# ---- General comment ----
# This makefile is for t_cose with the OpenSSL crypto library. See
# longer explanation in README.md. Adjust CRYPTO_INC and CRYPTO_LIB
# for the location of the OpenSSL library on your build machine.
# Makefile.common, included below, contains the lists of library, test
# and example object files that are invariant by crypto library.
# ---- QCBOR location ----
# This is for direct reference to QCBOR that is not installed in
# /usr/local or some system location. The path may need to be adjusted
# for your location of QCBOR.
#QCBOR_DIR=../../QCBOR/master
#QCBOR_INC=-I $(QCBOR_DIR)/inc
#QCBOR_LIB=$(QCBOR_DIR)/libqcbor.a
# This is for reference to QCBOR that is installed in /usr/local or in
# some system location. This will typically use dynamic linking if
# there is a libqcbor.so
QCBOR_INC=-I /usr/local/include
QCBOR_LIB=-lqcbor
# ---- crypto configuration -----
# These two are for direct reference to OpenSSL that is not installed
# in /usr/local or some system location. The path names
# may need to be adjusted for your location of OpenSSL
#CRYPTO_INC=-I ../../openssl/openssl-1.1.1b/include/openssl -I ../../openssl/openssl-1.1.1b/include

# /usr/local/ or in some system location.

# ---- other configuration ----
# Use as needed. It has been used to disable features that aren't ready
# or that aren't passing tests
OTHER_OPTS=
# ---- compiler configuration -----
# This makefile uses a minimum of compiler flags so that it will
# work out-of-the-box with a wide variety of compilers. For example,
# some compilers error out on some of the warnings flags gcc supports.
# The $(CMD_LINE) variable allows passing in extra flags. This is
# used on the stringent build script that is in
# https://github.com/laurencelundblade/tdv. This script is used
# before pushes to master (though not yet through an automated build
# process). See "warn:" below.
C_OPTS=-Os -fPIC
# ---- Aggregate includes and options ----
