#      File             : makefile.lnx
#      Purpose          : gcc makefile for AMR floating point
#                       ; standalone encoder/decoder program
#
#                             make [MODE=DEBUG] [VAD=VAD#] [target [target...]]
#
#                         Important targets are:
#                             default           (same as not specifying a
#                                                target at all)
#                                               remove all objects and libs;
#                                               build libraries; then build
#                                               encoder & decoder programs
#                             depend            make new dependency list
#                             clean             Remove all object/executable/
#                                               verification output files
#                             clean_depend      Clean dependency list
#                             clean_all         clean & clean_depend & rm *.a

#                         Specifying MODE=DEBUG compiles in debug mode
#                         (libaries compiled in DEBUG mode will be linked)
#
#                         Specifying VAD=VAD1 compiles VAD option 1
#                         Specifying VAD=VAD2 compiles VAD option 2
#
#                         The makefile uses the GNU C compiler (gcc); change
#                         the line CC=gcc below if another compiler is desired
#                         (CFLAGSxxx probably must be changed then as well)
#
