1#
2# This Plan 9 mkfile is for ``easy'' building.
3# It worked for Ghostscript 8.53.
4#
5# This mkfile consists of two parts: the first part builds the gs executable,
6# the second unpacks the gs distribution and sets configuration parameters.
7#
8# Place this mkfile in the root directory of the gs distribution (the gsX.XX dir)
9# Edit the drivers list below, and mk fake-make to let gs configure
10# itself.  Fake-make doesn't actually build very much.
11#
12# Then you can run mk normally.
13#
14# Be sure to have the jpeg, libpng, and zlib subdirectories before starting.
15# These have been included in recent gs tar files so we do not maintain
16# our own anymore.
17#
18# Each time you change the drivers list you must rerun mk fake-make
19# before building.
20#
21# If you want to try out a new GS distribution, you should be able
22# to mk try-X.XX, test it out, and then do mk install-X.XX, where X.XX
23# is the version number (e.g. 5.70).  If outside BL, you may have to edit the
24# scripts to remove some local dependencies (e.g. calling outside and the
25# cpu call to thresher, alpha to make mips.h, alpha.h).
26#
27# If you get weird floating point errors, the culprit is usually the
28# halftone code, which converts double to uint, something 8c handles
29# incorrectly (treats as double to int).  Look in src/gshtscr.c for a line like
30#
31# 	sample = (ht_sample_t)((value+1) * max_ht_sample);
32#
33# and change it to one of:
34#
35# 	sample = (int)(vlong)((value+1) * max_ht_sample);
36#	sample = (ht_sample_t)(value * max_ht_sample) + max_ht_sample;
37#
38# depending on your preference.
39#
40# Also, recent versions of src/gxshade1.c cause the compiler to run out
41# of registers.  Brucee is looking into this.  In the meantime, use this
42# replacement:
43#
44#	private inline void
45#	make_other_poles(patch_curve_t curve[4])
46#	{
47#	    int i, j;
48#
49#	    for (i = 0; i < 4; i++) {
50#		j = (i + 1) % 4;
51#		curve[i].control[0].x = (curve[i].vertex.p.x * 2 + curve[j].vertex.p.x);
52#		curve[i].control[0].x /= 3;
53#		curve[i].control[0].y = (curve[i].vertex.p.y * 2 + curve[j].vertex.p.y);
54#		curve[i].control[0].y /= 3;
55#		curve[i].control[1].x = (curve[i].vertex.p.x + curve[j].vertex.p.x * 2);
56#		curve[i].control[1].y /= 3;
57#		curve[i].control[1].y = (curve[i].vertex.p.y + curve[j].vertex.p.y * 2);
58#		curve[i].control[1].y /= 3;
59#		curve[i].straight = true;
60#	    }
61#	}
62#
63# (the original includes the /3 in the big expressions).
