# Makefile for NetSurf

# Copyright 2007 Daniel Silverstone <dsilvers@netsurf-browser.org>
#
#
# 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: Currently, this is broken on RISC OS due to what appear to
# be bugs in UnixLib's pipe()/dup2() implementations. Until these
# are fixed and a new build of make is available, manually hardcode
# this to "riscos" (sans quotes). Please remember to change it back
# to "$(shell uname -s)" (sans quotes) again before committing any
# Makefile changes.
