# MAKEFILE for linux GCC

# Modified by Clay Culver
#
# NOTE: This should later be replaced by autoconf/automake scripts, but for
# the time being this is actually pretty clean. The only ugly part is
# handling CFLAGS so that the x86 specific optimizations don't break
# a build. This is easy to remedy though, for those that have problems.

# The version
VERSION=0.95

#ch1-01-1
# Compiler and Linker Names
#CC=gcc
#LD=ld

# Archiver [makes .a files]
#AR=ar
#ARFLAGS=r

#ch1-01-3
# Compilation flags. Note the += does not write over the user's CFLAGS!
# The rest of the flags come from the parent Dropbear makefile
CFLAGS += -c -I./
# -Werror

# optimize for SPEED
#CFLAGS += -O3 -funroll-loops

#add -fomit-frame-pointer.  v3.2 is buggy for certain platforms!
#CFLAGS += -fomit-frame-pointer

# optimize for SIZE
#CFLAGS += -Os

# compile for DEBUGING
#CFLAGS += -g3
#ch1-01-3

#These flags control how the library gets built.
