#

# 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;
