# The below settings work on FreeBSD. Other UNIX-like systems should only
# require minor tweaks (e.g. LIB_PATH on Debian should be /usr/lib/ rather than
# /usr/local/lib/ and the compiler is gcc rather than cc).
CC       = cc
CC_FLAGS = -Wall -pedantic -std=c99
INC_PATH = -I../../screenhack/ -I/usr/local/include/
LIB_PATH = -L/usr/local/lib/
LIBS     = -lm -lX11 -lXt

# Many of the X-related header files contain named variadic macros. Suppress
# that warning so that we can enable -pedantic C89 compliance for our own code.
CC_FLAGS += -Wno-variadic-macros

# Binary literals are not part of C, yet are used liberally in NEDsim.
CC_FLAGS += -Wno-gnu-binary-literal

# These flags are normally set in config.h which is generated by the autoconf
# script as the initial step of the xscreensaver build process. The flags
# enable/disable code in the various screenhack library files. When compiling
# elsewhere than FreeBSD, these flags will likely need to be changed.  If
# you're having trouble determing the correct flags to use, try running
# './configure' in an xscreensaver source tree and examining the generated
# config.h file.
DEFINES  = -DGETTIMEOFDAY_TWO_ARGS -DHAVE_UNISTD_H

# Since we're only building standalone hacks (i.e. building outside the
# xscreensaver tree/process) for testing and will later integrate them into the
# xscreensaver source tree, for now we simply slurp up all the C files that
# comprise the screenhack library and link them directly into the binary.

# Create NED_OBJ containing a list of object files with embedded NED1 machine
# code which should be linked to the NEDsim binary.
