Compiling demo on Mac OS X

Daniel Brauer 27 Nov 2010 20:33

First, I'd just like to say that this looks like an excellent idea. It always bothered me that other contour texture generators used only binary data, because that's not usually what you have. The easiest format to find for both vector images and fonts is anti-aliased bitmaps.

I'm only just starting with this, but I can't get the demo to compile on my Mac. I've installed GLFW 2.7. It's been a while since I've compiled anything from the command line, so forgive me if I'm missing something obvious. Here's the output from gcc:

/bin/sh bundle.sh GLSL-contourtextures
gcc -o GLSL-contourtextures.app/Contents/MacOS/GLSL-contourtextures GLSL-contourtextures.c -lglfw -framework Carbon -framework AGL -framework OpenGL

The Makefile is for OS X 10.5 and GLFW 2.6. Sorry about that.
However, the solution is very simple. To make the demo
compile under OS X 10.6 with GLFW 2.7, all you need to do
is change "-framework Carbon" to "-framework Cocoa".
I think. That seemed to do the trick for me, at least.

GLFW removed its dependency on the dated Carbon API
in 2.7 and now uses the recommended Cocoa API instead.

Great, that worked like a charm! Thanks very much.

I'm working with the Unity game engine, and while writing shaders to display signed distance fields is fun and easy, I was disappointed that all the SDF generation tools seemed to be simplistic brute force approaches. I'm glad someone with a signal processing background has gotten involved. When I've got some time I'll put together a command line tool we can use in our pipeline. I'll drop by here again once I've done that.

Thanks again!

Good to hear that someone is putting this to good use!
If the GPL license for the SDF generation code is a problem
for your particular application, let me know. I'm reasonable.
