2008-06-26 mkhexgrid

So I’m trying to build mkhexgrid.

1. libpng 👌

2. ignore libjpg for the moment 👌

3. FreeType 2 👌

4. libgd 👎 – I had to configure and build this inside a X11 session!

5. fortunately I already have libz! 😄

6. and I need the Boost C++ Libraries – I had too add -I/Users/alex/Source/boost_1_35_0 to CPPFLAGS in the Makefile

7. mkhexgrid 👌

=> libpng | FreeType | libgd | Boost C++ Libraries | mkhexgrid

The X11 dependency was surprising. I assume there’s a better way to do it, but I don’t know what it is. The error I got without X11:

Pyrobombus:~/Source/gd-2.0.36RC1 alex$  gcc -DHAVE_CONFIG_H -I. -I/usr/local/include/freetype2 -I/usr/local/include -I/usr/local/include/libpng12 -g -O2 -MT gdft.lo -MD -MP -MF .deps/gdft.Tpo -c gdft.c  -fno-common -DPIC -o .libs/gdft.o

I also noticed that SVG output required px units, which is not true. I submitted the following patch to version 0.1.1:

I just used copy & paste to use the same code that was available for PS output.

And finally this is the specfile I used for my map:

output=svg
outfile=hex-layer.svg
hex-side=1in
rows=8
columns=5
grid-color=B3B3FF
coord-color=B3B3FF
coord-size=10pt
coord-distance=0.7in
coord-column-start=21
coord-row-start=11

Yay!! 😄

I also found a python extension to generate hex maps in Inkscape via the Cartographers’ Guild thred index. There seems to be a bug that prevents the hexes from actually having coordinates. I’d have to investigate.
