## This Plan 9 mkfile is for ``easy'' building.# It worked for Ghostscript 8.53.## This mkfile consists of two parts: the first part builds the gs executable,# the second unpacks the gs distribution and sets configuration parameters.## Place this mkfile in the root directory of the gs distribution (the gsX.XX dir)# Edit the drivers list below, and mk fake-make to let gs configure# itself.  Fake-make doesn't actually build very much.## Then you can run mk normally.## Be sure to have the jpeg, libpng, and zlib subdirectories before starting.# These have been included in recent gs tar files so we do not maintain# our own anymore.# # Each time you change the drivers list you must rerun mk fake-make# before building.## If you want to try out a new GS distribution, you should be able# to mk try-X.XX, test it out, and then do mk install-X.XX, where X.XX# is the version number (e.g. 5.70).  If outside BL, you may have to edit the# scripts to remove some local dependencies (e.g. calling outside and the# cpu call to thresher, alpha to make mips.h, alpha.h).## Recent versions of src/gxshade1.c cause the compiler to run out# of registers.  Brucee is looking into this.  In the meantime, use this# replacement:##	private inline void#	make_other_poles(patch_curve_t curve[4])#	{#	    int i, j;#	#	    for (i = 0; i < 4; i++) {#		j = (i + 1) % 4;#		curve[i].control[0].x = (curve[i].vertex.p.x * 2 + curve[j].vertex.p.x);#		curve[i].control[0].x /= 3;#		curve[i].control[0].y = (curve[i].vertex.p.y * 2 + curve[j].vertex.p.y);#		curve[i].control[0].y /= 3;#		curve[i].control[1].x = (curve[i].vertex.p.x + curve[j].vertex.p.x * 2);#		curve[i].control[1].y /= 3;#		curve[i].control[1].y = (curve[i].vertex.p.y + curve[j].vertex.p.y * 2);#		curve[i].control[1].y /= 3;#		curve[i].straight = true;#	    }#	}#	# (the original includes the /3 in the big expressions).## src/gxshade6.c also needs editing to remove use of the# vlong , operator on some architectures.## you may need to change this line in gs/src/gshtscr.c:# //      sample = (int) (value * max_ht_sample) + max_ht_sample;# to# 	sample = (vlong)(value * max_ht_sample) + max_ht_sample; </$objtype/mkfile BIN=/$objtype/bin TARG=gsOFILES=\	obj/gs.$O\	`{sed 's#^./obj/(.*)\.o .*#obj/\1.$O#' src/ld.tr >[2] /dev/null | sort} # The first driver is the default.DRIVERS=\	plan9\	bj10e\	bjc600\	bjc800\	cdj1600\	cdj670\	cdj850\	cdj890\	dfaxlow\	epsonc\	epswrite\	inferno\	jpeg\	jpeggray\	laserjet\	ljet2p\	ljet3\	ljet3d\	ljet4\	pbm\	pbmraw\	pdfwrite\	pgm\	pgmraw\	plan9bm\	pnm\	pnmraw\	ppm\	ppmraw\	pswrite\	stcolor\	tiffg32d\	tiffg3\	tiffg4\ HFILES=$objtype.h\	arch.h\ # enforce some startup conditionsx=`{mkdir obj >[2]/dev/null; mv jpeg/jmorecfg.h jpeg/jmorecfg.h.save >[2] /dev/null}  </sys/src/cmd/mkone UPDATE=\	/386/bin/gs\	/sys/man/1/gs\	/rc/bin/ps2pdf\	/rc/bin/pdf2ps\	/sys/man/1/ps2pdf\ update:V:	update $UPDATEFLAGS $UPDATE `{cat lsr}  CC=pccCFLAGS=-c -DPlan9 -D_POSIX_SOURCE -D_BSD_EXTENSION\	-I. -Isrc -Ijpeg -Izlib -Iicclib -DT$objtype '-DGS_INIT="gs_init.ps"'LD=pcc obj/gconfig.$O obj/gconf.$O obj/gscdef.$O\ obj/gscdefs.$O obj/iconf.$O obj/iconfig.$O: src/gconfig.h obj/%.$O: icclib/%.c	$CC $CFLAGS icclib/$stem.c; mv $stem.$O obj obj/%.$O:	jpeg/%.c	$CC $CFLAGS jpeg/$stem.c; mv $stem.$O obj obj/%.$O:	zlib/%.c	$CC $CFLAGS zlib/$stem.c; mv $stem.$O obj obj/%.$O:	src/%.c	$CC $CFLAGS src/$stem.c; mv $stem.$O obj #if possible, use genarch to build $objtype.h; it must run on same cpu type.#if not, try to use a default header for the target architecture.$objtype.h:	$O.genarch	if(~ $objtype $cputype) {		./$O.genarch $target		rm -f $O.genarch	}	if not {		if (test -r default.$objtype.h)			cp default.$objtype.h $target && chmod 664 $target		if not {			echo 'no default header file for target architecture'			echo 'run mk on the target architecture to build one'			exit false		}	} $O.genarch:U:	src/genarch.c	if(~ $objtype $cputype) {		rfork e		objtype=$cputype		pcc -DHAVE_LONG_LONG -B -o $O.genarch src/genarch.c	}	if not		status='' libinstall:V:	cp lib/* /sys/lib/ghostscript nuke clean:V:	rm -f *.[$OS] obj/* [$OS].out y.tab.?
