuming that the plugin routines are stored in "dsp.c", and that no
# other source files are required.
#
# To link to additional source code files (For example, "subs1.c", "subs2.c"
# and "my_fir_filter_routines.c", replace the LOBJS line with something like:
#   LOBJS=dsp.o subs1.o subs2.o my_fir_filter_routines.o
# 
# (Notice that the ".c" extension has been replace with ".o"
#
LOBJS=dsp.o


# Don't change this name...dsp486 will look for "libdsp.so"

# The CFLAGS part of the following includes "-g" to support symbolic debugging.
# But this also prevents any compiler optimization.  Removing "-g" (after you've
# debugged your code!) should improve the execution time of your program.
#
# If you want the compiler to work hard to optimize the executable, try replacing 
# "-g" with "-O1", "-O2", or "-O3".
