# Makefile for NetSurf

#
# Trivially, invoke as:
# make
# to build native, or:
# make TARGET=riscos
# to cross-build for RO.
#
# Tested on unix platforms (building for GTK and cross-compiling for RO) and
# on RO (building for RO).
#
# To clean, invoke as above, with the 'clean' target
#
# To build developer Doxygen generated documentation, invoke as above,
# with the 'docs' target:
# make docs
#
all: all-program
# Determine host type
# NOTE: HOST determination on RISC OS could fail because of missing bug fixes
# in UnixLib which only got addressed in UnixLib 5 / GCCSDK 4.
# When you don't have 'uname' available, you will see:
# File 'uname' not found
# When you do and using a 'uname' compiled with a buggy UnixLib, you
# will see the following printed on screen:
# RISC OS
# In both cases HOST make variable is empty and we recover from that by
# assuming we're building on RISC OS.
# In case you don't see anything printed (including the warning), you
# have an update to date RISC OS build sytem. ;-)
