# 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;
